They said silica is at only about 20 parts. Desalination in bore well water analysis (in ppm): The county utility says our water is not hard (calcium levels aren't high). Because of the range of particle size, silica removal has no "one size fits all" solution. KINDLY TELL ME HOW TO REMOVE THIS SILICA FROM SBA? The condensate is pure water having almost zero conductivity. Osmosis membranes, using water collected from the Mint Farm, and their abilities to remove Silica are discussed below. More likely it is reactive, soluble silica. Still, if you don't trust your lab analysis, you'll have to have some other person or service re-do it -- you can't possibly rely on an internet vote to override an actual chemical analysis :-). A. Silica can be removed from raw water easily with standard demineralization techniques. Normally silica is present in a weak acidic form. Q. I want to know whether we can reduce reactive silica of 2 ppm in RO2 treated water by doing distillation. And I assume a reverse osmosis system for the whole house would be no better? For optimum silica reduction, a sludge-contact unit (shown in Figure 7-8) is used. These flakes then absorb silica. Methods of Silica Removal From Water There are different methods to remove silica from water, and the process varies depending on whether the goal is to remove dissolved silica or colloidal silica. Q. Q. I would like to know if there is a method of removing silica from boiler blowdown having a concentration of 150-200 ppm to below 5 ppm? Ion exchange will remove this as long as the anion resin is the strong base type. That number doesn't surprise me one bit! Silica in deionized water can easily be reduced to 20-50 ppb. To minimize search efforts and to offer multiple viewpoints, we combined previously separate threads onto this page. The product works by using a microbe that accepts silica through the cell wall, giving enough surface area and charge to physically remove the silica. "palette": { High temperature softening greatly improves silica removal. Sludge blowdown is proportioned to raw water flow. As for silica's presence in the steam, above about 27BARg, silica is able to evaporate and travel as a gas/vapour with the steam... boiler water carryover is not necessary for this 'silica carryover' to occur, as the silica has become volatile at this temperature.. Many thanks to Rachel and all others who have provided information helpful to homeowners. Silica is also called silicon and is a … Cl : 5424 To remove silica from the corals, take a water pipe and put a small hose on it. However, if this is DI water, then further treatment is needed for most uses. 2. Why not try out some clean-rinse additives (cascade platinum, jet-dri, etc, but read the packaging to see if they are safe for skin contact or ONLY in the dishwasher) in your dish/mopping up water and see if the situation improves before committing to anything pricey? PAC (Poly aluminium chloride) is not approved. We are using FeCl3 as coagulant of 25 ppm and Poly electrolyte of 1 ppm. Lime softening utilizes the addition of lime (calcium hydroxide) to remove hardness (calcium carbonate … The water has low hardness, less than 10 mg/L, low pH 4 to 5, and relatively high soluble iron, hydrogen sulfide and aluminium. watertreatment Make sure you check that the softener is rated for Silica removal. This reaction works on hardness causing minerals such as calcium and magnesium, creating flakes of these minerals. 5 mg/L of silica in the permeate with only 28 mg/L in the feed is not very good rejection. [last name deleted for privacy by Editor], -- this entry appended to this thread by editor in lieu of spawning a duplicative thread, Thirumalai Chemicals Ltd - Ranipet, Tamilnadu, India, Boiler Water Treatment Chemist - Brisbane QLD Australia, ©1995-2021 finishing.com, Inc., Pine Beach, NJ, How Google uses data when you visit this site. Please address whether there are reasonably priced ways to reliably filter out silica for an individual house, other than reverse osmosis. Has been quite effective with silica. Removal of silica was, on average, 94% before breakthrough, which was at about 50 bed volumes. I appreciate it. Corrosion Chances of increasing SiO2 in SBA EXHAUST of SAC? Any other solutions? All that being said, it's quite likely that a couple strategic under-counter softening systems (found at large home improvement stores) to at least take care of a couple lines, like the one into the dishwasher, will be more cost effective. The other items are cleaned in the dishwasher and don't have noticeable etching or deposits like glassware does so I'm not concerned about treating water for the dishwasher. Inside the boiler the concentrations of silicate incense and they get deposited as “silicate scale“, which very hard, quite adhering, very poor conductor of heat and extremely difficult to remove even with chisel and hammer. "background": "#237afc" We are continuously open cbd and every hour ibd for 20 sec. When questions are presented as requests for clarification of suggestions that have been offered, they usually elicit enthusiastic response; but if earlier answers are just blown off, and questions are posed as "start over for me because I can't be bothered putting in any work to try to appreciate what you wrote", the thread often dies). But that's another conversation entirely). window.cookieconsent.initialise({ Please keep on posting on this topic. Removal of silica in water Can affected by : Using magnesium compounds during the hot lime-soda process of softening and recirculating the sludge. (required), chemical treatment An easy way to test if scaling might be silica is to wipe the affected area with white vinegar. Thanks! What are my best AND least costly options? Nor shower in it, or use it in a fish tank. In order to get the salts out of the crude oil, it first has to be mixed with demineralized water (condensate in our case). Q. Silica present in water, tests say Silica (mg/L) 5.72 If silica concentration is near or more than saturation of silica, then there are only two ways. USE SILICA REMOVAL SPECIAL TECHNIQUES. RO is an option but to centrally treat the water will cost over $15,000. Nice answer. 4)" Is it healthier to drink our minimally treated spring water which always passes the utility's required testing or to drink RO water from which minerals are removed?" Capex is much higher than chemicals, but you make it up in opex. Particles smaller than .015 microns can become lodged inside the membrane pores, occluding them and causing an earlier than expected loss of production. Sir, There were a couple of gems in that monograph. You *could* self-pack instead, but then you have to be willing to do the work of the VERY messy cleanout, and know what to do with the used resin beads (pro tip: start by not spilling any on the floor, or you'll be channeling a toddler trying to walk on ice for the first time, but as a normal sized human with further to fall), which might actually have accumulated enough metals out of the water by this point to be considered a RCRA waste, but you won't know that without lab work, which is another expense of getting set up. I am not talking about silica seen with the naked eye floating in water. Tina Nenoff, a chemist at Sandia National Laboratories, said: “When you have silica buildup, heat transfer is a problem, clogging is a problem and corrosion is a problem. Figures 2, 3 and 4 are curves showing the effect of sludge magnesium concentrations on the removal of silica from water at different ter- Co peratures. In actual practice, silicates of calcium and magnesium acts as cements and they even bind together other particles present inside boiler into a very hard scale. We are consuming high ppm of lime and dolomite in the range of 950 ppm each to reduce the level up to 50 - 60 ppm. How Google uses data when you visit this site. Try electrocoagulation. The other items are cleaned in the dishwasher and don't have noticeable etching or deposits like glassware does" The previous forum questions/answers, while interesting, relate mainly to treatment of large water treatment systems or for industrial use. Please give me solution. Our main shower is travertine and the silica deposits aren't noticeable there like they are on the dark granite around the sinks. Silica, in amounts ranging from less than 1 to over 100 ppm, is found in all natural water supplies.In rain hail and snow, silica content range from 1 to 2.8 ppm. Figure 5 is a composite curve based on Figs. 2) One person with a home well said that it would cost $15,000 for whole house reverse osmosis. "background": "#fff", If the plant from which you want to remove the silica is a little strong, then you can gently wipe it with a cloth. I also use Ozone at bottling time. IBD = intermittent blowdown. 3c) Would the 'waste' water be safe for grass and plants? That's why the water purification companies whose marketing is aimed at the retail/residential market can get away with charging what they do for basically taking on all the headaches themselves! Aluminium? I don't quickly see any WHO limits for silica, but how much more study would have to be done depends on your situation. And you can usually install them yourself! If silica in dm water, why? Q. Dear, in our boiler the silica contains 0.53. We use condensate as make-up water to electrical desalting vessel. A. Silica leakage is lower if you regenerate the DI system counter-currently and regenerate the anion exchanger before exhaustion as determined by conductivity and also more frequently. It is frequently found in water supplies as a colloid or in ultra fine particulate form. Silica can exist in water as relatively large particles, known as silica granules or granular silicates. water filter What is the reason of SiO2 increasing? At a concentration of < 1 mg/L, I doubt that it is colloidal silica. 3a) We are in a rural community served by a county spring, treated only with minimal levels of chlorine. Thank you again, If you read earlier discussion in this thread, one of the things you might notice is that with water purification there is an efficiency of scale (oh no did I just make a bad mineral deposits pun? TDS : 9407 waste water Quick questions, quick answers as I shove a cold cheeseburger in my face, here goes!!! If you are responsible for a public water supply, you'll need to learn the standards inside out. Why does steam carry silica and where does it come from if FEED WATER SILICA is zero? Thanks for the entertainment included in your postings, Rachel :-), Q. 1) "is it still true that, as was stated by another person, that silica, whether in colloidal or reactive (soluble) form, can be effectively removed to very low levels by reverse osmosis?" But this "invisible" silica leaves white deposits on surfaces. Operation at a higher pH increases the degree of ionization of the silica and its rejection, but increases the vulnerability of your system to hardness fouling. SiO2 : 85 Can you post some technical information about this technology so that readers can view it. } Kindly inform us to remove silica in high alkalinity water. oh yes I did!). Can you provide us some suggestion to reduce the silica concentration in final steam? Ion-exchange across a resin bed would work. Anybody know whether silica stays in water phase or it can be partially transferred to the oil phase during the mixing in desalter vessel? A. Silica can be removed from raw water easily with standard demineralization techniques. I mean by distillation method can we reduce reactive silica from 2 ppm to below 0.02 ppm. Chlorine Max. water conservation For high silica waters as seen in Mexico, Hawaii or other sandy areas where levels are 50-60 ppm or higher, the ion exchange and RO options are more troublesome because you may exceed solubility limits for one, and also you are more likely to have significant levels or non-ionic colloidal silica. Normally these methods work well for most well or surface waters where silica is below 15-20 ppm. water plant Can anyone suggest the most feasible and practical solution in my case? remove silica so that deposits do not occur on bathroom fixtures, The water temperature is around 20 to 25 degree. The most common approach is lime softening, which is a process where calcium hydroxide (lime) is added to water to remove hardness. Which of these silica forms can I remove by microfilter? Sir...I am facing a big problem with new High Pressure Boiler cleaning. We add Chlorine Dioxide at the source killing most of yeast & moulds. })}); Not a lecture hall but a roundtable with a seat for you! It can also be reduced by coagulation method such as in a clarifier system. When the resin is spent, you call the service provider (I can guarantee you will not be trying to self-pack your media canisters) and have them swap out the canister(s) for fresh. As per Dan Cooper, Mg helps in removal of silica; but in my research it proved wrong. A bit bulky to take up a lot of under counters space but realistic if required. For each ppm of SiO2, generally, 4.2 ppm of sodium fluoride is required. Quick Facts About Silica: Silica is short for silicon dioxide. water supply In my RO feed the COD is 700 ppm, so my membrane fouls instantly. A. "text": "#237afc" The internet is largely anonymous & unvetted; some names may be fictitious and some recommendations might be harmful. total counts are low. Sir, my plant is ion exchange and anion silica is 0.456 mg/Lit. In some cases for very large flow rates you can remove silica with lime softening techniques. A. Hi Jayeshkumar. Normally silica is present in a weak acidic form. 3a) "They said silica is at only about 20 parts. What is the tolerable levels of Silica in the rejects of RO? At lower than neutral pH values, there may be a significant amount of non-ionic, soluble silica that can pass through the membranes. Lately we had a little silica (3.2 mg/L) show up in that make up stream. Or What is the concentration limit of Silica in Rejects which will foul the RO membranes? Analysis. water desalination Still getting large growths of algae after about 20 days. My concern is whether there is any extra treatment required for SiO2 removal? I do appreciate any information. note: Please get back to us with what magazine and what issue if you remember. 1) One gentleman from Australia wrote in 2007, 'Oxidized silica atoms can and do exist in many chemical and mineral forms, hence a process that works in one location might not work in another' Despite this, is it still true that, as was stated by another person, that silica, whether in colloidal or reactive (soluble) form, can be effectively removed to very low levels by reverse osmosis? While silica removal from water is vital for drinking water application utilizing membrane treatment processes, its removal is also important in industrial processes as well. Waste Water Treatment water scale NOT including labor or resin matrix. So right now we are not able to eliminate the cause for such silica contamination but we need to figure out how bad can be the effect of silica-containing condensate to the desalting process as well as to downstream equipment: oil heat exchangers and reboilers. In silica gel, the physically adsorbed water can easily be removed when kept in an air oven at temperature around 150 degree centigrade temperature for 2-3 … 1.run your R.O AT LOWER RECOVERY ACCORDINGLY. I have noticed a lot of Silica build up on the samples in the chambers lately. }, ----Readers: Were you looking for Removal of Silica Stains instead? sewage To remove silica stains a product needs hydrofluoric acid or at least fluoride salts of some sort, and is therefore dangerous stuff. Please reply at the earliest. This causes loss in efficiency to the extent of about 10 per cent in a week’s time. It's going to be a big initial investment. I deal with water used in our boiler and domestic use.The silica levels are very high about 100 mg/l after being passed through a softening plant. At about 40 kg/cm steam pressure, about 5 ppm of silica dissolves in steam and goes along with it. Colloidal silica will show up very little even in the chemical test, as it is a polymer and quite unreactive. Q. Your operating cost per gallon of water produced on a homeowner sized system is going to be higher than what we pull off out here in the industrial settings, where we have large purchase contracts for consumables (resin) that we get on bulk pricing, and run in facilities that already have means to legally dispose of this type of waste, and skilled labor to operate it. SILICA REMOVAL. One big problem is, we notice that the Chlorine Dioxide (0.4ppm) raises the pH to 7.6 and also reacts with silica forming a white precipitate (floc like) and I think this causes inefficiency in killing the algaes. CBD = continuous blowdown I'm designing a plant to bottle further treated municipal water but I'm not sure with the silica levels (10 mg/L) whether they are too high or ok. What are the WHO limits? More cost effective than chemical flocculation. 2) "One person with a home well said that it would cost $15,000 for whole house reverse osmosis. " Water Purification That's why you mostly see these systems pop up in industrial settings (that, and seriously no one in their right mind would want to shower in deionized water. We use it to remove a whole variety of suspended solids, emulsified oils, bugs, etc. Does silica contribute to water conductivity. silica removal using Mg 2+ When magnesium is present in well water and when its pH level is adequate, it will precipitate with some of the silica when carbonates are being removed. A. Hi Musa. Besides having a flat, awful taste, you actually are better off with a certain level of minerals in your drinking water. maintenance Can anybody tell me about silica removal process? Reverse osmosis (RO) will remove dissolved silicates, but removal of silicates prior to RO is desirable to reduce the risk of fouling. Q. Hi, in DM water with silica 0.02 ppm. 4) Is it healthier to drink our minimally treated spring water which always passes the utility's required testing or to drink RO water from which minerals are removed? Our spring water contains 68 ppm of Silica. Do you think under sink RO systems would be effective/realistic? Mg : 910 Thank you. If you want to have less silica in your DI water, there are several possible ways to accomplish this. A silica concentration of up to about 120 mg/L can be tolerated in most RO concentrates. This makes sense. Q. But I want to know about preventing the deposits to begin with. Silica finally get deposited on turbine blades, nozzles, thereby it distorts their shapes. Rustam. I try to convince them to base exchange soften before RO, so that we can fine tune the RO for silica rejection by increasing pH of RO feed...(increasing pH of RO feed without softening first will rapidly scale membrane with Calcium). Disinfection water treatment plant But if you search Amazon or other sites you will find water stain removers that claim to remove silica; then you can look up their SDS and you will find the fluoride listed. Can anyone explain why did this happen and is there anything where alkalinity comes into picture? A discussion started in Does your industrial facility need to remove silica from its feed water? ----Ed. Values of 25-50 mg/L are not uncommon. This is not lime scale because products for removal of lime scale have no effect. It's just a LOT of things to do and keep track of! A. Hi Chirag, remove colloidal and dissolved silica, which can be found in high concentrations in brackish water. H2SiF6 (which is strongly ionized), by adding calculated quantity of sodium fluoride ( NaF ). If the silica is reactive silica, then Reverse Osmosis is the most practical method to remove it from the water supply. Total Dissolved Silica 114g/m3 as SiO2 (silicon x 2.14 by calculation) ©1995-2021 finishing.com, Inc., Pine Beach, NJ - About finishing.com - Privacy Policy The presence of silica and its ability to foul membranes limits the use of silica bearing waters for desalination and when used, it has many economic penalties. We can also add a chloride or sulphate Mg salt. If the water contains silica and other unwanted ions and water purity is also an importance, then a Continuous Deionizing system is much more appropriate. Water Treatment Also, how to reduce COD? Shirley. chlorination The water is then passed through hydrogen exchanger. Silica in bore well is 110 ppm, T. Alkalinity is 415 ppm, Total hardness is 150 ppm. 5. A. The HFS60 membrane can either be installed downstream or upstream of the demin plant. Silica Source of Silica Silica (SiO 2) is an oxide of silicon, and is present in almost all minerals: It is found in surface and well water in the range of 1 - 100 mg/i.Silica is considered to be colloidal in nature because of the way it reacts with adsorbents. A. For improved silica reduction, sludge is recirculated from the cone back to the top of the unit. RO is replacing Demin in many plants, but is not the "magic bullet" that the boiler owners were told it would be.. A. Q. Hi folks, Q. I have a well, used for our house, that has high level's of silica (103 mg/L). We want to decrease the chemical consumption. A. 3b) I wash glassware and flatware by hand. Q. You'd have a contractor set up a system that includes a pump, a prefilter, one or more ion-exchange canisters full of resin, a postfilter, a holding tank, various pressure monitoring gauges, pipes, hoses, and a conductivity sensor that will indicate when the system is not able to process your incoming water any more due to the resin being saturated or 'spent'. bathroom and kitchen faucets, stainless steel sinks, counter tops, glassware, etc. I am trying to learn more information on removal of silicon from water. Silicon 53g/m3 And spring water tastes so much better anyway (unless one is unfortunate enough to share an aquifer with my parents who have a wicked sulfur problem and the well water smells like eggy toots until it's been run through their whole-house permanganate water softener...). Q. Hi there, Designing RO of 12 M3/ Hr. plant treatment water Q. Dear sir, Once it goes into your boiler, it is hydrolysed under high temperature and high pH of the boiler water and appears as if by magic, as suddenly it is monomeric and able to react with the test method. There are anti-scalents that are reasonably effective for silica, but even with these, the silica in the RO concentrate will probably be limited to about 200 ppm. If you suspect that silica is present in your household water supply, it is always best to contact a water professional for an evaluation. } I am generating dm water of pH 6.4, conductivity 1.2 µs/cm. Ved. We appended your inquiry to a long and detailed thread which offers some great explanation of silica in DM water. Big RO systems like that are ubiquitous on ships -this is the experience I've had with them, working the commercial fishing fleet in the Bering sea, and where I discovered how atrocious they are for showering. In super-heaters, water dries up and dry steam carries forward the silica. Think of the cost of setting up a photovoltaic system capable of running your whole house. Colloidal silica refers to the silica the doesn’t dissolve in solution and instead stays suspended within water. elements_selector: "iframe" Quick notes on what it is and how it works: Good luck... and oh yeah... don't shower in deionized water :), Q. Since silica can accumulate on machinery surfaces and cause hard mineral deposits known as scale, many facilities work to remove this contaminant before it causes production issues.
