  • Dear Mr. ZahidWhat is the brim filter and what is it supposed to do? If any water source contains iron salts, it is invariably in the form of water soluble iron salts. When this water is pumped out and exposed to air, the oxygen in the air converts the dissolved salts into insoluble salts which separate out as a brownish sediment. The conventional method of removing these dissolved salts is to expose them to sprinkle the pumped out water into a tank whereby it gets mixed thoroughly with air and...

  • I am from Kerala. We are also facing problems with iron in our well water. We are thinking to install a birm filter. Is it necessary to install a sand filter before or after the birm filter? Can the birm filter alone filter the precipitate or is any post filtration is required?Looking for your response.Regards,Zahid

  • Dear Mr Giby George,Please ignore the last two paras of my reply to your problem as these paras actually refer to the problem of yellow water from the borewell faced by johnbio85.Indukanth Ragade

  • Dear Johnbio85By mistake, the second part of my comment to your problem has come in my comment on the problem of Mr. Giby George who faces a problem of oily taste in his borewell water.This suggestion is to see if you can put a casing pipe of smaller diameter into the borewell upto a depth of 60 ft so that the iron containing water upto this depth cannot enter the borewell and see if the water you get thereafter becomes iron free.Sorry for the mix up.Indukanth Ragade

  • (Comment received from Mr. Indukanth Ragade over email)Dear Mr. Giby GeorgeIn the event the oily stuff is petroleum, you will have made history by hitting oil at such low depths!!You mention that the water has an oily taste. Does this mean that you cant see visually any oil but the water has a funny taste? If you keep a bucket of water pumped from your borewell in a bucket, do you see any floating oil layer? Is there a possibility that the connecting pipe may have had some oil (or whatever the...

  • Hello Sir,I own an apartment at Urapakkam, Chennai. The water is so salty and the color is very much yellow. But I have seen that nearby flats are having relatively good water. What are the options we have to get a better/clear water? Please provide the products or other options.Thanks,Ram, Chennai

  • I reside in Thoraipakkam, on the Old Mahabalipuram Road (OMR), Chennai. My residence is about 1 1/2 kms east of the OMR. None of the residents here either have a borewell/well at home. A few tried them about 6 yrs back and due to the salinity, gave up using them and later by their experience, none other, including me, has risked. I've been here for the past 5 years and now, the tankers demands are going to unmanageable levels. I intend going in for a borewell and the prospective borewell digger...

  • Dear NavinMost probably your borewell has iron salts in it. Water, if drawn from it fresh, will be colourless and on keeping become pale white first, then yellow on keeping and then brown. If this water is stored further, there will be a brown layer at the bottom and the rest of the water will be clear. The problem is likely to be more acute is summer.You mention that the water had 1800ppm. This is reasonably good drinking water if the microscopic iron content is removed.What is the demo you...

  • From the data given by you, I would say that you should get good water like the others in the neighbourhood if you raise the suction pipe to that level. I have had two positive experiences of improvements  by doing this:one in Balajinagar in Royapettah, an area prone to water with iron salts and another in West Mambalam. If others are getting good yields of water from that level, you too should get good yield. Let me know your experience.My ph no is: 2834 3506; isragade@yahoo.comIndukanth...
