Online Domestic Water Purifier based on Polysulfone Ultra Filtration Membrane

  • Application Areas:
    • This device is used for purify the domestic water with respect to microorganism, colour, odour, suspended solids and organics. It is not only much less expensive but superior to existing devices in many ways and has following features:
      • Very effective as it removes bacteria to the extent of > 99.99% (4 log scale)
      • As the device filters out bacteria, no dead bacteria in product water
      • Removes complete turbidity and produces crystal clear water
      • Does not need electricity or addition of any chemical
      • Highly strong (both chemically and mechanically) membranes giving high life (3-5 years)
      • Almost maintenance free except occasional cleaning of suspended solids which deposits on membrane surface and this does not take more than 3-4 minutes time.
      • Device works between the hydrostatic heads (5 psig to 35 psig) and can produce about 40 litres of pure water per day at about 10 psig head)
  • Technology Transfer Fee: Rs. 50,000/-
  • Infrastructure and manpower requirements
    • A small room with window air-conditioner/dehumidifier is needed to coat ultrafiltration membrane unit. All the steps in the presented technology are manual in nature and hence does not require electrical power for process. Constant source of water is needed to produce and test the membrane device.
    • One Chemist and one technician to observe the process and two skilled workers would be adequate to produce about 25 water purifiers per day.More

Membrane Assisted Defluoridation Process for Safe Drinking Water

Note:UF Membrane technology is available separately for technology transfer on chargeable basis.

  • Application Areas:
    • This technology is useful for removal of fluoride from ground/surface water to provide safe drinking water free from primary contaminant like fluoride as well as secondary contaminants like aluminum and microorganisms.
    • Technology can be adopted at both domestic and community level and may work without electricity.
  • Technology Transfer Fee: Rs. 25,000/-
  • Infrastructure and manpower requirements
    • The development of fluoride decontamination process requires a small laboratory with few common equipment like pH meter, analytical balance and common glassware.
    • One Chemist and one skilled worker would be adequate for the purpose.More

Fluoride Detection Kit (FDK) for Groundwater

  • Applications
    • The procedure is as simple as adding a specified amount of kit reagent to the water sample to be analysed and identifying the color developed. The color develops almost instantaneously and the distinction can be made with the naked eye, the water sample can be immediately categorized as being safe, marginal or unsafe for drinking from fluoride point of view. Even a layman can perform the test. The kit can be an excellent tool for individual/community level identification of fluoride free groundwater sources.
  • Technology Transfer Fee: Rs. 4,00,000/- only
  • Infrastructure and manpower requirements.
    • A laboratory room size (3m X 3m) is required with 2 glass beakers (250 ml), 1 measuring jar (1L), 1 platform balance, 2 HDPE cans (15L) equipments.
    • One technician for preparing the reagent and one chemist for carrying out the reagent quality assessment by checking with standards.More
