Title of Process/ Know-how/ Product/Design/Equipment
Process based on polymer-based ion-exchange resins for the removal of arsenic from ground water and arsenic detecting kit
Application/Uses/Problem being addressed
Resin: Removal of arsenic from water
Arsenic detecting kit: A test kit to detect arsenic semi quantitatively in ground water up to 10 ppb
Salient Technical Features including Competing Features/ Impact
1. Ion exchange resin technology for the removal of arsenic from ground water
2. Economical and easy to use arsenic detection test kits to analyse the presence of arsenic in water
TRL Level & Scale of Development:
Functionalization of resin can be achieved @20Kg/batch in 100 litre RBF equipped with heating and cooling assembly. 65 domestic and 12 community scale unit capacity of 25LPH and 250LPH respectively were deployed at arsenic affected rural areas of 24-Parganas (N), West Bengal, to provide arsenic free water.
Test kits were also supplied along with plant to analyze field water samples.
Business scope & opportunity (in terms of scale, cost, market etc.):
The technology is ready for technology transfer and can be implemented on commercial scale. The product has high demand in water purification to provide arsenic free water.
The test kits are easy to use to analyse the presence of arsenic in water.
Environmental Considerations:
The process is quite economical; field tested and also clean in true sense
Status of Licensing:
Ready for licensingStatus of Commercialization:
Not applicableMajor Raw Materials Needed
Resin: Monomers like methyl methacrylate, methacrylic acid, ethyleneglycol dimethacrylate, divinyl benzene, aliphatic amines, ferric chloride, hydrochloric acid and caustic alkali etc.
Test Kit: Whatman filter paper, mercuric bromide, rosaline, nitric acid, ethanol, PVA, sulphamic acid, zinc metal dust etc.
Major Plant Equipment and Machinery Required
