Resin: Removal of arsenic from water
Arsenic detecting kit: A test kit to detect arsenic semi quantitatively in ground water up to 10 ppb
1. Ion exchange resin technology for the removal of arsenic from ground water
- No electricity required
- No skill is required to operate
- Resin developed, efficiently removes both the forms of arsenic present in the water
- Reusable after regeneration
- Easily separable after use
2. Economical and easy to use arsenic detection test kits to analyse the presence of arsenic in water
- Easy to use
- Colorimetric detection of arsenic in water
- Have shelf-life of ~2 years
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.
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.
The process is quite economical; field tested and also clean in true sense
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.
Resin Plant: Pumps, fittings, column, Overhead tanks and receiver tank etc. Test Kit: Glass bottle with lid, brown bottle to keep test strips
The process is quite economical; and field tested to provide arsenic free water
Resin preparation and arsenic test kit making; Depends on the scale of manufacturing; Will be available on request
