Technical Details of Technology
1. Brief on the technology: The laterite based filter assembly is designed to remove arsenic, iron and bacteria from ground water to provide low cost drinking water in arsenic affected areas. Naturally abundant laterite soil is used to prepare the filter media which has high arsenic adsorption capacity (32 mg/g). The arsenic removal media has a life of 5 years and the filter life can be extended for several years by changing the arsenic removal media every 5 years. The filter does not require any regeneration during its service life and also meets the toxicology leaching protocol (TCLP) for safe disposal. Domestic filter does not require any power for operation. The filter has been scaled up from 100 l/day to 10 kl/day.
2. Indicate the compliance to the relevant technical standard of the final technology output
(For example in case of potable drinking water IS 10500):
Yes, the technology complies with IS 10500 for potable drinking water. Parameters in filtrate: Arsenic <10 ppb; Fe <0.3 ppm; Total coliform: 0 CFU/ml.
3. If not applicable,then specify reason/other standards followed NA
4. Whether the technology is patented: YES
5. Nature of patent: National
6. Whether any pre-treatment required for adopting the technology: YES
i.Details of pre-treatment required for adopting the technology: approx 50 words. Pre-treatment required for removal of iron from raw water.
7. Nature of effluent disposal: Other(Specify)
i. Nature of effluent disposal Other(Specify): Arsenic removal media does not generate any effluent. However, iron removal unit requires backwash once in a fortnight. The effluent thus generated is passed through a soak pit containing treated laterite, gravels and sand bed.
