1) Absorbent is cost effective.
2) Arsenic removal capacity is highercompared to expensive activated alumina,iron oxide coated sand, iron basecommercial adsorbent, etc.
3) Adsorbed both As(III) and As(V) speciesand less sensitive to pH compared toalumina media.
4) No interference from sulphate, chloride,magnesium and iron ions are observed.
5) Works over wide range of pH 5.5 to 8.0.
6) Non-hazardous waste meets TCLP (toxicitycharacteristics leaching protocol)requirements.
Benefits over other absorbents
Key Features of ‘OS’

VAS BROS.
Low cost of the filter media compared to other adsorbents.
Power is required only to operate the pump to lift water intooverhead tank. Flow in the filters is by gravity.
Removal of arsenic, iron and pathological contaminationtogether in a single unit.
Arsenic concentration of filtrate is always within the WHOdrinking water permissible limit (10 ppb).
Capacity of community based filters ranges from 5K to 50KL/day
Extremely long life of the filters (Five years or more).
No regeneration or backwash of the filter medium isrequired during its lifetime.
No leaching of the spent media – meets TCLP protocol (filtermedium can be safely disposed).
Easy operation and maintenance.

OS Filtration Process
Proposed Community BasedWater Treatment Plant is to filterout Arsenic from Drinking Waterin Arsenic affected areas of WestBengal.
Major Components of the WaterTreatment Plant Shall be:
• Submersible Pump for lifting thewater
• Solar Water Lift for lifting thewater to the Raw Water Tank
• Raw Water Tank & StorageWater Tank
• Lateritic based Arsenic Filterfulfilling the desired outputcapacity
• Commissioning of the Plant

Benefits are:
• Cost Effective
• Robust
• Safe from Theft / Burglary
• Lesser Maintenance
• Fully Automated
• least maintenance
• 100% safe dump of media post it life

Additional Possibilities
• An online monitoring systemwhere Government / Agenciescan monitor the performanceof all Water Units online.
• Tracking and hence ensuringthe Arsenic Free waterconsumption by everyhouseholds.
Remote Monitoring• To avoid misuse of water, and to
make sure that every householdis getting adequate Arsenic Freedrinking water, We can install aCard Vending Machine.
• Water Cards will be distributed tothe households with adaily/weekly capping of waterconsumption

“Our technology has 4 times higher absorption capacity than other
available technologies. This technology is already approved by Arsenic task Force,
Govt. of West Bengal, Department of Science & Technology, Govt. of India”

"Department of Science and Technology is proud to be associated with low cost
locally available material based indigenuous technology for arsenic
removal. We hope the technology would lead to benefit the masses and address
the arsenic menace effectively“~ Dr. Sanjay Bajpai, Director,
Department of Science & Technology, Government of India.

Extremely low cost, life of the filter being as high as 5 years, non-regeneration of Arsenic, and minimal maintenance are
the USP of our technology.
