Of course sea is our best sink. We made a few preliminary experiments to know the quality of water. Field trial data to prove that the Filter-Tablet system is suitable to eliminate arsenic from groundwater. Scientists from School of Environmental Studies went to six arsenic affected districts during 1993-1995 to see how the technique works in field. Table 4 to 9 shows analysis of arsenic and other common parameters.
Results show arsenic is removed and the quality of water is potable.
Analytical report from various other agencies about suitability of our arsenic removal system. After being satisfied by our laboratory and field trial we sent the system to various National recognised scientific institutes for its evaluation. The agencies evaluated our system were National 1. Thailand Bureau studied our system themselves in field where we installed our system in W. Bengal. From our field report we can comment now that Field Trial through actual users is the sure test of a technology.
