Presently for water purification large treatment plants involving sedimentation, electrodialysis, reverse osmosis RO techniques are used which are not easy to employ without electricity. We have designed handy smaller/larger water filter pads that can be used in the home and water can be taken from any source. The Gupt Water Filter Pads can be easily fitted on bottles, utensils and easily remove trace, toxic ions from contaminated water. The GWF pads are recyclable, biodegradable. GWF Pads can easily remove metallic, radioactive and other ions like As, Pb, Zn. Cd, Fluoride from water and can be regenerated easily.
Huge GWF PADs are easily manufactured for various ions removal structure and can be employed for water supplies in villages from saline and brackish sources. For GWF Pads preparation no beads preparation, grinding and coating with toxic solvents are required. Another version of GWF can be employed to enhance water retention in the soil. There is no disposal problem as GWFPs are based on biodegradable materials. Filler inside GWFPs eliminates organic contaminants from water.
