Sand Control . An original polymer technology is proposed for the consolidation of poorly cemented sandstone formations. This technology is based on the adsorption of an "environmentally friendly" water-based polymeric film on pore walls, which can efficiently prevent the erosion of the cement of the rock under high flow rates.

Treatment of water has a great influence on the use of water for domestic use both in rural and urban areas. Slow sand filtration involves the use of beds of sand for the filtration of water. The reason for designing slow sand filter for rural water treatment is to make treatment of water easy and qualitative. This research involves the use of three tanks, filter beds, filter media and ...
