Volatile organic chemicals (VOCs) contaminate 90% of the U.S. aquifers‚ but 2% of samples had unsafe VOC levels. The US found that ⅓of the 26k industrial waste ponds didn’t have liners to prevent toxic liquid wastes from seeping into aquifers. The EPA had completed the cleanup of 297k of the 436k underground

Sewage treatment plan Sewage treatment is the process of removing contaminants from waste water and household sewage‚ both run off (effluents)‚ domestic‚ commercial and institutional. It includes physical‚ chemical‚ and biological processes to remove physical‚ chemical and biological contaminants. Its objective is to produce an environmentally safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). Origins

industry is one of the major industries in India causing water pollution. The manufacture of paper yields a significant quantity of waste-water. It is estimated that 273–450 m3 of water is required to produce 1 ton of paper and about 60– 300 m3 of wastewater is discharged (Subramanium 1976; Thompson et al.

“Primary Treatment of wastewater consists of the removal of insoluble matter such as grit‚ grease‚ and scum from water.” (Manahan‚ 2010) The first step of this treatment involves screening which prevents large solids from getting into the treatment process. This is followed by an oil and grease trap in which oil skimmers are used to separate oil and grease from the effluent. The separated oil and grease are then given to recyclers. From this the water is transferred to the collection tank and from

Water Reclamation and Recycling As our population continues to grow‚ many begin to raise questions about how (or even if it’s possible) to provide enough water to support this rapidly growing population. With our population recently reaching 7 Billion‚ it seems that finding the answer to this has become such an imperative as to be compared to our global energy crisis. As more and more research is conducted‚ one viable answer seems to keep resurfacing‚ water reclamation. While many proponents
