Coking wastewater from the process of coking, coal gas purification and the coking products refine, whose ingredients are complicated and inconstant, is hard to meet the standard of reclaimed water used for industrial water by secondary treatment. In view of this situation, the advanced treatment technique of coking wastewater was desired. The innovatory flocculation treatment was used to regen...

There is a gradual decline in soil fertility due to its continue use in farming. This necessitates developing new strategies of management programs to recharge soil with nutrients. From review it has been found that reuse of industrial effluents (wastewater) in agriculture can be a good mode to conserve soil nutrients. It may offer a way to fulfill irrigation water demands also. The major chall...

the treatment facility of albourz industrial city was established in 1999 at the southeast of albourz mountain with an area of 200,000 square meters. currently, 40,000 cubic meters of industrial wastes are treated daily utilizing biological method of activated sludge up to the second phase without chlorination in this treatment facility. then, the discharged wastes are directed toward the lower...

Currently, studies on hydropower systems operations primarily focus on multiple uses of water, i.e., water resources exploitation and control systems to satisfy human needs and demands connected to economic and social activities. Focuses include power generation, urban and industrial water supply, irrigation, navigation, leisure and recreation-related uses, flood control and water pollution con...

Many contaminants of interest in water and wastewater are particles, or are made into particles for removal. Typical municipal wastewater treatment plants include both primary and secondary sedimentation, and those with tertiary treatment likely have granular media filtration. Typical drinking water plants using surface water supplies have flocculation, gravity separation (sedimentation or flot...
