In recent year large amount of water and wastewater generated from various industries and produce organic matters and contaminated the water, this organic this organic compound in water poses serious problems to public health as well as environment. The advanced oxidation process (AOPs) is one of the advanced treatment method for wastewater remediation. In AOPs, ElectroFenton process (EFP) is o...

Cyanobacterial blooms often occur in aquaculture wastewater in China. A floating plant, water hyacinth has been widely used to treat this wastewater. Little is known, however, about bacterial community characteristics and the risk of potential pathogens in cyanobacteria-blooming aquaculture wastewater remediated by water hyacinth. In wastewater treated with water hyacinth, we used culture enume...

Reclamation and reuse programs are an indispensable part of integrated water resource management, particularly in arid and semi arid regions. Yet, the feasibility of sustainable application not only is relied on design, operation and maintenance of wastewater treatment plants, but also could be influenced by the economical and environmental aspects of reuse demands. This study is aimed to illus...

To understand wastewater quality transformations in the sewer system, a full-scale study focused on the characteristics of the influent wastewater in a middle-sized wastewater-treatment plant receiving only municipal sewage. The objective was to identify conditions in which prefermentation prior to the biological nutrient removal (BNR) process would be useful. Prefermentation aims at increasing...

Local utilities often face problems of local industrial wastes, storm water disposal due to existing strict regulations. For many local industries, the problem of wastewater treatment and discharge into surface reservoirs can’t be solved through the use of conventional biological treatment techniques. Current discharge standards require very strict removal of a number of impurities such as ammo...

A major challenge for the 21 st century will be the efficient use of all resources to minimize wastage. Lack of fresh water is becoming one of the largest and most universal of the resource problems that we face in the new century. This leads us to consider the options for turning wastewaters into useful resources, with recovery of the water for reuse. Therefore, wastewater has become an essent...

The disparity between volume of wastewater generated and treated has resulted in severe water pollution and eutrophication of the water bodies in most Indian cities. Constructed wetlands (CWs) present a low-cost wastewater treatment option; however, field scale studies with real life wastewater are limited. Eichhornia crassipes (water hyacinth), Typha latifolia (Typha) and Pistia stratiotes (wa...
