In this review, adsorbents used in wastewater treatment and their technical feasibilities are reviewed. Adsorbents are classified as natural adsorbents, and the adsorbents obtained from industrial and agricultural wastes. They all were compared with each other condensing the metal binding capacities, costs and metal removal performances in waste water treatments. Although commercial activated c...

Many regions around the world are currently facing water shortages which inhibit development and economic growth. Although some of the allocation problems faced by these regions can be partially alleviated by improving agricultural irrigation efficiencies, another means for substantial water savings involves the reuse of municipal and industrial discharges to offset freshwater demands. In many ...

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...

The world’s chemical industries face formidable environmental regulatory challenges in treating their wastewater effluents. The present work aims at highlighting the various industrial wastewater treatment technologies currently available including physico-chemical and biological processes as well as constructed wetland and conventional or advanced oxidation processes. Activated carbon prepared...

Heavy metals pollution has become a more serious environmental problem in the last several decades as a result releasing toxic materials into the environment. Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical processes were used for the treatment of domestic, industrial and agricultural effluents. The commonly used conventional biological treatmen...
