Background & objectives: Nowadays, according to membrane-based filtration processes; the use of substances such as antiscalants that prevents the formation of deposits during the treatment process, is very important from industrial point of view. This study aimed to synthesize styrene-maleic anhydride copolymer (PSMA) using the radical polymerization method and to investigate the factors and pa...

In this report, experimental investigation of waste water treatment by reverse osmosis to enable its reuse in cooling tower is presented. A polyamide spiral wound RO membrane followed by three filters as RO pretreatment (two activated carbon and one cartridge filter) and samples of Tehran refinery treated waste water have been used. The effect of operating conditions such as pressure difference...

Desalination and wastewater treatment technologies require an effective solution for brine management to ensure environmental sustainability, which is closely linked with efficient process operations, reduction of chemical dosages, valorization brines. Within the scope desalination reclamation, a circular system consisting seawater reverse osmosis (SWRO), membrane distillation (MD), forward (FO...

one of the most important concerns in tehran municipal landfill is the production of leachate and its potential for water resources pollution, this study was undertaken to examine feasibility of biological and physico/chemical treating of high-strength landfill leachate that was collected from tehran municipal landfill. average cod of the leachate in aerobic submerged membrane bioreactor is 680...

Before investing in any optimizing technology for the recovery and reuse of brine resources, it is importance to study full physicochemical characteristics brine. In current study, Qatari seawater reverse osmosis (SWRO) were fully investigated. The intends lead a better understanding nature SWRO given economic significance country that can be benefited from recycling reusing various components....
