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...

Since most of the water used for brewing becomes wastewater, reduction wastewater streams is great importance industry. Anaerobic membrane bioreactors incorporating forward osmosis membranes (FO-AnMBRs) could provide an energy-efficient solution treatment brewery while recovering and simultaneously producing biogas. The start-up period two lab-scale FO-AnMBRs fed with real (Rreal) synthetic (Rs...

Growing uncertainty in the future availability of freshwater sources has led to an increase installations for desalination seawater. Reverse osmosis (RO), currently most widely adopted technique, caused environmental concerns over high associated greenhouse gas emissions and generation large amounts chemicals-containing brine. Significant consumption electricity RO is additional challenge, part...

The recent development in oil and gas industry increases the production and consumption of oil. The enormous amount of oily wastewater produced is urged to be treated to prevent humanity and environment from being threatened. Membrane technology is an appealing alternative for oily wastewater treatment due to its design simplicity, energy efficiency and environmentally benign approach. In this ...
