phosphorus is an important nutrient for plant and microorganisms growth, thus has an important role in creating eutrophication of surface waters. the present study has investigated poly aluminum chloride efficiency on orthophosphate removal by coagulation and chemical precipitation process in municipal wastewater in west wastewater treatment plant. this bench scale study was performed on influe...

Saline municipal wastewater treatment is a challenging environmental issue in coastal cities, due to the discharge of saline water into the sewers. The present research article focuses on the phytoremediation of high saline municipal wastewater by Ruppia maritime, a widespread plant which can be found in saline medium such as traditional fish ponds, estuaries, tidal flats, salt pans, coastal pa...

Sludge production is an avoidable problem arising from the treatment of wastewater. The sludge remained after municipal wastewater treatment contains considerable amounts of various contaminants and if is not properly handled and disposed, it may produce extensive health hazards. Application of aquatic worm is an approach to decrease the amount of biological waste sludge produced in wastewater ...

Background & Aims of the Study: The most important compounds in hospital wastewater are antibiotics, disinfectants, anesthetics, radioactive elements, static cytotoxic agents, other chemicals and hazardous materials that caused to be different domestic sewage. The purpose of this study was the evaluation of performance of extended aeration biological system in pollutants remova...

WEST++ is a modelling and simulation environment for any kind of process which can be described (in an Object– Oriented fashion) as a structured collection of Differential Algebraic Equations (DAE’s). Currently however, WEST++ is applied to Waste-Water Treatment Plant (WWTP) design and optimization. In particular, the IAWQ1 model [1] is the basis for a simple model of the dynamics of a basic WW...

aerobic digestion was useful for mixed sludge of west ahwaz sewage treatment plant. results showed that after 12 days 38% of tvs reduced. this meets the environmental standards. after 19 days detention time in the bioreactor, cod, vss, tvs, tss, ts, were 40 ,56, 54.5 ,50.4 ,44.7 percent respectively. kd coefficient was,0.173day-1. aim of this bench scale study is determination of aerobic digest...

Water supply is a critical issue in the Middle East, particularly in the West Bank and Gaza Strip (Palestine). Water resources are scarce due to the arid climate and the population growth while water resources management and development is complicated by the ongoing Israeli occupation. There is a critical lack of sanitation in the West Bank. Only 45% of the Palestinian population is connected t...
