The disposal of domestic wastewater without any treatment into the drainage systems is considered a source of pollution threatening the population. Industrial waste water discharge to the environment is one of the environmental problems which must be controlled. Current mainstream technologies for treatment of domestic wastewater such as activated sludge and tertiary nutrient removal are too co...

Treatment process models are efficient tools to assure proper operation and better control of wastewater treatment systems. The current research was an effort to evaluate performance of a submerged membrane bioreactor (SMBR) treating combined municipal and industrial wastewater and to simulate effluent quality parameters of the SMBR using a radial basis function artificial neural network (RBFAN...

Industrial wastewater contains a lot of pollutants and therefore needs special treatment processes. The treatment process may contain mechanical, biological, chemical, physical and physiochemical such as Coagulation – Flocculation process. The goal of this experimental work was to investigate the effects of coagulationflocculation and dissolved air flotation as a hybrid process of industrial wa...

Industrial aquaculture wastewater contains large quantities of suspended particles that can be easily broken down physically. Introduction of macro-bio-filters, such as bivalve filter feeders, may offer the potential for treatment of fine suspended matter in industrial aquaculture wastewater. In this study, we employed two kinds of bivalve filter feeders, the Pacific oyster Crassostrea gigas an...

Membrane bioreactors (MBRs) can be broadly defined as systems integrating biological degradation of waste products with membrane filtration. They have proven quite effective in removing organic and inorganic contaminants as well as biological entities from wastewater. Advantages of the MBR include good control of biological activity, high quality effluent free of bacteria and pathogens, smaller...

Introduction: The development of an appropriate model for the quality control of an industrial wastewater treatment system can save the time as well as the cost. This study was performed to determine an appropriate model in order to predict the COD and TKN parameters by BOD5 and NH4+ in the Meybod industrial estate wastewater treatment plant (WWTP).  Materials and Methods: This descriptiv...

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...

water resource scarcity, population growth, pollution of surface and groundwater by discharging toxic wastewater and subsequent diseases may raise the necessity of reusing and treatment of wastewater. cyanide is one of the toxic materials which can be found in some industrial wastewaters. strict laws set by international bodies have forced industries to work on developing efficient cyanide remo...
