Wastewater treatment processes are inherently dynamic because of the large variations in the influent wastewater flow rate, concentration and composition. Moreover, these variations are to a large extent not possible to control. The adaptive behaviour of the involved microorganisms imposes further difficulties in terms of time-varying process parameters. Mathematical models and computer simulat...

In recent years, membrane technology has been widely used in wastewater treatment and water purification. Membrane technology is simple to operate and produces very high quality water for human consumption and industrial purposes. One of the promising technologies for water and wastewater treatment is the application of forward osmosis. Essentially, forward osmosis is a process in which water i...

INTRODUCTION Anaerobic technology have been successful applied for industrial waste water treatment. High reaction rate per unit volume by retaining the biomass in the reactor independently of the incoming waste water flow and concentration. Often high volumetric loading rates in the order of 10 to 40 kg COD/m.d are used. High rate anaerobic biological reactors may be classified into three broa...

Background and Objective: Coagulation, which is carried out by mixing coagulants such as alum, ferric chloride and poly aluminum chloride PAC with raw water, is one of the main processes in conventional water treatment plants. Sludge from this process contains high amounts of coagulants with high economic value. Therefore, if these coagulants are recovered, in addition to reducing the risks rel...

Abstract Introduction: Innovative processes for treatment of industrial effluents containing dyes and heavy metals are often used to reduce the toxicity of these compounds in order to reach the refining standards. Recently, a special focus on innovative processes took place for physical and chemical removal by new absorbent, biomass absorption, membrane filtration, radiation, and electrochemica...

The blooming of the world’s human population and transition diet into a more westernized, high-protein has accelerated production slaughterhouse wastewater (SWW) as number meat processing plants (MPP) increased in past few decades. Conventional treatment processes (CTP) used treating SWW, such anaerobic processes, membrane electrocoagulation, have significant limitations, low efficiency, tenden...

Membrane processes are used in various felds such as the environment, agriculture and different industrial sectors. These clean techniques are often adopted for directed processes such as treatment, recovery, valorization and separation. In this review article, the theoretical principles and the different classifcations of liquid membranes, such as supported liquid membra...
