Due to the growth in the human population globally, it is noted that various industries have also grown. The need for an excess supply of water and the generation of high effluent quality upon proper treatment technologies has become a necessity. These two crucial needs can be achieved with the aid of membrane bioreactor (MBR) that has been proven to be effective in removing organic and inorganic matters as a biological unit for wastewater treatment. MBR plants are created by integrating the biological process with membrane filtration which possesses numerous benefits if compared with conventional methods such as activated sludge; MBR is widely used for municipal and industrial wastewater treatment. This review addresses basic concepts of MBRs plants and subsequently provides information on the recent developments of each part related to MBR plants. The characteristics of the bioreactor treatment process is discussed in detail, and then a comprehensive review of the membrane separation process is examined. The fouling phenomena as a main obstacle to widespread MBRs plant is presented in detail with recent fouling mitigation methods. The efforts of a number of novel MBR processes are summarized. In order to tackle the existing limitation of MBRs to be practical on a larger scale, the existing challenges and future research efforts are proposed.

The development of novel wastewater reuse technologies appears to be a thriving area of research. Adsorptive membranes are considered among the promising technologies that exhibited efficiency and competence in water reuse. They have the potential of removing different types of emerging pollutants from wastewater that cannot be removed via conventional methods. These membranes are attractive because of the dual advantage of adsorption/filtration mechanisms and by virtue of their various types and configurations. The use of adsorptive membranes tackles several issues including fouling, process cost, adsorbent regeneration, adsorption capacity, membrane permeability, rejection rates, and selectivity. This review is devoted to discussing adsorptive membranes and their fabrication techniques, as well as presenting their various types and classifications. The challenges associated with their application are also reviewed. Their classifications can be established based on either the type of the adsorbent used or their polymers matrix. The major challenges are fouling and identifying the right filling materials. The review also identified the great potential of using these membranes in removing emerging pollutants.

A Microbial Fuel Cell (MFC) is a process in which a microorganism respires and captures the electrons that normally passes through the electron transport system of the organism and produces electricity. This work intends to present the different operating parameters affecting the efficiency of a Microbial Fuel Cell (MFC) process. To study the performance of the process, various materials for the cathode and anode rods with similar size and chape including, copper, aluminum, carbon cloth, steel and brass were considered to determine the combination that leads to the best results. Moreover, different oxidizing agents such as Copper Sulphate and Potassium Hexacyanoferrate were considered. Furthermore, the effects of shapes, sizes and distance between electrodes on the current and voltage were investigated. The power outputs between electrochemical and microbial cells were recorded. In addition, the power, whether expressed as voltage or current, was measured at different conditions and different cell combinations. The power is directly related to the area, volume of the bacterial solution and supplying air and stirring.

Ion exchange membranes, specifically resin technology, lie at the heart of electrolytically conductive systems used in the treatment of wastewater. This chapter deals with ion exchange deionization and the effect of resin amount as well as the concentration of acid and base on the product conductivity. The strong acidic cation polymeric exchanger resin is commercially called MERCK 104765 cation exchanger IV with capacity greater than 3.2 mmol/ml, while the strong basic anion polymeric exchanger resin is commercially called MERCK 104767 anion exchanger III with capacities greater than 1.0 mmol/ml. Water conductivity, as an indicator of regeneration efficiency, was monitored over time at the different conditions and scenario. In general, it was observed that the conductivity decreases with time until one point is reached and then starts to increase as a result of resin saturation. It was also noticed that the lowest conductivity is achieved when using 1-vol% NaOH and 5-vol% HCl in the cathodic and anodic resin tubes, respectively, and that water conductivity increases with the increase in the amount of water being used. The amount of resin significantly impacts the deionization efficiency; more ions are removed as the amount of resin increases.

Chlorination in wastewater treatment is regarded as a complicated process due to its ammonia and nitrite content. Chlorine added to such systems reacts with ammonia undergoing episodes of complex reactions resulting in the chlorination breakpoint behavior. Most of the available chlorination mechanistic models are not easily applied which has restricted their practical utilization in treatment plants. In this study, a new mechanistic model for the chlorination breakpoint in ammonia-nitrite systems is suggested with a user-friendly interface and to be applicable with conditions occurring in wastewater treatment plants. The model was validated against laboratory studies reported in the literature and was also applied to forecast chlorine residual in a wastewater treatment plant in the region. The model simulated both experimental and field data reasonably well.
