Climate change makes people to be aware about the environmental pollutions in aspect of Air, Water and Soil components. The environmentally aware countries have forced the other countries to implement the stringent effluent standards for disposal into water stream / water bodies. Hence, modern technology like the application of membrane separation (Micro or Ultra filtration) technique with biol...

In this study, Cabernet Sauvignon red wine was subjected to reverse osmosis and nanofiltration processes at four different pressures (25, 35, 45, 55 bar) two temperature regimes (with without cooling). The aim obtain concentrates with a higher content of phenolic compounds antioxidant activity determine the influence membrane types (Alfa Laval RO98pHt M20 for NF nanofiltration) operating condit...

In conventional activated sludge (CAS) involving aerobic biological processes, the retention of silica nanoparticles (SiO2 NPs) has no detrimental effect on chemical oxygen demand (COD) and ammonia nitrogen (NH3–N) removal. However, for the membrane bioreactor (MBR) system, which is also based on the activated sludge process in addition to the membrane separation process, it has implications no...

The National Egyptian Agenda 2030 recently adopted the concepts of sustainable cities, mitigating and adapting to climate change. This study responded these by treating sewage reuse it in softscaping recycling sludge reduce energy consumption support heating systems producing biogas. Of limitations this study, focuses on a compound propose model increase sustainability cities. used many technol...

UV-induced grafting technique was used as a flexible method for surface modification of Polysulfone (PSf) ultrafiltration (UF) membranes in order to prepare hydrophilic nanofiltration (NF) membranes. Flat sheet Polysulfone (PSf) ultrafiltration membranes were prepared via phase inversion method. N-methylene-2-pyrrolidone (NMP) and polyethylene glycol (PEG) of three different molecular weights (...

Abstract Sustainable development is based on environmental, social, economic, and technical dimensions. In this study, the sustainability of wastewater treatment techniques in urban areas Iraq was assessed using a multi-criteria decision analysis (MCDA)/the weighted sum model (WSM). The performed 13 operating plants 10 provinces, Iraq, questionnaire sheet with assistance 52 specialists Ministry...

Two commercial activated carbon were functionalized with nitric acid, sulfuric and ethylenediamine to induce the modification of their surface functional groups facilitate stability corresponding AC-supported iron catalysts (Fe/AC-f). Synthetized Fe/AC-f characterized determine bulk composition (elemental analysis, emission spectroscopy, XPS), textural (N2 isotherms), structural characteristics...

White-rot fungi, unlike bacteria in conventional activated sludge system, can degrade wide varieties of textile dyes. Their large scale implementation, however, has been impeded due to lack of appropriate reactor system that can sustain stable performance under non-sterile environment. In this study, contrary to virtually complete decoloration of an azo dye (Acid Orange II, 100 mg L(-1)) in pur...

In order to recover lithium from brine with a high Mg2+/Li+ ratio, positively charged nanofiltration (NF) membrane was prepared by depositing polydopamine (PDA)-coated graphitic carbon nitride (g-C3N4) as the interlayer (PDA-g-C3N4) and interfacial polymerization (IP) of polyethyleneimine (PEI) trimesoyl chloride (TMC) carried out. Under optimal conditions, water contact angle composite is only...
