Abstract The cost-effective production of lipase by microorganisms are currently needed. bioconversion agro-industrial oily wastes as an alternative substrate for in the form solid-state fermentation (SSF) or submerged (SmF) would hold a potential role future biotechnology. There some studies revealed that yeast, fungi, and bacteria choice such from genera Aspergillus, Penicillium, Rhizopus, Ca...

Abstract In recent, oily wastewater as a special contaminant has seriously impacted the ecological environment. this work, nature and green materials are used to prepare SA-PVDF membrane taking freezing salt out super hydrophilic modifying. Therefore, obtained exhibited good flux, excellent recyclability, superior separation efficiency. More importantly, filter was green, eco-friendly, cost-aff...

Smart materials with reversible wettability have attracted a lot of attention for application in sewage treatment. In this work, pH-responsive polymer was prepared via the one-step free radical polymerization 3-(trimethoxysilyl) acrylate and 2-dimethylaminoethyl methacrylate. The obtained then coated hydrogenated styrene–ethylene–butadiene–styrene block copolymer to endow material switchable su...

A simple two-stage chemical solution process is reported, to deposit a superhydrophobic film on copper foams with view be employed in oil absorption or filtration procedures. The first stage includes the growth of silver layer increase micro roughness and second one evolves modification using stearic acid. whole time-saving, cost effective versatile. UV-Vis spectroscopy was determine optimum de...

This work aims at selecting a suitable strategy to accelerate the start-up of the anaerobic treatment of olive mill wastewater (OMW) and to enhance the biogas production. Two anaerobic sludges were tested in toxicity and biodegradability batch experiments: biomass acclimated to oleate (BAO) and biomass non-acclimated (BNA). The results showed that the resistance to OMW toxicity was higher for t...

BACKGROUND Discharging the oily wastewater in the environment causes serious problems, because of the oil compounds and organic materials presence. Applying biological methods using the lipase enzyme producer microorganisms can be an appropriate choice for treatment of these wastewaters. The aim of this study is to treat those oil wastewaters having high concentration of oil by applying lipase ...

A membrane sequencing batch reactor (MSBR) treating hypersaline oily wastewater was modeled by artificial neural network (ANN). The MSBR operated at different total dissolved solids (TDSs) (35,000; 50,000; 100,000; 150,000; 200,000; 250,000mg/L), various organic loading rates (OLRs) (0.281, 0.563, 1.124, 2.248, and 3.372kg COD/(m(3)day)) and cyclic time (12, 24, and 48h). A feed-forward neural ...
