One of the requirements for environmental engineering, which is currently being considered, is the removal of ethylene glycol (EG) as a hazardous environmental pollutant from industrial wastewater. Therefore, in a recent study, a moving bed biofilm reactor (MBBR) was applied at pilot scale to treat industrial effluents containing different concentrations of EG (600, 800, 1200, and 1800 mg L-1 )...

The present work deals with the continuous flow systems based on renewable resource biosorbents towards green removal of various categories chemical pollutants from aqueous media. opening discussions are focused on: (a) resources; (b) (c) dynamic biosorption. After these, resources reviewed according to parameters breakthrough curves. Subsequently, targeted systematized and analyzed following c...

The U.S. Environmental Protection Agency (EPA) requires that stormwater be controlled to the maximum extent practicable through the use of stormwater control measures. These regulations are enforced by state and local governments, who often require the use of SCMs to comply with total maximum daily loads (TMDLs). State and local governments also provide guidance on SCM design and assign load re...

The operating pressure of the first-stage DTRO and removal efficiency COD, BOD, TP observed within 180 min at pH 6.5, 7, 7.5, respectively, then mechanism analysed optimization methods recommended. results show that reached its fastest increasing rate which grew from 32.13 to 32.66 Bar rapidly. all major pollutants increased steadily with uptime before stability. maximum rates were 97.9%, 97.36...

Raw clays, extracted from Bana, west Cameroon, were modified with semiconductors (TiO2 and ZnO) in order to improve their depollution properties the addition of photocatalytic properties. Cu2+ ions also added clay by ionic exchange increase specific surface area. This insertion Cu was confirmed ICP-AES. The presence TiO2 ZnO detection anatase wurzite, respectively, using X-ray diffraction. comp...

in this study a sample of bentonite obtained from semnan mines, was modified by a surfactant to prepare an organoclay with high surface area. bet analysis showed that the modification increased its surface significantly. the prepared sorbent was used for removal of dyes and other organic pollutants from a waste water obtained from ekbatan textile company. adsorption was studied in various times...
