A bench scale submerged microfiltration system coupled with high concentration of PAC (powdered activated carbon) was applied in order to purify a river water containing secondary effluent. The system was operated with four different modes: Run-1, -2, -3 and -4. The PAC concentration was set at 0, 4

Endocrine disrupting chemicals and pharmaceuticals represent two classes of emerging contaminants that are ubiquitously present in municipal wastewater effluents. Some of these contaminants have been shown to impact aquatic organisms at trace concentrations (i.e., ng/L). Moreover, the public has exp

In order to develop efficient photocatalytic TiO2 films and membranes for application in water and wastewater treatment and reuse systems, there is a great need to tailor-design the structural properties of TiO2 material and enhance its photocatalytic activity. Through a simple sol–gel route, employ

The phase inversion technique was used in this study to prepare polyethersulfone membranes. After optimizing the synthesis factors, like the relative air humidity, the concentration of the polymer and the used solvent, nanoporous membranes were obtained. Characterization of these membranes indicated

PEEK-WC HF bioreactor permits us to reproduce the Hypericum perforatum immunomodulatory effect on human peripheral lymphocytes as observed by previous in vivo studies. In fact, St. John’s wort modulates linfocitary response suppressing metabolic activities. This investigation underlines the ability

Poly(phenylene oxide) (PPO) membranes with sulfonic groups were prepared by two methods: plasma-initiated surface grafting of sodium styrenesulfonate or chemical sulfonation (with chlorosulfonic acid) of PPO, followed by membrane preparation from the modified material. The presence of ionic groups g

A new hybrid process for treating wastewater, combining membrane microfiltration and flotation, was investigated. The hybrid process combines the advantages of both membrane separation and flotation: the flotation cell removed a large proportion of suspended solid particles while the membrane module

Pilot- and full-scale experiments were performed to elucidate the feasibility of using a modified cationic polymer for capital and operational cost savings. This membrane performance enhancing product is referred to as MPE50TM. Since the low flux caused by low water temperature is one of the most im

The capability of a radial basis function neural network (RBFNN) to predict long-term permeate flux decline in crossflow membrane filtration was investigated. Operating conditions of transmembrane pressure and filtration time along with feed water parameters such as particle radius, solution pH, and

Gas-filled membrane absorption has been used to remove cyanide from different cyanide containing wastewaters. In this study, cyanide removal from an industrial praziquantel wastewater has been investigated. The wastewater contained a high cyanide concentration and turbidity due to the presence of li
