This work deals with the feasibility of an olive vegetation wastewater purification process consisting of two consecutive steps: coagulation followed by membrane separation. The target of this work was to reach a purification grade of the wastewater compatible with the limits for the discharge into

Application of helical Couette Á Taylor flow (CTF) for reduction of membrane fouling in the process of radioactive wastes treatment was considered. The experiments were carried out with model solutions of cobalt ions (Co2+). Ultrafiltration process combined with complexation with polyacrylic acid or

Ultrafiltration is a modern technology used for the production of drinking water. Current research in this area focus on the reduction of production costs through the development of innovative plants. The aim of this work is to study ways to limit the fouling of hollow fibre membranes during dead-en

The fouling characteristics of ultrafiltration membranes used in drinking water were investigated when used alone and when used in an integrated biofilter-membrane system to treat a humic-acid laden solution. Membrane strands from sacrificial modules operating in parallel with bench-scale modules we

A pilot plant scale hollow fiber membrane system was developed for the removal of dissolved oxygen from boiler feed water via vacuum degassing process. Feed water was introduced to the shell side; a vacuum was applied to the lumen side of the hollow fiber. The effects of water flow rate, vacuum leve

An anaerobic thermophilic submerged membrane bioreactor was operated for 300 days, with a mixture of volatile fatty acids as substrate. Cake formation was identified as the key factor governing critical flux. Low levels of irreversible fouling were observed. During the first 60 days of operation a r

This study is aimed at elucidating the mechanism of the change of molecular weight distribution of EPS by bacterial activities after being attached on the membrane surface and the influence of EPS on the membrane surface on membrane fouling in a laboratory-scale MBR reactor. Change of EPS amount aft

The use of a submerged membrane bioreactor for the treatment of industrial oil contaminated wastewater was investigated using microfiltration hollow fibre membranes. The membrane bioreactor worked with a hydrocarbon concentration ranging from 600 to 1500 mg/L in a sub-critical flux regime. The sludg

The variation of quality and fouling properties of wwtp effluent over time influences the performance of ultrafiltration (UF) plants. This research reports three experiments in which the specific ultrafiltration resistance (SUR) measurement is applied to obtain more insight in quality variation an i

The paper presents the applicability of a membrane coupled anaerobic baffled reactor (ABR) for low-cost, waterborne sanitation to those communities with limited access to basic sanitation and are inappropriate for on-site, dry sanitation systems. This represents a challenge as anaerobic MBRs must be
