Pretreatment

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

The bioconversion of lignocellulosic biomass requires two main steps: cellulose and hemicellulose conversion (hydrolysis) to monosaccharides followed by fermentation of the monosaccharides into the desired products. Pretreatment of the lignocellulosic biomass is required to hydrolyse hemicellulose a

Three different water treatment ultrafiltration (UF) pilot plants were investigated to treat algae-rich reservoir water. Coagulation, coagulation–sedimentation and coagulation–sedimentation–filtration were applied prior to UF respectively. Based on the permeate water quality and the specific flux of

The use of ultrafiltration (UF) is receiving more attention for drinking water treatment, but its fouling remains a problem. Reservoir water was selected as raw water during pilot study. Worldwide drinking water reservoirs may contain algae, which pose a threat to drinking water treatment. UF membra

The essential point for a successful seawater reverse osmosis (SWRO) plant is pretreatment that provides consistent and high-quality feed to SWRO membranes. Advances in membrane technology and increasing requirements on water quality have stimulated the use of ultrafiltration (UF) for SWRO pretreatm

To reuse pretreated water effluent of the El-Nile Company for the food industry in Egypt, NF and RO membrane separation techniques were investigated. Two sets of experiments were carried out by using laboratory separation unit with maximum pressure of 7 bars and pilot plant membrane separation unit

The effect of different hydraulic cleaning methods was investigated in terms of flux decline and resistance using the cross-flow UF unit. The use of varied production intervals, varied ratios of periodic relaxation and the use of a periodic high-rate crossflow were investigated. This cleaning method

Water situation of the rural area of Damascus has been investigated in details including water resources, consumption, shortage and quality. Due to the shortage of potable water, a suitable RO plant was suggested. Full details of its design including its needed pretreatment are presented. Water prod

Cross-flow microfiltration alone or associated with ultrafiltration or coagulation was conducted to investigate the efficiency of this process in the reducing of chemical oxygen demand (COD) and proteins (Npr) in the waste waters produced from cuttlefish conditioning and freezing process. The study

Nanofiltration membranes (NF) have applications in several areas. One of the main applications has been in water treatment for drinking water production as well as wastewater treatment. NF can either be used to treat all kinds of water including ground, surface, and wastewater or used as a pretreatm
