Fouling remains a major issue for all membrane applications. This study investigated anti-fouling applications for a side-stream membrane bioreactor (MBR) fed with glucose-based synthetic wastewater. Air sparging, backflushing and high cross flow velocity (CFV) were investigated as anti-fouling stra

A large-scale ultrafiltration (UF) system integrated with coagulation was applied to produce drinking water from the highly turbid Taihu River. This UF installation could produce 10,000 m3 drinking water per day. In this study, the effect of FeCl3 coagulant on the performance of the UF system was ev

A solar still is a simple desalination unit, but typical configuration is a sealed box with an angled glass top. Sunlight shining into the box heats water or liquid, causing it to evaporate. The moisture condenses on the relatively cool glass cover and runs down the sloped surface for collection. In

Boron compounds are used in the variety of products manufacturing and are introduced to the environment in the form of waste. Here the feasibility of the boron removal from wastewater by electrocoagulation (EC) is studied. Aluminum and iron were simultaneously used in the reactor as materials for ca

A complex membrane procedure with enhanced effectiveness for fruit juice concentration was proposed. The method was realized by an ultrafiltration-membrane osmotic distillation (UF–MOD) sequence, treating red fruit juices of great dietary value. A three-dimensional ultrafiltration membrane test equi

Bench-scale dissolved air flotation (DAF) of Tagus River surface water (Valadas, Portugal) was investigated as pre-treatment for spiral-wound module nanofiltration (SWNF). Before the DAF, a coagulation/flocculation of the surface water was performed using aluminium sulphate, ferric chloride and chit

A novel type of submerged rotating membrane bioreactor (SRMBR), with a rotatable, rounded, flat-sheet membrane module fixed on the axes and moved by an electromotor, was used to treat synthetic sewage. The SRMBR was operated under constant transmembrane pressure (TMP) condition and a standard TMP-st

The current study developed oil spill hazard contour maps for the prediction of oil spill travel times and critical wind directions in association with major strategic desalination plants in United Arab Emirates. Five desalination plants were selected along the UAE coastline as potential destination

Zinc has been permeated through a flat-sheet supported liquid membrane, using 2-ethylhexylphosphoric acid mono-2-ethylhexyl ester (PC-88A) in kerosene. Liquid–liquid experiments were conducted as a function of aqueous pH (1–6) to establish optimum conditions for both extraction and stripping of the

The present study deals with the characterization and treatment of bleach plant effluents generated from Indian varieties of wheat straw or bagasse or hardwood/non wood materials. Spent bleach liquor (SBL) was generated by the chlorination and extraction of unbleached pulp under controlled condition
