In this work the structure and the installation of a flexible and low cost SCADA system is presented. An ordinary PC with the appropriate interface and software operates the system. The system was installed to an old desalination plant in parallel with the existing old type conventional automation s

The Palestinian Water Authority (PWA) as a regulator for the water sector in Gaza and the West Bank had initiated a strategy to build small-scale RO seawater desalination plants (600–1250 m3/d) using the donor community funds as a supporting source of potable water to be operated and managed by the

UNO has estimated fresh water deficit as 230 billion m3/y by the end of 21st century. It has been reported that about 10,000 people die every day and thousands suffer from scarcity of fresh water, as it has become one of the most critical problems in our planet. Desalination is an ideal solution for

In this paper, we investigate the possibility of adopting the Once-Through (OT- MSF) design in place of the conventional brine recycle (BR-MSF) design for the future, large scale desalination plants. It was assumed here that efficient anti-scale chemicals would be available. Thus, a top brine temper

This article deals with water removal from oil-in-water emulsion by an ultrafiltration membrane at different transmembrane pressures. The membrane intrinsic resistance and gel resistance are analyzed and determined based on the resistance-in-series theory. The experimental results show that the effe

Transport of phenylalanine (Phe) through a supported liquid membrane (SLM) containing di-(2-ethylhexyl) phosphoric acid (DEHPA) as carrier in a spiral-channel module was studied. The value of the molar flux of Phe through SLM increases with the velocity of the feed phase in the channel. However, soo

Simultaneous membrane based solvent extraction (MBSE) and membrane based solvent stripping (MBSS) of 5methyl-2-pyrazine carboxylic acid (MPCA) in hollow fibre contactors with solvent containing trioctylamine (TOA) have been studied. An effective transport of MPCA was achieved. The analysis of mass-t

A method of covering a cellulose support with a semi-permeable membrane is discussed. This covering was carried out in a continuous manner with very good reproducibility. Due to the expected application and specific properties of the membrane obtained, a non-standard method of evaluation of the qual

The presented paper is a peer-review of plasma action on porous polymer membranes. Considering the plasma medium the discussion is split in two parts: i) the first shows some effects caused by action of non-polymerizing gases, i.e. polymer etching and/or alteration of surface character, and, ii) the

This work focused on the evaluation of the influence of incorporation of non-stationarity to the model of a batch circulating system for membrane-based extraction and stripping (BCSMES). Mass balance equations of the transferred component in a hollow-fibre (HF) contactor either for steady-state cond
