Desalination

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

The removal of nickel ions from diluted solution using some ion-exchange resins (Dowex MSC-1, Purolite C 100E, KU 2-8 and Dowex HCR-S) was studied. The purification process involved the use of an electrodialysis-type cell in which the centre compartment was filled with a packed bed of ion-exchanger

Composite cellulose acetate (CA) based membranes having a hydrophobic top layer made of polymethylhydrosiloxane (PMHS) were prepared with the aim of desalination of brackish waters from the Sahel region of Tunisia having a total dissolved salt content (TDS) of about 4100 g.m–3. The porous substructu

Operation of an experimental RO plant connected directly to a wind system without energy storage was studied. The data obtained confirm the wide spectrum of operation of the plant with respect to the power available and the operation of the system. The development of an RO plant for variable charges

This study focuses on measuring the process dynamics for the multistage flash desalination process (MSF) in an industrial unit with a capacity of 4546 m3/d. This is a novel addition to the literature because previous studies are limited to theoretical analysis of process dynamics or controller tunin

A thermodynamic simulation study was performed on the influence of greenhouse-related parameters on a desalination process that combines fresh water production using humidification–dehumidification with the growth of crops in a greenhouse. With the system under study, surface seawater trickles down

The high amino acid content (lysine, meteonin and tryptofan) of most leaf proteins makes them suitable as supplements for cereal flours, which are deficient in these amino acids. These proteins are used in cattle balanced foods. In this work, separative membrane technology, ultrafiltration (UF) and

Processes of desalination of seawater are intended to reduce the deficits in potable water both at present and in the future. Water desalination processes offer various environmental benefits (related to sanitation, water softening, quality of sewage effluents), but the process is also accompanied b

In the present work, the supported liquid membrane (SLM) technique has been applied to the desalination of saline water. A simple apparatus designed and constructed in our lab was used to conduct the experiments. Various factors that would affect the degree of desalination were studied and these wer
