In this paper the humidification–dehumidification desalination process is studied and its performance optimized using mathematical programming. An advantage of this method is consideration of the simultaneous effect of various parameters on process performance. An NLP system model is solved for thre

This paper reveals the results of a study aimed at identifying the seasonal influence of dust deposition on a large field of evacuated tube collectors associated with a multiple-effect distillation plant on the performance of the plant. The system is located near the city of Abu Dhabi, UAE, and the

Hydrophilic polymers with pendant functional groups form polymeric supports for various technological applications such as ion exchange, reagents, anchoring agents and catalysts. In the present study, 2- acrylamido-2methyl propane-1-sulphonic acid (AAmPSA) was polymerized by chemical initiation meth

The objective of this work was to replace the conventional pretreatment of reverse osmosis by coupling ultrafiltration with adsorption onto activated coffee-like adsorbent material. Adsorption was achieved on activated carbon prepared from a waste of coffee. A protocol of preparation is described as

The study shows the results of studies concerning the hydraulic permeability of ultrafiltration and hybrid in-line coagulation–UF (without sedimentation) systems during the treatment of water containing higher concentrations of organic matter. The calculation of UF permeability was made employing a

It is important to search for substitutes for chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs) with a desirable combination of physical properties to meet the needs of specific applications, but ultimately with no harm to the environment. Therefore, a method for the computer-aided desi

This paper summarizes a feasibility study for a wind–diesel hybrid system for Star Island, New Hampshire, that also includes a desalination system component. In addition to supplying electricity during the peak demand summer months, this system attempted to balance the seasonal mismatch between wind

Climate change and endeavours towards a sustainable society have brought the interest of wood-based biorefineries to the fore. Lignin is the main energy carrier in chemical pulp mills. Today, the heat value of lignin is commonly recovered in the recovery boiler of the mill. However, interest in the
