A patented cycle for water desalination and power generation was evaluated with regard to thermal efficiency and water production. The inventor of the patent claimed that the patented cycle provides a thermal efficiency of 41%, which is higher than current combined water and power generation steam p

Olive oil production results in important quantities of wastewater containing large amounts of total solids and organic carbon as well as low oil concentrations. This paper describes the treatment of olive mill wastewater (OMW) by combining an ultrafiltration (UF) technique and an advanced oxidation

Technology for solar desalination has been studied for a long time as a process friendly to the environment and also energy saving. We found a new aspect by diverting attention from industrial mass production systems to the consumer’s life-style and resource recycling problems. Thus, desalting solar

This is the last paper in a series of three parts entitled “Optimal design of hybrid RO/MSF desalination plants”. This research is concerned with exploring the feasibility of hybridization of multi-stage flash (MSF) and reverse osmosis (RO) technologies in order to improve the performance characteri

With the aid of atomic absorption, a systematical and analytical evaluation method called Taguchi’s quality engineering has been applied for the separation of copper ions from a solution using a laboratory electrodialysis set-up to evaluate the optimal experimental conditions and hence to achieve th

The studies of acid purification and base purification via bipolar electrodialysis are presented. The process of acid recovery involved spent solutions of acid (HCl or H2SO4) and iron salt obtained in the course of conventional electrodialysis. Bipolar electrodialysis yielded an acid solution concen

A dissolved air flotation (DAF) process is used for removing oil from oil–water emulsions. Operational conditions that increase shearing and disturbance of liquid during the operation of large-scale DAF systems can significantly reduce oil removal efficiency. Objectives of this study were to evaluat

The paper is designed to present an overview of the seawater pollution in coastal and near coastal waters in South Mediterranean countries — in the region in general and Libya in particular. The objective is to assess the possible pollutants, study the harmful effects and the impact of pollutants du

The experience of the Canary Islands is unique in the world. In a very limited territory, all types of technologies and combinations can be found. The tertiary treatment installed in the waste water treatment plant of Barranco Seco (Gran Canaria, Canary Islands) has been designed with an ultrafiltra

The state of water was studied by the method of differential scanning calorimetry in initial membranes and the membranes following their use in a water desalination process based on the baromembrane and electrodialysis methods. The analysis of data obtained makes it possible to determine the contrib
