The objective of this study was the application of a high-performance compact reactor (HCR) in the treatment by activated sludge of a load polluted by hydrocarbons. The tests were carried out in the laboratory with synthetic water containing fuel oil as the principal source of carbon. A solution ric

This paper briefly discusses the current industrial practice for assessing the scaling potential of sparingly soluble salts and suggests a more theoretical approach which is expected to provide more accurate results. This theoretical approach is based on the use of Gibbs free energies of reaction fo

The deep-pool reactor (DPR) is a heating reactor working under atmospheric pressure and moderate temperature for the requirements of seawater desalination. This reactor is distinctive from other nuclear power reactors, with key features including simplicity of structure, proven technology, small pow

In dealing with the fine carbon loaded wastewater from a TV picture tube plant, the technique of vibration membrane was proven to be a more effective means than the conventional coagulation and settlement method. The present work is to look into the characteristics of the carbon particle sizes and t

Calcium sulfate dihydrate scale was electrochemically deposited from supersaturated solutions on gold electrodes (probe) of an electrochemical quartz crystal microbalance (QCM). From measurements of the induction period for the gypsum nucleation, the interfacial tension was calculated. The dependenc

The availability of fresh water and energy is the key factor in the planning of many countries’ development, particularly those of large over-populated arid areas. Potable water supply shortage and recent technological development have led to wider application of conventional, and yet advanced salin

In the Arabian Gulf region, port and waterway authorities are becoming increasingly concerned about accelerated tidal and splash zone concentrated corrosion on marine tubular steel piles. The coating protection and maintenance of tubular steel pilings located in a marine environment can be difficult

Column-mode removal of boron from geothermal wastewaters of the Kizildere Geothermal Power Station, Denizli, was performed using Diaion CRB 02 N-glucamine-type chelating resins. The resin was tested for 10 sorptionwashing-elution-washing-regeneration-washing cycles in the geothermal field. The boron

The evaporation of a thin liquid film flowing down on the internal face of one plate of a vertical channel is studied. The wet plate is subjected to a uniform heat flux while the second plate is taken isothermal and impermeable. The governing equations in the liquid and in the gas regions with the b

This paper presents the characteristics of a solar desalination system based on the humidification–dehumidification principle. The system which, can be used in an open or closed cycle for air, is a modular one. It has the following independent components: two solar collectors, an evaporator and a co
