Platinum and other platinum metals have been widely applied in industry. The recovery of noble metals from industrial wastes becomes an economic issue. The laboratory studies of removal of platinum (IV) microquantities from 0.1–6M hydrochloric acid solutions on the ion-exchangers of the functional q

Gas-filled membrane absorption has been used to remove cyanide from different cyanide containing wastewaters. In this study, cyanide removal from an industrial praziquantel wastewater has been investigated. The wastewater contained a high cyanide concentration and turbidity due to the presence of li

Sorption, diffusion and permeation of halogenated liquids such as chloroform, dichloromethane, carbon tetrachloride, 1,2-dichloroethane, 1,1,2,2-tetrachloroethane, trichloroethylene and tetrachloroethylene into commercial fluoroelastomer (FC-2177 D) were studied at 30, 40 and 50EC using the sorption

Modelling played an important role in simulation, optimisation, and control of multi-stage flash (MSF) desalination processes. Top brine temperature (TBT) is one of the many important parameters that affect optimal design and operation of MSF processes. Within the MSF process model, calculation of T

Membrane scaling is caused by the deposition of unsoluble salts as feedwater converted to brine, affectting the operation of seawater RO plants. Membrane scaling at the Dalian RO desalination plant was analyzed using Dalian seawater. Based on the characteristics of Dalian seawater, a new environment

The reuse of wastewater from the dairy industry was investigated using coagulation, adsorption and membrane separation. Dairy industry was chosen as it requires huge volume of water. In recent times, development of newer membranes with high flux/rejection characteristics have increased the probabili

During the past few years, Kuwait has been encouraging the development of alternative water resources. This stems from the fact that the available natural water resources are scarce, and water demands are growing due to increasing population growth. A potential alternative water resource which may r

A discontinuous tank reactor was used to eliminate 4-chlorophenol using soybean peroxidase (SBP) and hydrogen peroxide in an attempt to reduce the concentrations of buffer solutions used and to avoid adding polyethylene glycol. The stirred-tank reactor was operated in different operating conditions,

Crude oil released to the marine environment through accidental spillage or drainage from land causes serious damage to the environment and marine life. Treatment of oil spills remains a challenge to environmental scientists and technologists. Sorption is a popular technique applied for treatment of

Although pre-treatment of membranes is often used to ensure the reliability of experimental data, it also has the potential to improve many aspects of membrane performance. This study investigates the influence of chemical pre-treatment and wetting on membrane flux and retention. The results show th
