A newly synthesized azo compound, namely 8-quinolinol-5-azoantipyrine (HQAP), was studied as an inhibitor for the corrosion of mild steel in 1M HCl. Results of weight loss and Tafel polarisation measurements show that this compound has fairly good inhibiting properties for steel corrosion in acidic

Natural zeolites are good potential material for water and wastewater treatment. It is due to the advantages of low cost, ion-exchange and adsorption capability of the natural zeolites. It can also be modified and regenerated. This paper thus looks at efforts made in exploring the potential applicat

A novel stainless steel membrane module with a 0.2 µm nominal pore diameter was applied in an aerated submerged membrane bioreactor to treat synthetic domestic sewage. The pore size of metal membrane was more homogeneous and of tighter distribution than that of organic membrane. The steady membrane

Separation of ions from aqueous solutions was performed by reverse osmosis (RO) on an "-alumina-supported MFI-type zeolite membrane synthesized by in-situ crystallization. For the 0.1 M chloride single-salt solutions, the separation efficiency in terms of ion rejection was found to increase with the

The potential of direct membrane filtration on either ultrafiltration (30, 200 and 400 kDa MWCO) or nanofiltration (200 Da MWCO) membranes was studied as a method of treatment of low load graywater for on site reuse. The graywater collected from a sports center’s public showers and characterized for

This work presents a computer program developed for sizing and simulating a solar-powered desalination station using the SMCEC principle. This is motivated by the absence of such software in this area. The computer package includes mathematical models for different compartments of the desalination u

In the food and beverage industries, spent process water streams containing very different levels of contamination are combined and routed to the mixing and equalizing tank where problems in biological wastewater treatment occur. It could be shown that the treatment of the partial streams for differ

Molecular imprinting of polymers, a cross-linking polymerization of functional monomers in presence of a template, yields synthetic materials mimicking the function of biological receptors [1]. The controlled photoinitiated synthesis of thin layers of molecularly imprinted polymers (MIPs) [2] offers

The dynamic modelling and simulation of the three sections of a water desalination facility using the Solar Multiple Condensation Evaporation Cycle (SMCEC) technique are presented. The models are obtained using thermal energy and mass balances of the different sections of the unit. The resulting dis
