Drinking water

Water from Lake Butoniga near the town of Buzet, Croatia, was used as a source for drinking water production. Since lake water has a high concentration of trihalomethane precursors, a treatment was necessary. A process including ozonation, flocculation and filtration was chosen on the basis of preli

It is now common knowledge that membrane filtration processes can be considered as high performance separation techniques, not only in laboratory experiments but also in many industrial applications. With its strong development for the production of large-scale drinking water, the ultrafiltration on

The importance of wastewater treatment in the food industry is growing nowadays, because of the rising cost of water and because of environmental pollution. The aim of this study was to decrease the chemical oxygen demand (COD) of two different wastewaters originated from the food industry. If the t

Since the early 1980s, microfiltration and ultrafiltration have been widely used for drinking water applications. More recently, membranes have started to be used in membrane bioreactors or on secondary wastewater effluents for reuse application. Until recently, in desalination treatment plants seaw

Controlling fouling of membrane filtration installations (nanofiltration and reverse osmosis) is a major challenge for the water industry. Fouling affects the plant performance and increases the costs of plant operation. Diagnosis of the type(s) and extent of fouling is the essential first step for

This study is focused on the influence of the nature of the water to be treated on the efficiency of nitrate elimination by a commercial membrane. By gradually increasing the complexity of the treated solutions (binary, ternary mixtures and then natural waters), we identified the physical, chemical

Electrodialysis (ED) is an efficient process for the treatment of drinking water with high nitrate concentration. However it achieves only a transfer of pollution by producing concentrated brines. This study demonstrated the feasibility of ED brine denitrification in a membrane bioreactor (MBR). The

The removal of low molecular mass charged compounds from water streams in an ion exchange membrane bioreactor (IEMB) was studied. This integrated membrane process combines continuous ion exchange transport (Donnan dialysis) of the pollutant through a non-porous membrane, selective for the transport

In this study the removal of humic substances from model-solution and well-water using four different ultrafiltration membranes has been investigated. The permeates were analysed by UV254nm absorbance, TOC and DOC measurements. Based on our experiments it can be established that the examined membran

Arsenic removal from drinking water is a major problem in many parts of the world. We have investigated arsenic removal by flocculation and microfiltration. Ferric chloride and ferric sulphate have been used as flocculants. The use of small amounts of cationic polymeric flocculants, as flocculation
