Drinking water

A survey study on radioactivity in drinking water from three lakes in the region of Attika in Greece is in progress since 2004. The measurement of gross alpha and gross beta activity is used as a screening method. All the values of alpha and beta activity in the selected water samples were lower tha

One of the most important tasks at any water treatment plant is safeguarding the quality of drinking water. Worldwide, the drinking-water sector is increasingly aware of the limitations of end-product testing for ensuring safety. One limitation is the steady increase in the number of potentially occ

In this study, aluminium sulphate (alum) and polyaluminum chloride (PAC) coagulation were used for coagulation of different origin water (Buyukcekmece, BC and Omerli, OM in Istanbul, Turkey and Carmine, CR in Salerno, Italy) treatment. The effect of pre-ozonation alone and combined with coagulation

Occurrence of organic micropollutants in surface water, and thus potential drinking water supplies, raises concerns about the safety of the drinking water. Nanofiltration has been proposed as a potential technology to remove micropollutants. The removal efficiency with nanofiltration depends on the

Disinfection is a key treatment process for producing drinking water. However, it produces undesirable byproducts that may cause adverse health effects. Disinfection by-products (DBP) such as trihalomethanes (THMs) and haloacetic acids (HAAs) are considered potentially carcinogenic and have been rec

EU Directive 98/83, which aims at achieving beneficial effects in the quality of water and in public health, has set standards for water intended for human consumption, monitoring requirements of the new standards, and strategies to take remedial action to address failures. The incorporation of the

The occurrence of disinfection by-products (DBPs) in drinking water has been an issue of major concern during the last years due to their adverse health effects. The development and optimization of analytical methods for the determination of DBPs in water are key points in order to estimate human ex

An investigation into the occurrence of disinfection by-products (DBPs) was conducted for a period of two years (2001–2002) on the drinking water of Athens, Greece. Samples from four water treatment plants (WTPs) and from the distribution system of Athens were collected monthly and analyzed for DBPs

Among the European Union Directives enacted on water management and environmental protection, Directive 98/83/EC defines the mandatory quality standards for water intended for human consumption in order to protect human health. The implementation of this Directive has often encountered delays due to

The removal of arsenic from synthetic waters and surface water by nanofiltration (NF) membrane was investigated. In synthetic solutions, arsenic rejection experiments included variation of arsenic retentate concentration, transmembrane pressure, crossflow velocity and temperature. Arsenic rejection
