Overview on the Separation and Removal of Haloaceticacid's in Drinking Water

摘要

The increase of pollution and the expansion of industrial, agricultural wastewater and urban runoff discharges in water sources have intensified the concentration of water pollutants. Considering that in Iran as in other countries the major part of drinking water is obtained from surface waters and due to the importance of disinfection, chlorination is doubtlessly the optimum and most common water treatment method used. However this method produces chlorination by-products (CBPs). Trihalomethanes (THMs) and Haloaceticacids (HAAs) are the main and most important groups of disinfection by-products (DBPs), Separation of THMs has gained a lot of breakthroughs since a lot of time elapses from its discovery. One of these breakthroughs is the separation of THMs with nanofiltration membranes, carried out by Koyuncu et al.(2007) in Technical University, Istanbul. They were able to reach the required standards (80-100 μg/l). This research will go through the historic and the studies made on the separation of HAAs.
