INTERNATIONAL REPORT WATER AND WASTEWATER DISINFECTION
wastewater, disinfection practices, and issues and developments in specific countries. Additionally, selected similarities and differences between water and wastewater disinfection practices will be discussed. The information presented is based, in part, on the national reports on disinfection of water and wastewater that were submitted by 22
Chlorine for Wastewater Treatment. The use of chlorine for water treatment has a long history since its first use in Jersey City in 1908. Despite the use of chlorine globally to produce safe drinking water, chlorination is not a simple process, especially considering that chlorine itself is toxic.
Wastewater Technology Fact Sheet: Chlorine Disinfection
Wastewater Technology Fact Sheet: Chlorine Disinfection Author: US EPA, OW, OWM, Water Permits Division Subject: Fact sheet on disinfection, one of the primary mechanisms for the inactivation or destruction of pathogenic organisms. Contains information on how to use chlorine as a disinfectant for municipal wastewater.
Today, UV disinfection is widely accepted for municipal wastewater disinfection around the world. UV is rapidly growing, given it’s a safe and cost-effective alternative over chemical disinfection. Also, it produces no disinfection byproducts or a chlorine residual, which is harmful to the environment.
Chlorination of Indicator Bacteria and Viruses in Primary
Wastewater disinfection is used in many countries for reducing fecal coliform levels in effluents. Disinfection is therefore frequently used to improve recreational bathing waters which do not comply with microbiological standards. chlorine is still a widely used chemical disinfectant for the treatment of wastewater discharges. In the
Disinfection is the process of destroying pathogenic micro-organisms by physical means. This bulletin is directed toward chlorine, the most widely used chemical for disinfection, and sulfur dioxide for dechlorination. Proper disinfection ensures removal of pathogens from wastewater before it is discharged to the environment. The
Chlorine dioxide as a disinfectant - Water Treatment
At the concentrations required for disinfection, chlorine dioxide is not corrosive. Chlorine dioxide is more water-soluble than chlorine. In the last few years better and safer methods for chlorine dioxide production have been developed. Figure 3: the influence of pH on efficiency is larger for chlorine than for chlorine dioxide

Improving Chlorine Measurement Accuracy in Malaysia
Chlorine continues to be a popular water disinfection treatment method because of its relatively low-cost and availability around the world. There have been many methods developed to measure chlorine and thereby determine correct dosing concentrations, which includes the standard DPD (N, N Diethyl-1, 4 Phenylenediamine Sulfate), colorimetric
