Set to determine the chlorine content in drinking water, of the type consisting of a container in which two bottles are placed, one containing the reactive liquid, and the other containing the sample of drinking water, characterized in that said assembly comprises a scale of graduated color and...
Small Water SystemsKansasA problem with trihalomethane (THM) levels in its finished water required the Crawford Country Rural Water District Number 6 (CCRWD), Parsons, Kansas, to investigate methods of oxidizing THM precursors. Testing indicated that chlorine dioxide is a viable alternative for ...
Groundwater, or surface water of the same quality as groundwater, has always been the preferred source of potable water In the Federal Republic of Germany. Outlined are analytical techniques to detect chlorinated organics and the effects of chlorine and ozone treatments on water quality in that ...
Taste and odour problems in potable water Esther Ortenberg, Benjamin Telsch, in Handbook of Water and Wastewater Microbiology, 2003 3.2.2 Oxidants and their by-products The following are the main oxidants used when treating potable water: 1. Chlorine (Cl2) 2. Chlorine dioxide (ClO2) 3. Chlor...
Chlorine Dioxide-a Development in Treatment of Potable Water. Chlorine dioxide ClO2, is a powerful oxidizing gas which, owing to its instability, cannot be stored in bulk but must be used on the spot where it is neede... JF Synan,J. Macmahon,GP Vincent - 《Water Works & Sewerage》 被...
Continuous recording of residual chlorine is not a new idea. Rather this has been the aim of scientists and operating personnel since chlorination of potable water was first placed on a continuous basis in 1908. Actually the development ... A Griffin 被引量: 2发表: 1953年 加载更多来源...
But the beneficial consequences of chlorine applications have sustained high rates of use in food-processing plants worldwide. Chlorine is the most commonly used means of disinfecting potable water, usually at about 1–2 p.p.m. However, in-plant chlorination in the food industry is often used ...
According to the German Ordinance on Potable Water5, the free chlorine content in drinking water should be even adjusted between 0.1 and 0.3 ppm after the disinfection process. The most common chromophores for photometric and visual detection of free chlorine are N,N-diethyl-p-phenylene-diamine (...
Chlorination of potable water supplies high in organics may yield carcinogenic substances such as trihalomethanes. ClO2 has been proposed as an alternative disinfectant to chlorine. However, it is a strong oxidant that forms considerable amounts of chlorite when mixed with potable water supplies, and...
Premise plumbingFungi are near-ubiquitous in potable water distribution systems, but the disinfection kinetics of commonly identified fungi are poorly studied. ... X Ma,K Bibby - 《Water Research》 被引量: 7发表: 2017年 Role of drinking water biofilms on residual chlorine decay and trihalomethan...
