Modelling and control of potable water chlorination.
The Umgeni Water Wiggins water treatment plant feeds the southern areas of Durban in South Africa and has a maximum treatment capacity of about 350 Ml/d. Two interconnected reservoirs at this facility hold treated water before it enters the distribution network. Because of the variable demand, the reservoir levels and residence times undergo considerable variation. This has a strong influence o...
متن کاملModelling of Micropollutant Removal by Ozonation and Chlorination in Potable Water Treatment
In regards of increasingly stringent rules on toxicity, prediction engines for potable water treatment have become a necessity. This particularly applies to oxidation steps, where micropollutants should be removed and where potentially harmful by-products may be formed, and has therefore lead to the building up of a new simulator for both chlorination and ozonation. This first report aims at gi...
متن کاملModeling Micropollutant Removal by Ozonation and Chlorination in Potable Water Treatment
Having set general frames for our study [Mandel, 2007] and our software, SimOx, [Mandel et al., 2008] in previous publications, this report aims at giving a brief overview of the experimental part of the research done in 2008. The experiments were divided in two periods: from January to June and from October to the end of the year. During the first period, results were collected to validate a p...
متن کاملThe Chlorination of Water
Chlorine is most readily available in the form of chloride of lime (bleaching powder), which can readily be obtained commercially. This, if freshly made, should contain 33 per cent, of free or active chlorine. It loses its efficacy on keeping, especially during hot weather; but this loss may be retarded by the addition of 25 per cent, of quicklime. Samples of the bleaching powder used should be...
متن کاملSolving the Salinity Control Problem in a Potable Water System
Salinity is the relative concentration of salts in water. In a city of southern China, the local water supply company pumps water from a nearby river for potable use. During the winter dry season, the intrusion of sea water raises the salinity of the river to a high level and affects approximately the daily life of 450,000 residents of the city. This paper reports the application of constraint ...
