Water Treatment Plant Process- Chlorination or Ultraviolet Radiation By Shreya Shah Surface waters necessitate water treatment before consumption to guarantee no health risk is present to the user. Poor quality water which consists of dissolved and suspended particles‚ can impact and cause health risks to consumers. The most important contamination is the microbiological contamination as it leads to infectious diseases (Water Treatment‚ 1994). Chemicals such as nitrates and cyanide when contaminate

against short periods of drought or to allow water supply to be maintained during transitory pollution incidents in the source river. 4. Pre-conditioning – Water rich in hardness salts is treated with soda-ash (sodium carbonate) to precipitate calcium carbonate out utilising the common-ion effect. 5. Pre-chlorination – In many plants the incoming water was chlorinated to minimise the growth of fouling organisms on the pipe-work and tanks. Because of the potential adverse quality effects (see

Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed for a variety of other purposes‚ including meeting the requirements of medical‚ pharmacological‚ chemical and industrial applications. In general the methods used include physical processes such
