Disinfection by-products

Disinfection is an essential step in a water treatment process. Depending on the method and water quality, different by-products are generated which could affect the final water quality.

Water treatment to remove microorganisms is very important especially when water comes from lakes and rivers, etc. These water sources may contain high levels of pathogens as a result of inadequately treated sewage discharges or storm water run-off.

Generation of by-products
During the disinfection process different by-products are generated as a result of the reaction with compounds in the treated water or from the disinfectant itself.
Limit values
Limit values have to be observed at all times. Limit values for most by-products are available in regulations, guidelines and standards which are often specific for different countries or applications.
