CHEMICAL DOSING UNIT (CDU)

The Chemical Dosing Unit (CDU) is a pH correction  system used to treat contaminated water with a high or low pH and high Total Titratable Acidity (TTA) levels. The CDU is also used primarily to treat water from Acid Sulphate Soil landscapes, but can also be used to treat ammonia, for disinfection and subsequent dechlorination of water mains, for clarification of lakes and other water bodies, for dispersal of pest-control measures in waterways, and more.
