When water plants treat water sources, they often need to add some chemicals to purify and disinfect the water quality to ensure that the water supplied to residents meets hygiene and safety standards. The following are some common dosing agents used in waterworks:
Water purifier: used to remove turbidity, suspended solids, and colors from water, such as polyaluminum chloride coagulants, polyaluminum silicate, etc.
Disinfectant: Used to eliminate bacteria, viruses, and other microorganisms in water, the most commonly used disinfectant is chloride, such as chlorine gas, sodium hypochlorite, or chlorine containing disinfectants.
PH regulator: used to adjust the acidity and alkalinity of water to control its corrosiveness and stability, such as lime, caustic soda, etc.
Corrosion inhibitor: Used to control metal corrosion and pipeline corrosion in water, such as polyphosphate corrosion inhibitors.
Bacteriostat: used to inhibit the growth of microorganisms, prevent pipeline fouling and bacterial growth, such as polyammonium chloride.
It should be noted that different regions and waterworks may choose different reagents for dosing based on the actual situation. The use and dosage of these drugs need to be strictly implemented in accordance with relevant laws, regulations, and hygiene standards to ensure the safety and compliance of water quality. At the same time, the water plant will also regularly test and monitor water quality to ensure that the water supply meets hygiene requirements.
