Understanding pH in Water Treatment

One of the primary categories of chemicals used in wastewater treatment is coagulants. Coagulants are substances that help remove suspended solids from wastewater by neutralizing the charge on these particles, allowing them to aggregate and settle out more easily. Common coagulants include aluminum sulfate (alum), ferric chloride, and polyaluminum chloride. These chemicals facilitate the process known as coagulation-flocculation, where small particles combine to form larger aggregates, or flocs, that can be removed from the water.


Sewage treatment plants often face challenges with foul odors, primarily due to hydrogen sulfide and ammonia emissions. Chemicals such as sodium hypochlorite and calcium nitrate can be used to mitigate these odors. Sodium hypochlorite reacts with hydrogen sulfide to neutralize its presence, while calcium nitrate inhibits the formation of odorous compounds.
