Municipal Sewage Treatment Chemicals

Our products can be used in all solid-liquid separation processes in municipal (or sewage) wastewater treatment. Examples are as follows: Primary sewage treatment, physic-chemical method. Often the use of an anionic polymer in combination with an inorganic/organic coagulant can reduce the biological loading on the secondary treatment. Additionally by accelerating settlement rates in the primary clarifiers the size of the clarifier can be reduced, resulting in a significant capital saving.

 

Activated sludge treatment, biochemical process. Product choice is entirely depend on the application although typically a medium to high charge cationic polymer is required.

 

Digested sludge treatment. Typically higher charged cationic polymers are more effective with the choice of molecular weight being dependant on the solid-liquid separation process.
