You can also find TFC"s products in water and waste water treatment plants, there are basicly five primary steps for water treatment

 

Disinfection

Chlorine is added to the water for disinfection

 

Coagulation and flocculation

Alum is added in proportion to the river turbidity to form floc particles created from the suspended materials in the water

 

Sedimentation

The water travels through sedimentation basins where the heavier material settles. Coagulation and flocculation remove turbidity as well as metals, including arsenic

 

Filtration

Following sedimentation, the water travels through an extensive filtration process that removes sediment and other suspended materials.

 

Corrosion control

At the end of the treatment process, PH is adjusted with caustic soda (NaOH) to reduce corrosion in plumbing systems.
