Coagulation water treatment process | Hard and Soft Water
It is a vital part for drinking water and wastewater treatment. Coagulants. Coagulants are the chemicals that are used to removes tiny particles in water. We used different types of coagulants in coagulation water treatment process. Generally, we can categories the common type of coagulant into two groups, aluminium base and iron base.

Treatment of textile effluents by using natural coagulants
In potable water treatment, clarification of water using coagulating agents has been practiced from ancient times. As early as 2000 BCE the Egyptians used almonds smeared around vessels to clarify river water. The use of alum as a coagulant by the Romans was mentioned in around 77 AD.

Optimization and economic evaluation of modified coagulation
In order to prepare a 10 percent clear solution for coagulant, 10 g of PAC was dissolved to 100 mL of distilled water (EC = 0.1 µs/cm). In order to prepare a 0.1 percent solution as coagulant aid, 0.1 g of each polymer was provided separately.

APPLICATION: DRINKING WATER DISINFECTION Application Note
The source water is a river water stored in a large reservoir (artificial freshwater sea), the intake location is ~10 miles away of the plant. The plant adds ammonia to the raw water at the intake, followed by free chlorine (~30 sec after ammonia injection), and prior to addition of coagulant (alum) downstream on site. The

Coagulation-Flocculation In Leachate Treatment Using
Results showed that the PAC was effective in leachate treatment. The used of synthetic polymer proved to be effective as coagulant aids for lechate treatment. The used of 2000 mg/L coagulant (PAC) with different of doses of polymers caused an increase in suspended solid (SS), COD, color, and ammoniacal nitrogen (NH 3 N) removal efficiency. A
