Ferric Sulphate (Fe2(SO4)3) is a naturally occurring salt of iron. Ferric is used in a range of water-treatment applications either alone or in conjunction with other chemicals.

 How does it Work?

When ferric is added to dirty water the charged molecule causes ionic attraction between suspended solid particulate. This leads to an increase in particulate size or “Coagulation”. Coagulation is an important process in water treatment as many contaminants are too fine to settle under their own weight alone. Coagulation also has the effect of increasing the reaction surface of contaminants leading to better flocculation when polymers are used in conjunction.

Advantages of Use Ferric Sulphate

Used in water treatment will increase coagulation, and give a strong pH shift. Because of the strong coagulation & pH shift abilities, very low amounts are needed to achieve the desired effect as well as making it ideal for neutralizing alkaline waters. Ferric Sulphate is considered DG under Australian Chemical Regulations.
