Ferric Chloride Liquid is a solution of Iron III Chloride (FeCl3) in water. It is manufactured by virgin raw material in an oxidation process using chlorine and Ferrous Chloride solution.

Ferric Chloride Solution is a concentrated solution ranging from 30-45% Ferric Chloride.

Typical Applications and Benefits:
Ferric Chloride Solution is an excellent source of Fe3+ ions where the application demands a strong inorganic cationic metal salt. The applications where Ferric Chloride Solution is often the product of choice are:

Municipal and Industrial Wastewater Treatment
- Hydrogen Sulfide (H2S) gas and odor reduction
- TSS (Total Suspended Solids) removal
- Phosphorous removal
- COD (Chemical Oxygen Demand) reduction
- BOD (Biological Oxygen Demand) and TOC (Total Organic Carbon) removal
- Sludge dewatering

Municipal and Industrial Water Treatment
- Color removal
- Turbidity removal
- TOC (Total Organic Carbon) reduction

Printed Circuit Boards
- Copper etchant
