Ferric sulfate solution is widely used in water treatment processes as a coagulant to remove impurities and suspended solids. It effectively binds with particles, forming larger flocs that can be easily separated from the water. This makes it valuable in treating both drinking water and wastewater, ensuring clarity and reducing contaminants. In industrial settings, it is employed for sludge conditioning, improving the dewatering process and reducing the volume of waste. Additionally, it is used in the textile industry for dye fixation and in the production of pigments and other iron-based compounds. Its ability to neutralize odors and control phosphates also makes it useful in environmental remediation projects.
