Description
Ferric Chloride, also known as Iron(III) Chloride, is a powerful inorganic coagulant commonly used in water and wastewater treatment. It is available in both solid (anhydrous flakes) and liquid forms. Upon dissolution, it hydrolyzes to form ferric hydroxide, which effectively removes suspended solids, phosphorus, heavy metals, and organic matter through coagulation and flocculation. It is also used as an oxidizing agent in industrial processes, and as an etchant in electronics manufacturing. Ferric Chloride is highly effective across a wide pH range and suitable for municipal, industrial, and commercial applications.
