Effective COD Removal in Tannery Wastewater Treatment

Product Description:

Poly aluminum chloride, also known as PAC, is a prominent water purifying and coagulating agent. This water-soluble inorganic polymer is formed by combining ALCL3 and AL (OH) 3. Its chemical formula is [AL2 (OH) NCL6 NLm], where m indicates the degree of polymerization and n represents the degree of neutrality of the PAC product.

PAC can be identified by its yellow or light yellow, dark brown, or dark gray resin-like solid appearance. Its remarkable bridging adsorption capabilities enable physical and chemical processes, including coagulation, adsorption, and precipitation, to occur during the hydrolysis process. The primary difference between PAC and traditional inorganic coagulants is that traditional coagulants consist of low molecular crystalline salts, while PAC comprises a structure of diverse multi-carboxyl complexes. With a rapid flocculation and precipitation rate, a wide applicable range of pH values, no corrosiveness to pipeline equipment, and a notable water purification effect, PAC is highly effective.

One of the most significant benefits of PAC is its ability to successfully remove various heavy metal ions, such as SS, COD, BOD, arsenic, and mercury, from water. Due to this, PAC is extensively used in drinking water, industrial water, and sewage treatment fields. Its unparalleled performance makes it a sought-after water treatment solution in various industries.
