ALUMINIUM CHLOROHYDRATE (ACH) PRODUCTION PLANTS

Aluminium chlorohydrate, commonly known as ACH, is an inorganic coagulant derived from aluminium chloride. Its chemical formula is Aln(OH)mCl(3n-m).H2O, where n varies depending on the degree of basicity of the product. This element occurs in liquid form. Its main function in water treatment is the coagulation and flocculation of suspended particles.

KERN S&D plants respond to a worldwide need, which is the on-site industrial production of small volumes of Chlorine and chlorinated products such as Aluminium Chlorohydrate.

KERN SD has innovative technologies for the production of ACH, based on different process routes that allow the use of aluminium, in the form of granules or ingots, hydrochloric acid (HCl), aluminium chloride (AlCl₃), or PAC, depending on the available raw materials and the required product specifications. The reaction is carried out in batch, in reactors manufactured from high chemical-resistance materials, such as glass-lined steel or high-grade glass-reinforced plastic (FRP). Once the reaction is completed, the product is discharged and filtered to remove unreacted aluminium/alumina and other insoluble materials, and finally, the clarified product is transferred to storage tanks.

KERN S&D use safe, environmentally friendly and highly competitive technology due to their low investment and low operating costs (high electrical efficiency and degree of automation). KERN S&D’s technology complies with the Community Directives on Best Available Technologies (BAT) for chlor-alkali production (Directive 2010/75/EU).
