PolyAluminium Chloride (PAC): Effective technology for water purification De Dietrich^® offers a complete range of advanced and dedicated solutions for PAC Producers South East Asia

Polyaluminium Chloride, usually called PAC, is a fast growing coagulant used in water treatment. PAC is highly-efficient for the treatment of drinking water, swimming pool water, sewage and industrial effluents, as well as for paper processing. PAC offers numerous advantages in comparison to other mineral coagulants, including lower dosage requirement, less flocculent needed, reduction of sludge and sulfate concentration, effective at low temperatures, and a wide range of PH.

De Dietrich^®, leveraging decades of experience as a leader in the water treatment industry, offers a wide range of solutions to PAC manufacturers. They produce all critical components related PAC and are not simply a manufacturer but also an engineering firm that has extensive knowledge on all aspects of this complicated process.

The firm provides turn-key units which have been optimized to reduce maintenance and operation expenses and improve safety and productivity. In addition, De Dietrich offers a complete range of advanced and dedicated solutions for the Polyaluminium Chloride synthesis and its derivatives for different PAC productions: PAC 14%, PAC 18%, PACS 10%.

Depending on the market requirement units can be sized from minimum 2,000kT per year to up to 50,000 kT per year. If needed, the units can also be designed so aluminum sulfate can be produced so as to cover a wider range of coagulants.

Die Dietrich offers a comprehensive service and product portfolio. They can offer basic and detailed engineering, supervision and assistance throughout all steps of the manufacturing process, and can procure glass-lined reactors, equipment, process control and automation, and valves and instrumentation. In addition they provide process optimisation through the use of the adapted Impeller Agitator and the D.e.Co.S. System

The return on investment of such units is around 2 years. The investment is particularly interesting when serving an area where PAC is not yet available or only transported from far away in solid form (Liquid PAC is significantly more efficient and easy to use for water treatment than solid PAC). With the expansion into the Southeast Asian Market, De Dietrich is the optimal solution for PAC manufacturers since all units can produced locally and do not need to imported from China or India.
