Hardman ALPHOS is a polyaluminium chloride product specifically formulated for optimised precipitation of reactive phosphorus in effluent from sewage treatment plants and industrial wastewater processes.

In plants where ALPHOS has been adopted, phosphorus levels have been reduced to significantly lower levels than limits set by the EPA and other authorities. ALPHOS is not only cost effective, but also shows improved dose-response under critical plant loading conditions compared to using Aluminium Sulphate or ferric coagulants.
