Polyaluminum Chloride has become the coagulant of choice in many water treatment applications. USALCO manufactures a wide variety of Polyaluminum Chlorides to meet a wide range of water quality objectives. USALCO has manufactured chemicals for over 60 years, and began full scale production of the patented process (US Patents 5,985,234; 5,997,838; 6,036,935 and Canadian Patent 2229266) for manufacturing Polyaluminum Chloride in 1996. USALCO’s Polyaluminum Chlorides fall under the trade name DelPAC.
USALCO’s DelPAC Series
The DelPAC series includes DelPAC 2020 which has quickly gained wide acceptance as a cost effective product which often improves finished water quality when compared to other coagulants, including all other Polyaluminum Chlorides commercially available.
DelPAC 2020, when used as a coagulant, can provide longer filter runs, reduce or eliminate the need of alkali for pH adjustment, lower amounts of residuals and generally has the lowest overall costs of any treatment program.
USALCO also provides on-site technical support.
