DelPAC (Polyaluminum Chloride Solution)

USALCO’s Polyaluminum Chlorides (PACL) fall under the trade name DelPAC®.  These coagulants have become the products of choice in well over 1,000 water treatment applications throughout the US (sold direct or through distributors).  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 DelPAC Series

USALCO manufactures a variety of Polyaluminum Chlorides to meet a wide range of water quality objectives.  The DelPAC series includes DelPAC 2020, which quickly gained wide acceptance as a cost effective product.   The use of DelPAC 2020 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.  DelPAC products are of high quality and meet the specifications of the American Water Works Association Standard B408-10 and complies with the requirements of ANSI/NSF 60 at a maximum dosage of 250 mg/L.

USALCO’s research and development staff is committed to continually developing new PACL technologies to address the ever changing regulatory landscape. Coupled with our on site application expertise, USALCO is uniquely positioned to meet the increasing customer demand for improved treatment results at a lower total cost.
