Aluminum Chemical Solutions for Potable Water Treatment - Water and Wastewater - Drinking Water

USALCO’s aluminum based coagulants have become the preferred choice of municipalities and industry for the treatment of potable (drinking) water and plant process water (such as pulp/paper and food/beverage). Water treatment processes typically employ the use of the following USALCO® products to effectively meet and/or exceed customer’s requirements for regulatory compliance.

USALCO has been a leading US manufacturer of aluminum based chemicals for over 60 years.  USALCO has a long history of developing close relationships with our customers to create innovative and flexible customer solutions.  These unique capabilities and services are what sets USALCO apart from other chemical manufacturers:

  • Assurance of Availability – Most of USALCO’s product lines are available from multiple plant sites to insure quality product is delivered in a timely manner.

Reduced Turbidity:  Achieved by separating suspended and settleable solids both organic and inorganic. USALCO coagulants provide excellent performance in applications where the turbidity levels fluctuate.  (Read more about the EPA and state turbidity requirements in National Primary Drinking Water Regulations

Reduced TOC (Total Organic Carbon) and DBP Precursor Control:  Enhance Stage 2 DBP rule compliance by reducing raw water TOC levels though enhanced coagulation to positively impact Disinfection By Product (DBP) generation. DBPs are produced when organic materials in the water react with disinfection chemicals used in water treatment, such as chlorine.

Reduced Sludge:USALCO’s aluminum-based coagulants, which contribute (on average) 60% less sludge than iron-based coagulants to significantly reduce processing and disposal costs.

Improved performance in ‘less-than-ideal’ treatment conditions: DelPAC is effective in very cold water treatment often with no change or little change in dosage.  DelPAC products work very well in applications where the PH levels fluctuate.

Reduced pre– or post-treatment pH adjustment:DelPAC products have less effect on pH.  This could translate into reduced purchases of caustic soda or lime for pH management, fewer chemicals to manage, less truck traffic.

Regulatory Approval: USALCO coagulantsmeet the specifications of the American Water Works Association Standard B403-98 and comply with the requirements of NSF and ANSI Standard 60: Drinking Water Treatment Chemicals-Health Effects.  To learn more and determine maximum dosage for a particular product, please visit the USALCO link on the NSF website.

USALCO offers consistent performance, value and economy when compared to proprietary coagulants on the market for potable and process water treatment.
