Aluminum Chemical Solutions for Wastewater Treatment - Water and Wastewater - Water Treatment
As a wastewater treatment solutions provider, USALCO® offers a complete aluminum portfolio to municipalities and companies to treat sewage and industrial waste. Much of wastewater produced today is contaminated with both soluble and insoluble impurities such as suspended solids, organics, pathogens, metals, nutrients and other priority pollutants that must be removed prior to discharge back into the environment. Federal, state, and local governments have created stringent environmental laws which define the acceptable levels of wastewater effluent quality. Those laws are administered and regulated by the issuance of discharge permits.
Compliance with Wastewater Treatment Requirements
USALCO products and onsite technical services help both municipalities and industry improve wastewater quality and compliance.
Chemicals used to remove specific wastewater contaminants, thereby enabling customers to meet their EPA mandated discharge permits, include:
Alum acts as a coagulant, precipitant and flocculant (settling agent) to aid in the removal of contaminants such as turbidity, BOD, TOC and color to name a few. Both alum and sodium aluminate are extremely effective in wastewater applications requiring phosphorus removal.
Typical Chemical Solutions
Products often purchased by wastewater treatment plants include:
- Alum or aluminum sulfate
- Sodium aluminate
- Polyaluminum Chloride
- Polymer (dewatering)
- Sodium hydroxide
- Ferric Chloride
- Ferrous Chloride
Results
USALCO’s extensive line of aluminum-based chemicals for wastewater treatment offer numerous benefits which include:
- Effective coagulation and solids settling

About the Clean Water Act
Amendments in 1972 to the Federal Water Pollution Control Act (Public Law 92-500–, known as the Clean Water Act (CWA), established the foundation for wastewater discharge control in this country. The CWA’s primary objective is to ‘restore and maintain the chemical, physical and biological integrity of the nation’s waters.’
Today, approximately 16,000 municipal wastewater treatment facilities are in operation nationwide. The CWA requires that municipal wastewater treatment plant discharges meet a minimum of “secondary treatment.”
Over 30 percent of modern wastewater treatment facilities produce cleaner discharges by providing even greater levels of treatment than secondary, according to the EPA.
