USALCO delivers Alum and Sodium Aluminate to municipalities and companies to treat sewage and industrial waste. We supply the product in bulk quantities in dedicated transportation equipment to insure quality. USALCO has multiple plants. USALCO offers free jar testing and trials to optimize chemical dosages and to help your plant stay in compliance.
The 1972 Amendments 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.’
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 the wastewater treatment facilities today produce cleaner discharges by providing even greater levels of treatment than secondary, according to the EPA.
Much of the wastewater produced 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.
USALCO products and onsite technical services help both municipalities and industry improve wastewater quality and compliance. Aluminum sulfate (alum), acidified aluminum sulfate (acid alum), and liquid sodium aluminate all serve to remove specific wastewater contaminants, thereby enabling customers to meet their EPA mandated discharge permits.
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.
Some of the benefits of USALCO wastewater treatment with sodium aluminate and/or alum are as follows:
- Effective coagulation and solids settling
- Optimal phosphorus removal at lowest dosage
- Improve ammonia removal in alkalinity deficient wastewaters
- Optimizes UV disinfection
- Enables PH control and compliance without additional chemicals
- Algae control and prevention in lake water remediation
Products often purchased by wastewater treatment plants include:
- Alum or aluminum sulfate
