For food processors, removing suspended solids such as fats, grease, grit, contaminants and leftover process materials from liquids is necessary to comply with regulations like the EPA’s Clean Water Act.
For years, a Spanish ice cream producer had been using aluminum-based coagulants and caustic soda to control pH during the dissolved air flotation stage of wastewater treatment. It worked well enough but was unstable and challenging.
Automated wastewater treatment systems can help food processors remain in compliance with EPA and local standards, while significantly reducing the cost of treatment, labor and disposal.
