Primary Treatment
Primary wastewater treatment systems include different types of physical-chemical treatment equipment depending on the components in the wastewater. Often, industrial wastewater contains toxic or hazardous amounts of chemicals, resulting from the industrial process; some chemicals may be suspended, while others are dissolved in this wastewater. Additionally, physical-chemical treatment removes suspended and dissolved particles contained in wastewater.
We understand that effective primary wastewater treatment is critical to your plant operations, whether you are discharging directly to a POTW or treating prior to your biological wastewater treatment system. Nalco can provide creative solutions to optimize the performance of treatment chemicals and equipment that can dramatically minimize costs, maximize your return on investment, and significantly enhance your bottom line results.
