  • Analyzing Water Quality Parameters When Choosing AOP Systems For Water Treatment
    Analyzing Water Quality Parameters When Choosing AOP Systems For Water Treatment

    In water and wastewater treatment, chemistry is king. Treatment options are evaluated depending on the quality of water to be treated and the treatment application. Treatment systems including AOP systems, are designed to specifically target certain contaminants and remove or reduce them from the water. This takes places through the power of chemical reactions. Even biological treatments involve chemistry at their core.
