Advantages Gained in Automating Industrial Wastewater Treatment Plants

By J.P. Pasterczyk, GE Water & Process Technologies |

Process monitoring and automation can improve efficiencies in wastewater treatment systems. A number of parameters well worth monitoring, as well as tips for implementation are described  There is growing interest in automating wastewater treatment processes across a broad range of industries. In particular, a paradigm shift is starting in automating industrial wastewater treatment in various sectors of the chemical process industries (CPI), such as foods (especially grain processing, sugars, sweeteners and edible oils), beverages (mainly soft drink bottlers and breweries), and hydrocarbon and chemical processing (particularly petroleum and petrochemical plants). The driving forces behind this evolution are economic. Wastewater process optimization most often leads to a more efficient use of chemicals, reduced energy consumption and less solid waste. Most wastewater-treatment systems use a common sequence of steps (Figure 1), with the purpose of first removing solids materials in the influent wastewater, recovering lost product, removing solids, fats, oils and greases (FAG), treating the water biologically and chemically enhancing flocculation, coagulation and physical removal of the biological solids and sludge. The clarified and…
