Abstract
|
Process
monitoring and automation can improve efficiencies in wastewater treatment
systems. Authors describe a number of parameters worth monitoring, and
provide tips for implementation.
There
is growing interest in automating wastewater treatment processes across a
broad range of industries. In particular, a paradigm shift is emerging in
automating industrial wastewater treatment in various sectors of the chemical
process industries (CPI). 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.
