Maintain regulatory compliance and eliminate measurement uncertainty using ABB turbidity and total suspended solids system.

Measurement made easy

ABB’s ATS430 turbidity and TSS system

Introduction The clarity of water in a stream, river or ocean is a photosynthesis, aquatic plants struggle to produce key determinant in fostering a healthy and balanced the oxygen needed for the survival of other aquatic aquatic ecosystem. The clearer the water, the life including fish, amphibians and waterborne greater the ability of light to penetrate to aquatic insects. plants which generate the oxygen needed for aquatic life. Within the wastewater treatment plant itself, excess

Controlling the level of turbidity and suspended treatment process. It is important to address this as solids in treated wastewater discharged to the residual suspended solids breaking through from environment is therefore vital in preventing damage sewage digestion processes will continue to have a caused by depletion of dissolved oxygen levels. For biological oxygen demand as they enter the this reason, turbidity and suspended solids receiving water. concentrations of effluent discharges in particular are tightly regulated and need to be carefully Controlling suspended solids is equally important in monitored to ensure that regulatory limits are industrial wastewater applications, where there is maintained. the added risk of toxic or metallic compounds
