Mixed Liquor Suspended Solids (MLSS) is the concentration of suspended solids in an aeration tank during the activated sludge process, which is a key parameter to monitor the active biomass.
Detecting polymer levels helps safeguarding membranes, control overdosing or underdosing in sludge settling and dewatering, and minimizing operational costs or environmental impacts.
Total Suspended Solids (TSS) is the portion of not dissolved solid particles suspended in water. This includes organic and inorganic materials, such as silt, decaying matter, industrial wastes, and sewage.
Sludge Concentration (Solids concentration in sludge)
The Olpas Sludge Concentration sensors offers a cost-effective measurement with maintenance intervals that are four times longer compared to optical sensors.
Dry Solids measurement for Dry Cake, measuring sludge cake density in concentrations from 10 - 40 %DS. There are inline sensors available, and sensors with a sample-grabbing device.
Measuring Total Suspended Solids (TSS) in dewatering centrate is a challenging task, but the innovative OLPAS ultrasound measurement technology makes it achievable, providing valuable insights into the dewatering process's effectiveness.
Monitoring residual polymers in centrate is crucial for optimizing the dewatering process. The Olpas sensor provides a reliable measurement of this hard-to-measure parameter, even in dewatering centrate.
Polymers are aded during the watertreatment process to enhance the removal of suspended solids and other contaminants. Olpas sensors help monitoring polymer-concentrations during the process and even in effluent.
Available for inline measurement (with the sensor in direct contact with the fluid or paste) and as a clamp-on (for measurement through the pipe). For high solids concentrations up to 60 %DS.
RAS indicates the portion of settled activated sludge that is returned from the clarifier to the aeration tank. Maintains a high concentration of microorganisms for effective biological treatment.
