The activated sludge concentration refers to the content of suspended solids in the mixed liquor at the outlet of the aeration tank. It is expressed in MLSS, with the unit of mg/L, and is used to measure the amount of activated sludge in the aeration tank. Sludge concentration is one of the important indicators to measure the effect of sewage treatment, and it is also an important parameter to evaluate the operation of sewage treatment facilities. The online sludge concentration sensor MLSS3 series developed and produced by Daruifuno is based in the principle of optical scattering. The sensor emits a beam of light and irradiates the light into the sludge sample. The particles in the sludge scatter the light to form scattered light. The built-in optical sensor of the sludge concentration receives the scattered light and measures the intensity and angle of the scattered light to calculate the concentration of particles in the sludge. This online optical sludge concentration sensor is suitable for measuring various types of sludge, including suspended particles, organisms and chemicals. It is widely used in sewage treatment plants, chemical plants and pharmaceutical plants to monitor the concentration and quality of sludge.

Delfino focuses on the research and development and production of water quality instruments. Our main products include pH ORP analyzer, conductivity analyzer, turbidity analyzer, COD analyzer, dissolved oxygen analyzer, ammonium analyzer, chlorine analyzer, etc. If you are interested in our products, please contact us! In sewage treatment plants, using online sludge concentration sensors to monitor sludge concentration can help staff adjust the treatment process in time to ensure treatment results. If the sludge concentration is too high or too low, it will affect the treatment effect. Too high sludge concentration will cause the treatment equipment to be blocked and affect the treatment efficiency. Too low sludge concentration will lead to poor treatment results and the pollutants cannot be completely removed. Therefore, monitoring sludge concentration can help staff adjust the treatment process in time to ensure the sewage treatment effect.?
