Online MLSS Sludge Concentration Sensor Sedimentation tank

The sedimentation method is the most basic way in sewage treatment. It is a process that uses the desity difference between suspended particles in water and water to cause sinking under the action of gravity to achieve solid-liquid separation. The grit tank in the sedimentation process is often used as a pretreatment method to remove inorganic particles that are easy to settle in the water. The grit chamber is a pretreatment unit that uses physical methods to separate sand particles from water. Its function is to separate particulate matter from water with a relative density greater than 1.5 and a particulate size of 0.2mm or more, which mainly includes inorganic sand, gravel and a small amount of dense organic particles such as core skins, seeds, etc. Grift chambers are generally set up before lifting equipment and treatment equipment to protect water pumps and pipes from wear, prevent subsequent blockade of water structures and reduction of the volume of sludge treatment structures, and at the same time reduce the inorganic content of activated sludge and improve activity of activated sludge. The MLSS300 series Sludge Concentration Sensor developed and produced by Daruifuno is specially designed for sewage and wastewater treatment. It uses infrared scattering method to monitor the value of sludge concentration in water in real time. Currently we provide three measuring ranges: 0~20g/L, 0~45g/L, 0~120g/L. Users can choose the appropriate range according to their own needs. Regarding the material of the sludge concentration sensor, we provide PVC, stainless steel and titanium alloy options. PVC has low cost and is suitable for most sewage monitoring applications.

Sludge concentration sensor principle

Based on infrared scattered light technology, that is, the infrared light emitted by the light source will be scattered when passing through the sample to be measured during the transmission process, and the intensity of the scattered light is directly proportional to the concentration of suspended matter. The suspended solids(sludge concentration) sensor is equipped with a scattered light receiver in the 140° direction, and the suspended solids concentration value is obtained by analyzing the intensity of this set of scattered light.

Sensor Specification

Delfino company focuses on the research, 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. Monitoring the sludge concentration value in the sedimentation tank is to ensure the normal operation of the sedimentation tank and the effective treatment of sewage. By monitoring the sludge concentration value via the online MLSS sludge concentration sensor, the accumulation of sludge can be detected in time to avoid excessive sludge accumulation causing blockage and operational problems in the sedimentation tank. In addition, monitoring sludge concentration can also help operators understand the sludge treatment effect, adjust the treatment process in a timely manner, improve treatment efficiency and save operating costs.
