MEASUREMENT SOLUTIONS FOR WASTEWATER TREATMENT Process optimisation with online measuring system for municipal and industrial wastewater treatment plants

WATER TREATMENT IN THE SEWAGE TREATMENT PLANT A wastewater treatment plant typically consists of mechanical, biological, and chemical treatment stages. These three processes produce various types of sludge that require special treatment. The experts for measurement solutions Berthold‘s microwave system is wear- and tear-free and thus perfectly tailored to applications in wastewater treatment. Regardless of whether information on water concentration, dry content or moisture is required, all our devices distinguish themselves by their high accuracy and reliability.

CONCENTRATION MEASUREMENT ON PRIMARY SLUDGE After gross impurities, grease and sand have been separated, organic matter and undissolved particles are transferred to a settling tank for sedimentation. The primary sludge produced here is transported either directly to the digestion tower or to the thickener for further treatment. When transporting the sludge to the digestion tower, it is necessary to know the exact dry content, which thus leads to an exact calculation of the sludge load and an optimal anaerobic digestion process. Flocculants are added to further thicken the sludge which ensures...

CONCENTRATION MEASUREMENT AT THE SECONDARY CLARIFIER AND RETURN SLUDGE CONCENTRATION MEASUREMENT DURING SLUDGE THICKENING Sludge activation and the secondary clarification are frequently the next process unit. After aeration, the sludge is fed into the secondary clarifier and settled. In this tank, different zones are formed, consisting of purified water and sludge layers. A portion of the sludge is returned for aeration and the heavy settled sludge (secondary sludge) is directed to the thickener. The measuring system monitors both the returned sludge concentration as well as the solids content....

CONCENTRATION MEASUREMENT AT THE DIGESTION PROCESS CONCENTRATION MEASUREMENT DURING SLUDGE DEWATERING After the sludge has been thickened, it is still biologically active. Through the anaerobic digestion process, digestion gas is produced with the help of microorganisms. After about 20 days in the digestion tower, the sludge is stabilised and removed from the process for further treatment. To run the process as efficiently as possible, it is necessary to know the exact dry content in the inlet, because the digester gas yield depends, among other things, on the dry matter. Berthold‘s microwave-based...
