Concentration measurement on primary sludge

Process optimization through online concentration measurement

(PresseBox) (Bad Wildbad, )
A wastewater treatment plant usually consists of a mechanical, biological and chemical treatment step. These three processes produce sludges of different types that require special treatment. In order to perform an optimal purification, it is essential to know the concentration of dry matter. Berthold‘s LB 566 provides the total solids content which facilitates the calculation and optimises the use of polymers and flocculants.

Online measurement of primary sludge

After the separation of large contaminants, grease and sand, undissolved particles are brought to sedimentation in a clarifier. These deposited substances are referred to as primary sludge.

The primary sludge is conveyed either directly to the digester or to the thickener for further treatment. In the case of direct sludge pumping to the anaerobic digester, it is important to measure the exact dry matter content, which provides an accurate sludge load calculation, thus achieving optimal digestion efficiency.

During further thickening of the sludge, flocculants are added to the process, which leads to optimised dewatering grades. The MicroPolar LB 566 measuring system was developed especially for these applications. The microwave transmitter measures reliably the dry matter content and offers excellent accuracy. Representative measurement results are achieved due to the fact that the entire material flow in the pipeline is detected, even for large pipeline diameters.

BERTHOLD TECHNOLOGIES GmbH & Co. KG

As a world technology leader in the field of radiometric measuring systems, Berthold products convince with outstanding measuring performance and reliability. The main fields of application are, for example, in chemical & polymers (etc. fertilizer industry), steel and power plants, mining & mineral processing, waste & recycling, refineries, paper, glass and as well as in the food industry (etc. sugar beets). In addition, microwave measuring systems for the determination of moisture and concentration belong to our extensive portfolio. The production of high-quality measuring systems for industry and research began more than 70 years ago in Bad Wildbad in the Black Forest.
