Concentration measurement on primary sludge

Product catalog summary

Introduction
The document discusses the process optimization in wastewater treatment through online concentration measurement, specifically focusing on primary sludge. It highlights the importance of measuring the concentration of dry matter for optimal purification and treatment processes.

Online Measurement of Primary Sludge
Primary sludge is formed after the removal of large contaminants, grease, and sand, and is either sent directly to a digester or to a thickener. Accurate measurement of dry matter content is crucial for optimal digestion efficiency and sludge load calculation. The MicroPolar LB 566 system is designed for these applications, providing reliable and accurate measurements of dry matter content.

Measuring Principle
The MicroPolar system utilizes the dielectric properties of water to generate microwaves that interact with water molecules. This interaction results in phase shift and attenuation, which are proportional to the water content, allowing for precise concentration determination. The system's multi-frequency technology ensures stable and reliable measurements, unaffected by interferences.

Customer Benefits

Accurate determination of total dry matter load to the digester.
Optimization of the anaerobic digestion process.
Cost reduction through optimized use of flocculants.
Improved pump utilization, avoiding blockages and ensuring efficiency.
Non-optical measurement, reducing maintenance needs.

Technical Features

High accuracy with less than 0.2 wt.% dry matter content deviation.
Representative results by detecting the entire material flow.
No component wear, unlike other technologies.
Reliable measurement with a single calibration factor for different sludges.
Suitable for both industrial and municipal wastewater.

Company Overview
