Sludge Recycling

Self-contained BOD-measurement with activated sludge

The unique measurement system of the BioMonitor® from LAR Process Analysers AG with the original activated sludge performs optimally when a permanent activated sludge supply (for example from the aeration tank) is provided.

Whenever there is no continuous activated sludge supply available, the BioMonitor® with Sludge-Recycling is the right choice.

After the first supply, the activated sludge is circulated through the BioMonitor® with aid of the Sludge-Recycling Unit.

The Sludge Recycling works exactly like the sedimentation tank of the treatment plant. Thereby the measuring system becomes independent from a permanent activated sludge supply.

In combination with the Sludge Recycling Unit the BioMonitor® works independently, just like small treatment plants everywhere!

A unique measuring principle, requiring minimum maintenance

The measurement of BOD with the aid of the original activated sludge has been achieved in an instrument design which meets the high requirements of the continuous operation in waste water treatment plants.

The instrument design which has been patented by and awarded to LAR Process Analysers AG, embodies a high standard of operational safety and requires very little maintenance.

This is testified by the measurement of oxygen with air-oxygen sensors that do not suffer from conventional fouling problems.

The self-cleaning reactor cascades and the maintenance-free sample preparation FlowSampler minimize the need of maintenance of the BioMonitor® and safeguard a problem-free continuous operation with lowest operation costs, for many years.
