Effluent treatment unit in anaerobic element

DESCRIPTION

This unit provides the anaerobic environment in which, micro-organisms can digest pollutants found in the water. One of the products of the reaction is oxygen.

The process is carried out by adding water, requiring treatment, to a solid-liquid fluidised bed.

The unit is mounted on an extruded aluminium section (or stainless steel if desired) with small wheels.

This unit is designed for various levels and fields of study.

Technical documentation and instructions are provided.
