Wastewater treatment from 2 to 8 PE, according the Walloon agreement, active sludge

Specifications

This Boralit system is standard conceived of 3 tanks, of which the first one a separate tank, and the last 2 in monoblok. Namely a pre-treatment (primary sedimentation), aeration and a clarifier (secondary sedimentation). All manufactured in high quality PE, a material with multiple advantages.

OPERATION OF AN ACTIF SLUDGE SYSTEM

The small wastewater treatment plants from Boralit working according the active sludge system. The First tank(s) is a pre-treatment tank and functions like a septic tank. The tank in the middle is intensively aerated. In this tank is a mixture of waste water and biomass. This biomass develops in the waste water, in the form of micro-organisms.

In the water treatment plant of Boralit, the aeration is used for both the oxygen supply as for mixing the contents in the reactor. By continuously aerating the installation, the aerobic bacteria are growing.

The separation between the treated water and the activated sludge takes place in the clarifier. A part will be returned to the aeration tank (middle tank). This by means of a sludge return. This increases the purification process significantly. Occasionally the sludge should be removed from the system, so the biomass in the aeration tank is kept at the desired level.

The WZ wastewater treatment plant is based on the active sludge technology, like most central municipal treatment plants.

Designs:
They are available in 2-5  PE and 5-8  PE.
Consisting of  1 tank + a monoblok of 2 tanks.
It is possible to install several systems in parallel.
