The operating principle of a bio-purifier is simple.

From Vestelli you get proven effective wastewater systems. Long-lasting and worry-free Finnish Vestelli treatment solutions are an environmental act.

The bio-purifier is a continuous greywater purifier, and its operating principle is simple. It operates by aerating the wastewater, which is enhanced by biological purification. The bio- layer that accumulates on the surface of the bio-modules strengthens the purification process of nutrients in the wastewater.

The operating principle of a biopurifier

Greywater is led through a drainage system to the first compartment of the tank.
The large volume of the first compartment creates the conditions for proper separation of fats and solids.
After separation, the water moves by gravity from the bottom of the second compartment to the biomodules.
In biomodules, greywater is aerated with small oxygen bubbles and the process results in the removal of 99% of the most problematic substance in greywater, i.e. organic matter.
In the third compartment, the purified water is stabilized before being transferred from the bottom of the compartment to the unloading site.
A coarse filter in the outgoing drain completes the perfect cleaning result.
