Bacterial bed depurators 

These plants include a primary sedimentation basin for solid sediment knocking down, a basin with a low charge bacterial bed, realized with wide usable space plastic elements, and a final sedimentation basin for rejected substances of the bacterial bed.
Plants are available in various versions: - intensive bacterial bed with recircling
- regular gravity bacterial bed

LB NG, LB NI, LB NFT Series, with prefabricated modular elements reinforced concrete basins, easy and quick to assemble 

Biodishes depurators 

Biodishes offer an inert support for the biological flora to grow on, the latter playing the main part in the depuration process. The support brings the flora in touch, alternatively, with the organic matter that is in the waste water to be purified, and the atmospheric oxygen. The treatment of the sewage with biological dishes consists in the following operative phases:
- sedimentation and digestion of the primary muds for solid sediment knocking down;
- biological oxidation with biodishes
- final sedimentation and digestion of the biodishes reject
With the biodishes system it is possible to operate with high or very high BOD5 rate sewage.
This system tolerates high fluctuations in the organic charge, fitting thus all those circumstances where there may be high changes in the usage (campsites, holiday villages, motorway restaurants).
IDRODEPURAZIONE realizes these plants with metal carpentry or reinforced concrete prefabricated basins.
