DINOTEC’s DIANA LB model of biological beds is made of GRP through continuous winding of fiberglass-reinforced polyester threads, and has a horizontal, cylindrical shape.

This equipment corresponds with a small load. It is supplied with a large, specific, surface, plastic filler and, together with the settler-digester DIANA, is the best solution for treating wastewater coming from small populations. In this case, the settler-digester reduces the load applied to the biological bed.
