GDF - Combined wastewater pre-treatment unit

Wastes, passing through the screen basket, are screened and the bigger solid particles are removed.

Then, effluents pass in the tank (hopper) section, where finer solids particles are allowed to settle down and are removed by a low rotating shaftless screw system. As an optional, the unit can be designed with an oil/grease removing system.
