The septic tank unit is a pre-treatment equipment that integrates two or three functions: removal of screenings, removal of greases and removal of sand, combined into a single equipment.
The main advantages of this equipment are:
•Reduced maintenance;
•Easy installation;
•No civil construction work required.
This equipment consists of several elements, but the main ones are: an effluent reception tank with an inlet pipe, a compactor screen for the removal and compaction of solids, a sedimentation tank where sand sedimentation occurs and a diagonal screw conveyor that elevates and discharges the sand. If needed, a screw conveyer is used to remove the fats/greases combined with air diffusers.
Regarding construction materials, the body of the unit can be made of 304L or 316L stainless steel, and the screens can be made of carbon steel, 304L stainless steel, or 316L stainless steel.
