Space-Saving Compact Pretreatment Unit | For Small-Scale Industrial & Commercial Use

Compact Units Pretreatment Plants For Wastewater Treatment Description

This Combined Pretreatment Compact Unit equipment is fed by a pump or to gravity, through a fixed pipe. The effluent passes through a screw screen that removes the most large solid particles, then goes to a sedimentation tank where the particles sedimented are then removed by a system of scews. As an option you can install the system for removal of fats and suspended oils. 

Combined Screening Component

Dependable, complete and compact unit Performing the following process steps:

• fine screening
• Screenings dewatering
• Grit separation
• Grit dewatering
• Grease separation and removal (optional)

Combined Screening Working Principle

For the removal of suspended particles such as oil, grease, and other substances, the unit employs a system of paddles made from stainless steel wire. The settling tank is equipped with an air blower to further facilitate the separation of organic matter and the settlement of grit. Larger units may be fitted with two blowers for increased efficiency.

1. The wastewater firstly enters the tank where a screw screen is placed. 
2. Big size solid materials are filtrated by the screw screen and a screw conveyor moves the solid materials captured up to the discharge point. At the end of the conveyor, they are pressed by the compaction unit before discharge.
The water which has still solid materials in smaller sizes flows through the sedimentation tank. The particles are settled by time and a horizontal screw 
conveyor transports them to the collection hopper. 
3. Finally, they are conveyed by the grit removal 
screw conveyor to the discharge point.
