GENERAL INFORMATION
The screening is the first step which must be considered in a civil or industrial wastewater treatment plant. Its purpose is to intercept and remove suspended solid particles that can damage and / or slow down the depurative processes and plant equipment.
The screen screw compactor with self cleaning teeth is specially designed for fine screening of sewage at the entrance of the plant or in many industrial applications; generally, it is installed downstream of a coarse screen.
It is multifunctional screen as includes the following operations
- Screening
- Lifting and washing of the screened material
- Compacting / dewatering
- Discharge
The filtration level is defined depending on the type and amount of material expected and according to the scheme of the purification process adopted.
Thanks to the screen filter consisting of a semi-cylindrical basket, this machine is able to block the small suspended solid particles (larger than the screen spacing), lifting them out of the water flow, by means of a screw, compact and convey them to discharge, placed at the top of the machine. During lifting, the material is washed to remove soluble organic substances.
