1. Introduction
Rotary drum screw is a continuous and effective fine screen removing suspended solids. It is mainly applied in pre-treatment stage of sewage treatment plant or industrial screening. Under the specified screening condition , it can remove 30 - 60% of suspended solids from screened sewage.
2. Working Principle
When the rotary drum screen runs , the sewage or other raw water will flow into the screen inlet tank via inlet pipe lifting by pump. Through eliminator (or water distribution pipe) , the sewage will flow into the front of screw screen and pass through the screen surface and flow into the drum. Finally , the sewage will flow out at the bottom of the drum. The suspended solids will be left on the drum surface. With the vibration of the drum surface , the suspended solids will be transported from one side to another side and will be discharged by the discharging mechanism.
3. Features
- This unit will adopt wedge-type as filtering parts , easy for fluid passing through , non-blocking.
- Use stainless steel grid which apply for high temperature and high concentration of screening.
- This unit will use drum type , large filtering space. Thus for the same treating capacity , it has advantage of compact structure , small footprint , low energy consumption.
- This unit will use backwash nozzle to cleaning the debugging among drum screen. For the backwash start-up and stop-down , it can be controlled automatically or manual control.
- This unit can achieve continuous operation , automatic sludge discharge , high degree of automation.
- Completely closed design in case of secondary pollution.
- For the whole unit , it will be made up of stainless steel.
