DAF Pre Filter System
Our automated pre filter system consists of a metal filter screen and a spiral shaped scraper which continuously cleans the screen without the need for backwash or crossflow. This is achieved by the system automatically cleaning itself over 500 times every minute. Automatic self-cleaning water filter designed for ultra-high and variable TSS of up to 25,000 ppm.
The system operates on the core principles of a mechanical filter. During normal operation solids are collected at the bottom of the housing, away from the filter, while filtered water flows continuously through the outlet. An automatic purge valve opens and ejects the concentrated solids with a minimal amount of water loss. TSS and BOD are reduced without the introduction of any chemicals or additional pollutants. Collected solids are concentrated to a sludge that can be further dewatered as desired.
- Self cleaning / no backwash cycles required
- TSS and BOD reduction without chemicals
- Small footprint / cost effective
- Capable of filtering wastewater with ultra high TSS up to 25,000 ppm
