The clear water extraction system of SBR purification plants for the procedure-appropriate derivation of the biologically cleaned sewage – everywhere where purification plants are in use!
The Flexi clear water extractor for SBR purification plants meets all requirements for clear water extration system.
1. Fill / animation phase:
When the extractor is in the parking position, the intake opening is above the maximum water-level, so that floating sludge or sewage can not get into the mechanism!
2. Start of the extraction process:
The extractor is lowered by the winch. A flexible flap prevents swimming sludge from getting into the extractor while this is being lowered. The intake element floats on the water. The position of the intake opening is approximately 30 cm below the water level.
3. Extraction phase:
The extractor floats on the water and automatically moves down gradually with the sinking water level. Due to the wide opening the clear water is drawn off completely without any whirling.
4. End of the extraction process:
At the end of the process the water-level has reached its lowest position. Extraction without whirling allows a minimum distance of only ca. 50 cm between water level and sludge surface. The winch finally lifts the extractor back into its parking position.
