Slamex Suction Clarifier

Slamex Suction and Circular clarifiers have patented wading wheel system, which has been developed for effective sludge removal, even in arctic conditions.  Thanks to the wading wheel system, the clarifier is suitable even for arctic conditions, since the wheel track does not need heating and does not freeze. The sludge removal system is designed so that it is easy to build and equip according to clients' requirements.

Slamex PI suction clarifier is peripheric driven, very reliable and easy to maintain. The patented system for keeping the wheel track unfrozen is applicable to arctic climate and construction and operation costs are lower. Biological sludge removal is fast without any sludge collectors in the bottom of the basin. The bridge and the scraper can be extended to the diameter of the basin (if required). It can be equipped with a surface sludge removal system (as an option). In large basins and with high flows basin can be equipped with extra radial overflow weirs. Flocculation area can be equipped with flocculation mixers.

Construction is designed considering torque and to remove primary sludge which has run off to secondary clarifier in case of disturbance.

The bridge moves clockwise when the scrapers move sludge to suction pipes which suck the sludge from the bottom of the basin. The driving unit is equipped with an overload switch and a rotation controller which stops the motor in case of disturbance. The amount of return sludge can be adjusted by controlling the sludge flow outside of the basin. Adjustment of the suction pipes can be done using the flow control equipment at the end of the pipe. Clarified water runs off the basin through the adjustable overflow weirs (also through extra radial overflow weirs when needed).
