Tube Deck & Fab Media

Tube settlers use multiple tubular PVC channels at an angle of 60°, adjacent to each other, combined together to form a tube deck, for an increased effective settling area. The flocculated water enters the tube deck from the bottom and flows upward between them. As the water moves upwards, solids settle onto the surface area provided by the tube surface. Heavy Solids continue to slide down the tube surfaces to the collection hopper.
Application Areas:
Raw Water Treatment
Sewage Treatment
Primary Effluent Treatment
Advantages of Tube Settlers : The advantages of tube settlers can be applied to new or existing clarifiers/basins of any size : It is possible to cut coagulant dosage by up to half while maintaining a lower influent turbidity to the treatment plant filters. Less filter backwashing equates to significant operating cost savings for both water and electricity. New installations using tube settlers can be designed smaller because of increased flow capability. Flow of existing water treatment plants can be increased through the addition of tube settlers. Tube settlers increase allowable flow capacity by expanding settling capacity and increasing the solids removal rate in settling tanks.
