According to Environment and Climate Change Canada, over 97% of waste requiring final disposal in Canada is landfilled, while only 3% is incinerated — including municipal sludge and other residual materials. Flowdehy® helps minimize this disposal burden by reducing sludge volume at the source, improving dewatering efficiency, and lowering transport and landfill costs through innovative fiber-based technology.

What is Flowdehy®?

Flowdehy® is a next-generation fiber-based sludge-dewatering aid engineered to outperform conventional press-aid products by optimizing capillary water removal and fiber network stability. It enhances performance across screw presses, belt presses, and centrifuges, delivering:

  • 5–15% higher cake dryness

  • Over 90% reduction in sludge volume

  • Improved flow and reduced clogging

  • Consistent performance across diverse sludge types

Dehydration Mechanism of Flowdehy®

Flowdehy® enhances sludge dehydration efficiency by releasing trapped water inside sludge flocs through fiber-assisted capillary action, improving cake dryness.

  • Capillary Action – Water moves along fiber surfaces for rapid drainage and improved separation.

  • Open Channels – fibers maintain clear flow paths under compression, minimizing clogging.

  • Continuous Release – The fiber network shifts slightly to let water escape efficiently.
