Waterneer Solution and the Results:
80% of the pond was full of solids – the fiber from the paper mill. A dredger was used to pull the waste slurry and pushed through the Waterneer machine. Solids were taken to a landfill around 300 meters away. The clean water was sent back to the other end on the pond separated with a flexible barrier. In six months 380,000 M3 of wastewater was treated and clarified without any production disruption. Paper mill has installed a filter system to arrest the short fibers. Customer is evaluating Waterneer machine to replace the filter to save cost and implement a better recovery of fiber and once step process.
