Start‐up April, 2015

Beneficial Reuse: End Product is to be given away or sold in bulk for agricultural use.


Project Overview: The Tri‐Lakes Biosolids Regional Drying Facility brings in material from three WWTP’s in the Branson area. Three Centrifuges and the Bio‐Scru® were the main components of the facility. Each of the three feeder plants installed a centrifuge with one of the plants also installing the dryer. Millions of dollars in construction cost were saved by placing all equipment in existing buildings that previously held gravity‐belt thickeners as well as the Truck Load‐Out Building. Biosolids from the outside two treatment plants are trucked to the central facility after dewatering and are then processed further using the dryer to achieve Class A Biosolids status.


Project Benefit: Tri‐Lakes will take the biosolids at 19‐21% DS and process them at a rate of 4,000 wet lbs./hr. using the Bio‐Scru® Model HSD‐30D‐28‐6 to process the material to ≥90% DS. The Company will then have the ability to give away or sell the end material for local agriculture use rather than pay for transportation and landfill tipping fees.
