Editor's Note: Innovation was a big theme at WEFTEC 2014. We'll be featuring a few of the new and better technologies found in the exhibit hall at the Morial Convention Center in New Orleans. Watch each day for the Innovation logo to learn more about new products displayed at the clean-water industry’s flagship exhibition and conference.

Centrisys exhibited THK Series thickening centrifuges for waste activated sludge (WAS), designed to thicken without polymer while increasing capacity. The fully automated system uses centrifugal force to increase the solids concentration of WAS for further processing.

Material is fed to the unit continuously as a moving shaft with a set of helical scrolls pushes the solids toward one end, away from the liquid moving in the opposite direction. Hydraulic assist technology and a longer cylindrical pathway help maximize capacity. The process has a small footprint. An airtight design limits operator exposure to process liquids and vapors and eliminates odors and aerosols. The manufacturer says users can expect 2.5-year payback from polymer savings, along with low operating and maintenance costs.
