It’s a tradition that goes back to our company’s founding as a decanter centrifuge service provider. From the beginning, we’ve worked with municipal wastewater customers to enhance the performance of these essential solids separation technologies.
The first Centrisys decanter centrifuge for dewatering, installed in 1989, is still in operation today, along with over 1,000 other Centrisys dewatering systems in municipal plants worldwide.
Our centrifuges deliver the driest cake possible at the lowest HP per GPM of flow of any decanter on the market, which results in more savings for you year after year. Customers have reported significant annual cost reductions including:
- 96% reduction in fuel consumption while maintaining 24% cake solids
- 33% reduction in polymer consumption

We’ve worked closely with our municipal customers to overcome a key challenge of the thickening process: polymer costs.
The result, the THK thickening system, is expertly engineered to supersede older thickening technologies – gravity belt and rotary drum – by requiring no polymer under normal conditions (150 SVI). Typical sludge thickening applications include:
- Primary sludge
- Secondary (waste activated) sludge
- Oxidation ditch sludge
- Digested sludge
- MBR (membrane bioreactor) sludge
- Dilute pulp and paper waste prior to dewatering
- Concentration of food processing waste
- Concentration of algae
- Concentration of yeast
