The THK thickening centrifuge from Centrisys is designed to thicken waste-activated sludge with little or no polymer. The system produces up to 8 percent cake solids running at flow rates of up to 1,000 gpm. Applications include secondary sludge, primary sludge, oxidation ditch sludge, digested sludge and MBR sludge.“Depending on the sludge, the characteristics and the demand of the plant, we have the option to run no polymer, or if there’s a scenario where a plant doesn’t want to run three machines or one is down for maintenance, we eliminate the third redundancy by injecting a low dosage of polymer
