The new PPS polymer preparation system is a complete, automated polymer preparation and dosing system designed to deliver consistent polymer activation before it ever reaches the sludge. Field-proven in the North American wastewater and biosolids markets, the technology made its debut at the WEFTEC 2026 conference and tradeshow. PPS addresses a critical but often overlooked part of the dewatering process: how polymer is prepared and activated before being introduced to sludge. Polymer can represent 30 to 50% of sludge processing costs, making effective preparation an important opportunity for facilities looking to control operating expenses. When polymer is not fully activated, facilities may compensate by increasing the dose, paying for additional chemistry without addressing the source of inconsistent performance. The PPS Polymer Prep System is engineered around the polymer preparation process itself, controlling the conditions that influence polymer dispersion, maturation and solution consistency. Automatic flow measurement and ratio control for water and polymer metering help maintain a consistent working solution concentration. A dedicated injection ring rapidly and uniformly disperses polymer into the water stream to support effective activation. An engineered octagonal tank and specialized mixing promote polymer hydration and chain extension while limiting excessive shear. Solution development is monitored to help verify readiness rather than relying on a fixed timer alone.Instrumentation monitors polymer and water flow, pressure, temperature, tank level, valve position, compressed-air supply and leakage, with remote access and diagnostics available. The PPS Polymer Prep System is available in multiple sizes and can support municipal and industrial wastewater treatment, sludge thickening, centrifuge and decanter dewatering, belt and screw press applications, dissolved air flotation sludge handling, and packaged or mobile treatment systems. — Centrisys/CNP, Kenosha, Wis.
