🌡️ Slurry Heat Exchangers (Shear-Driven Anti-Fouling Velocity 1.5-2.5 m/s, High-Viscosity)

Sludge Pasteurization Spiral Heat Exchanger Calculator

Size closed-loop sludge-to-sludge and hot-water-to-sludge regenerative spiral heat exchangers for municipal biosolids thermal pasteurization ($75^circ ext{C}$ for 30 minutes): calculate fouling resistance factors and automated Clean-In-Place ($CIP$) flush velocities ($>2.0 ext{ m/s}$), recover $>80%$ of thermal energy, and biosolids yields.
