Polymer Make-Up & Dosing

Polymer performance depends on preparation as much as product. Proper wetting without shear damage, adequate ageing for the chains to uncoil, the right make-up concentration, and accurate flow- and solids-paced dosing with good mixing at injection all ensure the polymer is fully active where it meets the sludge.

Polymer make-up and dosing — correct preparation, ageing and flow-paced injection that get full value from every kilogram of polymer.

Conditioning — polymer (with correct selection, make-up and dosing) or inorganic coagulants, guided by jar and CST testing — flocculates the solids so they release water readily; dewatering then separates that water mechanically. Belt filter presses, decanter centrifuges and screw presses each trade cake dryness, polymer demand, throughput and energy differently, and thermal drying (belt, fluidised-bed, rotary-drum or solar) pushes dryness further where disposal or reuse demands it.

Reynolds & Bauhm engineers the whole sludge line — stabilisation, conditioning, dewatering and drying — selecting and sizing equipment on cake dryness, polymer demand and whole-life cost, so wet tonnage and disposal cost are driven down at source.

Sludge treatment converts a dilute, unstable, high-volume waste into a stabilised, dewatered, disposable product, through a chain of thickening, stabilisation, conditioning, dewatering and sometimes drying. Because disposal is priced largely by wet tonnage and governed by stabilisation grade, decisions made in this chain dominate the whole-life cost and the available disposal routes.
