High-molecular-weight cationic polymers tailor-made for optimal sludge conditioning and rapid solid-liquid separation.
The industrial wastewater and municipal water treatment sectors across the United Kingdom are undergoing transformative shifts. Driven by stringent regulations enforced by the UK Environment Agency (EA), Water Services Regulation Authority (OFWAT), and regional water authorities under the Asset Management Plan (AMP7 and AMP8) operational cycles, facility operators face unprecedented pressure to increase sludge dewatering efficiency while minimizing chemical footprint.
Cationic Polyacrylamide (CPAM) serves as a core chemical agent in this ecosystem. Modern wastewater treatment plants from Thames Water to Severn Trent and Scottish Water require highly specialized cationic polymers with precisely tuned charge densities (ranging from 10% to 80%) and high molecular weights (up to 15 Million Daltons). Proper polymer selection directly impacts cake dryness, centrate clarity, and operational expenditure in high-throughput centrifuge, belt press, and screw press equipment.
Oubo Chemical produces Cationic Polyacrylamide (CPAM) through high-purity biological enzymatic monomer synthesis, ensuring exceptional chain length and precise charge distribution.
Cationic Polyacrylamide is a linear water-soluble polymer synthesized by copolymerizing acrylamide with cationic monomers such as acryloyloxyethyltrimethyl ammonium chloride (DAC) or methacryloyloxyethyltrimethyl ammonium chloride (DMC). In aqueous systems containing negatively charged suspended particles (such as organic sludge, pulp fibers, or dye molecules), CPAM performs through dual mechanisms: Charge Neutralization (destabilizing colloidal suspensions) and Polymer Bridging (aggregating micro-flocs into large, rapid-settling macro-flocs).
| Polymer Grade Class | Cationic Degree (%) | Molecular Weight (Million Da) | Dissolution Time (Mins) | Primary Industrial Application (UK) |
|---|---|---|---|---|
| CPAM Very Low Charge | 5% - 15% | 10 - 14 | ≤ 60 | Industrial inorganic effluent, paper mill primary clarification |
| CPAM Low-Medium Charge | 20% - 35% | 10 - 15 | ≤ 60 | Pulp & paper retention aids, combined primary/secondary sewage sludge |
| CPAM High Charge | 40% - 60% | 8 - 12 | ≤ 45 | Biological activated sludge, belt filter press dewatering |
| CPAM Ultra-High Charge | 65% - 80% | 6 - 10 | ≤ 45 | Textile dyeing effluent, high organic/grease sludge, decanter centrifuges |
Our specialized PAM formulations address unique regional processing requirements across the UK market.
UK water utilities demand high mechanical shear resistance during decanter centrifuge and belt filter press operations. Oubo CPAM powders deliver large floc formation with rapid water release, ensuring clear supernatant filtrate and cake dryness exceeding 25-30% dry solids (DS).
Serving recycled containerboard and specialty tissue mills across England, Scotland, and Wales. CPAM acts as a retention aid, wet-end filler capture agent, and dewatering accelerator. It enhances paper sheet strength while recovering fine fibers from white water loops.
High-cationic polyacrylamides neutralize strong anionic charges from reactive and disperse dyes in textile processing effluent. Provides effective color removal, COD reduction, and rapid settling in primary DAF (Dissolved Air Flotation) systems.
For North Sea offshore drilling operations and onshore industrial fluid handling. Our non-ionic and cationic polymers function as friction reducers, fluid-loss control agents, and shale stabilizers in demanding brine environments.
Optimized for aggregate washing, clay settling, and coal washing tailings filtration. Facilitates clear recycling of process water, reducing raw water intake and meeting strict UK Environmental Agency discharge parameters.
High-purity anionic and cationic polymers specifically formulated for juice clarification, sugar beet wash water recycling, and food waste sludge dewatering with minimal residual monomers.
