High-performance cationic flocculants engineered for municipal wastewater, sludge dewatering, and paper retention across the UK.
The Greater London metropolitan area presents one of the most intricate urban water management and industrial wastewater landscapes in Northern Europe. Driven by the stringent mandates of the UK Environment Agency (EA), the Water Industry National Environment Programme (WINEP), and the ongoing modernization under the Thames Water Asset Management Plan (AMP7/AMP8), water utility operators and industrial process engineers require chemical flocculants that guarantee ultra-high solids capture, rapid cake formation, and minimal chemical residue.
As a global premier manufacturer, Qingdao Oubo Chemical Co., Ltd. supplies customized Cationic Polyacrylamide (CPAM) formulations tailored to the precise rheological demands of London’s municipal sewage treatment plants (such as Beckton and Crossness), civil infrastructure projects (including TBM tunneling slimes from HS2 and Tideway), and regional recycled paper and board packaging facilities along the Thames Estuary.
Engineered via advanced biological enzymatic synthesis for superior linear chain polymer length, optimal cationicity, and maximum bridging efficiency.
Unlike traditional chemical synthesis, Oubo utilizes patented biological enzymatic methods for acrylamide monomer preparation. This yields ultra-pure monomers, suppressing unwanted cross-linking and assuring soluble, linear high molecular weight structures up to 15 million Daltons.
Synthesized by copolymerizing acrylamide with cationic monomers such as DAC (Acryloyloxyethyltrimethyl ammonium chloride) or DMC (Methacryloyloxyethyltrimethyl ammonium chloride), allowing pinpoint control of charge density from 10% to 80% mol to match dynamic sludge zeta potentials.
Designed for environmentally sensitive discharge zones like the Thames catchment, Oubo CPAM features residual monomer levels reliably below 0.01% (1000 ppm), satisfying rigorous UK Environment Agency water toxicology limits.
| Parameter Grade | Charge Density (Mol %) | Molecular Weight (Million) | Dissolution Time | Primary London Application Scenarios |
|---|---|---|---|---|
| Oubo CPAM Low-Charge | 10% - 20% | 10 - 12 Million | ≤ 50 Mins | Paper retention, primary sedimentation, low-organics mineral slurry dewatering. |
| Oubo CPAM Medium-Charge | 30% - 40% | 8 - 12 Million | ≤ 45 Mins | Municipal activated sludge (belt filter press & centrifuge dewatering), river dredging. |
| Oubo CPAM High-Charge | 50% - 60% | 6 - 10 Million | ≤ 40 Mins | High-organic industrial effluent, food processing wastewater, dissolved air flotation (DAF). |
| Oubo CPAM Ultra-High Charge | 70% - 80% | 6 - 8 Million | ≤ 40 Mins | Textile dyeing wastewater, high-charge biological sludge neutralization, specialized decanters. |
Proven operational performance across critical UK infrastructure and processing sectors.
In municipal wastewater facilities around East and South London, secondary biological sludge presents high water-retention characteristics. Oubo CPAM effectively neutralizes negative surface charges on biological solids, aggregating micro-flocs into large, shear-resistant macropackages. This increases cake dry solids content in centrifuges and belt presses by 3%–6%, substantially cutting sludge transport and incineration costs.
Major infrastructure projects—such as tunneling beneath the Thames and high-speed rail development—generate high volumes of clay, silt, and bentonite slurries. Oubo’s quick-dissolving cationic polymers rapidly clarify muddy water circuits, enabling rapid recycling of drilling fluids and rapid discharge compliance under Environment Agency permits.
For papermaking plants Operating along the Thames corridor, Oubo CPAM functions as a high-efficiency retention aid, dry-strength agent, and drainage accelerator. It maximizes fine fiber retention, enhances web dewatering speed, reduces wet-end chemical waste, and clarifies white water loops for zero-liquid-discharge operational goals.
Qingdao Oubo Chemical Co., Ltd. was established in 2011 and is headquartered in the Free Trade Zone of Qingdao, China. Over the past decade, Oubo has maintained a steady business growth rate of over 10% per year, achieving an annual polyacrylamide production capacity exceeding 50,000 Metric Tons.
Our quality management system is strictly certified under ISO 9001:2015. We purchase high-grade raw materials from premier global chemical giants such as SINOPEC and Eni. Every batch of polymer manufactured across our fully automated production lines undergoes rigorous triple-stage quality testing by our dedicated QC team prior to dispatch.
Oubo is committed not only to superior chemical performance, but also to environmental stewardship throughout polymer production and application. Our specialized technical engineering team actively supports clients across pre-sales evaluation, laboratory jar testing, dosage optimization, and on-site trials in London.

Pioneering renewable bio-feedstocks to drastically lower the carbon footprint of polymer production, supporting Net-Zero carbon targets across UK municipal utilities.
Developing rapid-dissolving micro-powder and emulsion variants that reduce preparation times to under 20 minutes, minimizing energy consumption in automated dosing systems.
Advancing specialized cationic polymer chains engineered to eliminate aquatic toxicity concerns in direct-discharge environmental applications.
Technical guidance for engineers, procurement managers, and water treatment specialists in London.
Selection depends on sludge volatile organic content (VS/TS ratio) and dewatering equipment. Typically, digested municipal activated sludge in London responds best to medium-to-high cationic charge (30% to 50% mol) paired with a high molecular weight (8–12 million). We recommend laboratory jar testing and cylinder free-drainage evaluations to pinpoint the exact dosage.
Yes. All Oubo polyacrylamide products exported to the UK comply with UK REACH requirements, supported by complete SDS documentation, toxicological profiles, and regulatory certificates necessary for smooth customs clearance into London ports.
CPAM powder should be dissolved to a concentration of 0.1% to 0.3% (w/v) using clean water at temperatures between 15°C and 30°C. Gentle stirring (around 200–400 rpm) for 45 to 60 minutes ensures full polymer chain extension without mechanical degradation.
Standard production time for 20ft/40ft container orders is 7 to 10 working days from order confirmation. Direct ocean freight transit from Qingdao to London ports typically takes 28 to 35 days, with expedited shipping options available for urgent plant requirements.
