View Specifications →As one of Southern Europe’s primary industrial hubs, the Metropolitan Area of Barcelona and the broader Catalonia region face dual pressures: maintaining high-throughput industrial productivity while strictly complying with European Union environmental directives and local water management frameworks governed by the Agència Catalana de l'Aigua (ACA). Severe seasonal water stress across the Llobregat and Besòs river basins has accelerated the mandate for advanced industrial water recycling, zero liquid discharge (ZLD) practices, and efficient sludge dewatering.
In this technical white paper, Qingdao Oubo Chemical Co., Ltd. evaluates the chemical dynamics, performance parameters, and economical supply chain advantages of utilizing bio-catalytic Anionic Polyacrylamide (APAM) in Barcelona’s complex wastewater environments. By replacing traditional inorganic coagulants or low-molecular-weight polymers with high-efficiency APAM, facility engineers achieve higher settling velocities, drier sludge cakes, and significant reductions in chemical consumption costs.
Oubo Chemical's bio-method synthesis eliminates hazardous byproduct impurities, producing Anionic Polyacrylamide with molecular weights reaching up to 25 million Daltons and customizable hydrolysis levels (10%–50%). This guarantees rapid bridging kinetics even in high salinity or variable pH industrial wash waters typical of the Mediterranean region.
Anionic Polyacrylamide is a water-soluble linear polymer synthesized from acrylamide and acrylate monomers. In liquid suspension, its primary function is driven by two combined physicochemical actions: Charge Neutralization and Polymer Bridging.
The high molecular weight active polymer chains extend into the liquid medium, adsorbing onto the surface of multiple suspended solid particles simultaneously. This creates robust inter-particle bridges, forming large, dense micro-flocs (flocculation) that settle rapidly out of the water column.
Negatively charged carboxylate groups ($-\text{COO}^-$) along the APAM chain react with positively charged trivalent cations (e.g., $\text{Al}^{3+}$, $\text{Fe}^{3+}$ added during primary coagulation) or mineral surfaces, neutralizing repulsive Zeta Potential forces and accelerating phase separation.
To assist chemical process managers at local Barcelona municipal facilities and chemical parks (such as the Zona Franca and Martorell industrial sectors), the table below outlines the core product specifications of Oubo Chemical's APAM range:
| Polymer Grade | Molecular Weight (Million Da) | Degree of Hydrolysis (%) | Solid Content (%) | Dissolution Time (min) | Primary Regional Applications |
|---|---|---|---|---|---|
| OUBO-APAM High MW | 18 – 25 | 20 – 30 | ≥ 88% | ≤ 50 | Besòs Basin Municipal Dewatering, Paper Retention Aid |
| OUBO-APAM Medium MW | 12 – 16 | 15 – 25 | ≥ 88% | ≤ 45 | Textile Effluent Treatment (Terrassa/Sabadell Hubs) |
| OUBO-APAM Ultra-High MW | 22 – 28 | 30 – 45 | ≥ 90% | ≤ 60 | High Salinity Industrial Water, Sand & Aggregate Washing |
| OUBO-APAM Food Grade | 10 – 15 | 10 – 20 | ≥ 89% | ≤ 40 | Sugar Refining, Beverage Wash Water, Agro-Food Processing |
Tailored chemical dosing strategies developed for key economic sectors in the Metropolitan Area of Barcelona and surrounding provinces (Girona, Tarragona, Lleida).
Serving large-scale municipal wastewater plants along the Llobregat and Besòs river systems. Our high molecular weight APAM provides dense flocs that resist shear forces in belt presses and decanter centrifuges, delivering cake dryness exceeding 25% dry solids.
Textile mills in historic centers like Terrassa and Sabadell generate complex, highly colored wastewater. Oubo APAM acts as a superior clarifying agent, aggregating colloidal dyestuff particles after coagulation to achieve high chemical oxygen demand (COD) removal rates.
In Catalonia’s packaging paper mills, APAM acts as a crucial dry strength agent and retention aid. It reduces fine fiber loss into white water, lowers raw material waste, and speeds up machine dewatering efficiency.
Food processing facilities in regional Catalonia require strict low-monomer polymer formulations. Oubo’s bio-acrylamide polymer ensures compliance with EU drinking and food-contact washing standards while maintaining high clarification speed.
Heavy industry clusters around the Port of Barcelona and Tarragona petrochemical complex utilize APAM for oily wastewater clarification, heavy metal hydroxide precipitation, and cooling tower blowdown treatment.
Infrastructure construction and aggregate quarrying near the Pyrenean foothills generate wash water loaded with clay and silt. APAM enables instantaneous settling in sedimentation basins for direct water recycling.
Established in 2011 and situated in the Free Trade Zone of Qingdao, China, Qingdao Oubo Chemical Co., Ltd. has grown into a premier global producer of synthetic polyacrylamide. Our strategic location adjacent to world-class port infrastructure allows seamless, direct sea-freight logistics straight to the Port of Barcelona (Puerto de Barcelona), providing Spanish enterprises with guaranteed supply security and unmatched cost-performance metrics.
Unlike traditional chemical synthesis that leaves unreacted monomer residues and toxic impurities, Oubo employs a state-of-the-art biological enzymatic method to produce Acrylamide monomer. This process operates under mild reaction conditions, yielding higher purity polymers with ultra-high molecular weight distribution and zero toxic byproducts—giving our customers a distinct edge under EU REACH regulations.
Our comprehensive Quality Control (QC) matrix tests every single production batch 3 times prior to packaging: raw monomer purity testing, polymer viscosity and molecular weight verification, and final dissolution rate assessment. With an annual capacity surpassing 50,000 Metric Tons, we ensure scale, stability, and zero-defect consistency.
We provide tailored container shipping solutions (FCL/LCL) directly from Qingdao Port to Barcelona. Our flexible packaging options include 25kg multi-wall paper bags, moisture-proof PE inner liner bags, and 750kg/1000kg jumbo sea-freight bags on heat-treated EU-compliant pallets.
Selecting the optimal polyacrylamide ionic type is critical for avoiding chemical waste and ensuring optimal solid-liquid separation. The table below illustrates the key differences between Anionic, Cationic, and Nonionic polymers when applied in Mediterranean industrial water systems.
| Polymer Type | Ionic Charge Character | Optimal Wastewater Type | pH Operating Range | Typical Dosage (ppm) |
|---|---|---|---|---|
| Anionic Polyacrylamide (APAM) | Negative Charge ($-\text{COO}^-$) | Inorganic suspended solids, high turbidity water, mineral slurries, primary sewage clarification | 7.0 – 14.0 (Neutral to Alkaline) | 0.5 – 5.0 ppm |
| Cationic Polyacrylamide (CPAM) | Positive Charge ($-\text{N}^+\text{R}_3$) | Organic-rich sludge, municipal secondary sludge, biological waste, tannery wastewater | 3.0 – 7.0 (Acidic to Neutral) | 1.0 – 10.0 ppm |
| Nonionic Polyacrylamide (NPAM) | Neutral / Zero Formal Charge | Acidic industrial effluents, mineral leaching tailing, high-solids suspension with low ionic strength | 1.0 – 8.0 (Strongly Acidic to Neutral) | 1.0 – 8.0 ppm |

Direct ocean vessel routes from Qingdao Port to the Port of Barcelona typically take 24 to 30 days. Our logistics team handles export documentation, palletization, and custom customs clearance support, ensuring seamless delivery directly to your facility warehouse in Catalonia.
For high-shear mechanical dewatering equipment like decanter centrifuges or high-pressure belt filter presses, we recommend our high to ultra-high molecular weight APAM (18–25 million Daltons) with medium charge density. The high molecular weight chain provides superior shear resistance, preventing floc degradation under high G-force centrifugation.
APAM dry powder must be dispersed evenly into water using a dedicated polymer preparation unit with continuous mechanical stirring at 200–400 RPM. Water temperature should ideally be between 15°C and 30°C. Never dump dry powder rapidly into stagnant water, as this causes outer hydration layers to form un-dissolved "fish-eye" lumps.
Yes. We specialize in custom polymer formulation. Depending on your laboratory jar test results or effluent analysis, we can adjust the degree of hydrolysis from 10% to 50% to precisely match the ionic charge balance of your process water.
