Precision-engineered flocculants designed for rapid solid-liquid separation and high-shear industrial applications.
An authoritative technical analysis of synthetic linear polymers (PAM) manufactured via advanced bio-catalytic pathways for extreme industrial environments.
Unlike traditional chemical synthesis using sulfuric acid or copper catalysts, our state-of-the-art bio-enzyme microbial catalyst method yields Acrylamide (AM) monomer with greater than 99.9% purity. This eliminates trace copper ions and residual organic impurities, resulting in Polyacrylamide chain structures with ultra-high molecular weights (up to 30 Million Daltons) and extremely low monomer residue (<0.05%).
Polyacrylamide (PAM) is a water-soluble synthetic polymer formed from acrylamide subunits (CAS 9003-05-8). By copolymerizing acrylamide with targeted functional monomers (such as DAC, DMC, or Acrylic Acid), we precisely adjust charge densities ranging from 5% to 80% ionic substitution to match specific zeta-potentials in complex industrial effluents.
Our polymers exhibit exceptional chain extension in aqueous solution. By simultaneously executing electrostatic charge neutralization of suspended colloids and long-chain polymer bridging, Oubo PAM forms massive, rapidly settling flocs (micro-flocculation to macro-flocculation) under high-shear hydrodynamic conditions.

Our O'brien brand polyacrylamide products are tailored to overcome severe operational challenges across diverse industrial sectors.
As a highly efficient flocculating agent, Polyacrylamide is primarily utilized in solid-liquid separation processes, including sedimentation, clarification, sludge thickening, and mechanical sludge dewatering (centrifuges, filter presses). Increasingly stringent global environmental regulations have accelerated the adoption of high-efficiency polyacrylamides.
In municipal sewage treatment, CPAM effectively neutralizes the negative surface charge of biological sludge particles, building compact flocs that yield dense filter cakes and crystal-clear filtrate. Beyond municipal infrastructure, Oubo PAM is widely adopted in leather processing, paper manufacturing, citric acid clarification, vegetable protein extraction, textile dyeing, pharmaceuticals, and incense manufacturing.
In the paper industry, specialized APAM and CPAM polymers act as dry strength agents, retention aids, drainage aids, and dispersants. By incorporating Oubo PAM into the wet-end process, paper mills significantly enhance physical sheet strength, minimize fine fiber and filler loss, and optimize white water circuit clarification.
Polyacrylamide is indispensable across upstream oilfield operations. In oil drilling, PAM functions as a fluid loss control agent, shale inhibitor, viscosity modifier, and borehole lubricant. It efficiently carries drill cuttings to the surface while sealing formation micro-fractures.
In tertiary oil recovery (EOR), ultra-high molecular weight Anionic PAM increases swept water phase viscosity, improving water-to-oil mobility ratios and driving residual hydrocarbons out of low-permeability reservoirs. Specialized thermal- and salt-resistant polymers perform under harsh downhole conditions.
In mineral processing, Oubo Polyacrylamide accelerates solid-liquid separation in thickeners and tailing ponds. It facilitates mineral washing, leachate filtration, and centrifugal separation across precious and base metals extraction including Gold, Silver, Copper, Iron, Nickel, Aluminum, and Uranium.
In coal preparation plants, high-molecular weight APAM aggregates ultrafine coal slurry particles, enabling rapid clarification of recycled process water and efficient tailings dewatering.
Sugar Refining: Food-grade PAM plays a vital role in juice clarification and flotation, rapidly separating insolubles from sugarcane or sugar beet extracts to yield high-purity sucrose solutions.
Textile Industry: PAM serves as a sizing agent, finishing auxiliary, and fabric processing compound. It imparts smooth protective coatings on warp threads, reducing yarn breakage during high-speed weaving while serving as a primary coagulant aid in textile dyeing wastewater remediation.
