Engineered specifically for the intense solid-liquid separation requirements across Ho Chi Minh City’s industrial parks and municipal wastewater treatment plants.
Ho Chi Minh City (HCMC), as the economic locomotive and primary industrial hub of Vietnam, anchors the Southern Key Economic Zone (SKEZ). Encompassing massive industrial clusters such as Tan Thuan Export Processing Zone, Hiep Phuoc Industrial Park, Le Minh Xuan, Dong Nam, and Tan Binh Industrial Parks, the metropolis generates substantial volumes of complex industrial effluent daily. The convergence of high-density manufacturing—spanning textiles, garment dyeing, food processing, seafood packaging, chemical synthesis, and electronics—presents rigorous challenges for local Effluent Treatment Plants (ETPs) and municipal wastewater facilities.
Under the stringent environmental mandates enforced by Vietnam’s Ministry of Natural Resources and Environment (MONRE), specifically Decree No. 08/2022/ND-CP and technical standards QCVN 40:2011/BTNMT (Industrial Wastewater National Technical Regulation), industrial operators in HCMC must adhere to aggressive COD, BOD, Total Suspended Solids (TSS), and sludge moisture limits before discharging treated water into the Dong Nai or Saigon River basins.
Tropical climates with high humidity and ambient temperatures (ranging from 27°C to 35°C year-round in Southern Vietnam) significantly alter wastewater viscosity, sludge charge distribution, and polymer dissolution rates. Standard polyacrylamide formulations frequently suffer from rapid thermal degradation or incomplete hydration. Oubo Chemical’s modified Cationic Polyacrylamide (CPAM) formulations are tailored with enhanced thermal stability and moisture-resistant micro-granulation specifically optimized for Southern Vietnam's climatic and operational realities.
Cationic Polyacrylamide (CPAM) is a linear water-soluble macromolecular copolymer synthesized through the copolymerization of acrylamide monomers and cationic monomers such as DAC (Acryloyloxyethyltrimethyl ammonium chloride) or DMC (Methacryloyloxyethyltrimethyl ammonium chloride). Characterized by positively charged quaternary ammonium groups along its polymer backbone, CPAM operates via two primary physicochemical mechanisms: Charge Neutralization and Polymeric Bridging.
Most organic suspended solids, municipal biological sludges, and industrial dye particles carry strong negative electrostatic surface potential (measured as Zeta Potential). Upon dosing Oubo’s Cationic Polyacrylamide, the positive quaternary ammonium charges compress the electrical double layer around suspended particles, reducing repulsion forces to zero. Concurrently, the high-molecular-weight long polymer chains adsorb onto multiple particle surfaces, building heavy, tightly bound flocs that rapidly separate from clear supernatant liquid under shear force in mechanical dewatering equipment.
