In the era of intensifying global water scarcity and rigorous environment regulations, industrial and municipal organizations are shifting from linear water consumption models to highly efficient closed-loop water reclamation networks. Successful water reclamation depends fundamentally on the optimization of solid-liquid separation phases. Advanced macromolecular chemistry—specifically high-performance coagulants and flocculants—forms the technological bedrock of these separation processes.
As a premier developer and manufacturer, Wuxi BS Water Treatment Chemicals Co., Ltd. has spent over 27 years perfecting chemical formulations that reduce total dissolved solids (TDS), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), and suspended particles. By stabilizing colloidal suspensions and driving high-velocity settling dynamics, our technologies empower systems such as Membrane Process Pretreatment, biological reactors, and municipal clarifiers to operate at peak thermodynamic and volumetric efficiency.
Engineered for rapid sedimentation, heavy impurity filtration, and precise molecular weight distribution to resolve critical turbidity challenges.
To achieve high-efficiency solid-liquid separation, water treatment plants rely on a dual-mechanism sequence: charge neutralization followed by polymeric bridging. In untreated wastewater, suspended organic materials, silts, and bacteria carry negative surface charges (measured as negative Zeta Potential). These electrostatic repulsive forces prevent the particles from colliding and coalescing, keeping them permanently suspended.
When products like Polyaluminum Chloride (PAC) or Aluminum Chlorohydrate (ACH) are dissolved in water, they release highly charged aluminum complexes. These trivalent cations ($Al^{3+}$) adsorb onto negatively charged colloidal particles, reducing the net surface charge (Zeta potential closer to zero). With electrostatic repulsion neutralized, Van der Waals attraction forces take over, causing the particles to form micro-flocs.
Once micro-flocs form, high molecular weight polymers like Polyacrylamide (PAM) are introduced. The long polymer chains attach to multiple micro-flocs simultaneously, linking them into large, heavy, macro-floc aggregates (known as "flocculation"). This massive expansion in cluster size increases the sedimentation rate exponentially, according to Stokes' Law, clearing the liquid in minutes.
