Tannin extract, known in Chinese as "栲胶" (kǎo jiāo), is used in water treatment for its natural coagulating and flocculating properties. Here's an overview:
Key Characteristics
Source: Derived from plant materials like oak bark and chestnut.
Appearance: Typically a brown, powdery substance.
Solubility: Soluble in water, often used in aqueous solutions.
Applications in Water Treatment
Coagulation: Tannin gum neutralizes charges on suspended particles, enabling them to clump together.
Flocculation: These clumps, or flocs, grow larger and can be more easily removed from the water.
Benefits
Eco-Friendly: Offers a greener alternative to synthetic chemicals.
Effectiveness: Reduces turbidity and removes organic matter efficiently.
Process
Addition: Tannin gum is added to the water, interacting with impurities.
Mixing: The water is agitated to promote floc formation.
Separation: Flocs are removed through sedimentation or filtration.
Tannin gum is particularly useful in treating industrial wastewater and improving the quality of drinking water, offering an effective and sustainable solution.
