1. Screen Filtration
1.1 Principle: Using a screen to block larger suspended and floating solids in wastewater, allowing only smaller particles and water to pass through.
1.2 Application: Domestic and industrial wastewater treatment
1.3 Process Flow: Pre-treatment stage
1.4 Function: Intercepts large particles of various sizes
2. Sand Filtration
2.1 Principle: Using sand as a filter medium, the wastewater flows through the sand layer, and small particles and suspended solids are trapped in the pores of the sand, clarifying the water.
2.2 Application: Drinking water and reclaimed water treatment
2.3 Process Flow: Further advanced treatment of wastewater
2.4 Function: Removes silt, rust, and other large suspended particles, reducing water turbidity.
3. Fiber Filtration
3.1 Principle: Using a filter material made of fibers, suspended solids and colloids are attached to the fiber surface or trapped in the pores formed by the interwoven fibers, thus removing impurities and purifying the wastewater.
3.2 Application: Industrial wastewater, such as textile and dyeing wastewater, and paper mill wastewater
3.3 Process Flow: Advanced treatment
3.4 Function: Removes residual fine fibers, dye particles, and other impurities from wastewater
4. Activated Carbon Filtration
4.1 Principle: Uses physical adsorption to remove organic matter, heavy metal ions, and odor-causing substances from wastewater, achieving advanced purification.
4.2 Application: Reclaimed water or domestic wastewater with high water quality requirements
4.3 Process Flow: After advanced or biological treatment
4.4 Function: Removes trace amounts of organic matter and odors from water
5. Membrane Filtration
5.1 Principle: Uses a membrane with selective permeability to separate substances of different particle sizes, effectively separating everything from large suspended solids to ions.
5.2 Application: Seawater desalination, brackish water desalination, and zero-discharge treatment of various industrial wastewater
5.3 Process Flow: Advanced treatment
5.4 Function: Provides high-quality reclaimed water for urban landscaping and industrial use
