Application of Filter Membrane in the Drinking Water Industry

The filter membranes are widely used in the drinking water industry.

Its advantages are as follows:
1. No coagulant is required;
2. Simple automatic operation and easy unmanned management;
3. The water plant occupies less land;
4. Low maintenance and management costs;
5. Easy drainage;
6. It can remove suspended matter and solid matter in industrial sewage.

 

The service life of filter membranes

The membrane hole is blocked by impurities in the water, which increases the loss of water head and reduces the flow rate when the fluid passes through the membrane hole. At this time filter membranes can usually be rinsed with water so that the membrane hole to restore the original infiltration capacity.
The selection of filter membranes is the key to achieving the best filtration effect. The filter material should adapt to the different chemical properties of the filter medium. At present, the fluoroethylene membrane and the mixed fiber resin membrane are commonly used.

Features of filter membranes

1. Strong and permanent hydrophilicity;
2. High velocity;
3. High filtration accuracy;
4. Clean, no shedding, low solubility;
5. Long service life;
6. Chemical resistance, high-temperature resistance.
7. Virus and Bacteria Removal: Purpose: Specialized membranes are designed to remove viruses and bacteria, ensuring microbiological safety.
Application: Critical in producing safe drinking water by eliminating pathogens that can cause waterborne diseases.
8. Activated Carbon Membranes: Purpose: These membranes incorporate activated carbon for the adsorption of organic compounds, chlorine, and other chemicals.
Application: Reduction of taste, odor, and the removal of organic contaminants.
9. Pore Size Filtration: Purpose: Membranes with specific pore sizes are used to target specific contaminants based on their molecular size.
Application: Removal of particles, colloids, and macromolecules from water.
10. Membrane Filtration in Package Plants: Purpose: Smaller-scale package plants utilize membrane filtration technologies for small communities, remote areas, or temporary facilities.
Application: Providing clean and safe drinking water in areas where large-scale treatment facilities may not be feasible.
11. Point-of-Use (POU) and Point-of-Entry (POE) Systems: Purpose: Filter membranes are incorporated into household water treatment systems to ensure safe and clean drinking water at the tap.
Application: Used in homes, offices, and other settings to remove contaminants like sediments, chlorine, pathogens, and more.
12. Quality Control and Testing: Purpose: Filter membranes are used for analytical procedures to assess water quality and monitor treatment effectiveness.
Application: Laboratories use filter membranes for various water quality testing methods, such as turbidity measurement, particle counting, and microbiological analysis.

Filter membranes are a cornerstone of water treatment processes, enabling the production of safe and high-quality drinking water for communities around the world. Their versatility and effectiveness make them indispensable tools in the drinking water industry.
