In the water purification industry, there are various types of materials used for drinking water purification, each with its unique characteristics and functions. Below are some of the main materials commonly used, along with their properties and functions:
PP Cotton Filter Cartridge (Polypropylene Filter Cartridge)
Characteristics:
- Made of polypropylene fibers with a porous structure.
- Typically cylindrical and white, with varying pore sizes.
Functions:
- Primarily used to remove large particles such as sediment, rust, and suspended solids.
- Acts as the first line of defense in a water purification system, protecting subsequent filters.
Activated Carbon Filter Cartridge
Characteristics:
- Made from coconut shell, coal, or wood-based activated carbon, with high adsorption capacity.
- Contains numerous micropores on its surface to adsorb various pollutants.
Functions:
- Removes chlorine, odors, organic compounds, and some heavy metals.
- Improves the taste and odor of water.
Reverse Osmosis Membrane (RO Membrane)
Characteristics:
- Made of polymer materials with extremely small pores (approximately 0.0001 microns).
- Requires water pressure to function.
Functions:
- Removes dissolved salts, heavy metals, bacteria, viruses, and other microscopic particles.
- Provides high-purity drinking water.
Ultrafiltration Membrane (UF Membrane)
Characteristics:
- Made of polymer materials with larger pores than RO membranes (approximately 0.01 microns).
- Operates under natural water pressure without requiring additional pressure.
Functions:
- Removes bacteria, viruses, colloids, and large organic molecules.
- Retains beneficial minerals in water.
Ceramic Filter Cartridge
Characteristics:
- Made from natural diatomaceous earth, fired to create a microporous surface.
- Can be cleaned and reused.
Functions:
- Removes bacteria, parasites, and suspended solids.
- Suitable for outdoor or emergency water purification.
KDF (Kinetic Degradation Fluxion) Filter Media
haracteristics:
Made of high-purity copper-zinc alloy, removing pollutants through electrochemical reactions.
Functions:
- Removes chlorine, heavy metals (such as lead and mercury), and inhibits bacterial growth.
- Often used in combination with activated carbon to enhance filtration efficiency.
Ion Exchange Resin
Characteristics:
Made of polymer materials containing exchangeable ion groups.
Functions:
- Removes calcium and magnesium ions to soften water.
- Can also be used to remove heavy metal ions.
Ultraviolet (UV) Sterilization Lamp
Characteristics:
- Uses ultraviolet light to kill microorganisms.
- Does not alter the chemical properties of water.
Functions:
- Kills bacteria, viruses, and other pathogens in water.
- Typically serves as the final barrier in a water purification system.
Nanofiltration Cartridge
Characteristics:
Uses nanotechnology to create filter cartridges with pore sizes between ultrafiltration and reverse osmosis.
Functions:
- Removes organic compounds, bacteria, viruses, and some heavy metals.
- Retains beneficial minerals.
Mineralization Cartridge
Characteristics:
Contains natural minerals such as maifan stone and coral sand.
Functions:
- Adds beneficial minerals and trace elements to water.
- Improves the taste and nutritional value of water.
Summary
Different water purification materials have their unique characteristics and functions. In practical applications, multiple filter cartridges are often combined to achieve optimal purification results. For example, a complete household water purification system may include a PP cotton filter cartridge, activated carbon filter cartridge, RO membrane, and UV sterilization lamp to ensure the removal of various contaminants and provide safe, healthy drinking water.
