Accessories&Filters

Water purification equipment accessories refer to a variety of auxiliary components to support the normal water purification system, they help water quality operation treatment, connection, control water flow, etc. Common water purification equipment accessories include the following:

• Pressure drums: A common accessory for storing purified water, especially in reverse osmosis water purification systems. It can temporarily store purified water to ensure that users get enough drinking water in a short time.
• Water pump: In a reverse osmosis (RO) water purifier, the water pump is used to provide enough pressure to help the water pass through the reverse osmosis membrane. For areas with low water pressure, pumps are necessary.
• Hose: Hose is responsible for connecting each water purification module to ensure the smooth and sealing of the waterway.
• Filter bottle and cartridge shell: The container in which the filter cartridge is installed to protect the filter cartridge and allow water to pass through the filter cartridge for filtration.
• Valve and controller: including inlet valve, drainage valve, pressure control valve, etc., can regulate the water flow, control the water purification process, and maintain the stable operation of the system.
• Flush valve: Some water purification equipment equipped with backwash valve, used to clean the filter element or diaphragm, extend the service life of the equipment.
• TDS monitor: Used to measure the total dissolved solids (TDS) content of water, assess the purification effect of water and whether the water quality is up to standard.

The filter element of water purification equipment is one of the core components of water purification equipment, which is responsible for achieving precision, filtration and odor of water quality. Different types of filters have different filtration capabilities and functions, common filter types include:

• Common filter type: PP cotton filter (multi-layer melt-blown filter)
• Function: Primary filtration, remove large particulate matter in water, such as sediment, rust, suspended matter, etc.
• Features: cheap, generally as the first filter, to protect the subsequent filter element.
• Activated carbon filter element
• Function: Adsorption water odor, residual chlorine, pesticide residues, organic matter, etc., improve the taste of water.
• Features: Divided into granular activated carbon and compressed activated carbon filter, compressed activated carbon is usually better filtration effect.
• Ultrafiltration membrane filter element
• Function: Through the principle of physical filtration, filter out the bacteria, viruses and colloids in the water, and retain a safe water source.
• Features: The aperture is small, usually can filter out more than 0.01 micron particles, suitable for large and safe water sources.
• Reverse osmosis membrane (RO membrane)
• Function: Reverse osmosis membrane is the highest precision filter element, which can remove heavy metals, bacteria, viruses, inorganic salts and organic matter in water, leaving almost only pure water molecules.
• Features: High filtration accuracy (aperture is about 0.0001 micron), requiring precision pump assisted pressure filtration. RO membrane is the core filter element for purifying water.
• KDF filter element
• Function: It is used to remove heavy metals from water and inhibit cell proliferation. It is often used in combination with activated carbon to improve water purification effect.
• Features: Composed of copper-zinc alloy, it eliminates harmful metal ions through REDOX reaction.
• Resin filter element:
• Function: Remove calcium and magnesium ions in water, soften water quality, and prevent scale.
• Features: Common in water softener, suitable for hard water areas.
• Mineralized filter element:
• Function: Add the right amount of purified water again, improve the taste of water, and increase the content of trace elements.
• Features: Often used in some water purification equipment that requires mineralized water.

Replacement and maintenance of filter element:

• The filter element has a limited service life and will accumulate, silt or fail after prolonged use, so it needs to be replaced regularly. Different types of filters have different replacement cycles:
• PP cotton filter: generally 3-6 months to replace once.
• Activated carbon filter element: Replace once every 6-12 months, depending on the water quality.
• Ultrafiltration membrane: Usually lasts 1-2 years.
• Reverse osmosis membrane (RO membrane) : The duration is usually 2-3 years, but it should be checked regularly according to the water quality and frequency of use.

The importance of water purification equipment accessories and filter elements:

• The importance of accessories: Good accessories can ensure the normal operation of water purification equipment, reduce the possibility of water leakage or system failure, and improve the service life of the equipment.
• The importance of the filter element: the filter element determines the purification effect of the water purification equipment, and the choice of the appropriate filter element and regular replacement is the key to ensure the safety of water quality and the long-term operation of the equipment.

In summary, the water purification equipment accessories and filter element together constitute the core part of the water purification system, accessories are responsible for supporting the normal operation of the system, and the filter element is responsible for filtering all kinds of impurities in the water to ensure the health and safety of the water after purification.
