Types of filter cartridge price reverse osmosis water

Reverse osmosis water filters are commonly used in water purification systems. Their functions mainly include removing minerals, organic material, and bacteria from water. As reverse osmosis filter cartridges are the key components in the water filtration process, they should be designed to be functional, efficient, and safe.

The first main type of reverse osmosis filter cartridge is the particle and chlorine removal filter, which is also known as an activated carbon filter. This is the pre-filter of the reverse osmosis cartridge. Its function is to remove large particles, such as sand, silt, and chlorine, before the water passes through the RO membrane. The second type is the reverse osmosis membrane filter itself. It is usually made of thin-film composite (TFC) or polyamide material. The semi-permeable membrane allows only water molecules to pass through while rejecting larger molecules, including dissolved salts and virtually all contaminants. The water permeating the membrane collects as RO water. The last type of reverse osmosis filter cartridge is the post-mineralization filter. Its function is to add essential minerals back into the water to improve the taste. Additionally, some post-filters also include UV bulbs that can effectively kill any bacteria remaining in the water.

Normally, reverse osmosis water system filters are made with high-quality plastic housings. The size of an RO filter cartridge usually includes a length of 250mm and a big diameter of 15cm. The small size makes it easy to install into a typical kitchen cabinet.

Specifications and Maintenance

General RO filter cartridge specifications buyers need to know include the membranes' material, size, flow rate, and waterborne contaminants they can treat.

• Membrane Material: Both thin-film composite (TFC) and cellulose acetate (CA) membranes are spiral-wound plastic sheets. However, they differ in material makeup. TFC membranes, which contain a polymer, are prized for their ability to eliminate most impurities. Because they are less permeable and more durable, TFC membranes are ideal for municipal and well water. CA membranes work well with clear water sources that contain little to no dissolved matter.
• Size: Household reverse osmosis filter cartridges are usually 2 to 3 inches in diameter, with lengths of 10, 12, or 14 inches. Larger industrial size filters can be as large as 8 inches in diameter and 40 inches long. The larger the filter, the more water it can purify in a turn.
• Flow Rate: Flow rates for residential RO filter cartridges typically range between 50 and 300 gallons per day (GDP). Business buyers need to get the exact flow rate from the supplier's catalog. They should also ask how to adjust the flow rate by changing membrane sizes.
• Waterborne Contaminants: Reverse osmosis cartridges can have any of the following water contaminants listed: fluoride, radon, arsenic, dissolved solids, lead, mercury, calcium, sodium, and hazardous pesticides, including herbicides like atrazine.

Maintenance:

Reverse osmosis filter cartridges degrade with use. Contaminants and impurities can build up on the membrane's surface, clogging it and restricting water flow. In addition, bacteria may gather on the filter material. Therefore, routine cleaning is necessary to improve the cartridge's life span and ensure it provides pure drinking water.

General maintenance tips include:

• Users should flush the membrane every month. Flushing involves sending water through the membrane to remove contaminants that have settled on it. The flushing process prevents clogging and bacterial growth.
• Users should check the pump pressure each month and ensure it is between 50 to 70 psi. The pump pressurizes water to enable the filter to remove impurities.
• Users should clean the RO storage tank every six months by flushing it with bleach and a solution of baking soda. This process removes bacteria and algae growing in the tank.
• Users should check the tubing and connections every three months and ensure there are no leaks or cracks. Sealing exposed areas can prevent leaks.
• Replace the pre-carbon filter every 12 months and the post-carbon filter every two years. The carbon filters usually clog and release bad odor when used to filter water.

Usage scenarios of reverse osmosis filter cartridges

Reverse osmosis filter cartridges are crucial to commercial places such as food and beverage companies, laboratories, and pharmaceutical factories.

• Food and beverage production

  Food and beverage companies need clean water as an essential raw material. Water is the primary component of beverages such as juices, soft drinks, beer, and dairy products like cheese and yogurt. Filter cartridges offer pure, unadulterated water as a vital ingredient, ensuring flavors' integrity, safety, and quality.

  Additionally, filter cartridges remove impurities that can dull the equipment, extending their lifespan. This not only reduces maintenance expenses but also helps to optimize resource utilization, allowing food and beverage enterprises to serve more customers and increase production efficiency.

• Laboratories

  Clean and purified water is essential in laboratories for experiments, analyses and reagent preparation. Impurities in unfiltered water can skew experimental results, leading to inaccurate conclusions and ineffective research.

  Using reverse osmosis filter cartridges to obtain purified water helps ensure the precision and reliability of laboratory work, supporting scientists in their pursuit of excellence and innovation.

• Pharmaceutical factories

  Pharmaceutical factories require high-purity water for drug production and rinsing of equipment and containers. Reverse osmosis filter cartridge produce purified water that meets stringent quality standards, helping to ensure the safety and efficacy of medications.

  Additionally, reverse osmosis systems can eliminate microbiological contaminants, supporting pharmaceutical factories in their quest to safeguard public health.
