Under the right pressure, the cartridges filter the water and let clear water through. Water filter cartridges generally last up to a year, depending on the water used in your home, business or industrial plant.<\/p>\n<p>Cartridges trap unwanted particles and contaminants until the filter is saturated, at which point it must be replaced. Cartridge filters are used mainly in wastewater treatment plants and drinking water treatment plants. Other industrial applications include:<\/p>\n<ul>\n<li>chemical processing<\/li>\n<li>oil and gas refineries<\/li>\n<li>automotive manufacturing<\/li>\n<li>electronics manufacturing<\/li>\n<li>metallurgy and machining<\/li>\n<li>food and beverage processing.<\/li>\n<\/ul>\n<h2>Components of a cartridge filter<\/h2>\n<h3>1. Cartridge<\/h3>\n<p>This is the main element of the filter, capturing the impurities or contaminants in the liquid or gas. Depending on the application, it is made of polyester, cellulose, polypropylene, ceramic or activated carbon.<\/p>\n<p>Common types of filter cartridge include:<\/p>\n<ul>\n<li>pleated polypropylene cartridges<\/li>\n<li>spun polypropylene cartridges<\/li>\n<li>pleated PTFE cartridges<\/li>\n<li>resin cartridges<\/li>\n<li>stainless steel cartridges<\/li>\n<li>wound polypropylene cartridges.<\/li>\n<\/ul>\n<h3>2. Housing<\/h3>\n<p>The housing is the outer container that holds the cartridge in place. It is made of durable material to withstand the pressure of the fluid passing through the filter.<\/p>\n<h3>3. O-rings<\/h3>\n<p>O-rings, or gaskets, create a tight seal between the housing and the end caps, preventing leaks so that the liquid or gas passes through the filter medium.<\/p>\n<h3>4. Inlet and outlet ports<\/h3>\n<p>The inlet port lets the unfiltered liquid or gas into the housing, and the filtered fluid leaves through the outlet port.<\/p>\n<h3>5. End caps<\/h3>\n<p>The end caps secure the ends of the cartridge, ensuring that the fluid passes through the filter medium and that the cartridge sits correctly in the housing.<\/p>\n<h2>What do cartridge filters remove?<\/h2>\n<p>Depending on their micron rating and filter medium, <a href=\"https:\/\/keikengroup.com\/en\/news\/cartridge-filters-for-water-treatment\/\">cartridge filters<\/a> can effectively remove a range of impurities, including:<\/p>\n<ul>\n<li>sediment and particles<\/li>\n<li>oil and grease<\/li>\n<li>suspended solids<\/li>\n<li>pollen and allergens<\/li>\n<li>micro-organisms and bacteria (with suitable ratings)<\/li>\n<li>chemicals and contaminants (with suitable media)<\/li>\n<li>rust and corrosion products.<\/li>\n<\/ul>\n<h2>Signs that it is time to replace the filter<\/h2>\n<p>Sometimes it is easy to tell that a filter is no longer working as it should: the water may smell or taste different, or slimy residue may build up around the edges of the cartridge. If you notice any of these signs, call a professional.<\/p>\n<p>A common myth is that a filter needs replacing only when the water flows more slowly. That is not always the case: the water can still flow at full pressure while the filter is no longer doing its job.<\/p>\n<p>A maintenance contract for your filtration system helps keep it working effectively.<\/p>\n<h2>How often should the cartridge be replaced?<\/h2>\n<p>Replacement frequency depends on your water supply and the type of filtration system. Most systems come with a suggested cartridge replacement schedule. If your sediment filter clogs every three months, plan replacements accordingly, and if the water starts to taste bad, replace the cartridges without delay.<\/p>\n<p>Do not keep using the water until it smells or tastes bad. If three months is too long, change the cartridge every two months. One risk of not changing it is bacterial growth, which can be released into the drinking water.<\/p>\n<p>If you use <a href=\"https:\/\/keikengroup.com\/en\/news\/cartridge-filters-for-water-treatment\/\">cartridge filters<\/a> in a commercial application such as a restaurant or caf\u00e9, serve your customers well by maintaining your water filtration system properly.<\/p>\n<h2>Key points<\/h2>\n<p>KEIKEN offers a wide selection of cartridge filters to suit the specifications of any project.
