When choosing the right filtration system for your needs, you may haveto decide between a filter material driven filter and a cartridge filter. Eachoption has its pros and cons, so it's important to understand theircharacteristics before making a choice.
In a media filter, a filter driven by filter material, a bed of filter media suchas sand, anthracite, or activated carbon removes impurities from water.As the water flows through the media the particles are trapped within thebed. The filters are renowned for their high flow rates, effective filtrationand long service life. They are often used in larger applications such aswater treatment plants where large volumes of water are required tobeBoth options have their advantages and disadvantages, so it isimportant to know their characteristics before you choose.
In contrast, a cartridge filter is made up of a replaceable cartridge whichcontains a filter element that traps contaminants as water passesthrough it. Cartridge filters come in various materials and styles, such aspleated, string-wound, and carbon filters. They are generally easier toinstall, maintain and replace than media filters. Cartridge filters aregenerally used in residential and smaller scale applications such as pointof use water filtration systems and aquarium filters.
There are a number of considerations in choosing between the twooptions. First, the specific filtration requirements of your application areimportant. If you want to filter out fine particles or specific contaminants,a cartridge filter with the right filter element might be a better choice.However if you need high flow rates orCartridge filters are available in arange of materials and configurations including pleated, string-woundand carbon filters. They are generally easier to install, maintain andreplace than media filters.
Secondly, the available space for the filtration system has to be takeninto consideration. Cartridge filters are smaller than media filters andcan fit into tight spaces, while media filters are bigger and take up morespace.
Furthermore, the assessment of each option shall include maintenanceand operational costs. Cartridge filters usually have to be changed moreoften, which can increase the cost over time. Media filters however, mayrequire backwashing on a periodic basis or media replenishmentdepending on the media used in the filter.
