Filtration methods are widely used in industrial and commercialapplications, with cartridge filters and media filters being two commontypes. They all have their pros and cons.
Cartridge filters use pre-packaged filter elements that are easy to installand replace. Cartridge filters are therefore very handy and good forapplications where filters need to be changed on a regular basis.Cartridges, however, tend to have a lower dirt loading capacity and aremore expensive to run due to frequent replacement.
Media filters use loose filter media, such as quartz sand and anthracite,contained in larger vessels. They can hold more dirt before they have tobe cleaned. Media filters also allow for better filtration because themedia can be carefully graded.
Media filters, however, need periodic cleaning and media replacementthat requires draining the filter vessel. They also occupy more space.
Overall, cartridge filters are suited for applications where ease ofmaintenance is more important than dirt loading capacity. Media filtersare better suited to larger volumes of water, or where a higher level ofcontaminant removal is required. Some systems use the strengths ofboth, using cartridges for pre-filtration and media for fine filtration. Theright choice is dependent on application needs, flowrates andcontaminant levels. Optimisation is choosing the right filter andmaintaining it regularly.
