Anyone familiar with cartridge filters will know that they come in a bewildering variety of types and sizes. Their relatively low capital equipment costs, ability to handle varied service flows, and minimal space requirements make them an attractive method of solving water problems.
Cartridges hold many advantages. For starters, they can be plumbed in-line to give relief to a specific problem, without the need for backwashing or waste flow handling. Maintenance becomes a periodic change-out of the cartridge per the manufacturer's prescribed frequency-an easy service scenario. At the very least, it can be a potential cartridge sale for the contractor who is willing to stock some of the replacement items and monitor the customer's use.
