Sediment filters are the first step that many people take in their search for clean, quality tap water and are oftentimes all that is necessary to treat the water. To properly implement a sediment filter treatment, care must be taken in selecting the proper level of filtration for your particular water problem.
Many people assume that going to the sediment filter with the smallest mesh immediately is their best bet, because it will catch the most sediment. This approach is often a bad idea for specifically this reason. Using a sediment filter with a fine mesh with significantly larger sediment will cause the filter to clog prematurely, leading to a drop in pressure across the sediment filter.
Sediment filter cartridges are inexpensive and most fit universal housings, so it’s best to start with a higher mesh sediment filter cartridge and test to see what your best solution is. Often, it’s best to use a multi-stage sediment filtration process, wherein a larger mesh sediment filter cartridge or series of sediment filters take out large particles; then a finer mesh sediment filter cartridge acts as a finisher.
For applications in which sediment filter cartridges are soiled quickly it’s recommended to step up to a backwashing sediment filter. A backwashing sediment filter removes the need to replace cartridges by cleaning its media bed on a timed schedule. Using different media for sediment filtration can increase or decrease the mesh diameter of a backwashing sediment filter.
In circumstances in which there is iron or manganese present in the water, it’s often more efficient to use a backwashing, oxidizing filter such as a Terminox ISM to treat the water. The Terminox ISM media also acts as a sediment filter down to 20 microns, so when a Terminox is used it is rarely necessary to have a separate sediment filter in line as well.
As always remember to have your water tested. You must always start with water quality and then move on to the water filtration equipment. Many people mistakenly start with the water filtration equipment instead of the water quality. You can’t take a “cookie cutter” approach to treating water.
