A cartridge filter is a piece of tubular filtration equipment that can be used across various industries for an array of filtration requirements. A cartridge is encased within a housing or a casing and used to remove unwanted particles, pollutants, and chemicals from liquids. The cartridge is exposed to water, liquid, or solvent that needs filtration, as it flows inside the housing and passes through the filter element. Cartridge filters can also remove submicron particulates.
How To Clean Industrial Filter Cartridges?
Filter cartridges are used in many industrial applications to trap contaminants and solid waste. These liquid filter cartridges must be replaced when they reach their pre-set differential pressure.
When To Replace A Filter Cartridge?
It is important to know when to replace your filter cartridge. The cartridges may come with a general guideline that suggests the number of days it will work – for example, every 30 days or every 45 days based on its dirt holding capacity. However, the number of days a cartridge will last also depends on the concentration of contaminants in the liquid.
When your pressure differential reaches a pre-set value – say 10psi, you know that the cartridges are clogged and need replacement.
Here is a step-by-step how-to guide to properly and safely replace your liquid filter cartridges!
Shut down the system and let it depressurize.
Open the air vent valve and the drain.
Clean the drain valve
Remove the housing lid.
Remove wing nuts and the alignment plate.
Carefully remove the springs from the top of each cartridge filter. Make sure that the spring does not fall into the housing.
Carefully pull out the cartridges.
Check the housing for any signs of corrosion or dirt residues. Clean the housing if required.
Remove the protective covering of your new cartridge filters and fit them inside the housing.
Handle your cartridges carefully and place them in housing using the alignment plate.
Once all cartridges are in place, reinstall the springs, alignment plate, and wingnuts.
Make sure all these fitments are in good condition and securely installed in place.
Clean and lubricate the O ring and then replace the housing lid.
Screw the housing lid into place.
Close the drain valve
Purge any air in the system by running water through the filter.
Close the air vent valve
