A common method for removing particles and pollutant compounds from water is filtering through cartridge filters. These filters are mostly employed in wastewater treatment plants, and in pre-treatments in desalination and drinking water treatment plants.

Let’s review how to replace cartridge filters that are used in water treatment.

How does cartridge filter work?

Pressure is used to create the filtering, which allows the passage of clear water while trapping particles and undesired contaminants, until the filter becomes saturated and needs to be replaced with a new one.

The pressure differential between the inlet and exit pressures is used to determine the saturation of the same. Since, the energy cost of continuing increases when this pressure difference reaches a limit defined in the operation, the substitution is made.

Depending on the specific project, the container or casing housing these filters, may be made of carbon or stainless steel or GRP. The food sector, chemical processing, as well as the final phase of protection for reverse osmosis membranes, potable water purification, etc. are some of the industrial applications of cartridge filters.

Benefits of cartridge filters

Some benefits include:

• They take up less room

• Financial

• You have a pore filtration option

• Very powerful

• Low-maintenance

• Have strong chemical resistance and good corrosion resistance

When to replace cartridge filters used in water treatment?

Knowing when to change your filter cartridge is crucial. Depending on how much filth they can retain, the cartridges may come with a basic guideline that specifies how many days they should operate, such as every 30 or every 45 days. However, the quantity of pollutants in the liquid and the length of time a cartridge will last are both the factors.

You can tell that the cartridges need to be replaced when the pressure differential reaches a preset level, such as 10 psi.

Here is a step-by-step tutorial on how to replace your liquid filter cartridges, in an appropriate and secure manner.

1: Turn off the system and let the pressure drop.

2: Open the drain and the air vent valve.

3: Sanitise the drain valve.

4: Take the housing lid off.

5: Remove the alignment plate and wing nuts.

6: Remove the springs with extreme caution from the top of each cartridge filter.

7: Check to make sure the spring won't slam into the housing.

8: Pull the cartridges out slowly.

9: Look for any corrosion or dirt stains on the housing. If necessary, clean the housing.

10: Your replacement cartridge filters should be placed within the housing, after removing the protective covering.

11: Use the alignment plate to properly place your cartridges in the housing.

12: Reinstall the springs, alignment plate, and wing-nuts when all the cartridges have been installed.

13: Ensure that each of these fittings is in good working order and is firmly affixed.

14: Replace the housing lid after cleaning and lubricating the O-ring.

15: Place the housing lid with a screw.

16: Shut off the drain valve.

17: Run water through the filter to remove any air from the system.

18: Shut off the air vent valve.
