Installation and Use of Cartridge Filter

Compared to bag filters, cartridge filters are devices that utilize filter cartridges for filtration. They are widely used in solid-liquid separation in industries such as food, chemical, electroplating, and printing and dyeing. The number of cartridges inside the filter is variable, ranging from 1 core, 3 cores, 5 cores, 7 cores, 9 cores, 11 cores, 13 cores, 15 cores, etc., depending on the requirements of the working conditions.

Below are the steps for installing a cartridge filter:

1.Thoroughly clean the filter housing.

2.Connect the inlet and outlet of the housing to the filtration system pipeline, paying attention to the direction to ensure that the filter cartridge is in the state of outer inlet and inner outlet.

3.Open the plastic bag at one end of the cartridge, check if the O-ring is intact and in place.

4.Moisten the O-ring and cartridge seat insertion hole with a suitable wetting agent (such as water).

5.Hold the cartridge near the end with the O-ring, and insert the cartridge completely into the cartridge seat insertion hole vertically.

6.After inserting all the cartridges, remove the cartridge packaging bag, then fix it with a pressure plate, and install the metal cover.

7.Open the vent valve at the top of the cartridge filter housing.

8.Slightly open the inlet valve to allow liquid to enter the housing until it overflows from .the vent valve at the top of the housing, then close the vent valve.

9.Slowly adjust and open the downstream outlet valve until fully open.

10Slowly adjust and open the inlet valve of the cartridge filter until fully open. At this time, the pressure drop between the upstream and downstream of the filter is 0.02Mpa (initial pressure drop under determined flow rate).

Precautions for Use:

1.Avoid pressure shocks when operating the cartridge filter, and do not apply reverse pressure.

2.If the pressure drop between the upstream and downstream of the filter is greater than 0.3Mpa or the flow rate significantly decreases, consider replacing the cartridge.

3.If the filter is temporarily not in use, do not let the cartridges dry out. Instead, immerse them in a suitable sterilizing solution (or inject such a solution into the housing). Before reuse, rinse the sterilizing solution thoroughly.

4.If steam sterilization is to be performed on the cartridge filter, the condensate water in the steam pipeline must be drained first. The steam pressure should not exceed 0.1Mpa, and the pressure drop between the upstream and downstream of the filter should not exceed 0.015Mpa. If steam sterilization is to be performed on wet cartridges, the liquid absorbed by the cartridges should be drained using clean compressed air before steam sterilization to prevent damage to the cartridges.
