Quality

Filter sheets produced in a controlled environment. Manufactured according to ISO 9001:2015 certified Quality Management System.

 

Suggested Operating Instructions

Handling during installation 

  1. Place sheet over support plate of the plate and frame filter
  2. For filters with manual tightening device: moisten filter sheets then tighten
  3. For filters with hydraulic tightening device: tighten up to filter pre-pressure of 30-35 bar (432-507 psi). Rinse the filter with warm water at ambient temperature in a forward flow direction with at a flow of at least 50 L/m2
  4. Control and adjust the filter to a pre-pressure of 30-35 bar (432-507 psi) and sterilize

 

Rinsing post filtration 

  1. Flush with water at a temperature of 50-55 °C (122-131 °F)
  2. Flow in the forward direction: should be at least nominal filter output
  3. Counter pressure of 0.5 bar (7.25 psi)
  4. Duration: 10-15 minutes or until the rinse water is clear.

 

Hot water flushing 

  1. Water temperature: >85 °C (185 °F)
  2. Flow in the forward direction: minimal nominal filter output
  3. Counter pressure of 0.5 bar (7.25 psi)
  4. Duration: until a temperature of at least 85 °C (185 °F) is achieved on the outlet side. Allow the filter to stand for at least 30 minutes with hot water. Open the vent valve on the filter inlet side.

 

Steaming 

  1. Steam temperature: max 121 °C (250 °F), low-pressure steam
  2. Duration: 20 minutes
