FIRST STAGE

• SCR L self-cleaning filter in SAF2205 80-15
• 80 micron filtration
• Flow rate 25 mc/h

SECOND STAGE

• SCR L self-cleaning filter in SAF2205 80-15
• 20 micron filtration WITH 3D FABRIC
• Flow rate 25 mc/h

THIRD STAGE

• Melt blown polypropylene filter 9″x 40″ Cartridge diameter 2″1/2
• 5 micron filtration
• Flow rate 25 mc/h

Previously, the system consisted of an 80 micron self-cleaning filter + a 25 micron self-cleaning filter (with monofilament fabric).

The change of filtering element in the second stage, from 25 micron monofilament to 20 micron 3D has led to lengthening the life of the melt blown filter cartridges. With 25 micron monofilament fabric the filter cartridges were replaced every day, with 20 micron 3d fabric the cartridge change has gone to 4 days.

The SCR series self-cleaning filters (suction nozzles) were installed in 2009. The cleaning system had lost efficiency and in agreement with the customer we decided to insert the new washing system on the filters, replacing only the internal parts.

TECHNICAL FEATURES

• Water type: Pre-filtered sea water at 1 mm
• Maximum system flow rate: 300 mc/h
• SCR filter filtration degree: 80 microns
• Filter surface area: 0.65 sq m x 3 filters
• Use: Plate exchanger protection
• Working pressure: Approximately 0.8 bar

The paper mill requested the creation of two self-cleaning filters to protect the spray nozzles used to wash the dewatering felts. The main issue for the mill was the clogging of the nozzles, which prevented continuous paper production.

The water coming from the flotation system is divided into two lines:

1. Low-pressure line: 5 bar
2. High-pressure line: 25 bar

On the low-pressure line, with a flow rate of 90 m³/h, we installed one US filter (spray nozzles) with a filtration degree of 100 microns.

On the high-pressure line, with a flow rate of 84 m³/h, we installed one SCR filter (suction nozzles) with a filtration degree of 100 microns.

Filtration of paper mill waters is one of the most complex challenges we have encountered during our experience.

With our expertise and the collaboration of the customer, we succeeded in developing an excellent solution.

The fabrics tested ranged from a filtration grade of 20 microns to a filtration grade of 1 micron, made from polyester, polypropylene, and AISI316.

The objective of the test was to identify the best filter fabric for 20-10-5-1 micron for our SCR L MICRON filters.
