Cleaning* 1. Turn off and lock out any pumps and/or
equipment connected to the strainer process line.
2. Ensure that all pressure has been relieved from the system the strainer is installed on. 3. Close any available blocking/isolation valves. 4. Remove and disassemble the strainer internals. 5. Remove any mesh overlay, perforated overlay, or filter tube if present.
Figure 4: COP Parts Washer Cleaning
a. The perforated overlay can be cleaned and reused using a clean-out-of-place (COP) parts washer or other automated system as described in step 7. b. The mesh overlay can be cleaned. c. The filter tube must be discarded after each use. 6. Use a hose to spray the insert off with water to remove loose debris.
7. Clean the insert and other internals using a clean-out-of-place (COP) parts washer or other automated system running at an adequate temperature, chemical concentration, and amount of time to remove all soil residue. If automated cleaning is not available, manually clean soil residue off the element using a scrub device, water source, chemical, and gloves. 8. Rinse with an appropriate water supply and inspect all parts for cleanliness and damage. 9. Reassemble the strainer as described in the assembly section.
*These are recommended cleaning instructions only. Follow any plant sanitation standard operating procedure (SSOP) that your facility may have in place.
A tri-clamp cap can be attached to the strainer body, which can then be cleaned-in-place (CIP) if desired during COP of the strainer element and perforated overlay.
Maintenance During normal disassembly, cleaning, and reassembly, inspect the key areas of the strainer that may require maintenance: 1) Soil. Inspect for soil particulates or foreign matter caught in the element. Remove as necessary. 2) Tri-Clamp Gasket / O-Ring. Inspect for cuts, abrasions, tears, holes, deformities, or other visible damage. Replace as necessary or no longer than recommended on an annual basis. 3) Element. Check for bent components, abnormal holes, or other wear and tear or damage. Replace as necessary. 4) Perforated Overlay (if applicable). Check for bent components, abnormal holes, or other wear and tear or damage. Replace as necessary. 5) Mesh Overlay (if applicable). Inspect for tears or other damage. Replace as necessary or no longer than a recommended monthly basis. Higher mesh sizes (finer mesh) may require more frequent replacement. 6) Filter Tubes (if applicable). Inspect for tears or other damage. Filter tubes are considered “single - use” and should be replaced between each production run and/or cleaning procedure.
Remove and clean the strainer element at least once per shift. More frequent removal and cleaning may be required with heavier soils.
