Industrial Services

Filter Cleaning

We offer a comprehensive and tailor-made filter cleaning service. Our filter cleaning service is designed around the process fluid, the contamination and the materials of construction of the filter to remove unwanted materials leaving the filter ready for re-insertion into process.

Some examples of filter contaminants we have removed include:

Polymers (e.g.: polyester, polycarbonate, cellulose)
Speciality Polymers (e.g.: PEEK, PI, PAN precursor for carbon fibre)
Oil (e.g.: transformer oils, hydraulic oils, petroleum oils)
Solvents (e.g.: toluene, ethanol, propanol)
Catalysts (e.g.: vanadium based, nickel based, FCC)
Filters and Additives (e.g.: titanium dioxide, monomers and pre-polymers, barium based)
Process Contaminants (e.g.: water scale, rust)

We also undertake dismantle and reassembly of filter bundles, and complete filter units. This provides customers a range of different options to choose from which are suitable to their specific process requirements. Our filter cleaning service is enhanced by our filter integrity testing service allowing parts to be tested against manufacturing data to qualify them suitable for re-use.

Filter Cleaning

Filter Integrity Testing

Filter integrity testing is important to ensure filters are suitable for use, especially if the filters have been cleaned. All data gathered during filter integrity testing is logged onto our database allowing us to track performance across successive cleaning cycles.

PPSL offers a range of different tests to determine filter integrity. The simplest of these is Initial Bubble Point. This test indicates the largest hole in the media, and is a good determinator of suitability for re-use. The measured Bubble Point can be compared to manufacturers data and so filters can then be easily qualified as Pass or Fail.

The next test used is the Wetted Air Flow test, and this is an extension of the Bubble Point test. This test gives an indication of the mean pore size of the filter. This Flow test can be enhanced by our skilled operators with a visual check during the Flow test to assess the overall flow performance of the filter and highlighting any untoward flow characteristics.

Weight check is also performed on filters. The weight of the cleaned filter is compared to the base weight of a new filter allowing us to assess that all contamination has been removed from the filter.

Differential Pressure Testing can also be performed. This test can be undertaken using the medium of air or water, and is undertaken to describe the differential pressure across the filter at different flow rates. The measured performance can be graphed and compared to manufacturers data to determine suiability of filter use.

Benchmark testing, i.e. the testing of filters before use, is very important to provide sufficient data to compare cleaned filters to. Benchmark testing also provides customers with data on their filters before initial use. We always recommend customers send their new filters to PPSL for benchmark testing before use.

Filter Integrity Testing

FIlter Testing Services

PPSL offers a full range of Filter testing services to support your needs. All filters are cleaned by us first and are then fully tested. The results are impeccable.

As standard, the following tests are undertaken for each project:

  • Bubble Point Testing
  • Flow Testing
  • Weight Check
  • Visual Inspection

Metallic Cleaning Services

Our vast range of cleaning services means we can support all types of industry.

From focussing on the cleaning and testing of filters and filtration equipment for the Polymer sector, we have expanded into the Oil and Gas, Chemical, Utility, and Food and Beverage sectors. With new sectors we welcome new challenges and this has required research and development into alternative cleaning processes. 

Throughout the sectors we support, we provide processing of a wide range of parts including:

  • Metal Filters
  • Disposable Filters
  • Die Blocks
  • Pipework
  • Lifting Chains
  • Static Mixers
  • Spinnerets
  • Gears & Bearings
