It is important for the quality of the surface finish that the plating solutions are kept free from particulate and build-up of organics does not occur.
Most finishers will have a recirculating loop on the plating bath that includes a particle removal filter such as a bag, depth or surface (pleated) cartridge. Intermittently, a carbon cartridge is used to clear up the organics that build up from environmental conditions and elements directly introduced, such as the components and racks.
Stages of Filtration & Water Treatment
Bulk Solids Removal
To remove a high quantity of solids, gels and other irregular shaped particles, a filtration solution with high surface area and flow properties is required.
Prevents debris, scale flakes, dirt and particle build up in pipework, tanks, equipment and where present, premature blinding of filtration stages further along the cascade.
Efficient Particle Removal
Controlling quality levels by removing the majority of contaminants at a specified micron size.
SPECTRUM Economic Bag
Traditional single skin with handle. Used to remove sediment from high flow or viscous applications. WRAS approved and FDA compliant.
SPECTRUM TruDepth Standard Spun-Bonded Cartridge
Boasting WRAS approval over the ESP, the TruDepth Standard is the best value option for general particulate reduction. With a recognisable mini-grooved construction, the SSP has a higher surface area and enhanced dirt holding capacity over the TruDepth Economic cartridge (ESP).
Low levels of energy are required to flow liquids through these very efficient filters due to their exceptionally large surface area.
