  • Filtration Processes IWA Publishing

    Filtration is a process that removes particles from suspension in water. Removal takes place by a number of mechanisms that include straining, flocculation, sedimentation and surface capture. Filters can be categorised by the main method of capture, i.e. exclusion of particles at the surface of the filter media i.e. straining, or deposition within the media i.e. in depth

  • Agitation air sizing and calculations for plating amp; anodizing

    You could use a simple mechanical agitation system instead of air agitation. You could (perhaps, depending on the type of pump) use a valve or smaller diameter tubing to lessen the air volume or at least try drilling larger holes in the hose so gravity propels the bubbles rather than pump pressure spraying it. Good luck. Regards,
