PEPLYN HA Liquid Filters

Dominick Hunter

One measure of a filter's performance is the amount of contamination that it can handle before the flow of liquid reduces, or the pressure drop increases, to unacceptable levels.

It is possible to adjust a filter's capacity to handle contamination by enhancing the depth and porosity of the media. This approach traps the contamination throughout the depth of the media, leading to increased life to blockage, but makes it difficult to further extend filter life by cleaning.

PEPLYN® HA has been specifically developed to provide substantially extended life through repeated backwash regeneration.

PEPLYN® HA utilises polypropylene filter media and support materials, which balance a high surface area and closely controlled porosity, in a configuration that maximises the cleaning efficiency of backwashing.

Capture of larger particles is predominantly on the surface of the media and by utilising a robust and rigid construction surface blinding can be significantly reduced by backwashing. By using a graded fibre size and density throughout the media depth, coupled with closely controlled porosity, the loading capacity is maximised and retention of smaller particles is accurately defined and maintained under wide extremes of operating conditions.

PEPLYN® HA filter cartridges are ideally suited to applications with high natural dirt loading or where artificial filter aids (eg. kieselguhr) have been used to provide bright products.


• Raw water filtration where the longevity of the filter can be enhanced by repetitive backwashing
• Trap applications, removing pre-coat and body feed particles that have been released from powder filters, for example, in the brewing process
• Removal of carbon and resin 'fines' downstream from treatment processes
• Clarification of CIP solutions prior to their use with fine pre-filter cartridges and microporous membranes
