Previous studies have proven the significance of backwashing
and QQ techniques for reducing biofouling separately.
Hydrodynamic detachment of deposited particles in fluidized bed filter backwashing
Accurately measuring the turbidity of the water coming out of the filter is the best way to determine when backwashing
should occur, optimising drinking water plant performance and minimising operating costs.
System: Traditionally, the filter medium is made from fine granulometries that allow for an effective filtration process, but this has the disadvantage of requiring frequent backwashing
operations (and consequent filtering interruptions).
During the backwash process, the media bed will become fluidized and if proper attention is not paid to the compatibility of the sand with the GAC, intermixing and ineffective backwashing
In addition to the minimum water saving measures, the Merredin District Olympic Pool conducted an irrigation distribution test to reduce the amount of water used in the landscaping, and optimised usage of their automatic vacuum cleaner to reduce backwashing

The range of Ronningen-Petter AFR Series automatic internal backwashing
filter systems has been extended with the introduction of 152mm diameter tubular filter bodies.
Instead of random or scheduled filter backwashing
operations now occur only when various parameters are reached.
