Process sequencing and timing have been optimised during months of field studies at the Spence project in Chile. Efforts have also been focused on removing the dirty backwash water from the vessels after the typical cleaning cycle has completed.
These improved draining techniques are due to a radical new design of the filter's internal backwash outlet header.
The standard backwashing step in Dual Media and CoMatrix filters only releases organics from the saturated anthracite layer.
Typical plant operations do not allow for a volume large enough to efficiently flush all released organics, and may never be able to purge the floating organic volume regardless of the backwash duration.
The new design allows floating organic to be skimmed from the surface rather than drained from the bottom. This prevents organics from returning to the media bed which slowly decreases service performance over time. This improved recovery technique allows fewer media changes. All recent optimisations can be implemented into existing Dual Media and CoMatrix filters currently in operation.
