Why does Deltec Fluidize the Media?
With the Mk 5 Deltec Fluidised Calcium Reactors, fluidising the smaller grains of Rowalith C+ ensures that the whole of the surface of the media is always available for reaction with the low pH water within the chamber. On a standard non fluidising reactor the water always finds the easiest route through the media and forms channels or tracks which can result in only a small area of the media being utilised.
Deposits of fine media build up within a standard reactor which choke up the pathways further and require regular maintenance and cleaning out to maintain a reasonable level of efficiency. With the Deltec reactors the fines are kept in suspension and pushed out of the reactor with the water which means that the media never needs to be emptied out and cleaned but simply topped up.
The NEW Mk5 reactors are now fitted with a new design of Aquabee pump which have overcome issues that were present on a small number of Mk4 models.
