TMC Bio-Sand Filters
The TMC Bio-Sand Filter combines the features of a fluidised
sand bed filter and a trickle tower in one versatile filtration
system.Water enters the unit at the base and flows upwards
through the fluidised bed filter in the centre of the unit.The
water reaches the top and trickles down the outside section of
the filter through the plastic bio-media, where extra biological
filtration takes place in addition to gas exchange. Gas exchange
can be enhanced by blowing air up the tower through the
included air inlet at the base of the filter.
All units are complete with supply pipework including an anti-
siphon valve, graded oolitic sand and TMC Bio-Rings, and ABS
replaceable sand diffuser bowl. All TMC Bio-Sand Filters feature
our unique, flexible double o-ring inlet and outlet boss system
for easy service and the simple removal and replacement of
pipework and components.
