Rotary Drum Filters
Rotary Drum Filters
Drum filtration has been in use for many years, both by the municipal water industry and the commercial fish farming industry as well as for
other industrial applications.
Only in the last four or five years however have units begun to be designed and marketed specifically for the Koi market.
Drum filters represent the most amazing , truly efficient and effective maintenance free mechanical filters ever conceived.
Essentially they trap solids down to micron size, as low as 60 microns, preventing dirt and detritus from entering the biological filter and
help to produce amazingly clear water. As the filter screens inside the drum get dirty the electronics inside recognise this and start an
automatic wash cycle without any intervention whatsoever.
Incoming pond water passes through to the inside of the large drum which has stainless steel screens enclosing the drum - so the incoming
water must pass through the screens on its way to the next stage of the filter. As it does so, all the dirt is left on the screen. As and when
the screens starts to get blocked, a wash cycle is started and high pressure water jets wash off the screen from the outside, washing all the
accumulated dirt into a special trap inside the drum, where it is led to waste. The drum and screens also rotate to ensure complete and
precise washing of the screen at each cleaning cycle. The wash process is completely automatic, but can also be manually controlled, and
with some models set to wash at specific time intervals as well.
