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.

Oase Rotary Drum Filters

There are now three models in the Oase range, the largest, the Profi Drum is designed as a pre-filter for larger ponds and will easily handle ponds of up to 12,000 gallons or more. The Biotec Premium is a self contained filter system featuring biological as well as mechanical filtration and is designed as a complete filter system for smaller ponds. The Proficlear Premium Compact Drum is the latest in the Oase range and is designed as a complete filter system for small to medium sized ponds and features the Helix biological moving bed media technology. With this model the volume of biological media can be increased to match the fish population. Both the smaller (Biotec Premium and compact) drum filters can still of course be used as Pre-filters only, and installed in this way they will manage larger ponds with ease.

 To keep the drum filter operating at its most efficient, clean the sieve elements once per year with Oase pump clean, which has been specially formulated to remove limescale and other contaminants from metal and plastic surfaces to keep them free of contamination caused by limescale build up. Also great for cleaning pump impellors.In very hard water areas it may be advisable to carry out this cleaning process more regularly. To clean any item, dilute the pumpclean in a suitable sized container as recommended and immerse the sieve/pump for 24 hours to remove all traces of contamination.

Cetus Pre-Filter sieve

The Cetus pond sieve is a very efficient mechanical filter which can be fitted directly to a bottom drain or to a skimmer. It can be pump or gravity fed and incorporates a patented floating weir system which regulates the water level in the unit, and ensures a constant and even curtain of water flow over the stainless steel filter screen regardless of pump size. Water is pumped from the base of the unit back to the pond (or to the next stage of your filter) and the unit features a drain valve to remove solids which collect in the debris trap.

Specification Price
Pumped £495.00
Gravity £495.00
Delivery costs from £25.00 depending on Postcode
Cetus Sieve

 

Cetus Sieve in Use
Cetus Cutaway drawing

The stainless steel screen is 300 micron to ensure very fine solids can be removed, and owing to the curved 'ski slope' design of the screen, it cannot block.

 

Cetus are built in the same way, and from the same materials as the Nexus filter range, so they are remarkably strong, simple and yet very light. Dimensions 95cm high, 85cm deep and 55cm wide Delivery Cost from £29.50 - please contact us for exact delivery quote.
