With the new Biotec 36 Screenmatic, OASE have once again set new standards for filter implementation in garden ponds. Simple operation, fast and clean maintenance with an outstanding filtration result are unique features of the new Biotec filters.
A specially designed sieve, the “Screenex”, retains all debris particles up to a size of 500 micron, which are pumped into the filter. After the water flows back through a special matt it is enriched with oxygen, it falls into the chamber below, flows through the filter zones, and then reaches the next filter chamber (“Individual chamber”).
The nitrosomonas and nitrobacter bacteria present in the pond water settle and multiply in the oxygen rich filter zones (blue sponges) and in the oxygen poor zones (red sponges and individual chamber). In various biological processes they convert toxic ammonium/ammonia via nitrite to nitrate and finally to gaseous nitrogen. The individual chamber situated just in front of the outlet, is called “individual” because every consumer has the choice of which filter material to insert (i.e. OASE Phosless). The chamber is equipped as standard with Zeolite.
Long service life
With the Screenex filter process happening prior to the actual filtration, many coarse particles are removed from circulation and only lightly polluted water actually reaches the filter sponges. This makes a longer than average cleaning interval possible.
With the new Biotec 36 flow-through filters SCREENMATIC enables the Biotec 36 to remove coarse debris from the pond in a manner that is even easier and safer.
Water intake, and thus flow speed as well can be adjusted individually via a function controller attached to the water distributor on the SCREENEX.
The SCREENMATIC system can be folded up and out of the way at a 90 degree angle to provide free access to the filter sponges, it is no longer necessary to take the sponges out of the filter for cleaning. The special tool provided makes it possible to clean the sponges where they are situated in the filter.
The Oase Biotec 36 has an appropriately dimensioned SCREENMATIC and a 70mm sludge drain outlet, operated by an internal slide valve making it easy to drain the filter.
