Oase Biotec 12, 18 & 36 Pond Filter

With Biotec 12, 18 and 36 OASE have once again set new standards for filter implementation in garden ponds. Simple operation, fast, clean maintenance, and an outstanding filtration result are the unique features of the new Biotec filters. Mechanical cleaning - 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 mat where 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"). Biological Cleaning 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 poorer 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, so many coarse particles are removed from circulation that only lightly polluted water actually reaches the filter sponges. This makes a longer than average cleaning interval possible.
