High capacity mechanical / biological flow through with multi chamber filters for clear ponds. For ponds up to 140,000 litres with maximum flow rate of 23,000 LPH.
The patented silt disposal system allows quick and easy cleaning of the filter and ensures if used correctly the continued development of micro-organisms.
These filters are generally pump fed filters and multi chamber filters, which do not only mechanically filter out dirt from the pond water but also encourage the colonisation of special micro-organisms for the biological filtration process.
Biotec was scientifically developed and tested, and guarantees that if used according to the instructions and in round the clock operation, crystal clear and biologically sound pond water.
With the Biotec 12, 18 and 36 Screenmatic's 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 100 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 nitro bacter 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, 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.
