The OASE BioTec ScreenMatic² 90000 is an innovative auto-cleaning filtration system for both ornamental ponds and fish ponds alike. The filtration system operates using a rotating screen belt which intercepts solid waste upon entry and transfers this to a collection tray when filled. Waste levels are measured by a sensor bar which engages a cleaning cycle when the sieve screen belt is sufficiently filled with waste, the sensor bar position can be adjusted to suit the flow rate from different pumps and regulate the amount of waste intercepted before self-cleaning. Beneath the screen mechanism are a series of 16 filter sponges in 3 different grades of coarseness, these provide excellent biological filtration after the mechanical extraction, removing harmful soluble waste product. Water is also passed through Zeolite media in the front chamber which collects waste and nutrient in solution before water is returned to the pond.

The OASE BioTec ScreenMatic² 90000 is an intelligent, flow-through pond filter that provides automated mechanical waste removal and biological filtration. The water enters the filter via a flow spreader onto a 300 micron fabric belt which strains out solid waste particles. When sufficiently soiled, a sensor engages the motor which performs a cleaning cycle, transferring the accumulated waste into a collection tray below the screen. The control display also allows instant cleaning cycles at the press of a button. The waste sensor can be adjusted backward and forward to alter cleaning regularity based on waste accumulation. A cleaning brush is supplied to keep the fabric screen free of entrapped dirt.

After mechanical straining, water enters the the biological media, a series of 16 large filter sponges differing in coarseness. The blue foams are rough, violet are medium fine and red are very fine grade. These sponges provide an abundance of surface housing for aerobic bacteria to populate and breakdown soluble waste pollutants. Cleaning the foams is made easy by the compression handle used to push down on the foams to release any build up of organic waste. Water is then directed through cartridges containing 5kg of granulate media (zeolite) which bind unwanted nutrients and trace ammonia before returning water to the pond.

These figures are specified based on a vertical lift to the filter of up to 1 metre from water surface level.

An allowance of up to 5 metres of flexible hose pipe in 1 1/2" or 2" internal diameter connecting the filter pump to the UV/filter box has also been factored into these calculations.

For requirements that incorporate extended lengths of flexible hose, multiple elbow bends or excess vertical lift into the filtration system, the pump component of these filtration systems may need revising to ensure the recommended flow-through turnover rates are achieved.

A minimum water depth of 0.5 metres is assumed on all ponds containing fish. If used on ponds with a depth shallower than 0.5 metres, the UV component of these systems may need to be upgraded to allow for a warmer water temperature in Summer months.

If specified and used in accordance with these guidelines, the BioTec ScreenMatic² filtration systems fall under the OASE Clear Water Guarantee.
