• BioTec ScreenMatic Filter Set 40000

  • The OASE BioTec ScreenMatic² Set 40000 consists of the BioTec ScreenMatic 40000² pond filter, the AquaMax Eco Premium 12000 pump and the Bitron 36C ultraviolet clarifier.

    The BioTec ScreenMatic 40000² is a pond filtration system incorporating an automatic waste screen, foam banks and zeolite binding media. Incoming water is discharged onto the screening belt which intercepts organic waste down to 300 microns. A waste build-up sensor on the screen mechanism detects when sufficient waste has accumulated and automatically activates a cleaning cycle, offloading the collected solid waste into a large collection tray.

    Beneath the screen mechanism are banks of OASE filter foams in different grades of coarseness. These filter sponges provide surface area for biological filtration of the mechanically screened water. Water passing through the system is also circulated through zeolite media which absorbs unwanted nutrients and gasses in solution. Supplied 100ml BioKick will immediately start the biological process. The AquaMax Eco Premium pump delivers an optimum rate of turnover through the filter, passing organic solids up to 11mm in size whilst consuming minimal energy. The Bitron 36C ultraviolet clarifier fixed to the filter box inlet will process algae/green water entering the system.

OASE BioTec ScreenMatic² Filter Sets

The OASE BioTec ScreenMatic² Sets are complete pond filtration systems consisting of a BioTec ScreenMatic² pond filter, an AquaMax Eco Premium Pump and a Bitron C ultraviolet clarifier. Each set has been comprised specifically to suit ponds of different water volumes and fish stock (species and stocking density). Based on this information, these automated-clean, energy efficient filtration systems will achieve an optimum rate of water turnover through the filter, tacking algae, solid and soluble waste, resulting in clean, clear and healthy pond water.  

BioTec ScreenMatic² Pond Filter

The OASE BioTec ScreenMatic² 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 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 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 of granulate media (zeolite) which bind unwanted nutrients and trace ammonia before returning to the pond.

The large collection tray stores solid waste products intercepted by the screen and is easily removed for emptying.

The fabric screen belt will intercept particles as small as 300 micron which allows the foam media to perform primarily as biomedia.

The supplied cleaning brush enables the screen to be gently cleared of debris without the risk of tear or abrasion.

The simple addition of robust locking clips on the lid prevents the lid being unintentionally dislodged or blown off in strong winds.

AquaMax Eco Premium Filter Pump

The AquaMax Eco Premium filter pumps are high performance filtration pumps with Eco Plus motors for excellent output and very low running costs. These advanced filtration pumps are built with technical features and unique functions. With double layered outer strainer for continuous pumping when masked, solids-handling up to 11mm particle size and secondary inlet feature for connecting a strainer or surface skimmer, these pumps are perfect for supplying to flow through filters such as the BioTec ScreenMatic.

Technical features include dry run protection via unique Environmental Function Control, this shuts the pump down if it begins to run dry to prevent overheating. The AquaMax Eco Premium pump will then restart in 'test mode' to ensure it is fully flooded before reverting to full output. The pump can be installed in dry scenarios by principle of flooded suction, connecting a pipe to the inlet below water level to provide a continuous flood of water into the pump. Models 12000, 16000 and 20000 also feature a Seasonal Flow Control function which if switched on will automatically reduce the flow of the pump if the water temperature drops very low, ideal for saving energy in Winter.

These pumps are guaranteed as standard for 3 years. Upon registering your purchase with OASE, an additional 2 years are guaranteed!

Eco Plus is OASE’s most energy efficient rating, meaning the AquaMax Eco Premium delivers superb performance using minimal power.

Bitron C Ultraviolet Clarifier

The OASE Bitron C are excellent ultraviolet clarifiers for fish ponds. These UV units feature twin outlets for direct connection to OASE filters, flow bypass fuctions to optimise flow over the UV light and spinning cleaning mechanisms that perform continuous rotation generated by the flow from the pump, keep the quartz glass sleeve free of debris and maintaining excellent efficiency from the UV light and clear water in the pond.

These UVC units are also built with safety in mind, with a safe viewing window that indicates lamp activeness without direct exposure. There is also a cut out switch built into all Bitron C units that will prevent the lamp from lighting up if the housing and ballast unit are separated.

Pond Turnover Rates: The pond stocking levels will determine the required turnover rate which in turn determines the required pump flow rate. Typically, an ornamental pond without any fish will require the pond volume to be circulated at least once every 6-8 hours; an average stocked pond (with up to 1 kg of fish for every 1000 litres) will require circulating once every 4 hours; a heavily stocked pond including Koi (with up to 2 kg of fish for every 1000 litres) will require circulating once every 2 hours. BioTec ScreenMatic Set pump selections allow for increased flow lost through the filter foams as they become polluted with pond waste (see the importance of regular maintenance, below).

Pump Flow Rate: The pump flow rate, typically in litres per hour (lph) or litres per minute (lpm) is determined by the vertical lift, in metres, from the surface of the pond to the outlet pipe AND by the friction losses through the system. The narrower the pipe bore the higher the friction losses, so always use the maximum hose diameter. There will also be a friction loss caused across the filter media (foams etc), which will increase as they become polluted with pond waste.

Effect of raising the filter: Raising the filter height, typically for a watercourse or waterfall, will reduce the flow rate from the pump thereby increasing the amount of time it takes to circulate the dirty pond water through the filter. This effectively reduces the maximum pond volume that the filter system can cope with and may mean you will require a larger pump. Please contact us and we would be happy to advise you.

The importance of regular maintenance (cleaning): High flow rate = effective filtering. As the filter media (e.g. screen and foams) remove dirt and waste from the pond, so the friction loss across the foams will increase, thereby reducing the flow rate and the effective performance of the filter. It is therefore essential, especially for those systems with a raised outlet, to keep the filter foams clean. Fortunately, this is extremely easy with OASE BioTec ScreenMatic pond filters.
