These products are suited to fluidized or moving bed tank systems. These are also called “Biofilm Reactor”, “moving bed reactors (MBBR or MBR)” systems, polyethylene media and are used for the treatment of water and wastewater. Similare media are MB3 media, Kaldnes and EEC media. BFCL03 can support about 16 kilograms of fish per 50 liters of media, where fish are fed 1.5% of their body weight per day. Alternatively, a maximum of 0.75 kilogram of 40% protein food per 50 litres of media per day. A safer measure is a maximum of 0.25 kilograms of food per 50 litres used, in order to ensure the best possible water parameters are achieved.

The moving bed process is ideal for COD and BOD reduction as well as nitrification and denitrification. In nitrifying applications, use a blower to continuously circulate the  elements, while simultaneously oxygenating the water and stripping the  CO2. The self-cleaning action allows for the exfoliation of the older,  less active bacterial layer and eliminates the need for backwashing.

Self cleaning due to turbulence

Due to the turbulent movement of the biofilter media in suspension, the filter medium is self-cleaning, requiring no maintenance. This allows the filter to reach optimum effectiveness without the disturbance of periodic maintenance, avoiding unnecessary loss of bacteria within the filter. This allows stable, low levels of ammonia and nitrite within the water.

The first few of these products are similar to the patented Kaldnes media used in fish farming and waste water treatment. The design creates an environment for effective nitrification to take place. Water flow is created by aeration that circulates the media throughout the vessel. This high surface area of these products translates into a small physical area needed for the biofiltration unit.

Due to vigorous mixing of the Kaldnes-like media through aeration, the media is self-cleaning, requiring no maintenance. This allows the filter to reach optimum effectiveness. Periodic maintenance is not necessary, preventing the unnecessary loss of bacteria and subsequent ammonia and nitrite spikes in the system.

Media volume needed

With good turbulence and aeration, a feed rate of between 0.25kgs  and 0.75kgs of 40% protein food per day requires 50 litres of media.
