MBBR biofilm carrier process excellences of large specific surface,being easy to multiply biofilm,unease to fall off,high denitrification, good hydrophile,high biological activity and so on.It widely used in the MBBR sewage treatment biofilter,aquaculture farms, Koi Filter Media,etc.

Product features

Self cleaning due to turbulence
Due to the turbulent movement of the bio filter 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 bio filtration 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 liters of media.
