Biofilm carrier MBBR is a new carrier of biological suspension, which modified polymetric material with the addition of a bio-enzyme, adapted for all types of microganism, for rapid growth and reproduction, in order to dissolve organic matter in water.
MBBR biofilm transfer process features high specific surface area, easy biofilm propagation, high denitrification, good hydrophilicity, high biological activity, and so on, It is widely used in MBBR biofilter for wastewater treatment, aquaculture farms, Koi filter media, etc.
Peculiarities of the product:
1. Self-cleaning through turbulence
2. Due to the turbulent motion of the biofilter in suspension, the filter material is self-cleaning and does not require maintenance. This allows the filter to achieve optimum efficiency without disrupting periodic maintenance, avoiding unnecessary loss of bacteria inside the filter. This ensures a stable low ammonia and nitrite content in the water.
3. The high surface area of these products results in a small physical area required for the biofiltration plant.
Thanks to the intensive mixing of a medium like Kaldnes, aerated medium is self-cleaning and maintenance-free. This allows the filter to achieve optimum efficiency. Periodic maintenance is not required, which prevents unnecessary loss of bacteria and subsequent surges of ammonia and nitrite in the system.
Required Carrier Volume - With good turbulence and aeration, a 50 liter filter is needed to deliver from 0.25 kg to 0.75 kg 40% protein per day.
