What is the purpose of a biofilter?

Biofiltration is a pollution control technique using a bioreactor containing living material to capture and biologically degrade pollutants. Common uses include processing waste water, capturing harmful chemicals or silt from surface runoff, and microbiotic oxidation of contaminants in air.

Oysters are filter feeders that feed upon suspended particles in the water column, pumping such a high rate of water flow that they are considered an important biofilter that helps maintain system functioning (Baird and Ulanowicz 1989, Grizzle et al.

Also Know, what is a biofilter for aquariums? The biological filter, or biofilter, is a key component in the filtration portion of a recirculating aquaculture system (RAS). The biofilter houses the nitrifying bacteria and is the primary site where biological nitrification occurs.

Subsequently, question is, how long does it take for a biological filter to work?

While it may take a week or less for the population of ammonia-consuming Nitrosomonas to grow to sufficient numbers, the delay in Nitrobacter growth means it can be six weeks or more before nitrite is under control.

How do you grow nitrifying bacteria?

Below we will touch briefly on each of these.

  1. Water Temperature. The water temperature for optimum growth of Nitrifying bacteria is approximately 75 – 85°F.
  2. pH. The pH for optimum growth of Nitrosomonas is approximately 7.8 – 8.0.
  3. Dissolved Oxygen.
  4. Salinity.
  5. Micronutrients.
  6. Light.
