Shockproof Floating Filter K1 Micro Filter Media White

How does MBBR work?

Bio Media Plus is designed to be slightly buoyant and move freely or remain static (still) in your filter. The bio-media provides the maximum surface area necessary to allow beneficial bacteria to colonize (grow) and remove ammonia and nitrites from your water. Removing ammonia and nitrites from your water is essential for healthy koi (fish). As the bio-media moves around in the filter chamber the bacteria go to work and start removing the ammonia and nitrites. When your bacteria mature Bio Media Plus is the perfect and most efficient way to remove ammonia and nitrites.

How is Bio Media Plus different and self cleaning?

Bio Media Plus is engineered and designed to provide a place for the bacteria to grow and still be protected while it is moving around in the filter chamber. While water and air in your filter chamber cause the bio-media to move around, the “old” or “dead” bacteria along with any solid waste to fall off. This chaotic movement makes the filter media self cleaning. This will also make room for new bacteria to colonize inside the protected wheel.

Discriminant index:

1. Adhesion of biofilm

Adhesion capacity of biofilm - the most important index to evaluate the quality of fillers: biological adhesion = protected surface area (connected with the design of fillers

running state

running state

Structure related) × bioadhesion per unit surface area (related to the performance of filler)

2. Filler performance

Performance of packing - the most important index to evaluate the biological adhesion of packing

(1) Surface properties of fillers

1. Surface structure: it is generally considered that the surface roughness is large and the film hanging speed is fast.

2. Surface potential: generally, microorganisms are negatively charged, and the surface of filler is positively charged, which is suitable for microbial growth. 3. Hydrophilicity: the microorganism is hydrophilic particle, and the filler has good hydrophilicity and is suitable for microorganism growth.

Film hanging state

(2) Hydraulic properties

1. Porosity: volume occupied by filler, high porosity.

2. Shape and size: affect the flow pattern of water and air flow.

(3) Fluidization performance: it is related to the density of filler. The density of the packing should be 0.97-1.03, and fluidization can be achieved with less aeration or agitation.
