For both a flow through and a recirculation fish farm, it is important to have good water quality for optimum growth conditions and to maintain good healthy fish.
BIO-BLOK® provides a high active biological surface which breaks down suspended particles, organic compounds and reduces nitrogen.
A submerged aerated filter (SAF) is often used for reduction of organic compounds and ammonia.
It uses a media to provide surface area for microorganisms and oxygen diffusers to aerate the water.
The open tubes and shape of the block give a longer travel way for the water which makes a greater interaction between oxygen and water and gives you an energy efficient system.
A Moving Bed Biofilm Reactor (MBBR) provides a larger surface area per volume which enhances contaminate reduction, especially ammonia.
When choosing BIO-BLOK® Random you benefit from a strong carrier which does not break down and provides an active surface so that the given surface area is all active.
Contact filtration or tube settler is used to reduce suspended solids (SS). The particles will be pushed together to create flocs which will settle at low hydraulic load (approx. 0.5 m3/(m2 x h)).
BIO-BLOK® is based on a helical chord which gives ideal conditions for the particles to attach to each other and hereby create larger particles which have a higher settling velocity.
By using BIO-BLOK® you can reduce the tank size needed for removing suspended solids.
