The product description

 FBB series of floating bed biological filter is our latest product, which uses solid fluidization technology and tiny particles with a huge surface area of the principles and characteristics of the concentration of the filter and activated sludge method of the advantages of biofilm highly concentrated, the concentration High, high efficiency of purification, ammonia nitrogen conversion rate can be increased 2 to 4 times. It has the advantages of small footprint, non-blocking or good biofilm activity compared with the conventional biofilter, biological drum, biological turntable and activated sludge. Due to improve the efficiency of water purification, and thus can reduce the construction costs and covers an area, and easy to manage.

Our floating bed biological filter with biological filtration, mechanical filtration of two functions, but also has anti-cleaning function, the product running low energy consumption, installation and operation of a single, and can easily be added to a complete circulating water treatment system among.

The product features

 Floating bed biological filter is composed of the main reaction room, water device, multi-layer biological filter, anti-washing device, sewage, bottom emptying, water and other components. The normal working flow is: the aquaculture water to be treated is poured into the water inlet device inside the floating bed biological filter by the upper processing equipment. The large particles (larger than 1) in the water will have the effect of centrifugal force Large particles of sewage outfall, and the rest of the small particles containing suspended solids in most of the culture of sewage from the bottom up through the multi-layer biological filter, this time multi-layer biological filter was suspended in the main reaction room, in the solid fluidization Under the action of the technology to form a mobile multi-level filter bed, the small particles of water suspended by the flow of multi-layer filter bed filter (mechanical filter function), multi-layer biological filter (specific surface area) while training biofilm Nitrifying bacteria and nitrifying bacteria), so that the water ammonia and other harmful substances by the biological filter surface biofilm nitrifying bacteria conversion, to remove water containing nitrogen harmful substances. The water treated by the multi-layer biological filter is discharged from the outlet to the next level. Anti-Cleaning Workflow: When the gap between the layers of biological filter is filled, the floating bed biofilter requires recoil to remove the suspended matter. At this time, floating bed biological filter to stop the water, multi-layer biological filter with mechanical way to break up, suspended solids and multi-layer biological filter from the bottom of the filter, the multi-layer biofilter flow to the upper part of the filter The flow of the multi-layered filter bed, the precipitated sludge is discharged after a new filter cycle begins.
