The biological purifier with plastic filling percolator bed is a technique that has been known for many years and which is meeting a renewed interest today due to the success of modern filling bodies, which allow high performance to be obtained in the absence of clogging.
In the tank section where the biological-oxidative process takes place, microorganisms develop
spontaneously and are able to live, grow and reproduce.
In the bacterial bed the conditions are artificially created that regulate the natural phenomenon of the self-purification of a watercourse, determined by the presence of aerobic microorganisms that use the organic matter present in the water and transform it progressively into stable end products.
Through the filling bodies the water passes and the organic substance, fixing itself on the inert support, is attacked by the microorganisms that start the biological degradation process.
Diffusers and micro-bubbles placed on the bottom help to ensure the necessary supply of oxygen to the water.
Biological purifiers have a simple and completely automatic functioning and do not require the use of chemical products; their management costs are very low, the water they treat is free of unpleasant odours
and has effective recycling possibilities.
