The treatment of animal residues is very wide. Residues from mammals and birds have to go through a biological system at some stage; the trickling filter or a mobile bed are some of a range of very efficient systems. For trickling filters we propose plastic filling BIOFILL® type A or BIOFILL® type B. Biología y Filtración, S.L. can do for you the calculations of the facilities. This treatment can go along with the addition of BACTERIA® products.


In the case of fish farming wastewater, the recommended treatment is a mobile bed. This system is performed by adding the high efficiency plastic filling BIOFILL® type C in a system of activated slugdes. The process is completed by adding BACTERIA® biological products.
