Percolator biofilter

Control of residual gaseous emissions (polluted air, combustion gases, biogas, etc.) contaminated with NH3, H2S, VOCs, siloxanes, NOx, SO2, particles using systems that consist of an inorganic filling where the pollutants are absorbed and are biologically degraded.

Gases with polluting compounds generated in processes of treatment/valuation of agro-industrial waste, droppings, etc. and in livestock activities (breeding sheds, storage of droppings, etc.)

NH3 and H2S removal efficiencies >95%. Lower efficiencies in the elimination of odors and VOCs.

The possible accumulation of NH3 in the system can inhibit nitrification;
It is important that there is an appropriate N/C balance, and nutrients in the biofilters to ensure the growth of microorganisms;
Spread of pathogenic bacteria such aslegionellabecause of poor filter maintenance;
Generation of a residual effluent to be treated or valued;
