Manure compost biofilters

Manure compost biofilters play a major role in treating organic and inorganic emissions from a variety of industrial and wastewater treatment processes.Biofiltration can reduce ammonia emissions from the composting process.The odor removal efficiency of manure compost biofilters varies with the air flow rate and surface loading rate. During biofiltration, odorous air passes through a layer of manure compost biofilters, The odor components are transferred from the gas to the liquid and solid phaseon the biofilter media particles.Manure compost biofiltration involves two principal actions: 1) physical adsorption on compost particles and 2) microbial degradation of the compound.Microbial action can involve metabolisms, utilization or oxidation of organic compounds. Manure compost biofilter media had considerable influence on ammonia emission and ahigher reduction of ammonia emissions occurred in biofilters containing manure compost.l
