Vermicompost as Biofiltration Media to Control Odor from Human Feces
نویسندگان
چکیده
There are a number of options to control the odor during the degradation of organic wastes and biofiltration is one of them. Fresh vermicompost has a high surface area, adequate absorption capacity and high diversity and population of micro-organisms. Vermicompost helps in degradation process as well as in suppressing the odor. Study was organized in order to use the vermicompost as a biofilter media to suppress odor and optimize the thickness of vermicompost to remove/degrade the volatile fatty acids (VFA) emission. The 2.5 cm thick vermicompost layer in bedding and covering was found to be sufficient enough to eliminate the odor of system and reduce the Volatile Fatty Acids level from 161.55 to 39.61 mg/g within a period of 21 days.

Measurement of biosolids compost odor emissions from a windrow, static pile, and biofilter.
A pilot study was conducted to compare odor emissions from a windrow process and an aerated static pile and to determine the odor reduction efficiency of a pilot two-phase biofilter for odor control of biosolids composting. Chemical compounds identified as responsible for odors from biosolids composting include ammonia, dimethyl disulfide, carbon disulfide, formic acid, acetic acid, and sulfur ...

Abstract. A mobile biofilter testing laboratory was developed where two types of wood chips (western cedar and hardwood) were examined to treat odor emissions from a deep-pit swine finishing facility in central Iowa. The biofilters were run continuously for 12 weeks at different air flow rates resulting in variable empty bed residence times. During this test period, a dynamic forced-choice olfa...

Vermicompost singly and in binary combination with different biopesticide were used in agricultural field to control the infestation of nematode (Meloidogyne incognita) and high yield of cauliflower (Brassica oleracea) crop. Mixing of binary combination of vermicompost with neem oil (94%) in the soil caused significant reduction in M. incognita. The combination of garlic extract with different ...
