Biofiltration of gasoline vapor by compost media.
Gasoline vapor was treated using a compost biofilter operated in upflow mode over 4 months. The gas velocity was 6 m/h, yielding an empty bed retention time (EBRT) of 10 min. Benzene, toluene, ethylbenzene and xylene (BTEX) and total petroleum hydrocarbon (TPH) removal efficiencies remained fairly stable approximately 15 days after biofilter start-up. The average removal efficiencies of TPH and...
متن کاملCompost liquor bioremediation using waste materials as biofiltration media.
Compost liquor results from the percolation of precipitation through composting waste; the release of liquids from high moisture content feedstocks; and as a result of runoff from hard surfaces and machinery. This research aimed to establish the potential for waste materials to act as media for low-cost compost liquor biofilters. Six types of potential biofilter media were packed into experimen...

متن کاملVermicompost as Biofiltration Media to Control Odor from Human Feces
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...
متن کاملCharacterization of artificially dried biofilms for air biofiltration studies.
One of the main problems associated with the operation of air biofilters is the loss of performance caused by drying of the bioactive support, as the removal capacity of contaminants by the microorganisms is dependent on their water content. In this work, biofilms from a microbial consortium adapted to toluene were grown on stainless steel slides. The biofilms were dried in stoppered flasks wit...
