Abstract: A method for improving the efficient use of fluid and for improving the odor control in in-vessel composting. The method includes the re-use of exhaust fluid from a first composting reactor in a second composting reactor in a single multiple chain system. Improved odor control is achieved by the provision of an odor control device interposed in the fluid stream from the first composting reactor to the second composting reactor and passing exhaust fluid from the first reactor through the odor control device to remove pollutants therefrom before re-use in the second composting reactor. The exhaust fluid from the second composting reactor may also be passed through the odor control device before it is exhausted to the atmosphere.

Abstract: The present invention provides an apparatus with improved fluid flow control for economical and efficient composting. The improved fluid flow control is provided by a lance having at least two separate fluid flow zones to provide a fluid flow profile in the compost. The flow zones are provided by an outer porous wall tube with a control insert tube therein having a plurality of openings along the length thereof and spaced from the wall by gaskets to form the flow zones. The lances can be coupled to a manifold for even fluid distribution throughout the compost. The manifold is designed to direct fluid flow to a portion of the lance while simultaneously removing fluid flow from the other portion of lances. This creates substantially uniform patterns of fluid injection and evacuation for uniform composting, reduced energy requirements and greater control of process conditions. Further, reversal of the fluid flow enhances control of process conditions and adds an automatic self cleaning aspect to the apparatus.

Abstract: The present invention provides a method and apparatus for controlling combustion in a compost or amendment mass. The fire control fluid flow control is provided by a lance having at least two separate fluid flow zones to provide a fluid flow profile in the compost or amendment mass. The flow zones are provided by an outer porous wall tube with a control insert tube therein having a plurality of openings along the length thereof and spaced from the wall by gaskets to form the flow zones. The lances can be coupled to a manifold for even fire control fluid distribution throughout the compost or amendment mass. The manifold is designed to direct the first control fluid flow to a portion of the lances.
