Abstract: The process described herein calls for reaction of the effluent as it flows through the plant. The use of high and low pressure venturies (Barnoulli's equation) are included in this design.The purpose of this high pressure venturi (wider reaction pipe) is to create a high pressure and temperature for the bacteria to live in. It also serves to slow the effluent down for a longer detention time and longer period of organic or inorganic reaction. This results, in the case of the sludge, that the flow speed is equal to the rate at which the bacteria consume their way toward the incoming sludge flow. This above mentioned flow produces points of maximum organic or inorganic reaction: (i.e. bacterial or combustions of various natures) at constant designated points in the venturi. This design has the capacity to produce a high quality natural gas.
