Abstract: Liquid water removal apparatus that removes residual liquid water in a fluid conducting system by vaporizing the residual liquid water and drawing the vaporized water from the fluid conducting system. A vacuum pump (a) reduces the atmospheric pressure in the fluid conducting system to vaporize residual liquid water in the fluid conducting system, (b) draws from the fluid conducting system vaporized water, and (c) partially condenses the vaporized water drawn from the fluid conducting system. Vaporized water is conducted from the vacuum pump to a first water vapor condenser where vaporized water is condensed and residual vaporized water is conducted from the first water vapor condenser to a second water vapor condenser where the residual vaporized water received from the first water vapor condenser is condensed.

Abstract: Methods and systems for processing animal waste are disclosed. Effluent, including waste solids and water, is received. The effluent is at least partly separated into solids and water. The separated water is processed using a dissolved air flotation device and/or a reverse osmosis system to clarify the separated water. The separated solids are transferred to a gasifier, which processed the separated solids to form a least a first gas.
