A liquid concentrator having an evaporator assembly and a cyclonic separator includes features designed to improve the performance of the liquid concentrator. A settling chamber is separated from a sump of the cyclonic separator. A liquid inlet opening into a mixing chamber of the evaporator injects wastewater at low pressures. Features to aid in the cleaning of the liquid concentrator include easy open doors and clean water injection ports for cleaning interior portions of the liquid concentrator. In one feature a settling tank is disposed below the cyclonic separator and has a width that is larger than the width of the cyclonic separator.

A reservoir evaporation system for evaporating fluid from an open reservoir of effluent containing a contaminant includes a fluid evaporator, an air pump, and an air supply conduit functionally connecting the fluid evaporator with the air pump. The fluid evaporator includes a vessel adapted to be positioned in an operative position partially submerged on the top surface of the effluent in the reservoir with a lower chamber submerged in the effluent and an upper chamber extending above the top surface of the effluent. In operation, air from the air pump mixes with the effluent inside the fluid evaporator and subsequently is discharged through exhaust openings. A fluid discharge pipe can also simultaneously discharge aerated effluent back down into the reservoir. Fluid is thereby separated from the effluent in the lower chamber by evaporation in a controlled manner that minimizes spread of contaminants to surrounding environments by wind.

A waste heat recovery system is coupled to a flare or exhaust stack of, for example, a landfill gas treatment system, to recover at least a portion of the energy within the exhaust produced by the gas treatment system and provides the recovered energy either indirectly or directly to a secondary process, such as a wastewater treatment process, to thereby reduce the amount of energy needed to be otherwise input into the secondary process. For indirect transfer of energy the waste heat recovery system includes a transfer pipe connected between the exhaust stack of a primary process and a heat exchange unit while an induction fan connected to the transfer pipe operates to create a draft within the transfer pipe to facilitate movement of some of the exhaust gas from the exhaust stack of the primary process to the heat exchange unit.
A bustle for use on a flare or an exhaust stack of, for example, a landfill gas treatment system, efficiently transfers gas from the stack to a waste heat recovery system associated with the landfill gas treatment system without substantially affecting the operation of the landfill gas treatment process. The bustle enables the heat recovery system to recover at least a portion of the energy within the exhaust produced by the gas treatment system and to provide the recovered energy either indirectly or directly to a secondary process, such as a wastewater treatment process, to thereby reduce the amount of energy needed to be otherwise input into the secondary process.
