Indian River Commercial Proposal for <br />Installation and Operation of HEARTLAND <br />0 Eco -District <br />Pilot Leachate Treatment System ViAT`` '^`''""--� <br />A Frankens Energy Initiative <br />Annex B: HEARTLAND TECHNOLOGY PROCESS DESCRIPTION for PILOT SYSTEM <br />Heartland's 1,000 Gallon per Day PILOT Concentrator operates via a direct -contact thermal evaporative process to treat <br />and concentrate landfill leachate and other potential landfill fluids. In the case whereby Indian River County elects to <br />proceed with the deployment of a full-scale system after this pilot, the full-size system would likely derive its energy from <br />either the residual heat emitted from other power generators, or through the combustion of natural gas or landfill gas. <br />For the purposes of this pilot system, the process will utilize an electric heater as the thermal energy source. The <br />process flow is intended to mimic to the extent possible a commercial system. <br />1. Landfill leachate is fed to the Concentrator from a dedicated leachate collection point (e.g. sump, tank or equivalent, customer <br />provided) via a submersible transfer pump. <br />2. A fully integrated electric heater provides necessary thermal energy for landfill leachate processing and evaporation. <br />3. The hot gas transfer system collects, tempers, and routs thermal energy to the Concentrator at temperatures between 800°F and <br />1,000°F. <br />4. The Concentrator mixes the hot gas with Landfill leachate in the evaporation zone in an adiabatic process; the resultant vapor <br />stream is nearly saturated with water vapor at —150°F. <br />5. The nearly saturated vapor stream passes through a high -efficiency, multi -stage entrainment separator where residual water <br />droplets are collected and removed. <br />6. An induced draft fan draws the demisted vapor through the system and directs it through the process exhaust stack. <br />7. The residual concentrated Landfill leachate is continuously circulated through the system via the system recycle pump. <br />8. Advanced density controls maintain a desired level of Concentration in the residual brine. <br />Copyright 2019.
