Abstract:
1. A core column simulation device for assessing an efficacy of a wastewater biotreatment system, the device comprising: a. a column simulation subsystem for simulating an operation of the wastewater biotreatment system using a sample obtained from the wastewater biotreatment system; b. a sample extraction subsystem to transfer an amount of fluid comprising an aqueous suspension of biomass from the wastewater biotreatment system into a sample volume within the column simulation subsystem at a simulated extraction rate that is equivalent or representative of a full-scale volumetric rate of fluid transfer through a corresponding volume of a core of wastewater extending a total water depth within the wastewater biotreatment system, wherein the sample extraction subsystem is operatively connected to the column simulation subsystem and to the wastewater biotreatment system; c. a sample return subsystem to transfer an amount of mixed liquor from the column simulation subsystem to the wastewater biotreatment system at a return rate sufficient to maintain a constant amount of fluid within the sample volume, wherein the sample return subsystem is operatively connected to the column simulation subsystem and to the wastewater biotreatment system; d. an aeration subsystem to introduce an aeration gas into the sample volume at a simulated aeration rate that is representative of a volumetric aeration rate of the wastewater treatment system, wherein the aeration subsystem is operatively connected to the column simulation subsystem; e. a gas emission subsystem to release a gas mixture from the column simulation subsystem, wherein the gas emission subsystem is operatively connected to the column simulation subsystem; and, f. a measurement subsystem to monitor at least one property of at least one fluid associated with an assessment performed by the column simulation device, wherein the measurement subsystem is operatively connected to the column simulation subsystem.
