Described systems produce high-purity carbon dioxide from a CO2-rich gas, such as from CO2-rich tail gas produced as a waste stream during an upgrading or conditioning stage in a renewable natural gas (RNG) biorefinery. An example method comprises H2S filtration, compression, and cooling of the CO2-rich tail gas, subsequent filtration of oil, water, VOCs, and other sulfur-comprising compounds from the CO2-rich tail gas, and subsequent drying and compression of the CO2-rich tail gas. The CO2-rich tail gas is then condensed and a portion of CH4 is separated from the CO2-rich tail gas via flash separation and column distillation. The CO2-rich tail gas is then communicated into a reboiler to further separate CH4 from the CO2-rich tail gas. After subsequent further chilling / cooling, if the CO2-rich tail gas has a sufficiently high CO2 concentration, the CO2-rich tail gas is a finished CO2 product, such as food-grade CO2 or beverage-grade CO2.

A system and method for reclaiming and treating groundwater collected from an underground level of a structure or building site to supply non-potable water to an end use system, such as an irrigation system, a pond, an equipment washing system, a cooling system, or a heating system. Groundwater seeps into such underground levels and has to be pumped out to prevent flooding the structure. Normally, this groundwater is discharged as a waste stream but can be treated for non-potable use using an three-stage treatment system comprising an ultrafiltration system, a water softener system, and a reverse osmosis system. The water softener system may be used or bypassed depending on acceptable TDS levels in the end use system and the TDS level of the reclaimed groundwater. Use of the system and method can save millions of gallons of groundwater per year per building site from being wasted.
