Biogas from a wastewater treatment plant is corrosive, contaminated, and inconsistent. Making it pipeline-ready takes more than a filter.

Unison Solutions designed and delivered a complete biogas pretreatment and upgrading system for Capital Region Water in Harrisburg, Pennsylvania.

It processes biogas through a three-stage membrane system to produce pipeline-quality RNG. At capacity, 2,700 GGE/day can be injected into the local utility pipeline.

That's transforming a waste gas into a revenue stream.

Wastewater isn't just waste. It's a reliable source of energy waiting to be captured.

For the Pleasant Grove Wastewater Treatment Plant in the City of Roseville, California, our team engineered and delivered a complete biogas upgrading system that converts what was once a byproduct into pipeline-quality RNG for vehicle fuel and onsite energy use.

The system removes H₂S, siloxanes, VOCs, moisture, and CO₂. Tail gas recovery goes a step further, generating heat and electricity for plant operations.

The result is reliable, on-demand performance built around the specific needs of this facility.
