Most of the digester gas produced at wastewater treatment plants never gets used to its full potential. At Redlands Wastewater Treatment Plant, it does.

Unison designed and delivered a complete biogas conditioning system for the site, removing Hâ‚‚S, moisture, particulates, and siloxanes so the gas burns clean in the plant's onsite boilers. That eliminates fouling and corrosion from contaminants that should've been stripped out upstream.

The system includes a custom access platform and flexible flow control, both engineered around Redlands's specific site constraints rather than adapted from a standard package.

A custom-designed system from Unison gives Capital Region Water multiple options for its biogas.

The pretreatment and upgrading system allows CRW to inject pipeline-quality RNG directly into the local utility grid, or divert biogas to on-site heating via the plant's existing hot water boiler.

That flexibility runs through the whole design. It includes purpose-built equipment enclosures, an integrated electrical room, and a three-stage membrane separation process, all engineered and factory-tested at our Dubuque, Iowa facility before shipment.
