CREW Carbon Advances HRSD Partnership to Demonstrate Multi-Benefit Wastewater Technology

CREW Carbon is the focus of this weekly summary of notable developments, as the company advanced deployment of its process intensification technology with leading Virginia wastewater utility Hampton Roads Sanitation District (HRSD). During the week, CREW Carbon highlighted that its solution is being installed at two HRSD wastewater treatment facilities, targeting enhanced biological treatment performance, lower operating costs, and improved sludge settleability.

The company emphasized that its technology is designed to support biological nitrogen and phosphorus removal, particularly under alkalinity-limited conditions that challenge many utilities. HRSD Chief Technology Officer Dr. Charles Bott described the approach as “transformational” for facilities pursuing advanced nutrient removal, underscoring the potential significance of CREW Carbon’s offering in demanding municipal applications.

Beyond process performance, CREW Carbon positioned its solution as a multi-benefit platform for utilities by combining operational, financial, and environmental advantages. The company noted potential operating expense reductions through substituting conventional chemicals, enhancing nitrification, decreasing metal salt use for phosphorus removal, and potentially improving sludge thickening and dewatering outcomes.

CREW Carbon also pointed to prospective capital expenditure savings enabled by process intensification and lower-turbidity effluent, which may allow utilities to defer or downsize certain infrastructure investments. Additional benefits cited include reduced operator exposure to hazardous chemicals such as sodium hydroxide, along with more stable biological performance that could help utilities maintain permit compliance through better and more consistent effluent quality.

From an environmental standpoint, the company highlighted that its process aims to enable permanent removal of greenhouse gases while lowering overall carbon footprints. This is achieved in part by replacing carbon-intensive chemicals with locally sourced minerals and reducing process emissions, a combination that aligns its value proposition with growing decarbonization and regulatory priorities in the water sector.

For CREW Carbon, the HRSD collaboration serves as an important reference deployment that may validate its technology at utility scale and in technically rigorous conditions. If successful, the project could strengthen the company’s positioning in water technology and climate-focused markets, support future customer adoption, and lay the groundwork for recurring revenue opportunities with municipal and regional wastewater utilities. Overall, the week marked a strategically important step in demonstrating CREW Carbon’s multi-benefit wastewater platform and its potential role in next-generation treatment and emissions mitigation.
