SHARC Energy has secured a purchase order for its newly introduced Back-Flush Only (BFO) system for deployment at a wastewater treatment plant in Calgary, Alberta. SHARC Energy says the order marks the commercial launch of the BFO product line and expands its portfolio for applications where source effluent contains no or minimal solids and where high- to medium-temperature effluent is available.

According to SHARC Energy, the BFO system is a passive thermal energy transfer solution optimized for cleaner effluent streams and does not require solids separation or maceration. The company says it is designed to harvest and move thermal energy from suitable hydronic sources to where that thermal energy is needed.

SHARC Energy lists BFO target applications as non-solids effluent streams, grey water, wastewater treatment plant discharge, data centers, hydronic heating, ventilation, and air conditioning (HVAC) systems, district heating and cooling, and Ambient Temperature Loops (ATL’s). By focusing on cleaner source streams, SHARC Energy says BFO addresses facilities and infrastructure environments where traditional wastewater energy recovery systems may not be required.

“This purchase order represents more than a project win — it represents the successful launch of a new product category within our portfolio,” said Michael Albertson, CEO and President of SHARC Energy. “The BFO system allows us to address a broader range of applications, particularly wastewater treatment plant effluent, data centers and hydronic loop systems, where passive thermal transfer can unlock significant energy recovery without complex solids management.”

SHARC Energy positions BFO alongside its existing products: PIRANHA, which it describes as a wastewater-source heat pump using a “unique evaporator design” capable of delivering potable hot water up to 140°F (60°C) with a coefficient of performance range of 3.0–6.0, and SHARC, which it describes as scalable passive thermal energy transfer systems for higher-solids wastewater applications and large-capacity district and multi-building systems. The company also reports that since its February 4, 2026 disclosure and as of March 4, 2026, its Sales Order Backlog (a non-IFRS measure) has increased to $7.8 million, without consideration for any shipments or adjustments since the third quarter of 2025.
