About Triangle Environmental Health Initiative LLC
Triangle Environmental Health Initiative LLC, doing business as Tri-Ehi, is a Durham, North Carolina-based for-profit limited liability company registered in SAM.gov since 2017, with a current HUBZone small business certification. The company specializes in environmental technology research and development, with a primary focus on innovative water treatment, wastewater management, and resource recovery solutions. Tri-Ehi has established itself as a significant player in federal research and development, particularly within the Environmental Protection Agency's Small Business Innovation Research (SBIR) program, with a demonstrated track record of securing multiple Phase I and Phase II research contracts totaling over $4 million.
Through federal contract awards, Tri-Ehi has consistently delivered advanced research and development services to the U.S. Environmental Protection Agency's Office of Research and Development. The company's contract work primarily involves developing innovative wastewater treatment technologies, including a compact modular treatment system for non-potable reuse of residential and commercial greywater, a zero-waste water and energy recovery system, and an electrodialytic nutrient recovery system for onsite wastewater treatment effluent. All of these contract awards were total small business set-asides under the SBIR program, with contract values ranging from $100,000 to $500,000, and performance periods typically spanning one to three years. The contracts are focused on developing sustainable water management technologies that can potentially reduce energy consumption, enable resource recovery, and improve water reuse capabilities.
On the federal grant side, Tri-Ehi has secured a significant National Science Foundation (NSF) Technology, Innovation, and Partnerships (TIP) program grant focused on advancing wastewater treatment technology. The most recent NSF grant, valued at $275,000, supports the development of a selective ion separation and recovery technology for wastewater treatment. This innovative project aims to create a method for simultaneously removing contaminants, recovering valuable byproducts, and producing clean water for non-potable reuse. The grant specifically targets developing an energy-efficient electrochemical process that can generate four distinct, highly concentrated product streams differentiated by ion charge and valence, with the broader goal of lowering financial and infrastructural barriers to advanced water treatment, particularly for economically disadvantaged communities.
