Triangle Environmental proposes the Zero-Waste (ZeWa) water and energy recovery system; a netenergy positive onsite wastewater treatment system to eliminate brine and produce three output streams for reuse. Aging sewer infrastructure coupled with a growing population and sewer demand in the US have fostered a shift to higher usage of onsite wastewater treatment systems (OWTS). In the US, decentra ...

Membranes are the gold standard for water treatment and reuse. However, membrane fouling inhibits flux, wastes energy, requires cleaning and replacement, and disables concentrate recirculation. Pure Blue Tech proposes ultrasonic PVDF transducers be embedded within membrane systems to reduce fouling. This innovation has potential to transform the economics of membrane operations and water reuse. Pu ...

Fats, oils and greases (FOGs) cause 75% of sewer systems in the US to operate at 50% capacity, cost US cities over $20 billion in sewer maintenance, and cause over 40,000 sewer overflows annually. Most commercial kitchens are required by law to remove FOGs with a grease interceptor from wastewater before emitting into public sewers. In order to reduce sewer maintenance costs and overflows while in ...

The safety, security and survivability of mankind are dependent on clean water. Nearly 41% of Earthfs population lives in water]stressed areas, and this will be exacerbated by continuing population growth. To obtain an adequate and sustainable supply of water, it is important to improve already existing methods and develop new and effective technologies for water reuse, reclamation and purific ...

In this Small Business Innovative Research (SBIR) effort, Nikira Labs Inc. proposes to utilize open-path, mid-infrared cavity enhanced absorption spectrometry to develop a sensitive (< 10 ppt), fast (< 100 seconds), and highly-selective ethylene oxide (EtO) analyzer suitable for field-deployment. The US EPA has concluded that EtO, which is widely used in ethylene glycol production and medical ster ...

The proposed device is a compact, portable, and robust battery-powered analytical instrument for monitoring of ultra-low concentrations of various VOCs in complex backgrounds. Our technology is based on principles of analytical gas chromatography (GC), utilizes scrubbed ambient air as carrier gas and a novel highly integrated multisensory platform as a detector. Due to the implementation of a mult ...

Concentrated animal feeding operation (CAFO) is a designation by the U.S. EPA to represent large animal feeding operation with more than 1000 animal units confined on site for more than 45 days during the year. CAFOs emit many volatile organic compounds (VOCs) into the atmosphere. Current multi-gas sensor technologies are not sufficiently portable and are utilized either offline in a lab-setting o ...

Taskforces, utilities, and manufacturers must adapt to contaminants of emerging concern. The most prevalent, persistent, and problematic of these pertinent pollutants are per- and polyfluoroalkyl substances (PFAS). Resource managers need reliable and resilient technologies that convert waste streams to value streams and satisfy regulations. Current state of practice for management of PFAS-laden so ...

Per- and polyfluoroalkyl substances (PFAS) have emerged as a pervasive and persistent threat to drinking water throughout the world. Called ‘forever chemicals” because their high stability leads PFAS to build up in the environment. PFAS accumulates in the blood from exposures and is associated with various cancers and other illnesses. There is an urgent need for a technology that can both remo ...

Per-and polyfluoroalkyl substances (PFAS) have been used extensively since the 1940s due to their chemical stability and unique thermophysical properties. Those same properties make PFAS extremely recalcitrant environmental pollutants, and bioaccumulative toxins. Regulations are rapidly being established by U.S. states, including Michigan, New Hampshire, and New Jersey, beholding municipal water u ...
