APTwater's ARoNite™ process is a hydrogen-based biological treatment system for the removal of nitrates and other oxidized contaminants from agriculturally impaired drinking water supplies.
The ARoNite (Autotrophic Reduction of Nitrate) process is a fixed-film biological treatment technology for the biochemical removal of oxidized contaminants. ARoNite systems rely on a naturally occurring culture that uses hydrogen gas as an electron donor which biochemically reduces and metabolizes contaminants in the influent stream.
The autotrophic biology takes carbon from the influent stream and completely eliminates brine streams or other waste residuals. The resulting process is extremely tolerant of variations in feed water quality and produces consistently high quality effluent. ARoNite systems also embody sustainable design. The process is based on renewable inputs and completely eliminates brine streams or other waste residuals.
A unique feature of the ARoNite process is its use of hydrogen to support a beneficial biofilm. To maximize performance and assure process safety, ARoNite systems use a specially designed sealed growth media which diffuses hydrogen gas directly to the biology. As a result, hydrogen is used at near stoichiometric rates. Because volumes are so low, hydrogen can be produced onsite and on-demand, completely eliminating issues with gas handling and storage. Most importantly, the entire process is fully automated to minimize operations and maintenance.
The hydrogen-based biological treatment system uses little energy and produces minimal waste. As a result, ARoNite systems do not present owners with the permitting, cost, and complexity issues associated with brine handling and disposal. The low volume of waste sludge produced by the ARoNite process is non-toxic and suitable for use as an environmentally friendly soil amendment after drying.
