Anua
About
Anua, based in Greensboro, North Carolina, develops and manufactures decentralized wastewater treatment and odor control systems under its 'One Place Water' mission. The company's wastewater division produces peat and coir biofiltration systems — Puraflo Peat and Puraflo Coir — alongside the BioCoir secondary treatment unit, all leveraging natural fiber media for onsite effluent treatment. For higher-flow applications, Anua offers the AeroCell fixed-film aerobic treatment unit, PuraSys sequencing batch reactor (with a Florida-specific variant for state regulatory compliance), PuraMax moving bed biofilm reactor package plant, and the PuraACE and Puralinity advanced treatment units for stringent discharge requirements. EffluaSTEP handles effluent pumping and dispersal. On the odor control side, Anua's Aira product line includes the AiraShell biological biofilter using natural shell media, AiraHybrid combining biological and carbon adsorption, AiraCarb activated carbon adsorber, and AiraSymBIO engineered biofilm scrubber — targeting H2S and volatile organic compounds at municipal lift stations, treatment plants, and food processing facilities. Through affiliated brands Geoflow and SimTech Filter, Anua also provides subsurface drip dispersal and onsite system filtration components. The company serves residential communities, manufactured housing, RV parks, hotels, schools, and commercial developments.
