HIGHER QUALITY OUTPUT
MEETS REGULATIONS
As environmental and health standards tighten and net zero nutrient expectations are embarced, RegenAqua can help with load removal and assist in meeting ultra-low-discharge targets.
PROTECTS WATERWAYS
By reducing nitrogen and phosphorous, tertiary treatment prevents algal blooms, fish kills, and degradation of rivers, lakes, and oceans.
ENABLES BROADER REUSE
RegenAqua treated water is suitable for reuse in crop irrigation, municipal landscaping, industrial reuse, and inland river discharge.
