SENTRY and has pioneered a biology activity and water quality monitoring platform that provides real-time microbial performance data in locations never possible before. From untreated, variable wastewater at a treatment plant’ headworks (consumable BOD) to fluctuating anaerobic digester (AD) biomass (consumable VFA), our robust bio-electrode sensors provide early-on, always-on insights into biological processes that exist wherever water is used, stored, or treated.
