Reliable Contaminant Removal Through Engineered Biological Processes

Biological Filtration

Pureflow biological filtration systems utilize naturally occurring biological processes to provide effective and sustainable removal of dissolved constituents. These systems are engineered for long media life, low chemical consumption, and stable performance, making them well suited for municipal and industrial groundwater applications. Each system is custom designed to meet site‑specific water quality objectives while minimizing operator attention and lifecycle cost.

Ozone/BAC Systems

Pureflow O₃/BAC systems combine ozone oxidation with biologically activated carbon filtration to deliver a robust, multi-barrier treatment solution. Ozone breaks down complex organics, micropollutants, and pathogens into biodegradable compounds, enhancing downstream biologically activated carbon performance.
