SNR Process

Sungil Nutrient Removal Process Eco-friendly Water Purification Technology
Through Eco-friendly Constructed
SNR Process (High Efficiency Hybrid Constructed Wetland)

As the influent passes sequentially through an aerobic tank (vertical flow constructed wetland) where air is supplied to maintain an aerobic atmosphere by natural air draft system and an anaerobic/anoxic tank (horizontal flow constructed wetland) where air is not supplied, water purification technology through that simultaneously removes organic matter, nitrogen and phosphorus
