The Phyto purification is a unique natural and passive treatment system based on Phytotechnology science or the physical and chemical capacity of plant to degrade, assimilate, filter, transform and oxidize substances such as pollutants. This confers the Phyto purification the capacity to handle all the common sewage constituents but also heavy metals, nutrients and micro-pollutants. Offering distinctive aesthetical and environmental characteristics, the Phyto purification is designed to achieve the required level of treatment by selecting the adequate filtering media, plant and configuration.
