Constructed Treatment Wetlands (CTWs) are currently being used worldwide for efficient and cost-effective treatment of a variety of wastewater effluents with complex contaminants
(e.g., BTEX, PAHs, metals, and CVOCs). Roux has been actively involved in developing and applying CTW technology since 1993. Our use of carefully selected media, sequencing, and passive hydraulic controls have resulted in state-of-the-science 4th generation designs that are cost-effective, reliable, and sustainable even under extreme environmental conditions. Our Treatment Wetlands have saved clients millions of dollars over conventional treatment systems. We assist our clients with concept development, engineering design, construction, performance monitoring, and operation and maintenance.
