Constructed wetlands (aka engineered wetlands) provide natural treatment of industrial wastewater and landfill leachate. These are lined systems, protective of the environment, that mimic the steps found in more traditional wastewater treatment processes. The main difference is the trade-off of energy (labor, electricity, chemicals) in a traditional system for space, and the retention time of a wetland.
Types of constructed wetlands include vertical or horizontal subsurface flow, free water surface flow, and floating systems. Our wetlands are engineered for site-specific conditions and could include a combination of treatment stages depending on the contaminants.
Contrary to common belief, constructed wetland systems can be effective in cold-weather climates as demonstrated by numerous systems operating as designed in areas such as Minnesota and Canada.
Wetland systems are a proven option for ammonia and TKN removal to eliminate POTW surcharges and/or avoid cutoff due to nitrogen loading, and also for other contaminants. Please inquire to learn where this approach can help solve your discharge problems.
