Reciprocating Constructed Wetlands for Treating High Strength Anaerobic Lagoon Wastewater

Innovative wastewater treatment systems are needed for removing nutrients, noxious odors, dissolved organic matter, and pathogens from high strength agricultural and processing wastewater. A novel reciprocating subsurface-flow constructed wetland, consisting of four cells totaling 3570 m (1.5 m deep), has been treating anaerobic lagoon wastewater from a commercial-scale confined swine feeding o...

Reciprocating constructed wetlands for treating industrial, municipal and agricultural wastewater.

Scientists at the Tennessee Valley Authority (TVA), and in collaboration with the U.S. Environmental Protection Agency (EPA), are continuing to develop and refine an innovative wastewater treatment system referred to as reciprocating subsurface-flow constructed wetlands. Reciprocation relates to patented improvements in the design and operation of paired subsurface-flow constructed wetlands, su...

Applications of Constructed Wetlands for Wastewater Treatment

During the past decades, the high cost of conventional treatment processes has produced much economic pressure and they are not as natural methods as we expected. Thus, engineers begin to search for some creative, cost effective, and environmentally sound ways to treat wastewaters. Constructed wetland is a man made system which provides us many benefits and it is a very attractive way for many ...

Constructed Wetlands for Wastewater Treatment: A Review

The first experiments on the use of wetland plants to treat wastewaters were carried out in the early 1950s by Dr. Käthe Seidel in Germany. The first full scale systems were put in operation during the late 1960s and since then constructed wetland systems have been spreading throughout the world. At present, there are several types of constructed wetlands used for wastewater treatment. Free wat...
