Wetlands constitute a vital source of habitat life for both people and wildlife by enhancing our standard of living and providing shelter to wildlife. Wetlands served as the foundation for both basic and complex discoveries. For instance, papyrus was used to make paper and ships, while dried reeds were used to build houses. Wetlands provided a range of economic and life-sustaining resources; therefore, early civilisations frequently developed around marshes and rivers. In ancient times, wetlands were used for wastewater treatment as a sustainable technology.. Constructed wetlands have been used to treat wastewater for more than five decades. The idea of using constructed wetlands for wastewater treatment emerged from the observation of natural wetlands’ ability to filter and purify water, inspiring the design of artificial systems that mimic these ecological processes. Constructed wetlands have traditionally been used to treat residential or municipal wastewater, they are currently successfully used to treat a range of wastewater treatment processes, including the wastewater from wineries, dairies, and textile mills, and many other industries. Our water resources are on the verge of danger due to the disposal of untreated wastewater from the industries located around the water bodies. On the other hand, constructed wetlands (CWs) are of the unimpeded water surface flow type or the type of subsurface flow, are natural treatment systems that without the aid of mechanical or energy-intensive machinery, stabilize waste through the actions of bacteria, media, or plants. Conventional wastewater treatment methods have some drawbacks like high energy consumption, formation of disinfection by-products, create environmental impacts, and concentrate disposal and limited treatment capacity. Therefore, the creation and maintenance of the artificial wetlands should be tailored to the specific pollutants of concern for optimal treatment performance. Industrial wastewater has been constructed wetlands that were treated employing both surface and subsurface flow. For subsurface flow created wetlands, both horizontal and vertical flow systems have been devised. It has also been claimed that other hybrid built wetlands have been used to cleanse industrial wastewater. However, vertical flow built wetlands are quite effective at treating a variety of wastewater pollutants.
