APPLICATION OF PLANTS IN CONSTRUCTED WETLANDS IN SRI LANKA - A MINI-REVIEW | Journal of Global ....

Green technologies are widely used for wastewater treatment in various nations across the world. Constructed Wetland (CW) technology is one such environmentally friendly wastewater treatment method that has been used for decades around the world. Despite the fact that this technology appears to be a relatively new technology in Sri Lanka in scientific literature, there is substantial historical evidence for the use of plant-based comparatively similar technologies for contaminated water remediation in ancient times. While there is now no sound written document available in Sri Lanka that contains a list of plant species that have been applied for CWs. As a result, the primary goal of this paper was to compile a list of plant species that have been used in Sri Lankan Constructed Wetlands. Furthermore, this list is intended to give researchers an overview of prospective plants at a glance when choosing plant species for future CW research. When creating this work, the collected literature was subjected to a critical desktop examination. More than fifty plant species have been employed in CWs in Sri Lanka since early civilisation, according to this review of published and unpublished literature. In addition, roughly thirty studies on CW have been undertaken in Sri Lanka. Despite the paucity of study on CWs in Sri Lanka, this paper advises that when choosing plants for CW studies, researchers should concentrate on locally available plant species with high nutrient removal efficiencies. New scientific concepts such as integrated floating wetlands, green roofs, and urban ecosystems should include more native plant species.
