Treatment of the Influent Sewage from Stp Davangere Town from Vertical Flow Artificial Wetland using Colocasia Esculenta Plant

Year: 2024

Type: article

Abstract: An artificial vertical flow constructed wetland (AVCW) system which is a subsurface flow is used in sewage treatment plants (STPs) to treat influent sewage by which is a mixture of organic and inorganic waste, chemicals, microbes, and nutrients. The Colocasia esculenta (elephant ears) plant species is used as the pollution removal test plant for the hydraulic retention time (HRT)of 28 days. The test plant has removed the parameters Total dissolved solids (50%), Total suspended solids (27%), Biological Oxygen Demand (54.30%), Chemical Oxygen Demand (58%), Ammonia- Nitrogen (59.48%) and Ortho- Phosphate (46.99%). pH is reduced and Dissolved Oxygen is increased during the period of 28 days hydraulic retention time (HRT). Treated sample is analyzed with an interval of 7 days during HRT is checked for the various parameters listed above. It shows that C. esculenta is better option for nutrient absorption in the artificial wetland (AW) systems, providing very economical and environmentally friendly method of treating wastewater (WW), especially in the decentralized systems and the results indicate that C. esculenta is viable options for enhancing the WW quality in STP effluent.
