Paper Title
Performance Evaluation of Two Stage Hybrid Constructed Wetland for Treatment Efficiency of Four Different Ratio Proportion Dairy and Municipal Wastewater

Abstract
In the emerging green economy, many of the systems and management techniques that allow for attaining high standards of food security, energy savings, and water purity have a special place of importance set aside for them. With an emphasis on the naturalistic methods of problem solving in particular. Compared to traditional wastewater treatment facilities, constructed wetlands (CWs) offer a more cost-effective, dependable, and environmentally friendly treatment solution. This study used a two-stage experimental setup with a lab-scale, hybrid constructed wetland model that had vertical flow followed by horizontal flow. The first stage vertical flow hybrid constructed wetland reactor had a surface area of 1963.49 cm2, while the second stage horizontal flow hybrid constructed wetland reactor had a surface area of 2025 cm2.The study of performance evaluationdone for four different ratios of dairy and municipal wastewaters in the two stage hybrid constructed wetland reactor.The removal efficiency was improved, when dairy wastewater proportion decreases and municipal wastewater proportion increases. It may be the Canna Indica and Calibanus Hookeries plant which was used and also colddrink plastic bottle chips (CDPBC) used as the substrate media in our study these more suitable for the municipal wastewater and nutrient carried by plant roots, improved the quality of treated water.
