Abstract
Wetlands have traditionally functioned as a natural filtration system. Constructed wetlands (CWs) are a cost-effective and efficient green technology for treating many different types of wastewaters. The efficiency of constructed wetland depends upon the type of media, vegetation, effluent concentration, and applied hydraulic load. The objective of the present paper is to Development and Design a laboratory scale constructed wetland system. The important considerations in the design are the size of the wetland, aspect ratio, depth of each layer, and slope. The length, width, and height of the CWs are 1.2 m; 0.3 m; and 0.65 m; respectively. The total volume of CWs is 0.234 m3 and the treatment section in the system consists volume of 0.135 m3. Twelve sampling points are provided to collect the water from the different layers (media) of the wetland. An aeration pipe is provided at the bottom of CWs. With the laboratory scale constructed wetland system, we can analyze the different types of wastewater.
