“…It uses the metabolism of microorganisms to convert soluble or insoluble organic matter in sewage into non-threatening substances. There are many types of microorganisms but the individuals are so small that they cannot be recognized by the naked eye, and can rapidly multiply during growth [9][10][11]. Only by understanding and mastering the different characteristics of different microorganisms can we cultivate microorganisms in the sewage treatment process to obtain better purification of sewage.…”

“…Maximum removal efficiencies of 80 and 78%, 81 and 82%, 63 and 69%, and 79 and 89% were reported for chemical oxygen demand (COD), biological oxygen demand (BOD), total Kjeldahl nitrogen (TKN), and total suspended solids (TSS) for batch and continuous systems, respectively. Yadav, Chazarenc, and Mutnuri (2018) studied a twostage VFCW system to treat single household raw wastewater under tropical climate. The removal efficiencies for COD, BOD, TKN, ammoniacal nitrogen (NH 3 -N), total phosphorus (TP), total dissolved solid (TDS), and total volatile solids (TVS) in the 1st stage were 64%, 65%, 15%, 21%, 34%, and 54%, respectively, and those in the second-stage reactor were 90%, 88%, 50%, 52%, 58%, and 71%, respectively.…”

This article presents an update on the research and practical demonstration of wetland treatment technologies for wastewater treatment. Applications of wetlands in wastewater treatment (as an advanced treatment unit or a decentralized system) and stormwater management or treatment for nutrient and pollutant removal (metals, industrial and emerging pollutants including pharmaceutical compounds and pathogens) are highlighted. A summary of studies involving the effects of vegetation, wetland design and operation, and configurations for efficient treatment of various municipal and industrial wastewaters is also included.

“…Canna lily has a large root system and strong enough to absorb organic matter, therefore, Canna lily can absorb more nutrients for growth and store the excess nutrient in its tissue than other aquatic plants (Yadav, Chazarenc, & Mutnuri, 2018). CWs system operating as standalone technologies are in some cases unable to meet the requirements of these new guidelines despite improvements in design and operational strategies and the utilization of intensified systems such as flow direction reciprocation, artificial aeration, tidal flow CWs (Haritash, Duta, & Sharma, 2017).…”

The application of sewage treatment in New Delhi should implement the treatment processes, which are easy to be operated and is not costly operational and avoid the complexity of the operating system of STP. The renewed interest in alternative onsite treatment technology by using a constructed wetland (CW). Canna lily, an ornamental plant that has an aesthetic value, is very suitable for an alternative plant for a constructed wetland. This study aims to observe the ability of canna lily for phytotechnology implementation in a constructed wetland. This study is known as a range-finding test (RFT), which served as a preliminary test. Observation is conducted by preparing variation concentration of wastewater; 25%; 50%; 75%; 100% and 0% as control, which was injected into the wetland. CW (60 cm long, 60 cm wide and 60 cm deep) contained gravel medium height 25 cm with a wastewater volume 3 L. Observation measured the height of the plant, the color of the leaf, and DO, and BOD concentration. The observation was conducted for about 25 days, in term of 15 days for range finding test and 10 days for acclimation. The results show that Canna lily could grow well, though it has some part of the withered leaf, reach height significantly, and indicated decreasing concentration of organic parameters. It is conjectured that Canna lily is very possible for a constructed wetland application.
