Effectiveness of domestic wastewater treatment using floating rafts a promising phyto-remedial approach: A review

Treatment of wastewater will lead to the problems again, if we will not use new more efficient alternative technologies/methods to avoid drawback of old technologies. Loss of water can be reduced through application of easy, inexpensive and eco-friendly technologies for wastewater treatment. Using Floating rafts to purify polluted wastewater is a process/method of ecological restoration at in-situ, as well as a complicated physical (attachment of pollutants to the root surface), chemical (degradation of metals into less toxic form) and biological process (microbial processes). Its core is utilizing aquatic plants such as Canna and Water lily and root attached microbes such as bac-teria, fungi and algae to absorb pollutants such as nitrogen and phosphorus, degrade organic matter and accumulates heavy metals in their biomass. Phytoremediation of polluted wastewater using the Floating rafts technique is an Eco-friendly method of wastewater treatment, which is economically effective to construct, requires little maintenance and increase the biodiversity as different types of plants are used. Floating rafts technique has been applied to some water pollution control projects at domestic and abroad. However, there are some factors such as plants, temperature, seasons, hydraulic retention time, coverage and initial concentration of pollutants etc. influenced to the pollutants removal efficiency of Floating rafts. In the future, the development orientation has been subjected to plant and its combinations, the transformation of Floating rafts structure and the utilization of aquatic plants, and probed the technology of Floating rafts building and management, to implement the win-win of landscape benefit and ecological function

Treatment of Sewage (Domestic Wastewater or Municipal Wastewater) and Electricity Production by Integrating Constructed Wetland with Microbial Fuel Cell

Proper treatment of wastewater is important to human health and societal development, and the commonly applied wastewater treatment technologies based on aerobic treatment have a significant demand for energy. Thus, new treatment technologies with low energy consumption and possible recovery of valuable resources (e.g., energy and water) from wastewater become of strong interest. Among the newly developed concepts, microbial fuel cells (MFCs) integrated with constructed wetland appear to be very attractive because of direct electricity generation from organic compounds and treatment of wastewater. Constructed wetland coupled with microbial fuel cell (CW-MFC) is an emerging technology in recent years and has attracted a lot of attention from researchers in the fields of wastewater treatment and bioenergy production. CW-MFC is a promising technology in the fields of wastewater treatment and bioenergy. However, at current power levels, the advantage of combining the two is mainly because of the enhancement of wastewater treatment in anaerobic zones within the wetland. New operational strategies need to be explored to increase and utilize electricity output

Floating Raft Wastewater Treatment System: A Review

Recently more imbalances are observed in availability and quality of natural resources such as water, which is most precious as well as playing a vital role in the governance of entire natural as well as manmade ecosystem. Hence, the presence of water in good quality is extremely necessary for overall sustainable and eco-friendly development. The floating raft wastewater treatment system is most emerging sustainable and plant-based-eco-friendly method for wastewater treatment since it is totally plant based and there is no more initial requirement of inputs as well as there is no production of harmful by-products into the environment
