As a sustainable and energy-efficient method for wastewater treatment, many researchers have investigated the nitrogen and phosphorus removal capacities of water spinach in aquaculture wastewater remediation (Zheng et al., 2013). These results showed that not only water spinach itself was directly responsible for fraction of the overall nitrogen and phosphorus removal, but also non-plant related components, such as nitrification /denitrification,NH3-volatilization, N-fixation and nutrient uptake by algae, bacteria, or mosquito larva, could play parts of roles in the nutrient removal in such system (Zimmo et al., 2004). Most of research on aquaculture wastewater treatment has focused at laboratory level and such results cannot be directly implemented on large water bodies.
