| Abstract | The most effective measure for prevention and mitigation of water quality and ecological degradation from eutrophication is the minimization of NO3-N and PO4-P to the standards set out before discharging into waterways. Floating plants can absorb excessive NO3-N and PO4-P from sewage water effectively via their roots for growth. This mechanism supports ecological sustainability, as the result of their natural abundance, well-adaptation and aesthetics in water ecosystem. The experimental design was set up to achieve the objectives of comparing the growths of I. aquatica (water spinach) by fresh biomass experimented in 4 treatments of media growth (NO3-N and PO4-P concentrations at 20 mg-N/L and 1 mg-P/L) with the additions of Z. officinale (ginger rhizome) extracts at 0, 2,000, 4,000, and 6,000 ppm, respectively. Their efficacy of NO3-N and PO4-P removals (%) are analyzed. Analyses of variances (ANOVA) at a confidence level of 95% and Duncan Post Hoc Tests were performed to determine the differences among efficiency of NO3-N and PO4-P removals (%) and growths of I. aquatica. The results revealed that the application of the 4,000 ppm extract was appropriate for I. aquatica growth and the remediation of nutrient-rich waters. This is owing to the highest biomass of 130.08?25.33 g (sig=.015) which was mainly derived from the upper parts (leaves and stems) and the uttermost |
