“…Treatments indicated with different letters are significantly different (Mann-Whitney U tests, a = 0.05). planted with Typha have been studied by Hubbard et al (2004) and Weragoda et al (2012), but neither study mentioned suboptimal plant health/growth. The life cycles of Typha and Iris are similar, i.e., they are both herbaceous perennial plants that grow and bloom during spring and summer, die back every autumn/winter, and then grow again from their rootstock in spring.…”

“…The main applications of FTWs in terms of water quality improvement include the treatment of storm water, sewage, pond water, urban lake water, dairy manure effluent, and water supply reservoirs (Weragoda et al, 2012). A high number of studies have provided nutrient removal efficiencies for FTWs (e.g., Revitt et al, 1997;De Stefani et al, 2011;Vymazal, 2007).…”

“…Song et al [34] reported 70.4% BOD reduction on municipal wastewater treatment in China, with Phragmites australis and Typha orientalis. Weragoda et al [51] reported 65.5% BOD reduction for municipal wastewater treatment in Seri Lanka, with Typha angustifolia and Canna iridiflora. Mburu et al [46] used Typha angustifolia and Canna iridiflora, in order to treat municipal wastewater, in Seri Lanka; they reported 65.5% BOD reduction.…”

Palm oil mill effluent (POME), a pollutant produced by the palm oil industry, was treated by the Vetiver system technology (VST). This technology was applied for the first time to treat POME in order to decrease biochemical oxygen demand (BOD) and chemical oxygen demand (COD). In this study, two different concentrations of POME (low and high) were treated with Vetiver plants for 2 weeks. The results showed that Vetiver was able to reduce the BOD up to 90% in low concentration POME and 60% in high concentration POME, while control sets (without plant) only was able to reduce 15% of BOD. The COD reduction was 94% in low concentration POME and 39% in high concentration POME, while control just shows reduction of 12%. Morphologically, maximum root and shoot lengths were 70 cm, the number of tillers and leaves was 344 and 86, and biomass production was 4.1 kg m−2. These results showed that VST was effective in reducing BOD and COD in POME. The treatment in low concentration was superior to the high concentration. Furthermore, biomass of plant can be considered as a promising raw material for biofuel production while high amount of biomass was generated in low concentration of POME.

Liquid waste of tofu production has a high content of organic matter which can lead to a decrease in water quality. This study was aimed to obtain an optimal combination of duration and waste concentration in tofu liquid waste treatment using Chrysopogon zizanioides. Response surface method using Design Expert 7.0 software was applied to optimize combination response of duration (3, 9, 15 days) and waste concentration (20, 40, 60%), aided by Design Expert 7.0 software. The optimum treatment was 15 days with 20% waste concentration, reducing 55.48% of COD, 37.86% BOD, 93.51% TSS, 87.86% Turbidity, increasing DO to 7.2 mg/L and pH to 7.2.
