Assessment of the dye removal capability of submersed aquatic plants in a laboratory-scale wetland system using anova

Abstract

-The textile dye (Basic Blue 41(BB41)) removal capability of a laboratory-scale wetland system was presented in this study. Twenty glass aquaria were used to establish the wetland. Myriophyllum spicatum and Ceratophyllum demersum were planted in the aquaria and acclimated. After establishing flow conditions, the aquaria were fed with synthetic wastewaters containing BB41. The concentration of the dye was adjusted to 11.0 mg/L in the synthetic wastewater. Hydraulic retention times (HRTs) ranged between 3 and 18 days. Effective HRTs were 9 and 18 days. The highest dye removal rates were 94.8 and 94.1% for M. spicatum and C. demersum aquaria respectively. The statistical ANOVA method was used to assess the dye removal capability of the wetland system. In all cases the ANOVA method revealed that plants in the wetland system and HRT were important factors and the wetland system was able to remove the dye from influent wastewater.

Textile dye wastewater characteristics and constituents of synthetic effluents: a critical review

“…Mbuligwe (2005) provided a new constituent with a COD concentration lower than the typical values. However, the constituent reported by Keskinkan and Göksu (2007) contained low chemical concentrations using the hydroponic Arnon-Hoagland nutrient solution after dilution. Submerged plants were suitable for Table 7 Proposed recipe simulating the textile effluents a 1 ml of the trace element stock solution added to each 1 L of the ingredients mixture above, as proposed by Muda et al (2010) Chemical treatment by this constituent.…”

The mixture contained 11 mg/l of the dye with 5% Arnon-Hoagland nutrients, which included chemicals such as potassium nitrate, calcium nitrate, ammonium dihydrogen phosphate, magnesium sulphate heptahydrate, boric acid, manganese(II) chloride Ojstršek et al (2007) operated two CW systems: one consisting of four substrate layers (gravel, sand, zeolite and peat) and another one without peat for the treatment of three dye bath wastewaters.…”

Enhanced bioremoval of refractory compounds from dyeing wastewater using optimized sequential anaerobic/aerobic process

“…3 Effect of HRT on a color, b SCOD, and c SBOD removal in the UASB reactor anaerobic reactors is generally a slow process, which requires long HRTs to reach a satisfactory extent of color removal (Li et al 2009). Keskinkan and Lugal Göksu (2007) also stated that the variation in HRT is an important factor in dye treatment and the treatment performance increased with the increasing HRT in their study. Rodrigues da Silva et al (2012) also observed that a short HRT (3 h) was not sufficient to allow a higher decolorization, suggesting that a short HRT was not long enough to allow the dye reduction satisfactory.…”
