“…For the removal of organic matter, NH 4 -N and aromatic amines, the aerated wetland reactor outperformed the non-aerated one. The usage of constructed wetland (CW) for dye-rich textile wastewater treatment was carried out under a series of dynamic experiments [103]. The CW model was packed with gravel, sand and zeolite tuff.…”

Dye wastes represent one of the most problematic groups of pollutants because they can be easily identified by the human eye and are not easily biodegradable. This literature review paper highlights and provides an overview of dye waste treatments performed over the three years period from 2008-2010. Noteworthy processes for the treatment of dye waste include biological treatment, catalytic oxidation, filtration, sorption process and combination treatments.

Phytoremediation is an emerging technology that should be considered for the remediation of contaminated sites because of its aesthetic advantages and long-term applicability. The possibility of Scirpus grossus for degradation of a basic dye, methylene blue (MB) was investigated. The effect of the operational parameter of different dye concentrations (0, 200, 400, 600, 800 and 1000 mg/L) was determined, and the water quality parameters namely pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD) and total organic carbon (TOC) were monitored. The UV-Visible absorption confirmed the degradation of MB within 72 days. The removal efficiency of methylene blue dye from synthetic wastewater was determined to be in the range of 86 -38% for all treatments at different concentrations (200 -1000 mg/L) respectively. Furthermore, the highest removals for BOD, COD in 400 mg/L and TOC in 200 mg/L MB were 69, 58 and 63% respectively.

Kesan parameter operasiiaitu kepekatan pewarna yang berbeza (0, 200, 400, 600, 800 dan 1000 mg/L) ditentukan dan parameter kualiti air iaitu pH, oksigen terlarut (DO), permintaan oksigen biokimia (BOD), permintaan oksigen kimia (COD) dan jumlah karbon organic (TOC) dipantau. Penyerapan UV cahaya nampak mengesahkan degradasi MB dalam masa 72 hari. Kecekapan penyingkiran pewarna metilena biru daripada air sisa sintetik telah ditentukan dalam lingkungan 38 -86% untuk semua rawatan dalam kepekatan yang berbeza (200 -1000 mg/L) masing-masing. Tambahan pula, penyingkiran tertinggi bagi BOD, COD dalam 400 mg/L dan TOC dalam 200 mg/L MB masing-masing adalah 69, 58 dan 63%.

Abstract-Textile and leather tannery wastewater pollute water bodies with their content of chromium metal (Cr) and synthetic dyes which are highly toxic. The use of constructed wetland systems is an approach to treat such wastewater before being discharged directly into the environment. This study was conducted to examine the effectiveness of vertical sub-surface downflow constructed wetlands with varying composition in decreasing Cr concentration and color thickness (value) in synthetic textile wastewater. Systems were varied by substrate composition and presence of the plant Leersia hexandra. Synthetic textile wastewater containing K 2 Cr 2 O 7 and reactive dye were flowed downward into five systems: (1) soil-sandgravel substrate, without plants; (2) soil-sand-wood chips substrate, without plants; (3) soil-sand-gravel substrate, and L.hexandra plants; (4) soil-sand-wood chips substrate, and L. hexandra plants; and (5) a system without substrate or plants as control. Chromium concentration and color thickness were measured at 8, 16, 24, 32 and 40 hours after treatment. Measurements at 8 hours showed that systems no. 1, 2, 3, and 4 decreased Cr concentration in effluent as much as 87,6%; 79,1%; 81,4%; and 89,2% respectively. Meanwhile Cr concentration in the control system's effluent remained relatively constant. Systems no. 1, 2, 3, and 4 decolorized the effluent up to 94,6%; 89,6%; 93,4%; and 86,0% respectively; meanwhile, color in the control system was unchanged. All four treatment systems could effectively reduce Cr concentration and color thickness in synthetic textile wastewater. However, results did not support the hypothesis that the presence of plants would significantly affect Cr removal, or that the addition of wood chips to substrate would enhance decolorization effects.
