DYE WASTEWATER TREATMENT: REMOVAL OF REACTIVE DYESUSING
Wastewater treatment in textile and dye industry mainly involves treatment of highly colored wastewater containing variety of dyes in different concentrations. The wastewater needs to be treated prior to discharge by effectively removing dye color in order to protect environment and as per the statutory guidelines. Coagulation is the most commonly used method in the treatment of textile
the potential use of sugarcane bagasse for the removal of dyes from wastewater has been discussed. Dyes are usually present in trace quantities in the treated effluents of many industries. The effectiveness of adsorption for dye removal from wastewaters has made it an ideal alternative to other expensive treatment methods.
China Textile Reactive Dyes Wastewater Color Removal
Dyes, Reactive Dye, Textile Reactive Dyes manufacturer / supplier in China, offering Textile Reactive Dyes Wastewater Color Removal, Polyamine Disinfector for Water Treatment Plant, Polyamine Work as Sanitizer for Water Treatment and so on.
The flocculant was tested for synthetic wastewater containing four model reactive dyes (Black 5, Blue 2, Red 2 and Yellow 2) and real wastewater containing reactive dyes from a local dyeing industry. For the synthetic wastewater, the use of inorganic coagulant (1 g/L) alone achieved only 20% of color removal or less.
Removal of Dyes from Wastewater Using Flyash, a Low-Cost
The use of low-cost adsorbent has been investigated as a replacement for the current expensive methods of removing dyes from wastewater. As such, fly ash generated in National Thermal Power plant was collected and converted into a low-cost adsorbent. The prepared adsorbent was characterized and used for the removal of dyes from wastewater.
Konsowa et al. (2013) investigated the treatment of textile wastewater using aerobic MBR process, where the COD and dye (red dye-C81) removal efficiencies reached at 95% and 90%, respectively, for a HRT of 24 h. Deowan et al. (2013) studied textile dye wastewater treatment by MBR process. It was found that the COD, red, and blue color removal
Removal of dyes using agricultural waste as low-cost
Color removal from wastewater has been a matter of concern, both in the aesthetic sense and health point of view. Color removal from textile effluents on a continuous industrial scale has been given much attention in the last few years, not only because of its potential toxicity, but also mainly due to its visibility problem. There have been various promising techniques for the removal of dyes

Synthetic reactive dye wastewater treatment by using nano
In this study, application of polyamide nano-membrane to remove dyes was evaluated for five different fiber reactive dyes’ wastewater, namely reactive blue 15, reactive red 194, reactive yellow 145, reactive black 5, and reactive orange 16. The discussed dyes were tested in low concentration (16 mg/l) during a 60 min filtration process.

equalization tank of textile treatment plant of a dye mill in Kuantan, Pahang, Malaysia. The reactive dyes contained in the textile wastewater were Remazol Black B (RBB), Remazol Brilliant Blue R (RBBR), and Remazol Brilliant Red F3B (RBRF3B). The structures of these reactive dyes are shown in Figure 1 (a), (b), and (c).
- Can cationic polyacrylamide be used in oilfield wastewater treatment?
- Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
- What is organic polymer flocculant cationic polyacrylamide (CPAM)?
- The organic polymer flocculant cationic polyacrylamide (CPAM) has the characteristics of a low additive amount, good turbidity removal and water purification effect, and high COD removal efficiency, and it has become the most commonly used polymer flocculant in the oilfield wastewater treatment process [ 11, 12, 13, 14, 15 ].
