“…Also large number of microorganisms are available which are easy to maintain and also require low preparation (Crini and Lichtfouse, 2018). Apart from these dye degradation techniques periphyton biofilm or periphytic biofilm system can be also used for degradation of dyes (Li and Bishop 2004;Shabbir et al, 2017a;Shabbir et al, 2017b;Pandey and Bergey, 2018;Dias et al, 2019;Shabbir et al, 2020). Among various activities of dye industries, dye manufacturing is the main source of environmental pollution due to release of hazardous dye in water bodies.…”

Industrialization increases use of dyes due to its high demand in paper, cosmetic, textile, leather and food industries. This in turn would increase wastewater generation from dye industrial activities. Various dyes and its structural compounds present in dye industrial wastewater have harmful effects on plants, animals and humans. Synthetic dyes are more resistant than natural dyes to physical and chemical methods for remediation which makes them more difficult to get decolorize. Microbial degradation has been researched and reviewed largely for quicker dye degradation. Genetically engineered microorganisms (GEMs) play important role in achieving complete dye degradation. This paper provides scientific and technical information about dyes & dye intermediates and biodegradation of azo dye. It also compiles information about factors affecting dye(s) biodegradation, role of genetically modified organisms (GMOs) in process of dye(s) degradation and perspectives in this field of research.

“…Many techniques have been developed for the treatment of dyebearing effluents including ion exchange [12], chemical precipitation [13], coagulation/ flocculation [14,15], ozonation [16], membrane filtration [17], solvent extraction [18], and photocatalytic degradation [19]. The implementation of these sophisticated strategies frequently faces important drawbacks and constraints such as high operational cost, inefficiency for low pollutant concentrations, toxic intermediates products, reagents consumption, or sewage sludge formation.…”

“…Such toxicity can affect not only dye removal but also other biochemical processes within the MBBR, such as nitrogen removal. While Castro et al [15] reported that no long-term inhibition of nitrifiers was observed after feeding an aerobic MBBR with ozonated RO16 solutions in concentrations of up to 500 mg/L, Dias et al [22] observed a completely opposite behavior for RR239: its ozonation products disturbed the activity of nitrifying bacteria, completely inhibiting nitratation, at much lower dye concentrations (50 mg/L). Furthermore, nitrifiers did not seem to adapt to the presence of RR 239 ozonation products, since ammonium removal remained low (41%), even after 90 days of reactor operation.…”

“…Among the studies published so far, most of them were conducted on a laboratory or pilot scale, with synthetic wastewater simulating a real scenario used to feed the bioreactors. Process associations have also been investigated, such as ozonation + aerobic MBBR [14,15,21,22,27,59], Fenton or photo-Fenton + MBBR [3,72], anaerobic MBBR + aerobic MBBR [23,27,39,55,68], upflow anaerobic sludge blanket (UASB) + MBBR [48], photo-rotating biological contactor (PRBC) + aerobic MBBR [80], granular-activated carbon bed (GAC) + MBBR [76].…”

Dye-containing wastewaters are produced in large quantities worldwide. The bright colors they provide, associated with their potential toxicity, carcinogenicity, and mutagenicity, consist of environmental threats. Therefore, remediation of these waste streams is essential. However, the low biodegradability shown by these compounds constitutes an obstacle to the application of effective and low-cost conventional biological wastewater treatment systems. In this context, other advanced biofilm technologies, such as the moving bed biofilm reactor (MBBR), may consist in an economically viable and eco-friendly alternative for achieving high removal of dyes, while also reaching high performance in the concomitant degradation of other pollutants, such as organic matter and nutrients. In this chapter, the MBBR technology is briefly explained, and recent investigations on the treatment of dyecontaining wastewaters by this biofilm process are described. Moreover, the most influential operational parameters for color removal improvement are discussed. The use of sequential reactors in multistage processes and the association of MBBR with other technologies are also evaluated. Finally, the kinetics of dye degradation in MBBR is presented. Few studies were found in the literature on the application of MBBR for dye removal, mainly consisting of lab-scale or pilot-scale investigations. A single MBBR as a stand-alone technology does not seem to achieve complete dye mineralization. Nonetheless, the use of a series of MBBR or their combination with other physicochemical or biological processes seems to be a good alternative for dyes remediation. It is clear that more studies on MBBR process optimization are needed, especially for real dye-containing wastewaters, to guarantee the effectiveness and sustainability of large-scale treatment plants.
