“…Ion-exchange adsorbents are introduced in the wastewater in either solid or liquid form, they are used to bind harmful anions or cations of the opposite charge, and in turn, release an equivalent amount of non-harmful hydrogen ions [89,90]. The review paper of Hassan and Carr [180] addressed strategies for reactive dye removal by applying the ion-exchange method [180][181][182]. Cationic dyes were also removed from water throughout the ion-exchange method [183,184].…”

Natural dyes have been used from ancient times for multiple purposes, most importantly in the field of textile dying. The increasing demand and excessive costs of natural dye extraction engendered the discovery of synthetic dyes from petrochemical compounds. Nowadays, they are dominating the textile market, with nearly 8 × 105 tons produced per year due to their wide range of color pigments and consistent coloration. Textile industries consume huge amounts of water in the dyeing processes, making it hard to treat the enormous quantities of this hazardous wastewater. Thus, they have harmful impacts when discharged in non-treated or partially treated forms in the environment (air, soil, plants and water), causing several human diseases. In the present work we focused on synthetic dyes. We started by studying their classification which depended on the nature of the manufactured fiber (cellulose, protein and synthetic fiber dyes). Then, we mentioned the characteristics of synthetic dyes, however, we focused more on their negative impacts on the ecosystem (soil, plants, water and air) and on humans. Lastly, we discussed the applied physical, chemical and biological strategies solely or in combination for textile dye wastewater treatments. Additionally, we described the newly established nanotechnology which achieves complete discharge decontamination.

“…Few studies have focused on the growth stages of biofilms of solid carbon source carriers, which are crucial to understanding the impact of biofilms on wastewater treatment [ 14 , 28 , 32 , 33 , 34 ]. Figure 5 shows the growth trend of bacterial biofilms on carrier-PLA-cavity and naked-carrier.…”

A novel method was used to fabricate the bio-carrier with both a high specific surface area and good compatibility. The results of monitoring the growth of biofilms at a low C/N ratio (0.83) showed that resulting carrier-PLA-cavity offered certain advantages for biofilm growth by providing an appropriate microenvironment for bacterial growth in wastewater treatment. The biofilm on carrier-PLA-cavity grew and updated faster than the naked-carrier. The biomass and thickness of biofilms growing on carrier-PLA-cavity were 10 kg/m3 and 500 μm, respectively. From the wastewater tests, 90% of the total nitrogen was removed via simultaneous nitrification and denitrification (SND) by the biofilm biomass attached to carrier-PLA-cavity, compared to 68% for the naked-carrier. The COD removal efficiency values of the carrier-PLA-cavity and naked-carrier were 94% and 86%, respectively. The microbial community analysis of carrier biofilms showed that Halomonas was the most abundant genus, and heterotrophic nitrification and denitrification were responsible for nitrogen removal in both reactors. Notably, this method does not require any complicated equipment or structural design. This novel method might be a promising strategy for fabricating biocarriers for treating wastewater with a low C/N ratio.

“…(2020) achieved >99% and 95–97% removal of colour and high COD, respectively, by using anaerobic DMBR fabricated with nylon mesh support substrate with distinct pore sizes (20, 53 and 100 μ m) at fluxes of 5–15 l (m 2 h) −1 (LMH), which was remarkably higher than traditional AnMBRs integrated with micro/ultra‐filtration membranes (Yurtsever et al . 2020).…”

In the recent past, wastewater treatment processes perform a pivotal role in accordance to maintain the sustainable environment and health of mankind at a proper hygiene level. It has proven as indispensable by government regulations throughout the world due to the importance of preserving freshwater bodies. Human activities, predominantly from industrial sectors, generate an immeasurable amount of industrial wastewater loaded with toxic chemicals, which not only cause dreadful environmental problems but also leave harmful impacts on public health. Hence, industrial wastewater effluent must be treated before releasing into the environment to restrain the problems related to industrial wastewater discharge to the environment. Nowadays, biological wastewater treatment methods have been considered as an excellent approach for industrial wastewater treatment process because of their cost-effectiveness in the treatment, high efficiency, and their potential to counteract the drawbacks of conventional wastewater treatment methods. Recently, the treatment of industrial effluent through bioreactor has proven as one of the best methods from the presently available methods. Reactors are the principle part of any biotechnology-based method for microbial or enzymatic biodegradation, biotransformation, and bioremediation. This review aims to explore and compile the assessment of the most appropriate reactors, like, packed bed reactor, membrane bioreactor, rotating biological contactor, up-flow anaerobic sludge blanket reactor, photobioreactor, biological fluidized bed reactor, continuous stirred tank bioreactor, etc. that are extensively used for distinct industrial wastewater treatment.
