Rapid industrialization is one of the intricate factors that is linked to the depletion of water resources and increased generation of wastewater. Due to various obstructions and impediments, such as ineffective treatment solutions, exorbitant prices, lack of basic amenities, insufficient financial assistance, and technical expertise, sustainable treatment of industrial effluents has become an onerous process in most parts of the world. The majority of current treatment solutions are conventional and outdated, and thus fall short to remove all the contaminants efficiently from the industrial wastewater. Moreover, poorly treated or untreated industrial effluents are indiscriminately dumped into water bodies such as lakes, ponds, and rivers, causing substantial health hazards to humans and animals and serious threats to the aquatic ecosystem. Thus, there is a need for highly efficient, cost-effective, and sustainable technologies for the treatment of industrial wastewater. Employment of microbial technologies such as microbial fuel cells and microalgal technologies, treatment of wastewater can be coupled with the production of bioelectricity and valuable biomass, respectively. Moreover, with nanofiltration and biochar technologies, the efficiency of the overall treatment procedure can be increased to a greater extent. The present review aims to highlight opportunities and challenges associated with some of the emerging trends in industrial wastewater research.

Dyes are substances that enhance the appearance of finished goods by providing uniform colour. Dyeing is the application process of dyes that are fixed in textile fibers. The dyeing process uses various steps, including pre-treatment, desizing, scouring, bleaching, carbonizing, degumming, and mercerization. Water is considered the primary medium for applying dyes and other chemicals for this treatment in the dyeing process. The dyeing process contains many toxic chemicals, metals and non-soluble substances, such as wastewater, which is thrown into the environment. It is noted that, during dyeing , around 50-300 liters of water is required for 1 kg of fiber. On the other hand, 1-2 million liters of water are needed every day for 50,000 meters of daily production. This massive amount of toxic wastewater is highly harmful to the environment, human health, aquatic system, soil, air, water, plants, and animals. This review paper states various dyeing processes with different dyes, including acid dye, direct dye, sulfur dye, reactive dye, vat dye, metal complex dye, azo dye, disperse dye, and basic dye. In contrast, it also describes the influencing factors of dyeing processes and methods. Moreover, this review demonstrates the impacts of textile dyes on the environment (water, soil, air emissions, human health) and illustrates possible remedial actions regarding wastewater.

Now-a-days nanotechnology is one of the booming fields for the researchers. With the increase in industrialization mainly textile, paper, medicine, plastic industry, there is an increase in concentration of organic dyes as pollutant. Release of harmful dyes in water bodies has become a serious issue, as most of the dyes are carcinogenic and mutagenic in nature and causes various diseases. Therefore, there is a requirement to find out new approaches for efficient treatment of effluent containing dyes. Nanoparticles are one of the potential solutions to this problem. They can be synthesized from different methods, however synthesis of nanoparticles from different plant parts (leaf, root or stem extract) is economical as well as ecofriendly. Phytogenic nanoparticles have various environmental applications and one of them is remediation of dyes. The aim of this review is to provide an overview of last five years studies about catalytic and photocatalytic degradation of various harmful dyes by plant synthesized nanoparticles, mechanism of degradation and advantages and disadvantages of phytogenic synthesis.
