“…The major pollutants in textile effluents usually have higher turbidity, color, and toxic chemicals (Thiruppathi et al, 2021). Dyes are toxic, can cause skin irritation, and are catastrophic to the ecosystem (Jadhav & Jadhav, 2021). Additionally, the treatment and reutilization of textile wastewater is hindered by the fact that intricate technologies involving adsorption, flocculation, and so forth have low efficiency rates, high costs, and complex treatment methods specifically due to the presence of contaminants like dyes, solvents, and salts in textile wastewater (Garg & Joshi, 2015; Holkar et al, 2016; Srivastava et al, 2021; Zhang et al, 2021).…”

Water is crucial for enhancing the yield of agricultural land to meet the growing demand. Forward osmosis (FO) is a developing technology that utilizes the natural osmotic gradient of solutions. In this study, fertilizer drawn FO setup was considered by using potassium chloride (KCl) as the draw solution (DS) for treating textile wastewater as the feed solution (FS). This study investigated the effects of FS temperature, pH, and FS and DS concentrations. The performance investigation involved the study in terms of water flux, reverse salt flux, and specific reverse salt flux. DS and FS properties, osmotic potential, and temperature played a vital role in the performance. At 30°C FS temperature, the highest water flux (5.5 LMH) was observed. Reverse salt flux increased due to the increase in solute diffusivity. The highest value of water flux was obtained at a DS of 1.150 M and FS of 1000 mg/L. The permeation of water improved due to the difference in DS and FS concentrations at pH values above 7. The results of this study suggest that KCl as DS has a higher potential for the treatment of textile wastewater at a temperature of 30°C. Additionally, the functional groups attached to the FO membrane were identified through Fourier‐transform infrared (FTIR) spectroscopic study. Practitioner points Treatment of textile wastewater with the use of fertilizer draw solution (KCl) by forward osmosis process as carried out. The performance was assessed in terms of water flux, reverse salt flux, and specific reverse salt flux. The effects of feed and fertilizer draw solution concentrations; pH and temperature were evaluated on the performance of FO process.

“…These substances are often of synthetic origin and have a complex aromatic molecular structure, which increases their chemical and microbiological stability, hence their difficult removal from water. The introduction of dyes into the water system causes a number of health and environmental problems: Dyes increases the water turbidity; Dyes have a major impact on the photosynthetic activity of the aquatic environment because they block the penetration of light into the water, thus inhibiting the growth of algae, which are not only important for oxygen production but are a pillar of the food chain; Most of the dyes are carcinogenic (bladder, kidney, liver), mutagenic and toxic to living organisms; They can cause allergic reactions: skin, eye, mucous membrane irritation, dermatitis, respiratory problems; and They cause harm to aquatic environment, and may be toxic to aquatic organisms due to their aromatic, heavy metal and chlorine content [ 3 , 11 , 12 ]. …”

Factors Affecting Synthetic Dye Adsorption; Desorption Studies: A Review of Results from the Last Five Years (2017–2021)

The primary, most obvious parameter indicating water quality is the color of the water. Not only can it be aesthetically disturbing, but it can also be an indicator of contamination. Clean, high-quality water is a valuable, essential asset. Of the available technologies for removing dyes, adsorption is the most used method due to its ease of use, cost-effectiveness, and high efficiency. The adsorption process is influenced by several parameters, which are the basis of all laboratories researching the optimum conditions. The main objective of this review is to provide up-to-date information on the most studied influencing factors. The effects of initial dye concentration, pH, adsorbent dosage, particle size and temperature are illustrated through examples from the last five years (2017–2021) of research. Moreover, general trends are drawn based on these findings. The removal time ranged from 5 min to 36 h (E = 100% was achieved within 5–60 min). In addition, nearly 80% efficiency can be achieved with just 0.05 g of adsorbent. It is important to reduce adsorbent particle size (with Φ decrease E = 8–99%). Among the dyes analyzed in this paper, Methylene Blue, Congo Red, Malachite Green, Crystal Violet were the most frequently studied. Our conclusions are based on previously published literature.

“…Their effluent contains such nonbiodegradable chemicals which are causing reducing in levels of chemical oxygen demand (COD), biological oxygen demand (BOD), optical density (OD), and suspended solids (SS) of the aqua ecosystem. When mixed with soil, the effluent is destroying the soil pH and bacterial activity of the soil, which in turn causing the destruction of agri-land (Jadhav and Jadhav 2021;Lellis et al 2019;Yaseen and Scholz 2019). A lot of money, labor, energy, and time are being spent to treat such effluent load, but day by day, the rapid industrialization to provide the charm of life is causing the global heat and spreading various hazardous diseases for the global community.…”

Sustainability in all applied fields particularly in textiles is to protect our globe, environment, and community, where green dyed products are playing their role. For the current study, Esfand (Peganum harmala) has been explored using a green isolation tool, i.e., ultrasonic (U.S.) rays, and applied onto fabric. Different dyeing parameters have been explored statistically through response surface methodology by employing temperature (50-80°C), time (25-65 min), extract volume (15-55 mL), salt (1-5 g/100 mL), and dye bath pH (4-7) through series of experiments. For developing new shades, green mordants such as elaichi, neem, turmeric, and zeera have been utilized. It has been found that exposure of 35 mL extract of 7 pH containing 3 g/100 mL of salt as exhausting agent to U.S. rays for 30 min for the dyeing of silk at 70°C for 45 min has given maximum color strength with reddish-yellow shades. Color characteristics obtained in the CIE Lab system reveal that 5% of turmeric as meta bio-mordant has given good quality reddish-yellow shades. It is found that U.S. rays have not only good potential to isolate colorant followed by dyeing of silk under reduced condition but also the application of bio-mordants have made the process more greener, sustainable, and cleaner.
