The fabric enterprise is recognized as a sector, which largest effect on the surroundings is related with principal water consumption and wastewater manufacturing Its water demand is estimated as 80–100 m3·Mg−1 of completed material. It is required to reap environmentally sustainable improvement in the material enterprise in view that closing of water cycle is notably recommended. The wastewater discharged with the aid of this enterprise is loaded with high quantities of each natural and inorganic compound. As an end result it has a very complicated composition. The effluents are characterised through alkaline reaction, tremendous salinity, intensive shade and toxicity. They contain: dyes, poisonous heavy metals, pentachlorophenol, chlorine bleaching, halogen carriers, carcinogenic amines, free formaldehyde, biocides, salts, surfactants, disinfectants, solvents, and softeners. A lot of beforehand referred to chemical compounds are xenobiotic substances. Among them dyes are determined as specifically essential. First of all, the quantity of accessible colourants exceeds 100,000. It is one of essential motives for severe variability of the fabric effluents. Secondly, they have to be resistant to picture and biodegradation, what makes their therapy very difficult. Usually, they pass by via traditional wastewater remedy plant life nearly unchanged. As a end result colored wastewater is emitted to the aquatic environment, the place creates hassle to photosynthetic aquatic flora and algae. Its composition is strictly linked to the manufacturing profiles, which rely on the market demand. Even inside one manufacturing facility massive differences can be discovered – for occasion associated to the season and trend tendencies. Due to the above noted facts, the material wastewater cure is fundamental however additionally an extraordinarily elaborate task. There are many strategies which can be used – biological, chemical and physicochemical. The most often, it is not possible to reap excellent consequences the usage of solely one of them – the integration of special methods is vital. Among the reachable methods ozonation and biodegradation sound as the most environmentally pleasant. The ozonation is acknowledged as procedure which generates no sludge. The residual ozone decomposes into water and oxygen. Additionally, ozone era is steeply-priced due to excessive strength consumption. This is why this approach has to be coupled with the others. Depending on the pH value, the ozonation technique follows two exceptional routes. Under acidic conditions, ozone reacts without delay with natural compounds as an electrophile. It assaults conjugated double bonds which are very frequently components of the chromophores in dyes. As a result, aldehydes, carboxylic acids and different by-products are fashioned. At simple pH, ozonation mechanism adjustments from direct ozonation to complicated chain mechanism. The ozone swiftly decomposes to produce the hydroxyl radical and different radical species. The hydroxyl radicals lead to quicker and in addition organics degradation than the ozone itself. For occasion they are capable to open fragrant rings of dyes. Apparently, the charge of dyes oxidation grows with growing answer pH [1-5].

Discussion

The study investigated the impact of two treatment methods, biodegradation and ozonation, on the toxicity of effluent from industrial textiles. Biodegradation involved the use of microbial organisms to break down organic compounds present in the effluent, while ozonation utilized ozone gas to oxidize pollutants. The results of the study revealed significant reductions in toxicity levels following both treatment methods. Firstly, the biodegradation process led to a notable decrease in toxicity, as evidenced by the reduction in the mortality rate of aquatic organisms exposed to the treated effluent. This suggests that the microbial activity effectively metabolized organic pollutants, resulting in a less toxic effluent. Additionally, the biodegradation process may have facilitated the degradation of complex organic molecules into simpler, less harmful compounds. Similarly, ozonation proved to be an effective method for reducing toxicity in the industrial textile effluent. The oxidative properties of ozone facilitated the breakdown of organic pollutants, leading to a decrease in toxicity levels. The generation of reactive oxygen species during ozonation likely contributed to the degradation of toxic compounds, resulting in a safer effluent. Comparing the two treatment methods, it was observed that ozonation generally resulted in a more rapid reduction in toxicity compared to biodegradation. This could be attributed to the faster reaction kinetics of ozone with organic pollutants, as well as the ability of ozonation to target a broader range of contaminants. However, biodegradation may offer long-term benefits in terms of sustainability and cost-effectiveness, as it relies on natural microbial processes. Furthermore, the study highlighted the importance of considering the potential formation of by-products during treatment processes. While both biodegradation and ozonation effectively reduced toxicity, there is a need to assess the formation of secondary pollutants to ensure the overall environmental safety of the treated effluent [6-10].

Conclusion

In conclusion, the findings of this study demonstrate the effectiveness of both biodegradation and ozonation in reducing the toxicity of effluent from industrial textiles. These treatment methods offer viable solutions for mitigating the environmental impact of textile manufacturing activities. While ozonation may offer faster results, biodegradation presents a sustainable and potentially cost-effective approach in the long term. Further research is warranted to optimize treatment conditions and assess the formation of by-products to ensure the overall environmental safety of treated effluent. Overall, the study underscores the importance of implementing effective wastewater treatment strategies to protect aquatic ecosystems and human health.
