Use of dyes as well colorants in industrial processes has extensively increased. Effluents from various industries such textile, paint, food, etc. are reported to have a diverse range colorants. The effluents these often released into natural water bodies, causing serious and environmental pollution, which humans other species constantly exposed. Continued changes climate also affected availability for people around the world. Thus, advanced treatments removal harmful contaminants municipal wastewater becoming increasingly important. Removal can be done variety ways, including physical, chemical, biological treatments. These technologies, however, differ terms efficiency, cost, effect. There many technological economic challenges treatment methods currently available. search most suitable strategy successful degradation or is an urgent requirement. Previously published research suggests that use enzymes dye more effective compared traditional techniques. Nanoparticles, with their exceptional physicochemical features, potential tackle problem purification less energy-intensive way. However, extensive standardization would necessity different nanoparticles. Therefore, intense nanoparticle-based technologies may provide much needed solution remediation wastewater.

A Comprehensive Review on the Sustainable Treatment of Textile Wastewater: Zero Liquid Discharge and Resource Recovery Perspectives

Sustainability, Год журнала: 2022, Номер 14(22), С. 15398 - 15398

Опубликована: Ноя. 19, 2022

Clothing, one of the basic needs, demands growth textile industries worldwide, resulting in higher consumption and pollution water. Consequently, it requires extensive treatment effluent for environmental protection as well reuse purposes. Primary treatment, secondary tertiary are three major phases wastewater treatment. Secondary under aerobic anaerobic circumstances is carried out to decrease BOD, COD, phenol, residual oil, color, whereas primary utilized remove suspended particles, grease, gritty materials. However, biological not fully capable treating water according discharge/reuse standards. Hence, used final contaminants from wastewater. Adsorption regarded most feasible processes dye metal removal consideration cost variation adsorbent. Though membrane filtration an efficient process, operation limits its application. It’s unfortunate that there isn’t a universally applicable solution effluents. Therefore, only flexible strategy combine several therapy modalities. Treatment complicated, high-strength depending on pollutant load will be more successful if physical, chemical, approaches tandem. Enforcement stringent regulation policies, increasing costs demand freshwater, rising difficulties associated with disposal accelerating efforts toward achieving ZLD. Additionally, research into methods extracting useful materials has blossomed recent years. As such, purpose this analysis give holistic overview systems, focus zero liquid discharge (ZLD) resource recovery, both which may hasten transition sustainable management.

The review aimed to identify differences and similarities in the adsorption process of five azo dyes [congo red (CR), reactive black 5 (RB5), methyl orange (MO), II (OII), (MR)] on natural materials, biosorbents, industrial agricultural waste, or biomass, which are alternatives costly activated carbon locally available. were characterized compared based their molecular structure weight, water solubility, acid dissociation constant, n-octanol-water partition coefficient, maximum absorbance. RB5 CR diazo dyes, whereas MO, OII, MR mono-azo dyes. anionic is an dye, direct dye. CR, RB5, MR, OII molecules contain one more sulfonate functional group(s), but does not. We performed a literature following parameters: initial dye concentration, adsorbent dosage, pH, temperature, isotherm, kinetic models, thermodynamic parameters, synergetic competitive interactions. tended adsorb best acidic medium at higher temperatures. concentration dosage studies indicated importance using appropriate amount for effective removal. follow Langmuir isotherm pseudo-second-order model. Most processes endothermic spontaneous, leading increase randomness solid-liquid interface. These results indicate between Relevant mechanisms assumed be electrostatic forces, hydrogen bonding, π–π interactions, among others. Nevertheless, focus lies development characterization not study influences from matrix “industrial wastewater”. Therefore, research needed develop units application textile industries.

The Potential of Electrospun Membranes in the Treatment of Textile Wastewater: A Review

Polymers, Год журнала: 2024, Номер 16(6), С. 801 - 801

Опубликована: Март 13, 2024

Water security and industrial wastewater treatment are significant global concerns. One of the main issues with environmental contamination has been discharge dye from textile industries, contributing to an ever-growing problem water pollution, poisoning supplies, harming ecosystem. The traditional approach found be inefficient, biosorption techniques mechanisms have proven a successful replacement for conventional methods. Recent developments led recognition fibrous materials as environmentally friendly option broad application in several including treatment. This review explores potential produced by electrospinning technique adsorbents treatment, while at same time, removal adsorbates such oil, dyes, heavy metals, other substances, reported literature. Textile filtering structures, electrospinning, summarized use synthetic natural polymers this purpose is discussed. limitations electrospun structures also mentioned. Electrospun nanofibrous membranes appear very promising route filter therefore contribute reuse reducing courses.

The textile industry is one of the most chemical-intensive processes, resulting in unquestionable pollution more than a quarter planet's water bodies. high recalcitrant properties some these pollutants resulted on development treatment technologies looking at larger removal efficiencies, due to conventional systems are not able completely remove them their effluents. However, safeguarding environment also implies taking into account indirect from use chemicals and energy during treatment. On other hand, emerged need be economically attractive for investors managers. Therefore, costs should kept under control. For this reason, present study focuses comparative Life Cycle Assessment Costing four scale-up scenarios aiming mono di-azo reactive dyes wastewater. Two reactors (sequencing batch reactor two-phase partitioning) were compared different reaction environments (i.e., single anaerobic sequential anaerobic-aerobic) conditions (different pH, organic loading rates polymer).
