ACS ES&T Engineering, Journal Year: 2021, Volume and Issue: 1(7), P. 1046 - 1064

Published: June 7, 2021

The emergence of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in the environment has created obstacles when treating infectious diseases with antibiotics. Wastewater treatment plants (WWTPs) serve as reservoirs for ARB ARGs can disseminate them into environment. It is important to understand address these risks. Generally, professional disinfection processes have been used WWTPs disinfect target water body, goal eliminating pathogenic microorganisms water. However, are not generally considered, spread developed through horizontal gene transfer (HGT). This Review provides a detailed overview application progress different traditional new technologies removing ARGs, mainly focusing on bacterial inactivation mechanisms chlorination, ozonation, ultraviolet (UV) (including UVA, UVB, UVC), sunlight, sunlight-dissolved organic matter (DOM), photocatalysis (PC)/photoelectrocatalysis (PEC). In addition, this also focuses technology involved clarifies underlying environments. Furthermore, by linking inactivation, describes how SOS response cell membrane permeability may be key step conjugation, transformation, transduction ARGs. Finally, given applications current problems associated light-based controlling challenges opportunities facilitate development future technologies. highlights research directions related ARG transmission control.

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

Sustainability, Journal Year: 2022, Volume and Issue: 14(22), P. 15398 - 15398

Published: Nov. 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.

For fifty years, heterogeneous photocatalysis has been considered as having potential to remove organic and microbiological pollutants from water under either artificial UV light or sunlight irradiation. However, after tens of thousands published research papers, this system unable move laboratory bench scale application mainly due intrinsic thermodynamic limitations well kinetical engineering drawbacks inherent the heterogenous nature process undergoing much longer treatment times when compared with other well-established options. Based on recent literature evidence, critical review aims describe discuss most significant TiO2-based photocatalytic processes eliminate biological chemical at a convenient degradation rate in noncomplex operational way. The properties mechanistic action mode TiO2 similar semiconductors their for are highlighted. Moreover, common strategies unsuccessfully explored overcome these described. Even if analysis is specially focused photocatalysis, assertions conclusions herein can be extrapolated all purpose reach disinfection detoxification. As 50 years ago, main challenge remains develop new, modified (i.e., doped), combined junctions) photocatalyst generating high oxidative species enough rates significantly decrease time type (hours) contrast seconds minutes observed systems.
