Tube-in-tube membrane photoreactor as a new technology to boost sulfate radical advanced oxidation processes

Reduction of Ultrafiltration Membrane Fouling by the Pretreatment Removal of Emerging Pollutants: A Review

“…In addition, residual oxidants will accelerate membrane aging and cause irreversible material consumption [ 35 , 75 ]. Electrochemical catalysis or strong oxidant catalysis will inevitably bring about problems such as incomplete degradation and pollutant residues [ 15 , 39 , 81 ]. The transformation products show high toxicity potential and low biodegradability in their chemical structures and may be carcinogenic or mutagenic under specific circumstances [ 81 ].…”

“…Lumbaque et al proposed a design idea using an inner-tube photoreactor to improve the removal efficiency of peroxydisulfate (PDS) through photolysis and photocatalysis. Photolysis and photocatalysis pathways include the following: (1) PDS dissociates S 2 O 8 2− for direct oxidation; (2) PDS driven by UV to break the homologous O-O bond and generate SO 4 •− after activation; (3) UV-excited H 2 O/S 2 O 8 2− system to generate • OH/S 2 O 8 •− ; (4) UV light-driven activated O 2 /S 2 O 8 2− system reduced to O 2 •− /SO 4 •− [ 81 ]. The tubular ceramic UF membrane can be used as the carrier of the contact surface between the catalyst and the oxidant, effectively promoting PDS’ participation in the transport process of the catalytic surface and water inlet [ 81 ].…”

Characterization and efficiency of chitosan zinc-oxide nano-adsorbent coated sand filter bed for milk processing industry wastewater treatment

“…The invention of the best technology for wastewater treatment remains a challenge for many inventors, especially due to the adaptability, stability, and commercialization of novel technologies on a commercial scale (Pereira et al 2018). In the recent generation, many researchers have worked on various industrial wastewater treatment technologies such as aerobic sludge digestion (Wei et al 2021), sul dogenic oxicsettling anaerobic process (Huang et al 2021), X-ray media assisted advanced oxidation processes (Li et al 2020), microbubble ozonation coupled with the biological process (Deng et al 2021), electro-assisted catalytic oxidation (Sun et al 2019), photochemical oxidation using UV/H 2 O 2 , electro-chemical techniques (Lhotský et al 2017), coagulation or occulation (Yu et al 2020), coagulation or occulation (Yu et al 2020), ion exchange (Edgar and Boyer 2021), membrane technology (Lumbaque et al 2021), and biosorption (Kunoh et al 2017). However, these treatment methods have limited applications because they are ineffective in meeting practical utility, stability, scalability, and rationality, and they are too expensive to nd a wide application.…”

Adsorption modelling and fixed-bed column study on milk processing industry wastewater treatment using chitosan zinc-oxide nano-adsorbent coated sand bed

“…The invention of the best technology for wastewater treatment remains a challenge for many inventors, especially due to the adaptability, stability, and commercialisation of novel technologies on a commercial scale (Altiparmaki et al 2022). In recent generations, many researchers have worked on various industrial wastewater treatment technologies such as aerobic sludge digestion (Wei et al 2021), sulfidogenic oxic-settling anaerobic process (Huang et al 2021), X-ray media assisted advanced oxidation processes (Li et al 2020), microbubble ozonation coupled with the biological process (Deng et al 2021), electro-assisted catalytic oxidation (Sun et al 2019), photochemical oxidation using UV/H2O2, electrochemical techniques (Lhotský et al 2017), coagulation or flocculation (Yu et al 2020), ion exchange (Edgar and Boyer 2021), membrane technology (Lumbaque et al 2021) and biosorption (Kunoh et al 2017). However, these treatment methods have limited applications due to their commercial application, not being effective, practical utility, stability, scalability, and rationality.…”
