Catalytic Advanced Oxidation Processes for Sulfamethoxazole Degradation
Applied Sciences, 2019 The degradation of sulfamethoxazole (SMX) by several advanced oxidation processes (AOPs) is carried out in the presence of different catalysts. The catalysts used consisted of carbon nanotubes (CNT), titanium dioxide (TiO2), a composite of carbon ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study investigates binary zeotropic mixtures of R744 (CO₂) blended with eco‐friendly refrigerants for medium‐high temperature heat pumps, comparing them with conventional R744/R134a systems. All mixtures meet 60–80 K temperature lift requirements under low‐temperature conditions. A genetic algorithm optimized system parameters using fixed

Treatment and removal strategies for estrogens from wastewater [PDF]
, 2008 Natural and synthetic steroidal estrogens (estrone, 17β-estradiol and 17α-ethinylestradiol) are endocrine disrupters, that are discharged consistently from the sewage treatment works into surface waters, thereby causing endocrine disrupting effects to ...

Methane Generation Using an Anaerobic Biodigester From Waste Leachate Water
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Leachate wastewater (LWW) is characterized by slow biodegradation and low biogas production due to resistant materials and limited biological activity. Therefore, applying pretreatments is essential to improving biodegradation potential, which consequently boosts energy recovery.
