A Comprehensive Review on Various Phases of Wastewater Technologies: Trends and Future Perspectives

Eng—Advances in Engineering, Год журнала: 2024, Номер 5(4), С. 2633 - 2661

Опубликована: Окт. 15, 2024

Wastewater Treatment Plants (WWTPs) encompass a range of processes from preliminary to advanced stages. Conventional treatments are increasingly inadequate for handling emergent pollutants, particularly organic compounds with carcinogenic potential that pose risks aquifers. Recent advancements prioritize integrating Advanced Oxidation Processes (AOPs) and adsorbents conventional methods effectively retain pollutants enhance mineralization. There is growing preference non-chemical or minimally chemical approaches. Innovations such as combining ozone other biological photo-sono-assisted methods, alongside AOPs adsorbents, promising. These approaches leverage catalyst-assisted reactions optimize oxidation efficiency. This review aims provide holistic perspective on WWTP processes, spanning wastewater intake the production potable water, highlighting key technologies, operational challenges, future trends. The focus advancing sustainable practices enhancing treatment efficacy safeguard water quality address evolving environmental concerns effectively.

Ozonation for Low-Load Greywater Treatment: A Review and Experimental Considerations for Small-Scale Systems

Water, Год журнала: 2025, Номер 17(8), С. 1195 - 1195

Опубликована: Апрель 16, 2025

The effectiveness of ozone (O3) in eliminating various types microorganisms, as well oxidizing a wide range contaminants present wastewater, and drinking water, is extensively documented the literature, along with required concentrations, contact times (Ct values), reaction mechanisms for different pollutants, overall efficiency. This article presents comprehensive review on use aqueous O3 treatment disinfection, specifically low-contaminant domestic greywater (LGW), providing information its integration into design small-scale systems. Additionally, to complement theoretical findings, experimental tests were conducted using portable generator an operational facility treating (GW) from handwashing sinks. results confirmed that concentration increases over time but decreases volume water be treated increases. Water analysis showed significant reductions BOD5, turbidity, total suspended solids after treatment. Furthermore, demonstrated presence microorganisms LGW minimal, case fecal coliforms, ensuring 1 Log disinfection level this type system. O3, sole system, oxidation potential nearly twice chlorine, proved highly effective systems, promoting sustainable practices, resource conservation, environmental protection, public health.

Fracking wastewater treatment: Catalytic performance and life cycle environmental impacts of cerium-based mixed oxide catalysts for catalytic wet oxidation of organic compounds

The Science of The Total Environment, Год журнала: 2022, Номер 860, С. 160480 - 160480

Опубликована: Ноя. 24, 2022

Water scarcity and the consequent increase of freshwater prices are a cause for concern in regions where shale gas is being extracted via hydraulic fracturing. Wastewater treatment methods aimed at reuse/recycle fracking wastewater can help reduce water stress process. Accordingly, this study assessed catalytic performance life cycle environmental impacts cerium-based mixed oxide catalysts wet oxidation (CWO) organic contaminants, order to investigate their potential as treatment. For these purposes, MnCeOx CuCeOx were tested phenol removal presence concentrated NaCl (200 g L-1), which represented synthetic wastewater. Removal pure ("phenolic") without was also considered comparison. Complete (100 %) 94 % total carbon (TOC) achieved both phenolic wastewaters by utilising (5 L-1) insignificant metal leaching observed. However, much lower activity observed when same amount utilised: 23.3 20.5 TOC removals, respectively, phenolic, 69.1 63 Furthermore, severe copper from during stability tests conducted A assessment (LCA) carried out part work showed that production had 12-98 than due higher manganese precursors. CWO found be 94-99 those ozonation energy material requirements. Overall, results suggest adoption would improve efficiency sustainability process whole.
