Summary: The blooming of the world's human population and the transition of the human diet into a more westernized, high-protein diet has accelerated the production of slaughterhouse wastewater (SWW) as the number of meat processing plants (MPP) has increased in the past few decades. Conventional treatment processes (CTP) used in treating SWW, such as anaerobic processes, membrane processes, and electrocoagulation, have significant limitations, such as low treatment efficiency, tendency to foul, and high energy consumption, respectively. While advanced oxidation processes (AOPs) appear promising in replacing the former, they lack economic feasibility when used as a single process. In this paper, the limitations and disadvantages of the CTPs used in treating SWW influents are evaluated. The idea of utilising AOPs as a complementary step rather than a single process is also discussed. The review paper further explores the variability of different AOPs, such as Fenton, Electro-Fenton, Sono-Fenton, etc., and their respective strengths and weaknesses in counteracting the limitations of CTPs. The idea of incorporating resource recovery into wastewater treatment is also discussed towards the end of the paper as a means of generating additional revenue for the industry players to compensate for the high operation and maintenance costs of SWW treatment. The integration of a new-generation treatment process such as AOP into CTP while being able to carry out resource recovery is a future hurdle that must be overcome by scientists in order to produce a versatile, powerful, sustainable, yet financially feasible and operationally pragmatic treatment system.

Summary: Pork production generates wastewater with high pollutant load and the intensive use of pharmaceuticals leads to effluents rich in these compounds. Traditional biological depuration treatments are effective on organic load removal but are time-consuming and inefficient on abating persistent contaminants like pharmaceutical compounds, necessitating the pursuit of alternative technologies.

Summary: This study developed a comprehensive assessment framework to compare an innovative algae resource recovery and reuse system with a conventional potable water reuse system. The study evaluated the costs of individual units and integrated processes and provided decision-makers with valuable information about cost optimization and improvements. The main system utilized algal-based wastewater treatment, forward osmosis membranes, and seawater reverse osmosis membranes, while the benchmark system used conventional treatment processes. The main system was estimated to have a lower water cost compared to the benchmark system, making it a more economically viable alternative.

Summary: In this study, different chemical species were used to treat poultry slaughterhouse wastewater under UV-C light. The combination of UV with 15mM of K2S2O8 resulted in the highest TOC removal efficiency and the lowest electric energy per order. The UV/K2S2O8 process could be used as a post-treatment after biological treatment to meet discharge water standards and reuse the wastewater.

Summary: This mini review discusses the current status and challenges of establishing institutional wastewater surveillance systems for COVID-19. While monitoring SARS-CoV-2 in wastewater is seen as a potential tool to understand the actual prevalence of COVID-19, challenges remain due to the evolving international understanding of the scientific knowledge and socio-political impacts of the virus. Comparing Japan, Viet Nam, and Indonesia in a study aims to identify common issues and country-specific problems to contribute to the development of a robust multistakeholder system for monitoring SARS-CoV-2 in wastewater as an effective disease surveillance system for COVID-19.

Summary: This study found that viral interference can affect the accuracy of detecting enteric viruses using ICC-PCR. Specifically, the presence of EV71 may inhibit the detection of AdV40, which can be neutralized by adding a growth inhibitor of EV71. Therefore, caution should be taken when using ICC-PCR to detect multiple enteric viruses in environmental water samples.

Summary: The study found that 24-hour composite samples offer increased analytical sensitivity and decreased variability compared to 1-hour composite samples when monitoring wastewater, especially for pathogenic viruses with low infection rates within a community. This suggests that 24-hour composite samples are less likely to produce false negative results and erroneous public health information in wastewater-based epidemiology applications.

Summary: Wastewater-based epidemiology (WBE) has the potential to predict COVID-19 cases. A highly sensitive method (EPISENS-M) was developed, allowing SARS-CoV-2 RNA detection from wastewater when new COVID-19 cases exceed a certain threshold. A longitudinal WBE study conducted in Sapporo City, Japan, showed a strong correlation between C-RNA and newly reported COVID-19 cases. A mathematical model was developed to estimate newly reported cases using C-RNA data and clinical data, with high precision in predicting future cases.

Summary: Wastewater-based epidemiology (WBE) is a promising approach for monitoring COVID-19, but the correlation between CRNA and clinically confirmed cases varies and the impacts of environmental and other factors are unclear. This study analyzed the correlation between CRNA and different types of clinically confirmed case numbers. It found a stronger correlation between CRNA and new cases, influenced by environmental and epidemiological conditions as well as sampling design.
