“…Thus, understanding the removal mechanisms of CECs via ozone‐BAF and its linkage to the design and operational variables are still evolving. Bulk organic parameters such as TOC or dissolved organic carbon (DOC) and ultraviolet absorbance (UVA) are oftentimes used as surrogate indicators to predict the fate and transport of trace organic compounds in ozone‐BAF systems (Arnold et al, 2018; Dickenson, Drewes, Sedlak, Wert, & Snyder, 2009; Gifford et al, 2018; Ibn Abdul Hamid, Sanciolo, Gray, Duke, & Muthukumaran, 2019; Im, Nakada, Fukuma, & Tanaka, 2019; G. Li, Ben, Ye, Zhang, & Qiang, 2018; Sundaram et al, 2020; Tackaert et al, 2019; Trussell et al, 2016). However, the complex matrices found in wastewaters with different degrees of susceptibility to oxidation and adsorption/biodegradation make it difficult for TOC or UVA alone to provide predictions of CEC removal.…”

Water quality, in combination with design and operational data collected from multiple studies, was assessed to benchmark the performance of ozone‐biologically active filtration in reuse applications. A total of 149 contaminants of emerging concern, representative of multiple categories and chemical structures, were prioritized and systematically compared to elucidate apparent differences in removal capabilities as affected by multiple factors such as influent water matrix, ozone‐to‐organic carbon ratio, empty bed contact time, filtration media type, and initial media condition. The results were consistent with earlier findings for the removal of highly amenable compounds but demonstrate inconsistencies and knowledge gaps across multiple facilities for the more persistent compounds. Analysis of this multistudy data‐mining effort also demonstrates a complicated interplay between contaminant removal and numerous design and operational variables. Hence, further systematic investigation is warranted to elucidate the underlying removal mechanisms.

Water is one of the main sources of life’s survival. It is mandatory to have good-quality water, especially for drinking. Many types of available filtration treatment can produce high-quality drinking water. As a result, it is intriguing to determine which treatment is the best. This paper provides a review of available filtration technology specifically for drinking water treatment, including both conventional and advanced treatments, while focusing on membrane filtration treatment. This review covers the concerns that usually exist in membrane filtration treatment, namely membrane fouling. Here, the parameters that influence fouling are identified. This paper also discusses the different ways to handle fouling, either based on prevention, prediction, or control automation. According to the findings, the most common treatment for fouling was prevention. However, this treatment required the use of chemical agents, which will eventually affect human health. The prediction process was usually used to circumvent the process of fouling development. Based on our reviews up to now, there are a limited number of researchers who study membrane fouling control based on automation. Frequently, the treatment method and control strategy are determined individually.

“…The effects of other upstream treatments such as coagulation, ozonation or chlorination on bacterial growth and density have to be considered, as these treatments can impact biofilm development. For example, residual chlorine in the influent water to a pilot-scale BAC unit reduced the bacterial attachment on its surface, while a pre-ozonation process before BAC treatment improved the biological activity of the biofilm for contaminant degradation in many cases 18,23,[106][107][108] . These aspects should be considered during design of BEB filters for industrial/ municipal applications.…”
