Special Issue Information

Dear Colleagues,

The occurrence of enteric microbial pathogens and indicators, including bacteria, viruses, and protozoan parasites, in environmental water has been examined worldwide, and their removal or inactivation efficacy during water treatment processes has been investigated over the past several decades. A general strategy to resolve health-related concerns and issues pertaining to treated waters, such as drinking water and reclaimed wastewater, includes source control and application of advanced treatment processes. A great deal of attention has focused on the treatibility of commonly known pathogens and microbial indicators, and conventional treatment processes for both drinking water and wastewater have demonstrated efficiency in the removal and/or inactivation of a variety of microorganisms. However, research gaps for further studies still exist, particularily related to new treatment technologies and emerging pathogens. Reflecting the removal and inactivation efficacy of microorganisms in water, this Special Issue will welcome contributions in areas including, but not limited to: Microbial removal and disinfection in drinking water, wastewater, and reclaimed water; alternative treatment processes and current trends in advanced water treatment including advanced oxidation, UV-LEDs, Cu-Ag ionization, ferrate, etc.; water treatment processes used in centralized utilities, point-of-use devices and secondary water treatment for premise plumbing water systems; sustainable energy saving treatment and economical strategies specifically applicable in developing countries; and quantitative microbial risk assessment. This special issue can provide current state-of-the-art research on microbial treatment technologies, insights on clean and safe water production for public health, and future research directions on better treatability of waterborne pathogens.

Ultraviolet light-emitting diodes (UV-LEDs) have recently emerged as a viable technology for water disinfection. However, the performance of the technology in full-scale drinking-water treatment systems remains poorly characterised. Furthermore, current UV disinfection standards and protocols have been developed specifically for conventional mercury UV systems and so do not necessarily provide an accurate indication of UV-LED disinfection performance. Hence, this study aimed to test the hypothesis that a full-scale UV-LED reactor can match the Cryptosporidium inactivation efficiency of conventional mercury UV reactors. Male-specific bacteriophage (MS2) was used as the Cryptosporidium spp. surrogate microorganism. The time-based inactivation efficiency of the full-scale reactor was firstly compared to that of a bench-scale (batch-type) UV-LED reactor. This was then related to mercury UV reactors by comparing the fluence-based efficiency of the bench-scale reactor to the USEPA 90% prediction interval range of expected MS2 inactivation using mercury UV lamps. The results showed that the full-scale UV-LED reactor was at least as effective as conventional mercury UV reactors at the water-quality and drive-current conditions considered. Nevertheless, comparisons between the bench- and full-scale UV-LED reactors indicated that improvements in the hydraulic flow profile and power output of the full-scale reactor could help to further improve the efficiency of UV-LED reactors for municipal drinking water disinfection. This represents the world’s first full-scale UV-LED reactor that can be applied at municipal water treatment works for disinfection of pathogenic microorganisms from drinking water. Full article
