Special Issue Information
Dear Colleagues,
Disinfection of wastewater is often done in order to get irrigation water or to protect receiving surface waters used for fish production, recreational purposes, raw water of drinking water, industrial waters, etc. The needs for disinfection are increasing due to climate change, and its effects on precipitation and evaporation. In addition, the amount of wastewater will be increasing with urbanization and a higher coverage of sanitation. Normal wastewater treatment processes performed in municipal wastewater treatment plants or small-scale treatment units (different small-scale plants, sand filters, wastewater treatment ponds, etc.) do not usually efficiently reduce the number of enteric microorganisms.
In some cases, environmental regulations can control the number of Escherichia coli or other enteric microorganisms in effluent, so that wastewater treatment disinfection must be improved, and disinfection will be necessary (though not always). In these cases, should there be regulations for the numbers of enteric microorganisms in effluents?
There are new disinfection chemicals, which often have better efficiency relative to old ones, but their limitations must be considered. Different technological pre-treatments can be beneficial, as well as different combined treatments. The new disinfection chemicals may change the chemical quality of effluent. Original research articles dealing with these themes are welcome to this Special Issue of Water.
