COVID-19 and Recycled Wastewater Irrigation: A Review of Implications

This (non-peer reviewed) preprint is a collaborative study between researchers in Australia and Bangladesh. It considered the use of reclaimed wastewater for irrigation. While this is a very different application to the use of purified recycled water for supplementing drinking water supplies, the authors appear to have drawn very different conclusions to those described inContinue reading “COVID-19 and Recycled Wastewater Irrigation: A Review of Implications”

Presence and vitality of SARS-CoV-2 virus in wastewaters and rivers

There have now been many studies describing how the RNA of SARS-CoV-2 can be detected in wastewaters (sewage) and even in some environmental samples. Most of these have been the subject of some discussion on this blog. However, to understand public health implications, it is also necessary to understand whether any of that RNA isContinue reading “Presence and vitality of SARS-CoV-2 virus in wastewaters and rivers”

What are the implications of COVID-19 for purified recycled water?

Australian Water Association (AWA) Webinar: The impact of the virus that causes COVID-19, known as SARS-CoV-2, cannot be overstated. Almost every aspect of our lives has been affected in some way. When thinking about potable reuse, exposure and transmission of SARS-CoV-2 can be expected to be prominent among community concerns. These concerns will likely be heightenedContinue reading “What are the implications of COVID-19 for purified recycled water?”

Chemicals and microbes in bioaerosols from reaction tanks of six wastewater treatment plants: survival factors, generation sources, and mechanisms

Wastewater treatment commonly includes the production of air bubbles (aeration) at the bottom of activated sludge or during Dissolved Air Flocculation and Floatation. When the bubbles rise to the surface they burst, form droplets and ‘aerosolise’. This is how pathogenic microorganisms in the wastewater can become ‘airborne’.  The Experiment: Bioaerosol samples were collected from 0.1,Continue reading “Chemicals and microbes in bioaerosols from reaction tanks of six wastewater treatment plants: survival factors, generation sources, and mechanisms”
