Abstract:
Billions of people worldwide suffer from poor sanitation due to a lack of wastewater infrastructure.  With high CAPEX and OPEX, the conventional approach of centralized wastewater treatment plants served by an extensive sewer system is not an option for many communities. A new classification of modular and pre-fabricated non-sewered sanitation systems (NSSS, ISO 30500) has been introduced as an onsite micro-infrastructure alternative. Developed at the University of South Florida, the NEWgenerator is a solar-powered, modular, automated wastewater treatment and recycling system capable of operating independently from grid power, piped water and sewer.  The core technology within the NEWgenerator is the anaerobic membrane bioreactor (AnMBR), capable of handling a wide range of wastewater strengths, intermittent flows, and prolonged shutdowns. The value proposition of the NEWgenerator is that it makes flush toilets possible in off-grid, remote locations. The NEWgenerator was a recipient of the 5th Cade Museum Prize for Innovation and the 2020 USPTO Patents for Humanity Award. This presentation will follow the two-decade journey of the NEWgenerator from concept to development to commercialization, including extended field trials in India (Kerala) and South Africa (KwaZulu-Natal). The presentation will also highlight initiatives to implement the NEWgenerator in disadvantaged communities in the U.S.

Nutrient pollution (eutrophication) causes many water quality problems in freshwater and marine systems including harmful algal blooms, taste and odor issues, and hypoxia. Battles and skirmishes have occurred between the public, the regulated community and environmental scientists, as well as among scientists regarding causes and solutions for eutrophication. The initial battles to regulate nutrients were met with resistance from the public, but science prevailed in some cases (such as Lake Washington) to reverse eutrophication. These initial victories led many to the view that phosphorus control alone would stop eutrophication. However, many researchers have argued that nitrogen and other nutrients can play a role, and empirical data supports this view. Understanding the best attainable condition is important in setting management goals, and much progress has been made in doing so in the developed world, and more recently in developing countries. Still, controversies occur when scientists can benefit from supporting an anti-regulation viewpoint. This example demonstrates that translating science to protective action requires understanding basic aspects of human nature.
