When you need power and flexibility to protect vulnerable indoor spaces, the portable PuraShield Smart offers more power, custom filtration media, and flexibility. Its digital display gives you a real-time report on indoor air quality, temperature, and relative humidity.
Even when school is closed, air quality is important to maintaining a healthy indoor environment. Now that we are implementing reopening strategies, it’s imperative that we do all we can to protect students, teachers, and staff—and the families they will be going home to. While social distancing and face masks are still the most important protective measures against the spread of COVID-19 in schools, ventilation systems offer opportunities for prevention as well. The CDC and other advisory groups recommend that we “Improve central air filtration [...]
Selection of Kluyveromyces Strains for Direct Conversion of Concentrated Lactose-Rich Streams into Bioethanol Dairy industries have a high environmental impact, with very high energy and water consumption and polluting effluents. To increase the sustainability of these industries it is urgent to implement technologies for wastewater treatment allowing water recycling and energy savings. In this study, dairy wastewater was processed by ultrafiltration and nanofiltration or ultrafiltration and reverse osmosis (UF/RO) and retentates from the second membrane separation processes were assessed for bioenergy production. Lactose-fermenting yeasts were tested in direct [...]
