Depth Filtration vs. Surface Filtration in Food, Beverage and Pharmaceuticals

2023-01-09T23:48:17+00:00January 9th, 2023|Filters|

In the manufacture of beverages, food and pharmaceuticals, depth and surface filters are commonly used. Depth filtration forces liquids through a random pattern of channels in filter media in order to trap particles. Depth filtration often functions as rough or primary filtration, because it removes larger particles before they reach finer pleated and membrane filters, extending the life and freshness of “downstream” filtration surfaces. Surface filtration uses a thin porous material to capture particles, allowing clarified liquid to flow through. Bag filters are examples. Depth Filters for [...]

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 [...]

Integrated Process for Bioenergy Production and Water Recycling in the Dairy Industry

2020-09-22T17:44:36+00:00November 9th, 2019|Filters|

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 [...]
