USBF™ - Upflow Sludge Blanket Filtration

USBF™ is a patented technology recognized by many industry experts as the best biological wastewater treatment technology. In 2006, Frost & Sullivan rated it as a leading technology and in 2002, the University of California, Davis gave it the highest ranking of biological processes out of the almost 70 systems it studied. More recently, in 2010, researchers at the University of Tehran put the USBF™ under intense testing and reached the same conclusion about its excellence.

● Can treat any source of wastewater including municipal, agricultural and industrial;
● Can be designed for BOD (and/or COD) removal, as well as nitrification, denitrification and phosphorus removal;
● Can be customized to meet specifics of the influent and/or effluent parameters;
● Adaptable capacity ranges from 300 – 150,000 tonnes;
● Modular system permits decentralization and expandability;
● The process is a modification of the conventional activated sludge process;
● The process is simple, biological and environmentally-friendly;
● Energy-consumption and maintenance needs are minimal – few moving parts;
● The operations require only nominal monitoring and staffing;
● Low overall operating costs – energy, staffing and maintenance.

The USBF™ system is currently utilized in over 156 wastewater treatment plants in North America, Central America and the Caribbean. These have been installed, and in some cases, operated by ECOfluid Systems, Inc. , the company that developed the patent and trademark.
In May 2011, Alpha Wastewater purchased from ECOfluid Systems, Inc. the USBF™ technology, its patents, trademark as well as any existing and future advancements. We continue to have a close working relationship, whereby Alpha employs ECOfluid’s engineering and technical expertise to assist in the design of its plants and has granted ECOfluid an exclusive Technology Transfer License to use the USBF™ technology in North America, Central America and the Caribbean.
