2. A similar but variant technology to UASB is the expanded granular sludge bed ( EGSB ) digester.
3. The EGSB design is appropriate for low strength soluble wastewaters ( less than 1 to 2 g soluble COD / l ) or for wastewaters that contain inert or poorly biodegradable suspended particles which should not be allowed to accumulate in the sludge bed.
4. Researchers suspect the toxin is coming from old electrical transformers, dumps that were not capped properly, sludge beds and disposal sites for PCB-laced sediment dredged from rivers and shipping canals, as well as a host of smaller sites, said Tom Holsen, an environmental engineering professor at Clarkson University in New York, who is leading the PCB study in Chicago.
