Abstract |
Laboratory analyses were conducted on plasticized PVC perforated membrane tube diffusers after varying periods in service at two different municipal wastewater treatment facilities. One set of diffusers from Cedar Creek, NY, was in service for 26 months. The other set from the Green Bay Metropolitan Sewerage District facility was in service for approximately 47 months. Tests on the membranes included dynamic wet pressure (DWP), flow uniformity, weight, dimensions, tensile modulus of elasticity, hardness, and standard oxygen transfer efficiency (SOTE). |
