July 2, 2021: 2 Power Lunch Hour Webinar Options (1 Hour for WW & 1 Hour for Water)
July 2, 2021 @ 12:00 pm - 1:00 pm
1.0 Wastewater Hour
The West Lafayette, Indiana WRRF conducted a pilot study of cloth media disk filtration for use as both primary treatment and for treatment of wet-weather flows. The purpose of the study was to assess the performance of cloth media filtration to demonstrate and achieve effluent quality to meet IDEM requirements for discharge of CSO flows utilizing auxiliary treatment at the WRRF. This study also demonstrated the capabilities to treat primary influent on a continuous basis providing advanced primary treatment. Observed pollutant removal rates will assist in the future design of a potential full-scale cloth media filtration facility.
This presentation will describe the cloth media filtration process and pilot equipment, review the results of the performance testing, and discuss potential applications and their benefits. The benefit of advanced primary treatment is energy savings within the treatment plant along with a very small footprint.
1.0 Water Hour
Advances in technology have enabled water utilities to make much progress in reducing their operational and maintenance expenditures. One area that has historically troubled many water utilities is the expense involved in the interruption of service for non-payment and the restoration of service once the account has made an appropriate restitution to the utility. The introduction of customer web portals and remote disconnect valves for residential and light commercial services, however, is helping many utilities reduce labor expenses.
The two water meter readers then spend a full day performing water service cutoffs. Shortly after water service is interrupted, the affected residents often make restitution to the utility, and the two water meter readers then work as quickly as possible—often at overtime pay rates—to restore water service. This labor-intensive process repeats itself every month.
