The next Central Section of the Professional Wastewater Operators Committee meeting will be held on Thursday, March 19, 2015, and hosted by the Mason Farm Wastewater Facility.

This is an open meeting, and you do not have to be a member to attend.  Everyone is welcome.  There will also be a gift card given to one lucky attendee, so don’t miss out.

The presentation will be at the plant in the conference room.  We will meet after the tour at The Tobacco Road Sports Café for lunch.  The address is 1118 Environ Way.  Those that wish to join us please RSVP to Melinda Ward so that we can plan the tables accordingly.

Technical Session
John Rutledge Jr. from Hach will be doing a presentation on Analytical Instrumentation for Process Monitoring & Control of WWTP’s.  This will focus on analytical instrumentation for wastewater treatment plants. He will be looking at the application of using Dissolved Oxygen & Ammonia probes for monitoring & controlling aeration basins.  Phosphorus Analyzer applications will also be discussed & their ability to monitor trends & control chemical feed for chemical phosphorus removal.  In addition to this, Total Suspended Solids, Nitrate & pH probes will be discussed.

Plant Tour
Mason Farm WWTP
170 Old Mason Farm Road
Chapel Hill, NC

The OWASA Mason Farm Waste Water Treatment Plant has a treatment capacity of 14.5 MGD with an average flow of ~8 MGD.  The plant uses preliminary and primary treatment for grease elimination and solids reduction.  The MFWWTP runs an advanced BNR activated sludge process with step feed and fermentation addition. As part of an effort to reduce energy costs and eliminate odor, within the last year, the activated sludge process has been upgraded to fine bubble diffusion and mechanical mixing. After the BNR process, the flow is sent to one of 5 secondary clarifiers and then sent to one of 6 deep bed tertiary denite filters. The treated effluent is disinfected using UV and reaerated before being sent to the Reclaimed Water Facility or the receiving waters of Morgan Creek.  The Reclaimed Water Facility (RCW) serves the University of North Carolina at Chapel Hill, and on average 0.7 MGD is sent to the University for irrigation and cooling tower make-up water.  For solids management, the Mason Farm WWTP has 4 anaerobic digesters, two of which are run in the thermophillic temperature range in order to meet the Class A biosolids requirement.  After digestion, the biosolids are either dewatered using a rotary press or land applied as a liquid.
