It’s not unusual for this coastal resort wastewater plant to experience fluctuations in flow. Their plant generally handled those changes in flow pretty well, but the 4th of July weekend always resulted in an effluent ammonia spike, as flows jumped from 150,000 to 400,000 GPD in a short timeframe. The nitrifying bacteria weren’t capable of responding to the change quickly enough.
This year they used a more proactive approach. They fed our SmartBOD carbon supplement during the 2 weeks leading up to the holiday, to help acclimate the biology to greater loading. Then, immediately before the peak flow, they started adding our Vitastim Nitrifiers, to help speed the rate of ammonia uptake. This combination allowed them to meet their permit numbers this year.
SmartBOD provides an advanced carbon source to promote flocculation, build a healthy and diverse biomass, and can promote ammonia and phosphorus removal. As a dry powder, SmartBOD is easy to use and can be added in by hand or in larger applications can be fed with a screw feeder or slaking system.
