Cleaning
Centrate Tank
Reused existing Aeration Basin
– Capital saving of $1,000,000
– Reduced bottleneck
– Reduce struvite build up
Cleaning made easy
New Dewatering Facility
Capital savings of $1,200,000
– Modified existing centrifuges Capital savings of $170,000
– Modified existing polymer system Capital savings of $400,000 utilizing PC pumps O & M costs have been reduced by $75,000
annually. (More to Come)
– Maintenance has been reduced 5 fold
– Lower polymer consumption
– Tempered polymer water-2% solids increase
New Dewatering Facility
Reduced dewatering shift from 16.5 hours to 9.5 hours
Truck load out from 16 hours to 15 minutes Truck loaded to specification each time Target and maintain consistent solids output Automation from 2 operators at a 16 hour shift, to 1
at 9.5 hours Sludge storage capacity Facility provides for very clean operation
