Nutrient Removing Filtration System (NRFS) O&M Manual
NRFS MAINTENANCE
Summary
The Nutrient Removing Filtration System is easily serviced with the
use of a vacuum truck combined with the equipped HydroSlide®
service system. The HydroSlide system allows the media to be
back flushed and reused during servicing without removal.
Furthermore, the vacuum system eliminates the need for
confined space entry.
Vacuum Servicing
• Remove the manhole covers or open hatches.
• Lower the vacuum truck hose into the vault closest to the inflow pipe.
• Attach the vacuum truck water supply hose to the HydroSlide
service system quick connector.
• Start the HydroSlide service system using the vacuum truck hose
while operating the vacuum line. Debris will be quickly and easily
flushed toward the vacuum line and removed.
• Remove vacuum line and disconnect truck water supply hose.
• Replace manhole covers or close top hatches.
