Nutrient Removing Filtration System (NRFS) O&M Manual
GENERAL INFORMATION
The Nutrient Removing Filtration System (NRFS) is a denitrifying
media treatment vault that is commonly used at the end of a
detention pond or for off line pretreatment applications. The NRFS
is an orice driven treatment vault for the removal of phosphorus,
nitrogen and total suspended solids. Bold & Gold Biosorption
Activated Media (BAM) is the exclusive media of choice in the
NRFS vault system.
The NRFS is highly effective in capturing Nitrogen, Phosphorus,
Total Suspended Solids, organics, trash, oils and grease. Independent
testing has shown the NRFS is capable of capturing up to 75% of
Nitrogen, 95% of Total Suspended Solids and 95% of Phosphorus.
Local and State regulations may require inspections and cleanings
every 90 days. Oldcastle Infrastructure recommends inspections be
conducted quarterly for optimal removal efciency.
Benets
• Low maintenance (media does not require removal for servicing)
• Easily retrofits existing watersheds
• No organics to degrade and lose treatment capability
• Servicing is accomplished quickly using a vacuum truck
• Removes phosphorus, nitrogen and TSS
• Uses genuine Bold & Gold Biosorption Activated Media

INSPECTION INFORMATION
05
Oldcastle Infrastructure recommends the following
inspection guidelines:
The Bold & Gold media is positioned vertically between two layers of
river rock. The layer of rock below the Bold & Gold should be 6”-10”
thick and the layer above should be 6” thick. The Bold & Gold layer
itself should be 30” thick and is possible to never need servicing. To
determine if the media bed requires servicing, visually inspect the top
layer of the media bed for any type of debris. It is safe to assume that
the top layer of the media bed is the only place that would accumulate
any debris. The decision to service the NRFS is based on the amount
of debris accumulated on top of the media bed and if it is negatively
impacting treatment ow rates. All inspections must be documented
using the included inspection checklist.
• Visually inspect the vault from the surface for broken or missing
hinges / handles.
• Open all access points (Manholes / Hatches) and secure each of
them properly.
• Visually inspect the sediment chamber to determine the
approximate accumulated sedimentation capacity.
• Inspect the conditions of all joints and the inflow / outflow pipe
grout areas for cracks and wear.

OPERATION INFORMATION
07
The Nutrient Removing Filtration System utilizes Bold & Gold
biosorption activated media without the need for cartridge lters
affording a more cost effective and efcient solution. Furthermore,
the use of Bold & Gold media can accommodate high ow rates
without organics which degrade and lose effectiveness over time.
• Stormwater enters the NRFS and flows upwards through the
Bold & Gold Media.
• Vault specifications allow for 24 hour detention for maximum
efficiency and media contact.
• During high or extreme flows the NRFS resists clogging.
(If the SkimBoss floating skimmer is equipped, it will rise
to allow water to bypass media filtration)
• Up to 75% reduction of total nitrogen and 95% total
phosphorus based on treatment area / site conditions.

REQUIREMENTS & PARTS
Minimum Equipment Requirements
The use of a vacuum truck is required for servicing of the Nutrient
Removing Filtration System. Service crews are recommended to
check all local, state and federal guidelines for servicing and
disposal of any collected debris and sediments.
Structural Components
The structural components of the NRFS are designed to have a life
span of several decades. Structural inspections are not required
unless stipulated in guidelines set by the local municipality, state
or federal agencies
Replacement Parts
All interior components are designed and sized to be assembled and
removed from the NRFS for servicing or for parts replacement. This
can easily be accomplished via the access ports atop the structure.
For any replacement parts or further instructions please contact

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 ushed and reused during servicing without removal.
Furthermore, the vacuum system eliminates the need for
conned space entry.
Vacuum Servicing
• Remove the manhole covers or open hatches.
• Lower the vacuum truck hose into the vault closest to the inow 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
ushed toward the vacuum line and removed.
• Remove vacuum line and disconnect truck water supply hose.
• Replace manhole covers or close top hatches.

BOLD&GOLD INFORMATION
Bold & Gold is a Biosorption Activated Media used for pollution
control to reduce nitrogen, phosphorus, TSS and turbidity levels in
stormwater. High phosphorus and nitrogen levels have the potential
to compromise human health as well as ecosystem integrity. Bold &
Gold media is ideal for pretreatment prior to rainwater harvesting or
following detention prior to discharge into receiving bodies of water.
Oldcastle Infrastructure is the only company in the USA licensed to
include Bold & Gold inside of a treatment vault system. Further
benets of using Bold and Gold Media include:
• Available in various sizes and blends for specic applications
• Economical and lower cost than other media
• Made from recycled materials
• Effectively removes up to 95% Total Phosphorus,
75% Total Nitrogen and 95% Total Suspended Solids
• Sustainable: No biological toxic effects
• High Surface Area
• Physical ltration for the removal of solids
• Sorbent surface bonding for the capture of dissolved pollutants
• Biological activity including nutrient based consumption
and denitrication

BOLD & GOLD REPLACEMENT
11
Media Replacement Procedure (If Necessary)
It is estimated that the physical ltration and biological activity
of Bold & Gold may last indenitely. However, the sorbent surface
bonding may diminish after a period of 15 years and therefore may
require replacement. It is important to determine a baseline removal
efciency of the unit when the system is rst installed. If it is
determined that the Bold & Gold is to be replaced, proceed
with the following steps for replacement:
1 Determine the appropriate amount of Bold & Gold needed for
replacement by rst contacting Oldcastle Infrastructure or your
local distributer. Stone can be purchased from local distributors.
2 Open all access points.
3 Using a vacuum truck, suction out all media and stone from the media
bed. When the vacuum line reaches the lower layer of stone be careful
to not move or dismount the underdrain. The underdrain pipes will not
be glued into the pipe ttings and can be disassembled to more easily
remove the stone and debris underneath the pipes.
4 Reassemble the underdrain pipe system.
5 Install the new stone around the underdrain pipes to a depth of 10”.
Be careful when placing the stone over the underdrain pipes to avoid
any damage.
6 Install the new Bold & Gold to form a layer 30” thick.
7 Install the top layer of stone to form a 6” thick layer.
8 Close all access points.

SKIMBOSS MAX INFORMATION
12
General Information
The included SkimBoss® MAX Skimmer prevents oating solids
and liquids from passing through the vault. Through the use of
Hydro-Variant Technology®, the SkimBoss MAX Skimmer can
automatically adjust to accommodate variations in water level
and ow with a negligible head loss.
• The SkimBoss MAX skimmer adjusts the hydraulic grade line via
Hydro-Variant Technology during high ows.
• Primary buoyancy is on the front inow side of the SkimBoss
to match rising water levels regardless of outow side levels.
• Once the hydraulic grade of the water reaches a point that is
20” above the bottom of the skimmer, the entire skimmer begins
to oat.
• During especially high ows in the NRFS, the SkimBoss will
rise and allow the water to bypass media ltration as to prevent
ooding concerns.
