USBF Technology Summary
The upflow sludge blanket filtration process,
USBF™ is the result of over fifty years of
research, development, testing and practical
experience. It is a modification of the
conventional activated sludge process that
incorporates an anoxic selector zone and an
upflow sludge blanket filtration clarifier all in
one integrated bioreactor vessel.
The treatment includes not only the efficient
reduction of BOD5 and TSS but also biological
nutrient removal (BNR) by the processes of
denitrification and “biological luxury uptake”.
The ensuing compact, modular system takes up
significantly less space and contains very few
moving parts. The result is an efficient, highly
affordable wastewater treatment plant with low
maintenance and operating costs.
USBF technology has no inherent capacity limits
and is used in a wide range of applications.
Plants serving the domestic and municipal
sectors or treating industrial, food processing
and agricultural wastewater are in successful
operation worldwide.
Since the high treatment efficiency of the
advanced secondary USBF process opens the
door to cost effective tertiary post-treatment,
the process has also been increasingly utilized in
the design of water reclamation plants.
THREE FEATURES THAT INCREASE
EFFICIENCY AND REDUCE COSTS
USBF Clarifier
Upflow sludge blanket filtration in a prism or a
cone shaped clarifier introduces a substantially
higher specific rate of separation than other
commonly used separation techniques. Unlike
conventional clarifiers, the influent enters at the
bottom and flows upwards. As the cross
sectional area increases, the upflow velocity
decreases until the activated sludge flocs
become stationary and thus form a filtering
media for activated sludge flowing through. High
filtration efficiency is achieved and even
particles with settling velocities too low to be
removed by settling alone are filtered out.
High Sludge Concentration
Most traditional plants operate at low or
medium sludge concentrations, typically 2,500 –
3,500 mg/l. USBF clarifiers by contrast operate
at higher sludge concentrations, typically 4,000
– 6,000 mg/l resulting in longer sludge age and
increased biological efficiency.
All Processes Integrated into One
Reactor
Most conventional technologies carry out
processes of nitrification, denitrification,
clarification and sludge stabilization in a number
of dedicated vessels. By contrast, USBF
technology incorporates all of these processes
inside one compact bioreactor, reducing
equipment size and liquid handling
requirements.
PROCESS
Operation of a USBF plant is simple and selfregulating.
Wastewater enters the anoxic
compartment of the bioreactor where it mixes
with activated sludge recycled from the bottom
of the clarifier. Agitated and moved in a plug
flow manner, the mixed liquor flows into the
bioreactor’s aerobic compartment.
After aeration, a stream of the mixed liquor
enters the bottom of the clarifier where the
sludge flocs and water are separated by upflow
sludge blanket filtration. After separation,
filtered effluent overflows into a collection
trough and is discharged from the system.
To complete the internal circulation loop,
activated sludge collecting at the bottom of the
clarifier is recycled back into the bioreactor’s
anoxic compartment.
BENEFITS
High Treatment Efficiency Including
Biological Nutrient Removal (BNR)
The USBF process features an internal anoxic
compartment for biological reduction of
nitrogen and phosphorus by nitrification,
denitrification and 'luxury uptake' processes
respectively.
Alkalinity Recovery & Filamentous
Bacteria Control
The integral denitrification process facilitates
partial recovery of alkalinity during nitrification.
As well, the anoxic selector is used to control
filamentous bacteria growth within the system.
No Primary Clarification
USBF technology does not require primary
clarification prior to biological treatment. A
proper screening facility and for larger plants,
grit removal system is all that is required
upstream of the bioreactors.
Hydraulic Flexibility
The clarifier's prism or cone shape not only
allows other treatment processes to take place
around it, but it also facilitates superior
hydraulic flexibility. USBF technology easily
accommodates high peak flows and flow swings
in a self-regulating manner; the higher the flow,
the higher the sludge blanket rises and the
larger the filtration area becomes.
Modular and Flexible Design
Modularity of design allows owners to stage
plant development and balance early outset
capital expenditures more easily. The modular
nature of the system also ensures that plants
can be quickly expanded if and when growth
demands. A variety of construction materials
can be used and USBF clarifiers can be
retrofitted into virtually any existing tank or
packaged together as a completely selfcontained
unit.
Reduced Operating and Maintenance
Requirements
The compact design, minimal amount of moving
parts, modularity of construction and selfregulating
hydraulics result in reduced
supervision requirements, contributing to lower
operating and maintenance costs.
Reduced Site Requirements
USBF technology incorporates nitrification,
denitrification, clarification and sludge
stabilization all into one compact bioreactor
which reduces equipment size and liquid
handling requirements and ultimately leads to a
smaller plant footprint.
Virtually No Odor
Aerobic conditions throughout the bioreactor
and extended sludge age dramatically reduce
the potential for odor production. USBF plants
can be located within populated areas without
the concern of odor problems.
Improved Sludge Characteristics
Low microbial loading (extended sludge age of
25-35 days) produces less excess, aerobically
stabilized sludge and improves sludge structure
and mechanical dewatering characteristics.
Patented and Proven
With literally hundreds of plants in operation
worldwide, USBF technology has been proven
to consistently deliver high quality treated
effluent in a variety of applications.
APPLICATIONS
Municipal and Domestic Wastewater
Customized and packaged USBF treatment plants serving municipalities,
communities, subdivisions, ski resorts, shopping
centers, summer resorts, golf courses, hotels,
restaurants etc. are in operation worldwide.
Water Reclamation
High advanced secondary treatment efficiency of
the USBF process paves the way for efficient and
economical tertiary treatment. USBF is
increasingly, and with advantage, used in the
design of treatment plants producing unrestricted
access (Class A or Title 22) reclaimed water.
Existing Plant Retrofits
The self-contained nature of the internal
circulation loop and structural independence of
the USBF clarifier insert make it possible that
virtually any tank can be converted to a
wastewater treatment plant. Many existing RBC’s,
oxidation ditches and other plants have been
retrofitted with USBF clarifiers to increase
treatment efficiency and/or plant capacity.
Industrial Wastewater
Many plants treating high strength industrial
wastewater including food processing plants,
slaughterhouses and rendering plants, dairy plants
and pulp mills have been designed and are in
successful operation worldwide.

Truth
All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident. Arthur Schopenhauer 2/22/1788-9/21/1860

Excellence
Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit.
