ok
membrane bioreactor or MBR he's an
efficient and cost effective product for
treating municipal and industrial
wastewater the system can produce a
high-quality effluent that meets
stringent discharge standards and is
suitable for rias membrane bioreactors
can be customized and built to fit just
about any site this can require
additional engineering and may add lead
time for delivery and start up the
package membrane bioreactor from coke
membrane systems offers a convenient
alternative to a customized MBR design a
package system consists of
pre-engineered assemblies can be
rearranged in a variety of
configurations to accommodate the
restrictions imposed by floor space
limitations a typical package system
consists of an anoxic tank and aeration
tanks for biological treatment and
influence green a membrane module tank
assembly of filtration and chemical
cleaning equipment assembly and an air
blower assembly most of these units are
pre plumbed and pre-wired at the factory
to reduce installation time and cost the
installer simply connects the
preassembled units in the field the
compact design of the package system has
a small footprint the building block
approach allows the equipment layout to
be configured to fit buildings of
various sizes and shapes the system can
be easily expanded by adding
prefabricated assembly units to the
existing treatment operation with
minimal interruption the first step of
the treatment process is the mechanical
screening of the incoming wastewater the
waste water enters the screen that is
equipped with a two to three millimeter
perforated plate the solid particles are
screenings are retained and continuously
removed from the screen unit for
disposal the screen wastewater flows
into the anoxic tank
within the anoxic tank a submersible
mixer blends the screen wastewater with
the mixed liquor returning from the
membrane filtration tanks at
predetermined recycle rates to achieve
the desired level of denitrification and
the absence of dissolved oxygen nitrate
is converted to nitrogen gas in the tank
the wastewater flows from the anoxic
tank to the aeration tank
oxygen is supplied using air blowers and
a diffused aeration system
dissolved oxygen sensor monitors the
selected range to help the operator
maintain nitrification in the removal of
organic material in this oxygen-rich
environment organic material and ammonia
nitrogen are biologically oxidized to
carbon dioxide nitrate and water a pH
sensor is provided in the aeration tank
for continuous monitoring of the ph
condition from the aerobic tank mix
liquor is pumped to the membrane
filtration tank for liquid solid
separation pure on membrane modules are
fully submerged in the mixed liquor
inside the membrane tank for direct
outside to inside filtration the
membrane modules are made up of hollow
fibers with a nominal pore size of . 05
micron these robust reinforced
second-generation hollow fibers are cast
on an internal reinforcing braid to
overcome the fiber breakage problems
typical of first generation systems the
free-floating tips of the hollow fibers
in the single header design of the pure
on module also reduce breakage by
placing less mechanical stress on the
fibers than in modules that use a
doubleheader design
the membrane system is equipped with
rotary lobe pumps that creates suction
inside the hollow fibers and draw water
through the fiber wall to the permeate
collection tank
a programmable logic controller plc
automatically controls the filtration
membrane cleaning operations while
human-machine interface continuously
monitors the system performance the PLC
is ethernet capable to interact with
other plant PLC's or skater systems the
rotary lobe pumps periodically reverse
the flow at predetermined frequencies
and durations to back flush the membrane
fibers pneumatic valves as well as
pressure and flow measuring instruments
provide continuous monitoring and
control of system operation when
cleaning is required to restore the
desired flux the training membrane
modules is isolated from normal
operation and sodium hypochlorite and
citric acid are sequentially injected
into the membrane modules for Institute
chemical cleaning
excess biomass or sludge generated from
the biological treatment process will be
wasted on a periodic basis to maintain
the desired solids concentration within
the system sludge is withdrawn from the
bioreactor tanks or membrane tank for
proper offside disposal by licensed
haulers
permeate generated from the membrane
filtration process is transferred to a
permeate collection tank the
high-quality permeate will meet strict
local and EPA effluent discharge
criteria in many locations the permeate
is used for cooling tower water makeup
irrigation and toilet flushing in
summary the pure on MBR package system
offers the following benefits flexible
layout configuration factory assembled
package easily installed with minimal
site preparation low operating and
maintenance costs fully automated with
remote data access
