Energy Savings
Membrane bioreactor (MBR) technology
is recognized as the best available
technology for treating municipal and
industrial wastewater to alleviate water
scarcity, enable water reuse and help
protect our natural environment. With
over 25 years of MBR experience, GE
continues to set the standard for product
innovation, membrane manufacturing,
system design and customer support.
In addition to our industry-leading
ZeeWeed* MBR and LEAPmbr products,
GE brings innovation to other areas of an
MBR plant to enhance the performance
and efficiency of our customers’ facilities.
Our customers increasingly focus on
energy efficiency. Rising energy costs
and concerns about greenhouse gas
emissions mean that wastewater
treatment plant owners and operators
value equipment and processes that
reduce energy consumption.
LEAPprimary addresses the energy
challenge by significantly reducing the
energy required for secondary biological
treatment. The residual product
produced by the LEAPprimary system
enables energy recovery as it is rich in
organics and can be used in anaerobic
digestion, incineration or other solids
treatment to enhance the conversion
of carbon to energy in wastewater.
The combination of LEAPprimary with
LEAPmbr is the latest innovation in MBR
technology and makes achieving
exceptional effluent quality with low
energy consumption possible.
Addressing Our
Customers'
Challenges What is LEAPprimary?
LEAPprimary is an advanced primary treatment
system that combines separation, thickening and
dewatering of primary solids in a single compact
unit. The LEAPprimary system performs the same
function as a primary clarifier and fine screen
in a typical MBR plant. The figure below depicts
the performance advantages of combining
LEAPprimary and LEAPmbr technologies.
Reduced organic
load results in smaller
bioreactor and reduced
energy consumption
Enhanced influent

Removed solids can be
dewatered to 20% to 30%
dry matter to minimize
handling costs
High removal of TSS
(50% to 70%) and
BOD (25% to 40%)
reduces organic load
