Innovative Low Energy Advanced Primary Treatment for MBR

Addressing Our
Customers'
Challenges

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.

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.

Compact design
reduces plant
footprint and
capital cost

High removal of TSS
(50% to 70%) and
BOD (25% to 40%)
reduces organic load
to biological treatment

Energy Savings

Reduce energy for

biological treatment by

25% and enable energy

recovery.

Cost Savings

Reduce primary treatment

equipment for your MBR

and save 20% to 40%.

Simplified Design

Combine primary solids

separation, sludge

thickening and dewatering

in one compact step.

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
exceptional effluent quality with
energy consumption possible.
