Why Bigger Bubbles are Better
Larger bubbles
delivered at
shorter intervals
create more shear
and reduce fouling.
The effectiveness
of the large
bubbles results in
less total air
volume being
required.

Conclusions
Historical demonstration of low p consent limits
being achieved. Enables water companies to
be confident of hitting WFD discharge
standards.
LEAP MBR reduction of capital costs has
increased size of plants installed.
Significantly reduced operational costs notably
power.
