• lower capital costs

• reduced energy consumption

• better peaking capacity

• less stringent screening requirements

• reduced footprint

With IMFAS

technology, both

energy usage and

membrane area

are significantly

reduced

compared to a

conventional MBR.

IMFAS is a sustainable

and cost-effective

path to membrane

quality effluent.

ENTEX has combined membrane separation

and integrated fixed-film activated sludge processes to

• minimize membrane area

• greatly reduce overall energy consumption

• further reduce the system footprint, and

• reduce overall installed cost.

Now you can get ultrafiltration membrane quality effluent at a cost competitive with

conventional activated sludge/tertiary filtration. With ENTEX proven attached growth

media in the bioreactor and an internal clarifier, high biomass is maintained in the reactor,

without subjecting the external membranes to a high solids working environment.

The IMFAS Advantage

IMFAS by ENTEX Technologies, continued

Advanced Systems. Proven Solutions.

The future is IMFAS

IMFAS means

• lower cost

• smaller footprint

• higher efficiency

• less energy

How does

IMFAS meet

the challenge?

The low fouling

nature of IMFAS

generated

suspended particles

allows the trans-

membrane pressure

drop to remain

consistently low,

even when

challenged with

high peak flow

periods and varying

influent turbidities.

• substantially less membrane area

• 50% lower energy cost

– no air scour blower

– no membrane clearing recycle pumps

– reduced aeration blower energy

• easy to operate & maintain

• no hollow fibers to break or plug

• no oversized EQ basins

• no ultrafine screening

(6 mm for IMFAS

vs. 1 mm for MBR)

A highly e�cient IFAS-membrane hybrid process, IMFAS dramatically lowers the membrane fouling rate and reduces energy consumption with minimum membrane surface area.

IMFAS �xes a majority of the biomass in the aeration basin. �e remaining suspended biomass forms a larger, stronger �oc, preventing fouling and clogging of the pore structure of the membrane.
