Water Treatment in
Power Generation
Facilities
• Significant volumes of water
are used in power plants for
cooling, scrubbing, or boiler
feed water purposes.
• Proper filtration must be
provided in order to treat the
waste effluent.

3.
SiC Membrane
Ultrafiltration
• Wtih water scarcity challenges
at an all time high -> long term
re-use of water is required
• H2O Systems SiC Membrane
Ultrafiltration has proven itself
in filtering waste effluent for
re-use in German & Danish
Powerplants

4.
How it works
Feed flow is tangential to the
surface of the membrane
in order to sweep rejected
particles and solutes away
CROSS FLOW FILTRATION

Scrubber
Effluent
Treatment
Scrubbing liquid from wet scrubbers in
coal fired power plants contain heavy
metals, ash, and soot.
Current Treatment systems rely heavily
on chemical dosing, handling, and
sludge disposal -> $$$ OPEX
• SiC Membranes have a smaller
footprint with 99% recovery rate->
reduced OPEX
• High flux & robustness can handle
highly fluctuating heavy metal
concentrations to meet regulatory
compliance in 1 step
• Can handle highly corrosive
scrubber liquid

7.
Cooling Tower
Filtration
Circulating process water is cooled
and re-used to extract heat in
condensers.
Variation in water quality, source,
and heat transfer surfaces
subject to corrosion, scaling, and
microbiological fouling
• SiC Membranes can be used
for sidestream ultrafiltration
to continuously filter TSS and
Mircobioligical organisms
• Ideal in scenarios with high bio-
fouling potential -> can be cleaed
with any chemical or strong oxidizer

8.
Boiler Feed
Water Treatment
Feed water of high purity is required to
ensure proper heat transfer in a steam
generation facility.
Reduction of impurities entering the
boiler system reduces scale buildup on
heat transfer surfaces which would also
reduce fouling.
• RO system is used to treat feed water
-> SiC Membrane Ultrafiltration used as
pre-treatment before RO system
• Filters TSS and TOC to reduce
subsequent RO membrane fouling
• Can be accomplished in a single
step without any added chemicals,
reducing the OPEX over its lifespan

9.
Boiler
Blowdown
Treatment
Blowdown water has TDS & heavy metals
that need to be filtered out and treated
for re-use
• SiC Membrane UF can handle varied
feed conditions with upsets in TDS/TSS in
feed water
• Can retain fine particulate and
heavy metals at high flux conditions
• Effective pre-treatment + RO solution
to conventional treatment options ->
reduced chemical reagents, process
steps, and OPEX
