MEE
Multiple
Effect
Evaporator
for
Effluent
Treatment
Hanpu’s
Multiple
Effect
Evaporator
(MEE)
provides
a
proven,
energy-saving
solution
for
concentrating
industrial
effluents
and
reducing
disposal
volumes.
By
cascading
effects
under
vacuum,
the
system
reuses
latent
heat,
cuts
steam
demand,
and
delivers
stable
performance
across
challenging
wastewater
streams
from
chemicals,
pharma,
textiles,
food
&
beverage,
pulp
&
paper,
and
more.
Lower
Utility
Cost
Multi-effect
heat
reuse
and
optional
TVR/MVR
integration
improve
steam
economy
and
reduce
cooling
water
load.
High
Availability
Robust
falling-film
configuration,
anti-scaling
design,
and
online
cleaning
strategies
extend
continuous
run
time.
Quality
&
Compliance
ISO-aligned
fabrication,
SS304/SS316L
contact,
pressure
vessel
codes,
and
full
instrumentation
for
traceable
operation.
Smart
Control
PLC/HMI
with
flow,
temperature,
pressure,
level,
and
conductivity
control;
historian
for
OPEX
tracking.
How
It
Works
—
Falling-Film
Multi-Effect
Under
Vacuum
-
Feed
&
Preheat:
Effluent
is
metered
and
preheated
using
clean
condensate
to
save
live
steam.
-
Effect
1
→
Effect
2
→
Effect
3:
Live
steam
heats
the
1st
effect;
generated
vapor
heats
the
next
effects
at
lower
pressures.
-
Separation:
Vapor–liquid
separators
ensure
clean
condensate
recovery
and
stable
circulation.
-
Control
of
Concentration:
Inline
density/conductivity
triggers
discharge
or
recycle
to
meet
target
TDS/solids.
-
Utilities
&
Emissions:
Final
vapor
condenses
in
the
surface
condenser;
non-condensables
are
removed
by
the
vacuum
system.
