<strong>Zero</strong> <strong>Liquid</strong><br />
<strong>Discharge</strong> <strong>Solutions</strong>
<strong>Zero</strong> <strong>Liquid</strong> <strong>Discharge</strong> Overview<br />
Praj is a process engineering company with deep understanding of various industrial processes and related<br />
systems. Praj delivers End-to-End solutions in <strong>Water</strong> & Wastewater Treatment for varied applications including<br />
Physico Chemical Treatment Conventional Biological Treatment Advanced Biological Treatment<br />
Concentration by Evaporation Separation Scrubbing by Distillation and many others.<br />
Evaporation is a process of vaporization of a solvent from a solution in order to increase the concentration of the<br />
solute. Building on its expertise, Praj offers concentration solutions using energy efficient ECOVAP range of<br />
evaporation systems.<br />

ECOVAP FF :<br />
Falling Film Evaporator<br />
Falling Film Evaporator with<br />
boiling inside the tubes.<br />
The feed of the evaporator is<br />
fed to the top of the Calandria<br />
through efficient liquid<br />
distributors. Steam is given on<br />
the shell side. The<br />
concentrate is collected at the<br />
bottom. The same operation is<br />
repeated in multiple effects to<br />
achieve steamy economy.<br />
ECOVAP SF:<br />
Special Falling Film Evaporator<br />
Special liquid distribution system<br />
is used to get desired wetting<br />
rate in the tube. Indentical in to<br />
falling film tubular type<br />
evaporation with additional<br />
benefit for reduced scaling and<br />
fouling. The equpment is<br />
unaffected by transit pressure<br />
and gives a uniform liquid<br />
distribution with non-clogging<br />
mechanism.

ECOVAP FC :<br />
Forced Circulation /Flash<br />
Evaporator<br />
The liquid is heated in a<br />
heat exchanger and<br />
flashed in a flash vessel to<br />
achieve desired<br />
concentration. Multiple<br />
pass are provided to get<br />
required flow rate.<br />
Evaporative Crystallization<br />
can be efficiently achieved<br />
in ECOVAP FC.

ECOVAP FB* :<br />
Fluidized Bed Evaporator<br />
A revolutionary 'Self-Cleaning' Fluidized Bed Evaporator in<br />
which, fluidizing media (metallic, ceramic or glass) is added<br />
to impart gentle scouring action on tube surface, while<br />
moving with the liquid to be evaporated. Scouring action<br />
keeps the tubes clean. Media de-fluidized in the top<br />
disengagement zone before being recirculated.<br />
Benefits of ECOVAP FB*:<br />
No loss in production time since down time is virtually nil.<br />
Maintenance cost is nil since frequent CIP is not required.<br />
Standby unit, related piping are not required.<br />
Less initial investment due to lower heat transfer areas<br />
Less floor space.<br />
