Welded single-effect vacuum evaporator with forced circulation engineered for industrial wastewater reduction, brine concentration, and ZLD pre-concentration. Operating under vacuum lowers boiling temperature, while high-velocity circulation improves heat transfer and mitigates scaling—delivering stable throughput, robust operability, and straightforward maintenance.
Live steam heats the circulating liquor in the main heater; vapor generated in the separator is condensed under vacuum. High circulation rates stabilize ΔT/LMTD, limit deposition on tubes, and keep capacity steady across varying wastewater chemistries. Optional TVR (thermo-vapor recompression) can improve thermal efficiency.
PLC/HMI with closed-loop control of level, pressure, ΔT, and conductivity; interlocks for vacuum/NCG handling, pumps, heaters, and condensate quality guard. Alarm/event historian and remote diagnostics available.
Wetted parts in SS316L/duplex (Ti/Hastelloy optional). Large clean-outs, removable heads, CIP provision, and anti-scale dosing support long campaigns and fast turnarounds.
| Parameter | Typical Range* |
|---|---|

| Shell pressure (vacuum) | ~8–25 kPa(abs), duty-dependent |
| Steam economy | ~1.0 (SE); up to ~1.5–2.2 with TVR/heat recovery |
| Circulation velocity | High to limit scaling and stabilize ΔT |
| Condensate quality | Polished for reuse or compliant discharge |
| Materials | SS316L / duplex; Ti/Hastelloy on request |
*Actual performance depends on feed chemistry, fouling tendency, and heat-exchange design.
It handles higher solids and variable wastewater better, keeping tubes clean with shear and stable heat transfer.
Yes. Adding TVR and heat-recovery exchangers raises steam economy; MVR can be integrated in hybrid upgrades.
Absolutely—use as a concentrator ahead of crystallization/solid handling to minimize liquid discharge.
