Product Description
MVR Falling Film Vacuum Evaporator For Waste Water Treatment
Engineer-to-order MVR (Mechanical Vapor Recompression) falling-film vacuum evaporator for industrial wastewater treatment. Thin-film boiling under vacuum protects heat-sensitive streams, while recompressed vapor duty recycles latent heat to deliver low OPEX, deep concentration, and stable 24/7 operation--ready for integration with crystallization and ZLD solids handling.

Key Benefits
  • Energy saving: Electric-driven MVR minimizes fresh steam after start-up.
  • High recovery: Concentrates high-TDS/COD brines; enables chemical desalination and salt recovery.
  • Product protection: Low ΔT falling film limits thermal degradation and foaming.
  • Scaling control: Optimized ΔT/LMTD, uniform film distributors, antiscalant dosing, and CIP-ready design.
  • Fully automatic: PLC/HMI recipes, alarms, historian, and remote diagnostics for 24/7 uptime.
Process & Thermal Economy
Secondary vapor is mechanically compressed to raise saturation temperature and reused as the heating medium. Even film distribution over vertical exchangers maintains high heat-transfer coefficients; controlled residence time, pressure, and ΔT setpoints deliver predictable concentration with low specific energy.
Materials & Cleanability
Wetted parts in SS316L/duplex (Ti/Hastelloy optional). Drainable layouts, large access for inspection, validated CIP, and elastomer selections suited to chlorides, solvents, acids/alkalis.
Process Overview -- Wastewater to ZLD
Flow: feed conditioning → falling-film MVR evaporation (vacuum) → condensate polishing → crystallizer → centrifuge/dryer → solids discharge/ZLD
  • Feed conditioning: screening/filtration, softening or pH trim; antiscalant for Ca/Mg/Si control.
  • MVR falling film (vacuum): VFD compressor sets ΔT; shell vacuum defines boiling point.
  • Condensate polishing: filters/RO/AC to reuse or discharge spec (conductivity/TOC guard).
  • Crystallization & solids: DTB/OSLO or FC crystallizer -> centrifuge/dryer -> compliant solids discharge.
  • Automation: start/stop recipes, load following via VFD, scheduled CIP windows.
Key Components
  • Falling-film evaporator body with film distributors and vapor-liquid separator
  • MVR mechanical vapor compressor (turbo/Roots) with VFD for ΔT/capacity control
  • Surface condenser, vacuum/NCG handling, preheaters/heat-recovery HX
  • PLC/HMI/SCADA; instrumentation (T/P/flow/cond/level) with historian
  • CIP skid; antiscalant dosing; optional condensate polishing filters/RO
Performance & Sizing
Parameter Typical Range*
Operation Continuous, 24/7 (vacuum duty)
Electric use (MVR) ~15-40 kWh per ton of water evaporated
Fresh steam demand Very low after start-up (backup/ancillary only)
Shell pressure ~6-25 kPa(abs), duty-dependent
Turndown 50-100% with stable ΔT and quality
Materials SS316L / duplex; Ti/Hastelloy on request
*Actual performance depends on feed salinity/COD, fouling tendency, compression ratio, and exchanger design.
FAQ
Can it integrate with our existing membranes for ZLD?
Yes--RO/NF pre-concentration upstream with MVR + crystallizer downstream is a proven ZLD configuration.
How do you manage scaling on difficult brines?
Pretreatment, optimized film ΔT/velocity, antiscalant dosing, and scheduled CIP based on online fouling indicators.
What condensate quality is achievable?
Low conductivity/TOC suitable for reuse after polishing; quality guards ensure compliance with site limits.
