Product Description
Energy Saving MVR Evaporator PLC Engine Zero Liquid Discharge Wastewater
Engineer-to-order MVR (Mechanical Vapor Recompression) evaporator for ZLD wastewater treatment. The system recycles latent heat via mechanical recompression to minimize utilities, while a PLC control engine orchestrates continuous, unattended operation—delivering low OPEX, high recovery, and compliant discharge as solids.

Key Benefits
  • Energy saving: Electric-driven MVR slashes fresh-steam demand after start-up.
  • ZLD-ready: Deep concentration to crystallizer/centrifuge/dryer for zero liquid discharge.
  • Smart automation: PLC/HMI with recipes, alarms, historian, remote diagnostics, and load following.
  • Stable operation: Vacuum low-ΔT duty, optimized ΔT/LMTD and velocity to reduce fouling and foaming.
  • Durable materials: SS316L/duplex (Ti/Hastelloy optional) for corrosive brines and chemicals.
Process & Thermal Economy
Secondary vapor is mechanically compressed to elevate saturation temperature and reused as the heating medium. Tight control of pressure, ΔT, circulation rate, and residence time keeps coefficients high and specific energy low, producing condensate suitable for reuse after polishing.
PLC Control & Safety
Closed-loop control of level/pressure/temperature/conductivity; interlocks for compressor/VFD, vacuum and NCG handling, heater duty, and condensate quality guard. Event/alarm historian and secure remote support enable 24/7 uptime.
Process Overview — ZLD Wastewater
Flow diagram: feed conditioning → MVR evaporation (vacuum) → condensate polishing (reuse) → crystallizer → centrifuge/dryer → solids discharge
  • Feed conditioning: screening/filtration, softening or pH trim; antiscalant to limit Ca/Mg/Si scale.
  • MVR evaporation (vacuum): falling film or forced circulation; compressor discharge sets ΔT/capacity.
  • Condensate polishing: filters/RO/AC to reuse or discharge spec (conductivity/TOC guard).
  • Crystallization & solids: DTB/OSLO or FC crystallizer → centrifuge/dryer → compliant solid disposal or recovery.
  • Automation: PLC recipes for start/stop, CIP windows, and load-following with VFDs.
Key Components
  • MVR evaporator body (falling film / forced circulation) with vapor-liquid separator
  • Mechanical vapor compressor (turbo/Roots) with VFD
  • Surface condenser, vacuum/NCG skid, preheaters/heat recovery HX
  • PLC/HMI/SCADA; instrumentation (T/P/flow/cond/level); alarm & 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)
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 heat-exchanger design.
FAQ
Can this integrate after membranes for ZLD?
Yes. RO/NF pre-concentration upstream with MVR + crystallizer downstream is a standard ZLD configuration.
How is scaling managed?
Through pretreatment, optimized ΔT/LMTD and velocity, antiscalant dosing, and scheduled CIP based on fouling indicators.
What condensate quality is achievable?
Low conductivity/TOC; polishing enables reuse within the plant, reducing freshwater intake.
