Product Description
Wastewater MVR Evaporation System - Multi-Effect Falling (Thin) Film Automatic 1600 LPH
Engineer-to-order MVR + Multi-Effect falling (thin) film evaporator for industrial wastewater. The 1600 LPH train runs under vacuum with automatic controls (PLC/HMI), delivering high energy efficiency, stable quality, and continuous operation for ZLD and resource recovery.
- Energy-saving core: mechanical vapor recompression with multi-effect synergy to minimize utilities
- Thin-film heat transfer: high coefficient, low ΔT, reduced fouling for saline/organic feeds
- Automatic operation: start/stop recipes, auto-CIP windows, alarm interlocks, remote support
- Continuous duty: redundant critical pumps, online diagnostics, long campaign runs
Typical Applications
High-salinity wastewater concentration, ZLD brine reduction, inorganic salt recovery, chemical & pharma mother liquors, dye/printing effluents, and food process streams requiring low operating costs and consistent quality.
Process Configuration
MVR compressor provides main heat duty; upstream/downstream multi-effect falling film effects boost thermal economy. Optional forced-circulation crystallizer for final salt out.
Controls & Safety
PLC/HMI with historian; closed-loop control of level/ΔT/pressure/cond; power quality & interlocks for compressor/VFD.
Hygiene & Materials
SS316L/duplex for wetted parts; drainable layouts; anti-scale dosing and validated CIP to manage fouling.
Process Overview
- Feed conditioning: filtration/softening, pH trim, deaeration to limit scaling/corrosion
- Evaporation: vacuum falling (thin) film in ME stages; MVR recompresses secondary vapor as heating medium
- Condensate: polished for reuse; conductivity/TOC guard
- Concentrate: routed to crystallizer or sent to downstream handling per ZLD scheme
Key Components
- MVR compressor (turbo/Roots) with VFD and inlet filtration/silencing
- Multi-effect falling-film evaporator bodies, preheaters, condensers, vacuum/NCG handling
- Circulation/transfer pumps with standby; anti-scale dosing & CIP skid
- PLC/HMI/SCADA, instrumentation (T/P/flow/cond/level), historian & remote access
- Optional: forced-circulation crystallizer, centrifuge/dryer for solid salt discharge
Performance & Sizing (1600 LPH model)
| Parameter | Typical Target / Range* |
|---|---|
| Nominal evaporation rate | 1600 LPH (≈1.6 m³/h) continuous |
| Electric use (MVR) | ~15-40 kWh per ton of water evaporated (duty/CR dependent) |
| Fresh steam demand | Very low after start-up (backup/ancillary only) |
| Operating pressure | Vacuum; boiling at reduced temperature to protect organics |
| Turndown (VFD) | ~50-100% with stable ΔT and product quality |
| Availability | ≥95-98% with planned CIP and redundancy |
| Condensate quality | Low conductivity with polish (reuse-ready, app-dependent) |
*Performance depends on feed fouling tendency, compression ratio, heat-transfer area, and control strategy.
FAQ
Can it integrate into a ZLD plant?
Yes--commonly paired with RO/NF pre-concentration and followed by crystallization and solid handling.
How is scaling controlled?
Proper softening/pH control, optimized LMTD/velocity, anti-scale dosing, and scheduled CIP cycles.
Is the system fully automatic?
PLC recipes for start/stop, auto-sequencing, alarms, historian, and optional remote monitoring are standard.
