MEE Multiple Effect Evaporator for Effluent Treatment
Hanpu’s Multiple Effect Evaporator (MEE) provides a proven, energy-saving solution for concentrating industrial effluents and reducing disposal volumes. By cascading effects under vacuum, the system reuses latent heat, cuts steam demand, and delivers stable performance across challenging wastewater streams from chemicals, pharma, textiles, food & beverage, pulp & paper, and more.
Lower Utility Cost
Multi-effect heat reuse and optional TVR/MVR integration improve steam economy and reduce cooling water load.
High Availability
Robust falling-film configuration, anti-scaling design, and online cleaning strategies extend continuous run time.
Quality & Compliance
ISO-aligned fabrication, SS304/SS316L contact, pressure vessel codes, and full instrumentation for traceable operation.
Smart Control
PLC/HMI with flow, temperature, pressure, level, and conductivity control; historian for OPEX tracking.
How It Works — Falling-Film Multi-Effect Under Vacuum
- Feed & Preheat: Effluent is metered and preheated using clean condensate to save live steam.
- Effect 1 → Effect 2 → Effect 3: Live steam heats the 1st effect; generated vapor heats the next effects at lower pressures.
- Separation: Vapor–liquid separators ensure clean condensate recovery and stable circulation.
- Control of Concentration: Inline density/conductivity triggers discharge or recycle to meet target TDS/solids.
- Utilities & Emissions: Final vapor condenses in the surface condenser; non-condensables are removed by the vacuum system.
