    Falling Film Multiple Effect Evaporator Equipment For Effluent Treatment

    Falling Film Multiple-Effect Evaporator Equipment for Effluent Treatment
    A modular MEE falling/thin-film system for concentrating industrial effluents and enabling vacuum crystallization or water reuse. Optimized for steam economy, small footprint, and continuous, automated operation across paper-making wastewater, salt-making brines, and diverse industrial streams.

    Lower Utilities
    Each effect reuses the previous effect’s vapor as heating medium, drastically reducing fresh steam per kg water evaporated.
    Clean Operation
    Closed, vacuum operation with mirror-polished tubes mitigates fouling and simplifies CIP.
    Modular & Maintainable
    Skid sections and accessible piping shorten installation and maintenance windows.
    Process Description — Parallel-Flow Example
    Feed enters the first-effect circuit, mixes with circulating liquor, and is heated with live steam in heater H. In evaporator V1, water vaporizes at its boiling point. The liquor then passes to the lower-pressure second effect, where first-effect vapor becomes the heat source. This staged reuse continues across effects, sized per boiling point elevation, allowable ΔT, and duty—maximizing thermal efficiency and minimizing OPEX.
    Structure
    First/second/third-effect heaters & separators, pre-heaters, terminal condenser, vacuum package, feed/circulation/discharge/condensate pumps, and full instrumentation (vacuum, temperature, pressure, flow, level). Optional TVR or MVR modules can further reuse secondary vapors.
    Key Characteristics
    • Evaporation rate: 500 kg/h to 80 t/h.
    • Materials: SS304 or SS316L (others on request).
    • Vacuum, low-temperature operation: Short residence time; gentle to heat-sensitive components.
    • Sanitary internals: Mirror-polished seamless tubes reduce scaling; easy CIP.
    • High concentration ratio: Falling film hydrodynamics handle viscous feeds; short concentration time.
    • Automation: PLC/HMI, interlocks, trending, recipe control.
    • Custom process trains: Configured per feed chemistry, BPE, and client utilities.
    Applications
    Effluent concentration and reuse in paper-making, chemical & pharmaceutical, textile/dyeing, food & beverage, breweries, automotive; RO reject concentration; salt recovery via vacuum crystallization; ZLD pretreatment.
