    COST · up to $1M a year

    Wood panel & board plants

    Wash and process water loaded with fibre, resin and grit.

    PRODUCTIVITY · no clogged lines

    Metals & steel

    Mill scale and heavy sludge out of rolling and processing water.

    PRODUCTIVITY · no unplanned stops

    Food & agri processing

    Scale and solids out of process water, around the clock.

    ENVIRONMENT · less water, less chemical

    Process water reuse

    Take the solids out so the water goes back into the process.

    How it works

    Gravity does the work

    Four steps, repeated around the clock. Nobody touches the filter.

    Animation: media advancing, solids to the bin, clean liquid to the tank

    Filtering

    1. Even distribution

      The liquid enters a header box that spreads it evenly across the media.

    2. Solids captured

      Held between two sealing wheels, the media catches the solids. Gravity pulls clean liquid through.

    Self-cleaning

    1. Automatic cycle

      As the level rises, a float starts the cycle: fresh media rolls in, loaded media rolls out to the bin.

    2. Clean liquid back

      Filtered liquid collects in the tank below and returns to your process.

    1. Water-tight seal wheels — Hold the media edges — nothing bypasses.
    2. Inlet + header box — Spreads the flow evenly across the media.
    3. Easy-load media tray — A fresh roll drops in from the side.
    4. Clean-liquid tank — Filtered liquid returns to your process.
