    Justificación Ptar

    Uploaded by

    Ana Yulieth García García
    The document discusses justification for minimum approach velocities in bar screens and preliminary wastewater treatment processes. It references several sources that recommend minimum velocities of 0.45 m/s to prevent grit deposition in bar screen channels, and velocities between 0.6 to 1 m/s in preliminary treatment channels. It also recommends bar screen channels be 2 to 3 meters in length, and clarifier retention times of 1 to 3 hours.
