    Reuse Pipeline Modification For Flow Improvement

    Uploaded by

    Angel Silva Vicente
    The effluent pond level was becoming a major concern due to restricted water discharge from the pond. An investigation found that non-operational end users were limiting discharge to 66 m3/hr from the designed 87 m3/hr. Installing a booster pump and modifying piping (Option 2) was selected as the best solution to significantly increase flow up to 35 m3/hr more. The project was approved and implemented, allowing maximum water delivery as needed with operational savings estimated at $200k over 10 years.

    SUCCESS STORY

    Overview
    Effluent Pond is the final point in the Plant
    Waste Water System. By term ‘Effluent’, it means
    water that is no longer needed or suitable for its most
    recent use, but can be returned to the water cycle with
    minimal environmental issues. The effluent pond is the
    central monitoring basin of the effluent water for final
    discharge to reuse for aquaculture or agriculture.
    The Reuse Pump is the transport machine
    utilized to distribute water for re-use from the Effluent
    Pond to its end users, in particular the Boiler Area, FA
    Handling System, Coal Shelter Dust Supp. System, Coal
    Jetty Dust Supp. System, Ash Runoff Sump, and the
    major customer, Aquaculture Ponds. There are two (2) units at
    100% capacity each.

    The Dilemma
    During the first quarter of 2018, Effluent Pond level has
    become one of the major areas of concern that the Operations
    team has always been monitoring because of its recurrent
    critical level status which may pose environmental issues
    (overflowing). After a series of tests and monitoring by the
    Performance Team on May 2018, it was found out that the
    non-operational of the end users other than Aqua pond have restricted
    (to about 66 m3/hr) the existing system in discharging the water from effluent pond at a rate the Reuse Pump is originally
    designed to deliver (87 m3/hr).

    The Solution
    Increasing the Reuse Pump flow capacity thru
    implementing modifications to the current piping system will
    give permanent and long-term solution. After a series of
    engineering analysis and consolidation of gathered data by
    the Performance Team, a set of potential solutions were
    presented on August 2018 and evaluated based on the
    resulting improvement in flow and the corresponding
    estimated first costs and operational costs. Major comparison
    points are shown in the following table and figure.

    It was agreed together with other O&M sections to select

    further reduce system resistance whenever higher flow to Aqua pond
    is desired – in fact this results to the highest gain of flow with up to 40 373.20
