Settling Tank - Launders & Trough


1. Launders

    For 3 tank service at Qp = 10 mgd,

    q = 1.29 ft3/s

    b1 = 1'



    For 4 tank service at Qp = 10 mgd,

    b1 = 1'

    Qp(mgd) # of Tanks # of Launders b1(ft)

    q(ft3/s) y1(ft) y2(ft)

2. Trough

    For 3 tank service at Qp = 10 mgd,

    W = 2'

    Qp(mgd) # of Tanks W(ft)

    z1(ft) z2(ft)

    Depth of trough = 1.5' > 1.02'

    Outlet box size = L W D = 2.5 2.5 3'
