parameters?
Give this one a try later!
VSR, gas production, and VA
T/F: To the left of the breakpoint, the Cl2 residual is free.

mW: milliwatt, unit of power. Indicates the amount of UV power or energy
delivered per unit of time.
S: seconds, time period of which UV radiation is supplied.
cm^2: square centimeters, represents the are over which the UV radiation is
distributed or applied.
Minimum VSR necessary to meet vector attraction reduction when land-applying
either class A or B biosolids.

When the suction reservoir is below the pump, what 3 head components must be
added together to calculate TDH?
Give this one a try later!
Suction, discharge, and friction.
Why is a longer MCRT needed when nitrifying an activated sludge system?
Give this one a try later!
Because nitrifiers are slow growers
