Continuous Feed: 1600
Gallons/day = 67 gallons/hour =
1.1 gallons/minute
All Pipe Dual Contained
Line Size: 2” – 4” Depending on
facility
Temp = 75 to 85 F
Pressure = Gravity Feed to 30 psi


Pressure = 50 to 110 psi
Water line is at 50 to 75 psi
Temperature is normally 85 F
Temperature will spike to 180 F
when acid injection stops. Water
will fill Acid line and create
Exothermic reaction
Acid

RO Pretreatment
Increase pressure to 50 to 110
psi
Line Size = ½” – 2”
Temperature = 85 F
