SCOPE (Continued).
Coalescence occurs as the fluid flows through the filter elements
mounted in the two pressure vessels.
Separated oil collects at the
top of each vessel.
It is discharged by opening a hand operated
valve.
Water processed through the second stage is discharged by
opening a hand operated valve.
The Type A and B oil-water separators are three-stage coalsecent
types.
They are designed to separate and remove non-soluble oil,
solids and entrained air from an oily water mixture.
The system is designed to operate continuously or intermittently.
No chemicals or other additives are needed.
Coalescence occurs as the fluid flows through the filter elements
mounted in three pressure vessels.
Two mini-probes, are located in
each of the first two separator stages.
They provide automatic
discharge of accumulated oil.
Oil builds up in the first (prefilter) and second stages, where
the bulk of the oil is separated.
The mini-probes sense this build
up and signal solenoid operated discharge valves.
The valves open.
Separated oil is dumped into the holding tank.
Oil buildup in the third stage is very small.
This is primarily
a polishing stage.
The water processed through the third stage is
discharged through a solenoid operated valve.
