The Six-Stage Separation and
Filtration Process
Separation
The first stage of separation occurs as material being
vacuumed falls into the debris body. All debris and water
enters the debris body on the front side of the ejector
plate where the heavier solids fall to the bottom.
The second stage of separation occurs as water passes
through the small clearances between the ejector plate
wipers and the debris body to the rear of the ejector
plate. The clearance between the ejector plate wipers
and the debris body is only large enough to allow liquid
and fine solids to pass to the rear of the ejector plate and
will keep larger solids on the front side of the ejector
plate.
The third stage of separation takes place in the settling
area behind the ejector plate where fine solids and water
accumulate to be used for the recycling process. Some of
the debris left in the water will settle to the bottom of this
settling area.
Filtration
The first stage of filtration consists of an oscillating
self-cleaning filter screen inside the debris body in the
settling area behind the ejector plate. The oscillating
motion of the filter screen creates a counter flow and
agitates the debris materials and water around it. This
filter screen includes two self-cleaning spray bars. The
first is a low-pressure spray bar that uses recycled water
and is constantly cleaning the outside of the filter screen.
The second is an internal high-pressure spray bar that
uses fresh water to internally clean the screen. The
second spray bar is used to perform a fresh water flush
and is controlled via the front control panel HMI screen.
The second stage of filtration is performed by the
centrifugal separator (Hydro cyclone) located on the front
tank head of debris body
.
The centrifugal separator is
designed to remove fine debris from the recycled water
via centrifugal action and to continuously return the
filtered debris back into the debris body.
The third stage of filtration consists of a Y-type cast-iron
strainer with a stainless steel filter element that acts as a
last-chance filter prior to water entering the high-pressure
water pump.
