Theory of Operation
EcoWater CHC supplies both water treatment and filtration systems.
CHC Water Treatment System-
The CHC Water Treatment System consists of a pump and treatment chamber. As water enters into the
main suction pipe it passes through the basket strainer. The basket strainer is designed to remove any
large particles from the water before it enters the CHC pump. Isolation valves are located at both the inlet
and outlet of the basket strainer and are used to isolate the basket strainer from the water flow during
servicing. The pump utilizes a centrifugal pump to pressurize the water to the required pressure for the
Hydrodynamic Cavitation to occur in the CHC treatment chamber. The CHC treatment chamber consists
of two proprietary nozzles that create a high speed water stream that are aimed directly at the opposing
water stream. As these two streams collide, a vortex is created, it is within this vortex that the
Hydrodynamic Cavitation cloud is created. The pressure regulation valve located on the discharge of the
CHC chamber is used to control the required 2-5 psi back pressure for appropriate operation of the
chamber. As water leaves the chamber it then passes through the discharge pipe and back to the tower’s
sump. A vent may be provided at the top of the discharge pipe, to break any vacuum that could be created
as the water suddenly drops into the sump.

configuration and the technology behind its operation.
Filtration System-
As water is drawn in from the basin it passes through the main suction pipe and passes through the basket
strainer. The basket strainer is designed to remove any large particles from the water before the water
passes to the pump. Isolation valves are placed on both the inlet and outlet of the basket strainer to allow
for isolation of the basket strainer during the required servicing. The water then enters the skid pump.
The skid pump utilizes a centrifugal pump that delivers water to the filtration system. As the water leaves
the pump it passes through a centrifugal separator that removes all heavier than water particles. A timed
purge cycle, removes the debris from the separator and passes it to the drain as needed. Once past the
separator, water then flows back towards the tower while a portion is pulled through a side stream,
automated screen filtration unit. This second stage filter, utilizes a fine screen to filter out any particulate
out of the water stream that may be lighter than water. As the filter’s screen becomes clogged, the
