Components Description - Ozone Solutions Waterzone Series Installation & Operation Manual

Components Description

1. Ozone Destruct Unit: Safely converts off-
gassed ozone into oxygen using a catalyst ma-
terial. The destruct unit uses a heater band to
keep the catalyst bed warm. This is to ensure
no moisture condensates on the catalyst. As
long as the Waterzone is connected to electri-
cal power, this canister should be warm
(sometimes hot) to the touch.
2. Emergency Stop Push Button: Allows you to
easily turn the system off quickly by pushing
this switch.
3. Air Vent: Safely removes all off-gassed ozone/
oxygen from the system. The gas flow from
this vent must be vented to a safe outdoor loca-
tion or into an ozone destruct unit.
4. Ozone Injection Pump: This pump creates the
pressure differential necessary across the ven-
ture injector for ozone injection. This pump
should be operating any time the Green Pump
light on the control panel is ON.
5. Injection Inlet Pressure Gauge: Indicates water
pressure on the inlet side of the venturi injec-
tor. This pressure should be at least 20 PSI
higher than the injector outlet pressure gauge.
Any time the ozone injection pump is running
this pressure gauge should be higher than the
injector outlet pressure gauge.
6. Venturi Injector: A Venturi Injector is used to
pull the ozone into the water using a vacuum
and mix this ozone gas into water very effi-
ciently. For the venturi action to occur, a mini-
mum pressure differential of approximately 20
PSI must be maintained. The differential is
determined by figuring the difference between
the pressures indicated at the inlet and outlet of
the Venturi Injector. The outlet pressure is
equal to Contact Tank pressure, and basically
indicates the pressure exerted on the Ozone
Injection System by the outside source. The
inlet pressure will increase or decrease along
with this pressure, but a constant differential
will be maintained as long as the Injector
Pump is operating properly.
7. Water Trap: These units prevent water from
flowing with the gas stream to the ozone de-
struct unit, and potentially the ozone generator
(in a reverse flow situation). Any water that
may flow with these gas streams will be
trapped in the bowl of the water trap and safe-
ly drained out via tubing to a floor drain.
8. Tank Pressure Gauge: Indicates water pres-
sure on the outlet side of the Venturi Injector.
This pressure will be equal to the contact tank
pressure and basically indicates the pressure
exerted on the ozone injection system by an
outside source. This pressure should be at
least 20 PSI lower than the injector inlet pres-
sure gauge.
9. Contact Tank: This tank mixes the ozone gas
with the water to be treated. Using baffles and
specific inlet/outlet design maximum mass
transfer efficiency of the gas to water is
achieved. While most ozone is dissolved into
the water, some ozone/oxygen will off-gas
through the vent in the top of this contact tank.
10. Water Inlet: Connection for incoming water.
11. Flow Switch: The Flow Switch recognizes
there is water flowing through the tank and
tells the controls in the system.
12. Water Outlet: Connection for effluent water.
13. Injector Pump/Destruct Unit Receptacle: This
is where the injector pump and destruct unit
get their power from the system. The Destruct
unit side is always electrically while the pump
is on a controlled contactor and powers on
when system is running.
14. High Pressure Check Valve: This check valve
is to make sure that water does not flow back
up the ozone line.
15. Low Pressure Check Valve: This check valve
is a secondary to the high pressure check
valve that if it fails it will keep water from
flowing up the ozone line.
16. Water Outlet Ball Valve
17. AS-500 Probe: Measures dissolved ozone lev-
el exiting the contact tank.
