THE VACUUM INDUCTION SYSTEM
THE CONTACT / DEGASSING SYSTEM
An optional contact / degassing system is available which virtually eliminates
the air bubbles present in the ozonised water stream thereby avoiding air
entering the pool through the water inlet system.
The system comprises of a contact tank fitted with an external combined
level control and venting valve which vents the excess air and any ozone gas
present to an ozone gas destruct unit which destroys any ozone gas before
venting to the atmosphere.
The ozone gas destruct unit consists of a wall mounted container which is
filled with activated carbon through which the vented air from the degasser
unit is passed.
Any excess ozone gas present reacts with the carbon and is converted back
to oxygen before being released to the atmosphere.
It is strongly recommended that a degassing system is adopted as
entrained air entering the pool can be visually unacceptable and could
have a bleaching effect on pool liners or covers.

The ozone induction system is comprised of an air to water venturi injector
which is driven by a water booster pump.
The booster pump takes its supply from the filtered water return pipe to the
pool and increases the pressure of the water that then passes through the
venturi injector. The design of the injector then uses this pressure to induce a
vacuum at the side connection of the unit which is connected to the ozone
generator via a water trap assembly.
It is the creation of this vacuum that draws the air through the ozone
generator and then into the injector where the ozone gas then mixes with the
water stream.
The amount of suction created by the injector can be controlled by varying
the water flow from the booster pump by adjusting the valve fitted in the
pump discharge line. Alteration of the airflow through the generator also
controls the amount of ozone gas produced.
