Incorrect mounting of the lamp holder, the arrow on the lamp base must point with the direction of flow and
not as shown here against the direction of flow.
6.4 Bypass installation
In order not to have to stop the operating process during service work on the irradiation chamber, which
must be opened, it is advisable to place the UV system in a bypass.
Bypass closed for UV system operation
When disinfecting liquids, the full flow must flow through the UV system, if only 1% of the flow does not flow
through the irradiation chamber, a log 2 reduction of microorganisms is the maximum attainable. An
exception to this is a process in which the water is circulated in which only a part flows through the UV
system, which controls the amount of microorganisms required for the specific process.
When reducing the bound chlorine (chloramine) in swimming pool water, the UV system must be
dimensioned for the total circulation flow that goes through the water treatment. If the UV system is
dimensioned for a partial flow of the total flow, the reduction of the bound chlorine will take longer or even
will be unrecordable. Always dimension a UV system to be used in swimming pools at the full circulation
flow rate and install the UV system in such a way.
6.5 Corrosive water
The VGE Pro INOX systems are made of stainless steel in the quality 316L, which is a material that is
excellent for applications in, among other things, the drinking water industry or swimming pool installations
due to the low corrosive properties of the water.
VGEM000-GB192
Pag. 40/68
If the water to be treated is no longer flowing through the UV irradiation chamber,
this water is no longer disinfected/treated. The following measures must be taken:
-
Alternative (chemical) disinfection of the water;
-
Do not use and drain the water;
-
Stop water flow;
-
No UV irradiation of the water for a short time is no problem (circulation of
swimming pool water where chloramine is reduced), no measures.
