1.4 Optical radiation
Light is essential for humans. However, in some cases employees may be exposed to too much "light"
during their work, which may damage eyes and/or skin. For this type of situation, the EU Directive
2006/25/EC on artificial optical radiation (1) is intended. This describes what effects can occur and what the
exposure limit values are. The term optical radiation includes the visible, ultraviolet and infrared spectrum.
The term light is a looser term that generally refers to the visible part of the optical spectrum.
Optical radiation is part of the family of electromagnetic radiation (EM radiation). The electricity network
emits EM-fields with a very large wavelength. If we shorten the wavelength, we end up with the long wave,
medium wave, short wave, ultra short wave (FM radio) on TV, GSM, microwave and radar. The following is
the optical area starting with the far infrared. After the infrared, the (fairly narrow) visible area follows,
followed by the ultraviolet, which cannot be seen with the human eye. After the hard UV-C, the optical area
and also the non-ionizing part of the EM-spectrum ends. This is followed by the ionizing region with X-ray,
gamma and cosmic radiation.

1.5 UV lamp types
UV lamps (ultraviolet) radiate optical radiation in, among others, the range between 200 nm and 400 nm on
which the name "UV lamp" is also based. Low pressure (incl. Amalgam) UV lamps produce UV radiation
with a wavelength of 253.7 nm where medium pressure UV lamps radiate at a wide spectrum of
wavelengths (see graph with spectral data). Depending on the type of UV lamp, energy is also emitted in
the visible area of the electromagnetic spectrum:
- Low pressure (LP) UV lamps: blue light (400 nm)
- Low pressure (LPHO) UV lamps: blue light (400 nm)
- Amalgam UV lamps: blue light (400 nm)
- Medium pressure (MP) UV lamps: white light (400 nm - 750 nm)
UV lamps contain a small amount of mercury that is responsible for the UV radiation produced.
A properly working UV lamp needs a certain operating temperature in order to function reliably and
efficiently, with the lamps used in the VGE Pro UV series these temperatures are as follows:
- Low pressure (LP) UV lamps: approximately 45 °C
- Low pressure (LPHO) UV lamps: approximately 45 °C
- Amalgam UV lamps: approximately 95 °C
- Medium pressure (MP) UV lamps: 600 °C - 900 °C.
Spectral data of the medium pressure UV lamps:

1.6 UV disinfection
For non-chemical disinfection of liquids, disinfection with UV-C radiation is a proven and reliable technology
that has been used since the beginning of the 20th century. From around the middle of the 20th century, the
application of UV disinfection on liquids has seen a sharp increase because it then became possible to
produce good quality UV-C lamps on a large scale. The discovery of the by-products produced by chemical
disinfection of water also led to a strong growth in the demand for UV-C radiation for the disinfection of
(drinking) water.
UV radiation (see also the section on optical radiation) can be divided into four main categories: UV-A, UV-
B, UV-C and vacuum UV. The UV-C spectrum (wavelength range of 200 to 280 nanometre) is the most
effective range for controlling microorganisms. UV-C radiation is capable of causing permanent damage to
microorganisms. Each type of microorganism requires a certain amount of UV-C energy (UV fluence, also
known as the UV dose) for the disinfection process to be successful. The microorganisms must be directly
and long enough exposed to UV-C radiation, so that the radiation can penetrate the cell wall of the
microorganism to damage the DNA (deoxyribonucleic acid).
Depending on the intensity of the UV-C radiation, it only takes a short time (in some cases a fraction of a
second) to penetrate the cell wall, irreparably damage the DNA and inactivate the microorganisms in the
water . This causes the reproductive mechanism of the microorganisms to be damaged and in some cases
even killed.
UV-C disinfection is a non-selective process, as is the case with certain chemical disinfection processes.
UV-C disinfection can be used against bacteria, viruses, fungi, yeasts, algae and (chlorine-resistant)
protozoa.

2.5 Handling of UV lamps and quartz sleeves
The VGE Pro MP UV systems are equipped with medium pressure UV lamps and quartz tubes, the quartz
parts must be clean when they are put into operation.
If a UV lamp comes in contact with the skin, traces of grease remain on the lamp. When the UV lamp is
switched on, the traces of grease that remain behind block the light that wants to shine out of the lamp.
Because light is converted to heat, it will become very hot at the location of the grease (or other
contamination) and the lamp will burn out at this location.
To prevent the UV lamps and clean quartz tubes from being grabbed with bare hands, a set of white fabrics
and lint-free gloves are included with every delivery of a new UV system.
The supplied gloves are intended to prevent UV lamps and quartz tubes from
remaining clean. These gloves offer no protection against cuts due to breakage of a

Installation & User Manual
2.6 Quartz tube breakage
To protect the UV lamps from the water, they are positioned in quartz tubes in the irradiation chamber. To
ensure that the UV-C light emitted by the lamps is radiated in the liquid to be treated with minimal losses,
high quality quartz tubes have been used. Quartz tubes should be handled with care and should not be
exposed to large forces due to the risk of breakage.
During service work with quartz tubes, protective gloves and eye protection (preferably a face mask) must
be worn to prevent possible injury.
The quartz tubes built into the irradiation chamber are robust and can handle high water pressures.
However, there are a number of reasons why quartz tubes can break during the UV-C treatment process:
- The water pressure is higher than the specified maximum pressure for the irradiation chamber;
- Water hammer, pressure change in a very short time;
- Fixed parts/objects that are led through the irradiation chamber with the water;
- Overheating of the irradiation chamber;
- Mechanical vibrations of the pipe network in which the irradiation chamber is mounted;
- At high water flow rates through the irradiation chamber, possibly causing vibrations due to cavitation.
If a quartz tube is damaged or broken, the UV system must be switched off by removing the plug from the
socket. Stop the flow through the irradiation chamber by turning off the pump and/or closing valves in front
of and behind the UV irradiation chamber and draining the water from the irradiation chamber.
Follow the instructions in this manual for removing the UV lamp and quartz tube and opening the irradiation
chamber and carefully remove any possible quartz tube remains. Carefully follow the instructions for
rebuilding the irradiation chamber and starting the process.
Warning!
Broken quartz tube parts can be very sharp and should not end up in the process
water. The user of the UV installation must therefore take measures to ensure, in
the event of a quartz tube break, that quartz tube parts cannot cause damage if they
end up in the process water.
If a quartz tube (or several) in a UV system cracks or breaks, the quartz tube and
the relevant UV lamp connector will be filled with water. The speed with which this
happens depends on the water pressure and water supply. Since the UV-lamp
connector cannot stop the water, water will flow out of the UV system. The amount
depends on the water pressure and water supply, which means that the space
where the UV system is mounted can be filled with water.
That is why we recommend the area where the UV system is located:
- regularly check (for example daily) for water;
- provide the room with a monitoring system that can register water on the floor
with a reporting system and/or pump connected to it.
