Our Medium Pressure UV lamps give more for less


  • They give more disinfection per cm / inches than low pressure lamps.
  • Broad germicidal spectrum that attacks different parts of the microorganism and destroys its repair mechanisms.
  • There is no danger of rejuvenation of the microorganisms that compromise your product later.
  • More efficient in the inactivation of viruses.
  • Easily inactivates microorganisms resistant to other disinfection methods such as chlorine, heat and low pressure UV.
  • It uses much less energy than low pressure UV systems to achieve the same results.


Less UV lamps are necessary to achieve a result equivalent to low pressure


  • Less lamps means a significant reduction in maintenance.

In some cases, 2 or 3 Medium Pressure lamps can replace up to 50 Low Pressure lamps.

Works with cold and hot water, unlike low pressure UV rays


Optimized UV efficiency

  • The high purity quartz disinfection chamber surrounded by a block of air, uses the principles of optical fiber to recycle light photons.
  • The UV photons emitted by the lamp can not penetrate the air block and bounce several times in the water (a phenomenon known in the optical fiber as total internal reflection).
  • Photons of UV light are distributed through the entire volume of water, so that all microorganisms are reached and inactivated.


Reduction of energy consumption


  • The increase in efficiency for each UV photon means that less UV is needed to achieve the same results.
  • Less UV means less energy consumption and longer lamps.


Optimized hydraulics


  • The water flow is synchronized to match the pattern of UV light distribution.

There are no parts, deflectors or brushes in the UV disinfection chamber that can block the UV photons that treat the microorganisms that arrive in the water.


Uniform dose distribution


  • A horizontal UV distribution system and optimized hydraulic engineering ensure that all microorganisms in the water treatment chamber are exposed to a uniform UV dose.
  • The entire volume of water is subjected to efficient disinfection.

It has the ability to dose the rhythm of each lamp. The properties of its software of logic, sensors and controls, allow the automatic adjustment of the dose according to the evolution of the water quality to guarantee the protection in real time. The dose needed to meet any application need is maintained at all times through this reliable approach. The efficient use of UV energy, achieved through the properties of control of the frefuencia of the doses, allows a lower consumption of energy and a greater duration of the lamps.

In the image you can see the cross section of the HODW-O® unit that shows the high level of disinfection achieved by the configuration of the quartz chamber, equipped with thick lampholder tubes that isolate these from the water.


HODW-O® lamps are shorter and reduce the risk of breakage


  • Lamp with lengths of 26.3 cm (10.35 “).
  • Easy to handle


Thick quartz tubes protect lamps and water


  • Quartz chamber with 5 times the thickness of conventional quartz sleeves.
  • There is no possibility of breaking glass or mercury in the water, in the unlikely event of a UV lamp breakage.
  • There are no thin quartz sleeves that can break or replace.


Less mercury


  • Its small size, involves less mercury and less exposure in case of breakage.
  • Some systems use very long lamps that are much more susceptible to breakage. These lamps add the danger of large “spills” of mercury when they break.

ment, offers unattainable results for other UV technologies in the reuse of
wastewater. Incorporated into a tertiary system, the HODW-O® is able to
guarantee protection against bacteria, nematodes, viruses, etc., in wastewa-
ter for subsequent reuse in agriculture, industrial cleaning or gardens.
HODW-O® has been successfully implemented in ZLD liquid zero discharge
projects in the food and heavy industry.
Protection of
Osmosis Systems
HODW-O® CONTINUE HODW-O® as a UV treatment for non-chemical disinfection and dechlorina
tion is a sustainable alternative to chemistry (SBS / SMBS) against Biofouling
and its heavy maintenance burden. The UV technology of HODW-O® is unique
in its ability to disinfect and dechlorinate feed water and production water in a
single non-chemical process. The system decomposes free chlorine and signif-
icantly reduces the combined oxidants of chlorine in water to protect RO mem-
branes. At the same time, high-level sintering technology reduces the biofouling
potential of the membrane by eliminating the potential for anaerobic and aero-
bic bacterial growth.
Elimination and Control
HODW-O® CONTINUE HODW-O® is a cost-effective, safe and efficient method to reduce the biofilm
in the water of the cooling tower. By preventing new biofilm formers from en-
tering the cooling tower water, it has a profound impact on microbial integrity
downstream. It can be a key component of a Legionella control program be-
cause it inactivates both organisms that are resistant to chemicals and organ
isms typically treated with chemicals in a single treatment. • Inactive Legionella
bacteria, as well as other bacteria, algae and protozoa that are resistant to tra-
ditional chemical biocides.
Control of
Invasive Species
HODW-O® CONTINUE In heavy industry, while traditional meshes capture large organisms, larvae of mus-
sels, barnacles, clams and other invasive species settle, grow and block pipes and
exchangers. The resulting reduction of capacity in the energy exchange and pump-
ing, compromises the functionality of the plants. The UV treatment of HODW-O®
has been shown to prevent 99% of fixation and settling at low UV doses.
The HODW-O® solution eliminates the need for corrosive chemicals and is safer
for water and the environment.
• Sustainable and profitable solution
• Meets strict environmental regulations
• Non-corrosive - less chemical fouling and chemical biofouling
• Cleaner surfaces to improve heat transfer
Chemical Free Treatment
Processed water
HODW-O® CONTINUE Our HODW-O® system allows high microbial inactivation without the use of che-
micals for process water, rinse and CIP applications. It achieves high reductions of
microorganisms and is particularly effective against those resistant to chlorine, pseu-
domonas, cryptosporidium and gardia. It also inactivates heat-resistant viruses and
spores. HODW-O® is tested in field tests and validated for the highest standards of
regulation including EPA, FDA and PMO. HODW O® guarantees the safety of water
without adding chemicals and without disinfection by-products. The Cost-Effective-
ness and Environmental Respect of the HODW O® solution offers levels of inactiva-
tion never before reached with other UV systems.
Without Chemicals
HODW-O® CONTINUE HODW-O® high-intensity, medium-intensity ultraviolet light is extremely ef
fective at decomposing free chlorine at undetectable levels, and is a clean
and safe alternative to the activated carbon filter and sodium bisulfite. The
results are reliable and the system is sustainable. It protects the system in-
cluding filters and RO membranes from microbial contamination, reducing
the maintenance load, while providing high level water disinfection and a-
vailability on demand. In addition, HODW-O® is fully compatible with PW
and WFI standards.
Sulphite Reductive
Bacteria Control
HODW-O® CONTINUE The production water of the mining industry, as well as that of Oil & Gas,
contains a large quantity of microorganisms. While the types of organisms
vary widely, the most damaging to this industry are sulfphite-reducing bacte-
ria (SRB). These SRB are present in all the waters manipulated in the mining
or oilfield and they aggravate the deposits converting the sulphate ions into
hydrogen sulfide (H2S). The SRB activity potential is even greater when the
operations are based on the injection of produced water. The working prin-
ciple of HODW-O® has been proven highly effective in controlling these SRB
by improving results.
Active Carbon Substitution
Post A.C. Treatment
HODW-O® CONTINUE Carbon is a breeding ground for bacteria prone to biofouling and, without
intensive maintenance, is subject to costly advances. A HODW O® unit, in-
stalled immediately after the active carbon filter, protects against ruptures
and reduces downstream biofouling, so there is less demand for frequent
and aggressive cleaning. Likewise, in some industrial processes Active Car-
bon can be replaced by an HODW-O® system improving efficiency and ef-
fectiveness, reducing risks.
Cold Disinfection of Water
Equivalent to Pasteurization
HODW-O® CONTINUE The principles of HODW-O® meet the PMO 2009 criteria for water equivalent
to pasteurized, which authorizes UV to replace traditional pasteurization if it
adheres to specific criteria. The principles of HODW-O® comply and is verified
by third-party validation. It obtains pasteurized water equivalent to demand, re-
placing the costly processes of heat pasteurization that consume a lot of energy.
If you currently pasteurize the water in batches, you can join a tank and in this
way you can save energy costs by keeping intact the levels of disinfection obtain-
ed with traditional water pasteurization.
