We are committed to the dissemination of systems and clean technologies that provide added value, more competitive investment costs and
simplification of our clients' facilities, and all this without putting greater pressure on the environment.
The implementation of consolidated technologies such as UV, Ozone, UF and other more innovative ones such as Advanced Oxidation Processes, compact
Primary filtration and high-performance deodorization systems using UV+catalysts allow us to offer more efficient solutions: lower consumption
energy and lower OpEx.
UV - Ultraviolet
ultraviolet (UV) light provides rapid and efficient inactivation of microorganisms through a
physical process. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV light, they become unable to reproduce
and infect.
The UV energy used for water treatment is classified into two primary levels according to its wavelength: 254nm and 185nm. For applications of
Disinfection uses the wavelength of 254 nm. A single wavelength is used for TOC reduction and chlorine destruction applications.
Light is electromagnetic radiation or radiant energy traveling in the form of waves. UV light is invisible to the human eye, it lies between visible light and X-rays.
in the electromagnetic spectrum.
UV light penetrates the external cell wall of microorganisms, passes through the cell body, reaches nucleic acids (DNA and RNA) altering their
genetic material in a process called thymine dimerization. The microorganism becomes "inactivated" and loses the ability to reproduce or infect.
UV disinfection is a clean, non-chemical process and therefore does not produce any waste.

Ozone
ozone is a triatomic form of oxygen and is commonly represented by O3 . Ozone is a
unstable gas with a very short half-life, which means that it reacts and disappears very quickly, therefore, it must be generated and dissolved
in the water «in situ».
Ozone is essentially made up of oxygen. When an oxygen molecule (O2) is exposed to a high electrical voltage, the oxygen molecule
(O2) splits into two oxygen atoms (O1). The oxygen atom (O1) combines with the oxygen molecules (O2)
ozone (O3) is formed. When ozone reacts with other substances, the simple oxygen atom (O1) separates from the ozone molecule
(O3), which is converted back into an oxygen molecule.
In the atmosphere, ozone is generated when ultraviolet light splits oxygen molecules into individual oxygen atoms (radicals). When ozone is generated
Industrially, it is produced with cold plasma (also called dielectric barrier discharge method) or corona discharge.
Cold plasma (dielectric barrier discharge) is defined as a gas that is partially ionized and is generated at room temperature or below.
The ionization of the gas, e.g. pure oxygen, takes place between two electrodes that are separated by an insulating barrier (dielectric barrier). When the
plasma, oxygen molecules split into individual oxygen atoms which then recombine with unreacted O2
and form ozone (O3).
The difference between the ozone generators on the market lies in the arrangement and design of the high-voltage electrodes. Thetemperature of
gasis an important factor when it comes to the effectiveness of ozone generation. The gas temperature is usually controlled by cooling water
and the colder the water, the better ozone synthesis will work. Ozone reactors can only be built with a few materials due to high reactivity
of ozone. Materials such as stainless steel, aluminum, glass, polytetrafluoroethylene or polyvinylidene fluoride can be used. Viton can also be used,
but only for a limited time and with the restriction of constant mechanical forces and absence of humidity.

AOP – Advanced Oxidation Processes
Advanced Oxidation Processes are those processes that involve the formation of hydroxyl
radicals (OH-)oxidation potential (E = 2.8 V) much higher than that of other traditional oxidants (ozone, 2.07 V; hydrogen peroxide, 1.78 V; chlorine dioxide, 1.57 V,
and chlorine, 1.36 V)
These processes are suitable for destroying chemical environmental contaminants such as pesticides, industrial solvents and traces of drugs,
among others.
Chemical contaminants can be treated with UV (either as a single treatment or in combination with an oxidant). We have solutions designed to treat
chemical contaminants, either by UV photolysis or by UV oxidation.
The drinking water sources we rely on daily are increasingly exposed to chemical contamination. Many of these contaminants have been proven to be harmful or carcinogenic and must be
treated and removed before the water can be considered safe for consumption.
These contaminants can come directly from human sources, such as industrial manufacturing, agricultural runoff, and wastewater discharges, or they can originate from natural sources,
such as chemicals that cause taste and odor in water generated by the proliferation of algae and bacteria.
Our expertise is through UV oxidation, that is, producing a photochemical reaction by, for example, combining hydrogen peroxide with UV light to generate strongly oxidizing hydroxyl
radicals that oxidize the contaminant, breaking the chemical bonds between molecules and reducing the potentially hazardous chemical to its safe, elemental components. Other typical
examples of UV-based advanced oxidation processes include UV+Ozone, UV+Persulfate, and UV-Vacuum.
UV light, as part of a multi-barrier system, acts to simultaneously inactivate pathogens and destroy contaminants. This is achieved
without the formation of potentially dangerous disinfection byproducts, including THMs (formed when using chlorine) or bromate
(formed through the use of ozone).

Microfiltration "Orso" Textile Filter
This type of filtration has a 100% submerged disc design that uses a different type of filter fabric than that used in conventional 65% submerged disc
filters. The cleaning process is by suction rather than backwashing, so in this case, impurities are captured from the outside. Exceptional filtration results can be achieved
by combining it with our FDi and FDGi Disc filter series.
Principle (OUT -> IN direction)
Untreated water, including impurities, flows into the filter chamber. The segments contain a filter that includes the textile filter cloth, forming individual discs. The entire system is 100%
submerged. The water passes through the textile filter cloth and is collected in the central collector, retaining impurities on the surface of the cloth.
Discs up to 2.2 m in diameter.
Filtration operates continuously.
Advantages
• Continuous filtration even during backwashing
• High capacity in a small space
• Larger filtration surface per disc
• Lower energy consumption during backwashing
• Low operating costs
• No possibility of sedimentation in the filter chamber
• No aerosol contamination during the backwash cycle
• Exceptionally low noise pollution
• Long service life of the filter fabric - no risk of fabric breakage
Design Versatility
• Depending on the location - in a concrete channel or steel tank
• Depending on the required filtered water quality
• Depending on the sludge discharge method - by gravity or pump

Microfiltration "Clever" Disc Filter
This disc filter will play an important role, especially in retrofit/retrofit applications, where there is a significant need to increase filtration capacity in existing installations with limited space.
Combined with design improvements, it provides a new level of filtration.
Principle (Flow Direction IN -> OUT)
The basis of the entire filtration process is the filter segment, which is covered with a filter cloth selected based on the required quality of the filtered outlet water.
The filter cloth is available with mesh sizes starting at 5 μm. The hollow structure of the cassettes reduces the load on the shaft and extends the life of all mechanical parts.
Water entering the interior of the filter segment flows through the cloth, while fine impurities are trapped. The segments attached to the disc shaft form individual discs.
Filtration operates continuously.
Advantages
• Smaller size while maintaining the same number of discs
• Filtering capacity increased by 25%
• Innovative backwashing system that saves backwash water consumption by 25% and energy consumption by 40%
• Increased backwash efficiency
• Easy replacement or cleaning of ceramic nozzles
• Most spare parts interchangeable between FD/FDG and FDi/FDGi
• Unique and advanced backwash logic optional
Design Versatility
• Depending on location - in a concrete channel or storage tank steel
• depending on the required quality of the filtered water
• depending on the sludge discharge method - by gravity or by pump

Microfiltration Drum Filter
Principle (flow direction IN -> OUT)
The treated water flows by gravity into the drum filter collector equipped with CLI-CLO cartridges. The filter assembly is at rest at the beginning of the filter cycle; that is, it does not rotate.
Impurities larger than the mesh size are trapped inside the filter cartridges.
As impurities are trapped on the filter cloth, the flow rate decreases and the water level in the drum gradually rises. When the water level probe is activated, the filter drum begins to rotate
and backwashing begins. High-pressure backwash nozzles direct the trapped impurities into the sludge tank.
When the water level drops to the preset minimum level and the backwash cycle ends, the unit stops rotating and filtration returns to its maximum capacity at the minimum level.
The filtration cycle repeats. Filtration continues without interruption.
Advantages:
• Significant improvement in treated water quality
• Reduced space requirements
• Low investment and operating costs
• Fully automated operation
• Considerably increased treatment reliability
• High resistance to wear and damage
Design versatility
• Depending on the water flow rate through the filter
• Variable arrangement
• Filter cloth density
• Filter cloth material
• Sludge discharge ensured by gravity or by a pump
✓ Seasonal water demand surges exceeding system capacity
✓ Planned outages due to maintenance, upgrades, or replacement of the existing system
Wide range of technologies:
• Lamella settling
• Sand bed/drum filtration
• MF/UF
• Desalination/RO
• Ion exchange
• Evaporation and crystallization

High Performance Deodorization
deodorization by photoionization is the result of combining UV radiation, to different
wavelengths, with different types of catalysts for the generation of strongly oxidizing radicals. Requires no chemicals, sensors or
dosing systems.
Unlike chemical deodorization, which focuses on the reduction of certain chemical substances, photoionization always reduces the total odor, guaranteeing
the concentration of odors at the exit.
It is an ON–OFF switch technology. Easy to handle, robust and very reliable. Furthermore, the demand for maintenance
of Photoionization is considerably low. The technology does not require frequent attention from plant personnel.
More than 400 units installed around the world.
Neutralox technology is based on physical-chemical treatment methods. These treatment methods are characterized by the physical generation of oxidants, which
They are used directly or with the help of catalysts for the oxidation of odorous compounds and other pollutants.
The equipment is made of high quality stainless steel, of modular construction and is delivered as compact pre-assembled units.
The space required is small and the energy demand is considerably low.
They are also applied in industries that, due to processing requirements, cause odor problems in the environment or neighborhood. Some examples are the
chemical industry, food industry, etc.
