A final product of first class requires raw materials of high quality

The requirements put on the raw material brew water are individual. By selecting the best treatment procedure or procedure combination resp. we individually react to the master brewer’s suggestion. Cooling water and boiler feed water are subject to specific quality criteria. By choosing the best treatment operating costs for cooling and heating can be reduced. A majority of the water is used as cleaning water for bottle rinsing. By using the best water and modern recycling methods the fresh water quantity can be reduced significantly.

Typical procedurs for breweries:

• de-ironing
• de-manganising
• degassing
• filtration
• de-carbonisation
• ion-exchange
• reverse osmisis/ nano-filtration

Consulting

Water treatment plants are long-lasting investment goods. Before planning, plenty of factors have to be considered so as to reach a perfect and operationally-related conception. Quite frequently our entire know-how is in demand to reach the best result.

It does not always have to be a new and a larger plant. A review of existing systems is always worth doing.

Apart from a function check the following issues are also checked among other things.:

• What reserves does the existing plant offer?
• Is the used equipment (energy, chemicals, …) used ideally?
• Is the maximum of water quality achieved?
• In what way can the existing plant be optimized/expanded?

When signing a service contract we are able to offer some more fair conditions. We are also pleased to submit an offer for a service- or maintenance contract.

Planning

To find one’s way in the range of water- and waste water treatment not only requires a high degree of knowledge concerning the large variety of possibilities available but also the knowledge to continuously further develop existing processes and experiences. This is the only way to keep our high level of development and problem solving and to fulfil the continuously growing requirements.

ATN stands for maximum know-how and latest state of the art technologies as well as plants and procedures.

The water treatment techniques are as versatile as the raw water available.
Therefore a careful and in-depth study is indispensible already while consulting and planning. All information is considered and tailored to the individual basic conditions. This makes the planning customized.

Plant construction

Already in 1996 the company ATN made the transition from a single plant engineering office towards a plant construction firm. ATN offers integrated solutions for water treatment since twenty years now. The services include design, engineering, supply, installation and commissioning of turnkey systems as well as future service and maintenance activities.

Through agreements and strategic alliances with partner companies ATN can concentrate on his core competencies and deliver integrated solutions from a single source. The production of the ATN systems is carried out by carefully selected, long-standing partners. For the selection of our partner companies we set value on highest quality and clearly admit to manufacturing in Germany due to the associated values.

With planning, engineering and construction of standard and above all customized equipment and processes for the beverage, food and pharmaceutical industries as well as for breweries and horticultural businesses, the company has made a name in the field of economic water treatment in recent years.

Research & Development

Just one year after the foundation of the company Aqua Technologie Nörpel in 1992 the first patent was applied for.

Continuously growing demands for water conservation and waste water cut as well as maximum reduction of expenses require new technologies of highest level. A good example for further development of recycling systems are the two new plants ContiREC and ContiFIL. They allow a considerable water conservation especially with bottle rinsing machines.

The development of own and new technologies that are mostly patent protected, shape decisively the actions of the company.

We offer you the possibility to sign a service and maintenance contract. This contract includes a regular expert service of your systems and equipment. We should be pleased to submit an offer tailored to your particular needs.

Water of brilliant quality and purity

Mixing of fruit juice drinks, soft drinks and fruit juice requires a water of brilliant quality and purity. The water must assist the good taste of the drink and must not lead to reactions with the ingredients. Fruit acid for example must not be neutralised. Furthermore the microbiological purity of the water is an important criterion.

The treatment of natural mineral water must keep to the possibilities according to the mineral and table water regulations. The usage of suitable and modern filters allow us a specific and easy treatment of the high-grade raw material. In this process we concentrate on the classic ingredients such as iron, manganese and sulphur and increasingly on the trace substances arsenic, uranium, fluoride, radium, radioactivity etc.

Typical procedures in the range of non-alcoholic drinks and mineral water:

• de-ironising, de-manganasing
• filtration
• de-carbonisation
• on-exchange
• disinfection
• water recycling for cleaning water
• de-fluoridation
• desulphurization

We are sales partner of the companies Aquafine and Trojan UV.
The UV solutions of Trojan offer a cost-efficient disinfection. With unmatched scientific and technical expertise and a global network of specialists, representatives and technicians Trojan has proven to be the best choice for municipal UV solutions. The UV systems of Aquafine with its unparalleled performance, highest quality and the latest technology are addressed to a wide range of industrial companies.

UV-Disinfection of Drinking Water
Trojan technologies offers the world’s most modern UV-systems for the protection of drinking water
against microorganisms such as cryptosporidia and giardia. UV systems used in this field are certified
according to the current guidelines of DVGW (German Association of Gas and Water Experts).

UV-Treatment of Food
The food marketplace comprises several branches e.g. for mineral- and table water, food packaging,
plant watering, carbonated and non-carbonated beverages, dairy plants as well as meat and poultry
processing factories. UV technology is successfully used in the corresponding branches for the
control of pathogenic microorganisms.
UV-plants by Aquafine are also used for the disinfection of process water which is used as an
ingredient in food. Bottled drinking water and product water in concentrates, soft drinks, tea and
beer are commonly disinfected with 254 nm-UV-plants by Aquafine.

UV-Disinfection of Process Water
As this disinfection takes place in industrial fields the plant does not need a DVGW-certificate. Thus
there is a wider selection. The dosages of the plants are variable. Normally it is 300-400 J/m².

UV-Disinfection of Liquids

• Disinfection of liquids with very low transmission
• Diverse applications such as liquid sugar, juices, paints
• wide range of options
   

UV-disinfection of waste water
In order to meet the requirements of both public safety and environmental protection many water
companies have opted to use UV-disinfection as the most appropriate disinfection method compared
with chemical disinfection. The current bathing water directive is fulfilled.

UV-Oxidation Process – Degradation of Pollutant (AOP = advanced oxidation process)
Although both advanced oxidation processes and especially the combination of UV-treatment and
hydrogen peroxide have already been known since the 70s, these methods could not establish in
water treatment. Trojan, however, has recognised the potential of this technology at an early stage
and developed and optimised it in the last 10 years.
 

UV-Treatment in Microelectronics
The challenges in designing and constructing a water system for microelectronics are manifold.
The UV-systems by Aquafine comply with all existing specifications for ultrapure water which is to be
used in microelectronics. These include microbial disinfection, TOC reduction (total organic carbon),
ozone destruction and reduction of chlorine and chloramines. That is why numerous companies all
over the world trust in Aquafine UV-systems.
