Soft Drink Industry

Water of brilliant quality and purity

Mixing fruit juice drinks, soft drinks, and fruit juices requires water of brilliant quality and purity. The water must serve as a backdrop for the delicious taste of the drink and must not interact with the ingredients. Fruit acid, for example, must not be neutralised. Furthermore the microbiological purity of the water is another important criteria.


Standardising products and production also requires a standardised starting point. Therefore, it is increasingly common to use desalinated product water that does not form any negative interactions with other elements of the final product. Reverse osmosis is used in the majority of cases. Modern plants are made entirely of stainless steel, so they can be cleaned and sanitised if necessary with hot water and no chemicals.

Typical procedures in the range of non-alcoholic drinks:

  • de-ironising, de-manganising
  • filtration
  • de-carbonisation
  • ion-exchange
  • reverse osmosis/nano filtration
  • disinfection
  • UV-radiation
  • water recycling for cleaning water

Breweries

A first class final product starts with high quality raw materials

Each brewery places different requirements on their brew brew water , which is an important raw material. We select the best treatment procedure or combination of preocedures to react to the master brewer’s suggestion.


Cooling water and boiler feed water are subject to specific quality criteria. By choosing the best treatment, we can help reduce operating costs for cooling and heating.


A majority of the water is used as cleaning water for bottle rinsing. By using the best water and modern recycling methods, we can significantly reduce the quantity of fresh water used.

Typical procedures for breweries:

  • de-ironising
  • de-manganising
  • filtration
  • de-carbonisation
  • ion-exchange
  • reverse osmosis/nano-filtration
  • UV-radiation

Mineral and table water

Natural mineral water must be treated in acccordance with mineral and table water regulations. Using suitable, modern filters allows us to easily treat high-grade raw material. This process concentrates on classic ingredients such as iron, manganese and sulphur and increasingly on the trace substances arsenic, uranium, fluoride, radium, radioactivity etc.


However, treatment with reliable processes is just one part of the challenge. Technical design and practical implementation are also important to make sure the water is not subject to unintentional or unauthorised changes.

One example of this challenge is the microbiological quality - which must not deteriorate through the entire conveying, treatment and storage area. It is essential to conserve the water's natural purity, or to ensure purity using appropriate measures.

Typical procedures in this field:

  • desulphurization
  • de-ironising, de-manganising
  • filtration
  • de-fluoridation
  • water recycling for cleaning water
  • UV-radiation
  • arsenic removal

Food industry

We build water treatment plants according to your individual ideas. All potential water consumers are considered, from product water to water for the CIP plant.


Water is used in almost all fields of the food industry.

From rinsing raw water to the finished product. As component of food, especially, water is subject to special requirements for chemical purity, mineralisation and of course its hygiene. No matter whether the water comes from a public drinking water supply or from a well, in most cases it must be cleaned or treated. The final product determines the water quality. You have the raw water - and we have the expertise and the technology to guarantee the quality you need. Only by carefully and thoroughly analysising the initial situation can we provide competent and target-oriented consulting services.

Typical procedures in the food industry:

  • de-ironising, de-manganising
  • filtration
  • decarbonisation
  • ion exchange
  • reverse osmosis/nano-filtration
  • disinfection
  • UV-radiation
  • water recovery
  • filtration of rinsing solutions
  • ultrafiltration

Pharmaceutical industry

Ultrapure water for the pharmaceutical industry.

As in other industries, water is required for the product itself, but also for cleaning equipment and piping. Requirements are very high in both cases. Whether the goal is Purified Water (PW) or Highly Purified Water (HPW) water treatment is always built around one or more membrane stages.


Other components are pretreatment, storage, and distribution. An individual needs analysis can help determine whether all components are thermally sanitized, or whether the proven combination of ozone/UV during storage and distribution is more appropriate.

Typical procedures in the pharmaceutical industry:

  • filtration
  • decarbonisation
  • ion exchange
  • reverse osmosis
  • electrodialysis
  • UV-radiation
  • ozonation
  • thermic sanitization

Horticulture

Irrigation water almost sterile and free of particles

Our procedure allows for EC-value adjustment and guarantees nearly sterile irrigation water free of particles. In addition, modern UV systems can be used to suppress algael growth .


Many companies are no longer able to use of pre-filtered surface water or rainwater. The reasons are complex:


  • increasing demands put on the hygienic quality of the water
  • better filtration for a trouble-free operation of the droppers
  • influence of the EC-value
  • growing discomfort with chemical disinfection

Typical procedures in the field of horticulture:

  • de-ironising, demanganising
  • flocculation
  • filtration
  • decarbonisation
  • ion exchange
  • UV-radiation
  • reverse osmosis/nano filtration
  • disinfection
