Application Area


Pure and ultrapure water

Water with drinking water quality is not good enough for many industrial applications. Depending on the requirements for water quality, appropriate treatment is required. For the highest quality requirements, such as in semiconductor or solar cell production, biotechnology and pharmaceutical production, ultrapure water, a water from which almost all ingredients have been removed, is required.

Weil Wasseraufbereitung has over 30 years of experience in the planning, production, installation and commissioning of pure and ultrapure water systems for various industrial sectors. This enables us to offer you an optimal and economical solution for your task.

The following processing methods are often used here (usually in combination of several methods):

 


Operating and process water

Especially for water-intensive production processes, it is usually economical for companies to pump their own well water and treat it if necessary. Depending on the analysis of the well water and the requirements of the process, we offer different treatment methods and plants. We have a solution not only for the usual disturbing ingredients, such as iron, manganese and excess carbonic acid, but also for more rare problems, such as arsenic, antimony, vanadium, nickel, boron, fluoride or organic substances.

We pay special attention to the possibility of reusing operating and process water. As a result, natural resources can be conserved and often operating costs can also be reduced.

Typical processing methods are:

 


Drinking water

The intensive use of groundwater by humans and the increasing dryness in some areas lead to a change in the water supply and water quality. At the same time, with increased knowledge due to new or more sensitive analysis methods and increased requirements for drinking water quality, increasingly more complex processes for drinking water treatment are becoming necessary, as they have been used for some time in the production of pure and ultrapure water.

This also includes reverse osmosis systems for the desalination of brackish groundwater or for the treatment of seawater.

 

 

In drinking water treatment, the following treatment methods are mainly used:

 


Industrial wastewater

Depending on the area of origin of industrial wastewater, these are contaminated with different ingredients and different requirements apply for indirect discharge into public sewers or for direct discharge into surface waters. By using various process techniques, the wastewater can be detoxified in a targeted manner (e.g. nitrite or chromate detoxification), neutralized and freed from heavy metals or other disturbing ingredients (e.g. oil-containing emulsions or hydrocarbons) and thus the discharge values can be undercut.

The reuse of wastewater for secondary applications is also becoming increasingly important. Through the use of membrane systems, such as micro- or ultrafiltration systems, the prerequisites for reuse can often be created.

Typical processes in wastewater treatment are:
