Here you will find an overview of the most important points to consider when purchasing water purification plants:

The professional purchase of water purification plants is a strategically significant decision that goes far beyond the acquisition costs. Water purification plants are technically complex, must meet specific quality requirements and are subject to strict legal regulations depending on their intended use. Errors in selection can lead to inadequate water quality, process disruptions, increased operating costs or legal problems. It is therefore crucial to design the procurement process systematically and on the basis of technical, economic and operational criteria.

• At the outset, it should be precisely defined which water is to be treated and what it is to be used for.
• Parameters such as hardness, conductivity, particle content, chemical composition, microbiological contamination and possible pollutants play a central role here.
• The requirements differ considerably depending on whether the water is used for drinking water, industrial processes, cooling circuits or food production.
• A precise water analysis forms the basis for selecting the right technology.
• When purchasing, the quality of the purified water must be clearly defined.
• This includes compliance with legal requirements, e.g. drinking water regulations or industrial process standards, as well as internal requirements such as hardness, conductivity or sterility.
