Waterguide for water treatment
Technical knowledge and expertise from our engineers
We have compiled explanations and definitions of the most important terms in water treatment. In our Waterguide, we have divided these explanations into categories; you can then use these to narrow down topics. Or simply use the technical term search and you will find what you are looking for. If you still have questions, please do not hesitate to contact us!
Aqua purificata
Aqua purificata is water that has been freed from impurities in order to make it usable for pharmaceutical or laboratory applications.
Brackish water
Brackish water is a mixture of seawater and fresh water, with a salt concentration of up to 5,000 mg/l, and is mainly found in coastal regions.
Cooling water
Waste heat power from plants, industrial and commercial production sites must be dissipated, which means a cooling circuit is required.
Dialysis media supply - connection system without dead zones
Conventional systems use branch lines to supply water to the dialysis machine. When the dialysis machine is not in use, the water in these dead-end branches remains stagnant at room temperature. The risk of germ multiplication increases with the time the system is not in use.

Drinking water
The German Drinking Water Ordinance (TrinkwV) defines “drinking water” as water that occurs in nature or has been treated (tap water) for the purpose of drinking, cooking or other domestic uses.
Pharmaceutical water
Pharmaceutical water, which is produced specifically for pharmaceutical purposes, must fulfil strict quality standards. The microbiological purity of the water is important to ensure the safety of medicines.
Processwater
In many production processes, water is used as a product or as a resource. Thus, process water is the water that is used in industry, in manufacturing processes, in energy generation or comparable applications.
Rainwater
Rain is liquid precipitation from the atmosphere in droplet form and an essential part of the water cycle on Earth.
Seawater
Approximately 71% of the Earth’s surface consists of water, of which 97.4% is seawater and just 2.6% is fresh water. This means that the sea is the largest habitat on Earth.
Surface water
Surface water is water that is found directly on the surface of the Earth, is unbound and takes the form of streams, lakes or rivers, but also puddles.
Thermally sanitizable reverse osmosis
You can only maintain a consistently high water quality if you regularly disinfect the entire water circuit, including the reverse osmosis unit.
Ultrapure water
Many water processes have special requirements for water purity and water treatment equipment.
Water Reuse and ZLD
Water reuse and ZLD (Zero Liquid Discharge) enable the economical and sustainable use of water resources through the reuse of process water and the extensive recovery of water.
Well water
Well water is water that, as the name suggests, is obtained from a well and is formed by rainwater, lake water and river water that has seeped into the ground.
WFI (Water for Injection)
The abbreviation WFI refers to "Water for Injection" and describes a highly pure, sterile liquid that fulfils the requirements of pharmacopoeia monographs for injection purposes.
In our Waterguide you will find in-depth Information on all aspects of water treatment
Water treatment describes the process of removing contaminants and pollutants from water to make it safe and/or pure for industrial or medical applications. Water treatment can involve a combination of different physical, chemical and biological processes such as filtration, sedimentation, disinfection, reverse osmosis and activated carbon adsorption. The goal is to produce water of a certain quality necessary for subsequent processes.
Water treatment is important in industry for various reasons. For example for:
- Process water: In many industries, water is used as a raw material in various production processes. Here it is important that the water used meets certain quality requirements and is free of contamination.
- Or cooling water: Many industrial plants need cooling water to regulate the temperatures in machines and equipment. The cooling water must be free of impurities to ensure the proper functioning of the equipment. Water treatment ensures that the cooling water has the required quality.
In medicine, water purification can be used in several ways. For example, in the production process of medicines and medical devices, pure water is often needed to ensure that the products are free of contaminants.
The water treatment also plays an important role in dialysis treatment, in which the blood of patients with kidney failure is purified. Thereby, the water must be extremely pure in order to prevent impurities from entering the patient's body. In addition, water treatment is also important in the process of cleaning and disinfecting medical equipment and instruments to ensure that they are free of germs and other harmful contaminants.
Water treatment in medicine is an important process that helps to ensure the safety and effectiveness of medical products and procedures. The water treatment units have special features of their own: They have an almost dead-zone free design with a high stainless steel content.
