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!
Activated carbon Filtrasorb 300
The activated carbon Filtrasorb 300 is a highly effective granulate activated carbon, which is used in water treatment to remove taste-producing and odorous substances, as well as dissolved organic compounds.
AFM® NG
AFM® NG has a unique hydrophobic surface for the advanced adsorption of organics and microplastics. It is an inert and amorphous aluminium silicate (glass)..
An Overview of our filter media
Here you can gain an overview of the application areas of our filter media.
Anthracite N
Anthracite N is one of the filter materials that is found in nature. It is extracted from the sea at a depth of around 1500 m and then cleaned, crushed and sieved to removed unwanted foreign particles.
Aqua purificata
Aqua purificata is water that has been freed from impurities in order to make it usable for pharmaceutical or laboratory applications.
Birm
This filter medium is an aluminium silicate that is coated with manganese dioxide. No chemicals are used for regeneration and water is sufficient for backwashing.
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.
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.
Filtration
In the case of water content, a distinction is made between solid particles and dissolved substances. Solid particles such as suspended solids and granular particles are almost completely removed by filtration if the particle size and density are high enough.
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.
Sand and silex
Sand (silica) is the oldest filter material found in nature due to its many different forms (sand, silex, gravel).
SDI
SDI is short for silt density index. It is used to express the amount of particles in the water. It is also used to predict the fouling tendency of a membrane.
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.
Turbidex
Turbidex consists solely of the mineral aluminosilicate (zeolites) and has remarkable sediment filtration properties.
Ultrafiltration
Ultrafiltration is a filtration process from the field of membrane technology that can be used to separate and concentrate macromolecular substances and small particles from a medium.
Ultrapure water
Many water processes have special requirements for water purity and water treatment equipment.
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.
