The highest standards of hygiene safety in drinking and industrial water systems and in purified water for industrial processes
Owing to its composition and quality, water that comes straight from the tap can rarely be used for commercial operations, healthcare, the public sector or building technology, and the quality standards required for the water supplied vary depending on the industry. BWT’s aim is to deliver the best water quality for every application.
Our research and development centres all over the world are therefore working on developing innovative technologies and processes for treating drinking and boiler water, water for cooling and air-conditioning, heating water as well as purified and process water.

Drinking Water
Water and its composition vary according to the region, the settlement and the geological nature of the terrain. Some regions have pure water, others have water rich in calcium or iron, and in some places the water is contaminated with pollutants. Climate change and a growing population mean that, in many parts of the world, the local water is not even safe to drink without being treated first, which makes it a top priority to adopt a responsible approach to this increasingly precious resource.
BWT is dedicated to the purification of this precious consumable, water, for which it has developed pioneering technologies and processes, whether for treating well or spring water, supplying drinking water in cities and communities or for construction technology. Various methods are used to filter particles and calcium from the water to protect the pipe systems against the build-up of deposits and calcium. A comprehensive hygiene management system has been designed to prevent and eliminate Legionella and other bacteria.
Silky-soft Luxury Water for all
Specifically to meet the growing demand for water in large residential complexes, BWT has developed Luxury Water systems for turning hard, calcareous water into soft water with a low calcium content. Water that is too hard leaves unsightly deposits on fittings, tiles and glass, and can also lead to a build-up of limescale in the pipework or equipment and ultimately to costly repairs.
BWT’s Luxury Water systems are also guaranteed to operate hygienically, efficiently and economically with a minimal use of resources, so that all those living in residential blocks can enjoy the benefits of silky-soft BWT Luxury Water.
Boiler Water
Providing the right water for the safe and reliable operation of boilers require a high level of expertise and first class products. When planning treatment plants for steam and hot water boilers with flow temperatures of over 100 °C specific guidelines and legal stipulations must be observed. It is a false economy for plant operators to try and save money on a cheap or poorly specified water treatment solution. As heat-generating deposits and corrosion can lead to faults, high operating and repair costs, and even to a failure of the system. The right treatment of the boiler water guarantees that the entire system will run smoothly and seamlessly. BWT will not only specify the right products but can also provide an optimal set of operating procedures. These, of course, include adherence to all the legal requirements, operating regulations, the boiler manufacturer’s specifications, the properties of the raw water and all the standards applicable to water quality.
Cooling and Air-conditioning Water
Cooling water
Systems with a closed cooling water circuit often contain plastic pipes, in which case a single filling with softened or demineralised water is sufficient.With open re-cooling systems however, i.e. all systems with cooling towers, water treatment is almost always necessary. Since only pure water evaporates, the concentration of minerals in the circulating water is constantly rising, and excessive salinity results in calcium deposits and corrosion in the cooling tower and water pipes. Algae and dust particles may also block nozzles, valves and cooling channels. BWT’s first-class cooling water treatment contributes to the economical and uninterrupted operation of the cooling tower.
Air-conditioning water
Many modern residential blocks are equipped with humidifiers, and the health and wellbeing of the residents may be significantly impaired if the air humidification is insufficient or ineffective. Hygiene considerations play an especially key role in the planning and operation of humidifiers.Various methods are used to humidify the air and, depending on the system installed, BWT modifies the method of treatment for the humidification water. Reverse osmosis systems, for example, are often used to desalinate drinking water, and this process can be supplemented with disinfection systems. The use of demineralised water can reduce the formation of biological or calcium deposits.
Heating Water
A heating system consists of many individual components: boilers, buffer tanks, pumps, control valves, etc., and the various parts must work together seamlessly to ensure efficient, reliable operation. A decisive factor in the efficiency of a heating system is correct treatment of the heating water that comes into contact with most of the components.
Many manufacturers of heating system components are now also stipulating in their warranty conditions and operating instructions that users comply with the legal standards and regulations that regulate the precise quality of the heating water.
Operational safety with the correct water
Specific substances in the water can cause problems in the heating system. Deposits like limescale may, for example, affect heat distribution, and a coating just 1 mm thick increases the energy requirement by 10%. In addition, an incorrect pH value, an excessive injection of oxygen or organic contamination may result in corrosion and blockage of individual components in the heater. Only correctly treated heating water will therefore guarantee energy-efficient operation of the heating system and protect it against damage.Natural heating water with no chemical additives
Designers and installers of heating systems should err on the side of caution and rely on the natural heating water of BWT, which is free of chemical additives. Low-salt, calcium-free water reduces substances in the water that cause deposits and, with the correct mineral level, the pH value regulates itself naturally after several weeks*.
BWT therefore supplies safe heating water that complies with the relevant standards, and our range of filtration, cleaning, flushing, ventilation, de-gassing and de-sludging products ensures that your heating system operates with maximum efficiency.
*Always refer to local regulations and manufacturers instruction as part of your water treatment selection process. Our fully trained staff are often local water experts and will be happy to help
Process Water
Water is used for numerous processes in the technology sector, and the choice of treatment technology depends on the quality of the water on site. BWT has many years of experience in a wide range of applications: laboratory and rinsing water, wood-drying systems and the production of mineral water and also test water, which is used, for example, to carry out standardised tests on washing machines.
Water low in minerals is often required, e.g. for rinsing glassware, cleaning sensitive surfaces, for use in laboratory rinsing machines and to operate cleaning and disinfection equipment. If the mineral content in the water is too high, limescale deposits will form on crockery and technical appliances.
Purified Water
Technically pure water, i.e. purified water, is indispensable for the pharmaceutical industry, for laboratories and for a wide variety of industrial production processes. Unlike drinking water, purified water is totally free of additives, including minerals, calcium and other impurities.
Purified water is not suitable to drink, but is a key component in the production process for medicines, microelectronics, glass and beverages. Purified water of consistently high quality is used for cleaning and rinsing, particularly in laboratories, and also as a solvent and carrier medium. BWT supplies the right treatment solution for every requirement of BWT Purified Water, depending on the specific application.
Sea Water Treatment
Only a tiny percentage of the world’s water reserves, just under 1%, can be used as drinking water for humans, and this is further complicated in some regions by an inadequate, or total lack of, access to a supply of clean drinking water. BWT has developed seawater desalination processes that turn salt water into precious drinking water.
An independent, secure water supply is essential, even for companies in regions with a poor infrastructure. Sea water is playing an increasingly important role in tourism, for example, because only a fully-functioning, reliable water supply will ensure that guests can enjoy a relaxing holiday, with access to clean drinking water and silky-soft Luxury Water in the pool and spa.
Efficient BWT sea water desalination for perfect drinking water
BWT has many years’ experience in sea water desalination. Not only do we guarantee low operating costs, but we can also reduce energy consumption using integrated energy-recovery systems.
Our objectives are to produce drinking water of the highest quality, to use our increasingly scarce water resources in a sustainable way and to make a real contribution to the protection of our environment.
