Owing to its quality, water that comes straight from the raw water source can rarely be directly used for drinking or commercial and production/manufacturing operations. Treatment of effluent or process water provides an opportunity to recover this valuable resource for reuse within operations.

Our research and development centres all over the world are therefore working on developing innovative technologies and processes for treating drinking water, boiler and cooling water, manufacturing and production operations and effluent treatment.

Industrial Commercial

Industry Solutions

BWT will advise you, from the initial water analysis stage through to commissioning and maintenance of your water treatment plant, based on your specific needs. All of our processes are carried out with maximum efficiency and implement all the legal, technical and commercial safeguards.

BWT offers specific solutions for a wide variety of industries, regardless of the existing water quality and the needs the water ultimately has to satisfy:

Silky-Soft Pearl Water for All

Specifically to meet the growing demand for water in large residential complexes, BWT has developed Pearl 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 Pearl 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 Pearl Water.

Boiler Water

Specific guidelines and legal stipulations must be observed when planning treatment plants for steam and hot water boilers with flow temperatures of over 100 °C. It is a false economy for plant operators to try saving money on professional planning and design, as heat-​generating deposits and corrosion can lead to faults, high operating and repair costs, and even to a depreciation of the system.Treatment of the boiler water guarantees that the entire system will run smoothly and seamlessly, for which BWT provides an optimal set of 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. BWT also continuously monitors the costs of your energy, fresh water and wastewater.

Cooling & 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 (e.g. VDI in Germany, ÖNORM in Austria)

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.

Process Water

Rising energy prices and increasingly scarce resources require careful handling of our environment and new approaches to the pool sector. BWT is also committed to energy efficiency through its ‘Energy Solutions’. Customised energy solutions and state-​of-the-art products ensure that your swimming pool and your entire home automation systems function efficiently.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 Pearl 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.
