We at WM aquatec would like to offer you “tailor-made” solutions. By “tailor-made” we mean technical solutions that enable you to obtain water of the desired quality for your application – regardless of whether you are an enthusiastic camper, an outdoor enthusiast, a proud boat owner or a successful entrepreneur. In order to be able to guarantee this, we keep our eyes and ears open – at trade fairs, when talking to customers on the phone or when visiting you on site. We are always grateful for your suggestions and constructive criticism and open to continuously improving not only our products but also ourselves. According to your needs, the demand on the market or our feeling for innovative and practical products, we will then act and present our solutions to you.
Drinking water is/must be provided by the public waterworks/water suppliers in a quality that prevents damage to human health, especially through pathogens, through its consumption or use. Nevertheless, under unfavorable conditions in drinking water systems, pathogenic microorganisms such as legionella multiply, which can pose a major risk to human health. In drinking water systems, the pathogens then embed themselves in a so-called biofilm, which serves as a source of food and protects you from external influences. This leads to the continuous growth of the biofilm and to the further multiplication of the pathogens.
With process water in industrial plants, especially in the manufacture of products, there are increased demands on the water quality and thus also on the water treatment. Whether cooling water, boiler feed water or ultrapure water, here too we set standards with our hygiene products.
Microorganisms in the cooling water can lead to health hazards, unpleasant odors and the formation of a biofilm. Therefore we offer you products to comply with the hygienic requirements according to VDI 2047 (ensuring the hygienic operation of evaporative cooling systems).
Depending on the application, fluid (water) carrying systems must be cleaned at regular intervals. If cleaning processes (mechanical/chemical) cannot produce a microbiological quality that meets the requirements, disinfection measures can promise success. As an example, reference is made to the DVGW worksheet W 291 “Cleaning and disinfection of water distribution systems”.
Filters are used above all in industrial water treatment, but also where certain parameters of the water/fluid have to be maintained or changed. In comparison to line systems, filters usually offer a larger volume in relation to the volume flow, so that the flow velocities are lower here. These in turn and other factors can contribute to the fact that filters and their elements become contaminated over time and microorganisms settle. This can be countered either by continuously adding disinfectants/preservatives or by discontinuous filter disinfection.
In buildings such as hospitals, clinics, retirement homes, government and administrative buildings, stables, animal rearing facilities, greenhouses or production facilities, the air is usually treated by ventilation and air conditioning systems (heating, cooling, humidification and dehumidification, etc.).
In order to comply with the hygiene requirements for room air, it is necessary to take hygienic measures that minimize or prevent the exceeding of limit values in the air and contamination of the system components. VDI 6022 “Indoor air quality and hygiene requirements for indoor air in buildings” provides state-of-the-art recommendations.
Numerous fire extinguishing systems in buildings (e.g. sprinkler systems, wall hydrant systems) are constantly filled with water and directly (directly) connected to the drinking water installation. A stagnation of the extinguishing water can lead to an increase in microorganisms, whereby the risk of the drinking water being impaired also exists when installing pipe separators. […] Due to the stagnation of the water in the fire extinguishing mains, which has sometimes lasted for decades, there can be considerable, especially microbiological, impairment of the drinking water if the stagnant water flows back into the drinking water installation. ¹

The elimination/oxidation of odors can be achieved with the nebulization of chlorine dioxide can be achieved. By finely dividing the chlorine dioxide mixture using a nebulization system, odors are eliminated within a short period of time with a minimum of work.
Emergency showers in industry are constantly in contact with the available water in the pipes and are either equipped with tanks (mobile emergency showers) or connected directly to the drinking water installation. The stagnation of the shower water can lead to an increase in microorganisms and thus pathogens such as legionella in the storage tank (mobile emergency shower) and in the pipework, whereby there is a risk of contamination of the shower water and the connected drinking water even if pipe separators are installed. A long stagnation time of the water can lead to significant, especially microbiological, contamination of the drinking water, for example if the stagnant water flows back into the drinking water installation.
Substances that cause odors in exhaust air systems are mostly caused by volatile nitrogen or sulfur compounds. These can be successfully broken down by oxidation. The dosing of chlorine dioxide into the exhaust air scrubber or through its entry using a nebulization system is suitable here.
Swimming pool and pool water are exposed to constant contamination. Above all, the introduction of germs by humans (faecal germs), but also the introduction of germs through the air as well as growing germs and pathogens in the swimming pool/pool technology (pipes, lines, filters, pool walls and floors) ensure a continuous deterioration in the water quality. In order to be able to guarantee hygienic bathing pleasure, the Infection Protection Act (IfSG of July 20, 2000, last change on July 18, 2016) states in § 37 para. 2: “Swimming or bathing pool water in commercial establishments, public pools and other facilities that are not exclusively used for private purposes must be of such a quality that its use does not cause any damage to human health, in particular through pathogens.”
In apparatus and plant construction, we are a competent partner when it comes to the hygiene of water depots, pipes or other components. Whether special systems or series devices, fluid-carrying systems for home applications (e.g. mobile air humidifiers) or medical equipment such as water-cooled sterilizers – together we will find your solution.
Most diseases in pond fish or in fish farming result from deficits in husbandry. This is often due to poor water quality. A healthy balance of bioavailable nutrients and bacterial colonies are important here. If these get out of balance, pathogens such as bacteria from the Aeromonas and Pseudomonas groups can suddenly multiply and trigger mouth or fin rot, for example.
Thanks to our chlorine dioxide products, the cleaning and disinfection of food technology systems (tanks, lines, etc.) can be carried out in one operation. The disinfection takes place during the acidic cleaning of the CIP cleaning, whereby the chlorine dioxide is gradually and completely broken down into chloride (common salt). A final rinse with, for example, ultrapure water ends the CIP process.
Clean and low-germ drinking water is the basis for economical and successful cattle breeding. Heavily contaminated drinking water and biofilm growth in the pipe system carrying drinking water and the associated, uncontrolled proliferation of pathogens pose a great danger to all livestock. Air or surface disinfection is also an important measure for restoring hygiene standards in the case of diseases that have already occurred.
Dispensing systems, water dispensers or coffee machines are subject to special hygienic regulations due to the provision of food. These are regulated in European ordinances and examined in detail in the standards system in relation to the industry and application. As an example, the “DIN 6650-6 – Beverage dispensing systems – Part 6: Requirements for cleaning and disinfection 2014-12” is mentioned, which deals in particular with hygiene, disinfection of the system, maintenance intervals, etc. for dispensing systems.
