General information about water hygiene

Disinfection solutions are as specific as your industry and your requirements. And that's what makes it so much fun: I like to master challenging tasks because it allows me to bring my innovative systems and many years of engineering experience to bear. The focus is on efficient disinfection with less use of chemicals. This protects the environment, man and machine. And quite incidentally, the operating costs are also reduced. ProMinent offers all methods of disinfection (chlorine dioxide, chlorine gas, ozone, UV light, electrolysis, ECA water and ultrafiltration) and effortlessly combines several disinfection technologies. Not only drinking water is thoroughly cleaned, but also cooling water, swimming pool water and also service and product water in industrial applications. By the way, since our modern disinfection solutions are always intelligent, we call our water treatment Smart Disinfection.

The large number of hygienically relevant microorganisms that are present in the wastewater even after biological treatment requires adequate treatment of the wastewater before it is discharged into sensitive surface waters and in particular before water is reused. The inactivation of pathogenic microorganisms through wastewater disinfection is a crucial process to protect against waterborne diseases. The aim of the project was to examine various wastewater disinfection processes from the point of view of hygiene, economy and ecology, also with regard to possible water reuse, using test facilities operated in Germany and China. In addition to the dosing of chlorine gas produced on-site, the dosing of chlorine dioxide, ozonation and UV radiation were selected as disinfection methods for the investigation. These different disinfection methods were operated and analyzed in parallel and under identical test conditions, so that a good comparability of the results achieved was ensured. Results: The examined disinfection processes produced a discharge which can also be safely discharged into sensitive surface water and is well suited for reuse purposes. The formation of various disinfection by-products could be detected in the processes of all processes, except for UV radiation. In the processes in which no or too low concentrations of residual disinfectants were detectable in the water, an increase in the number of colonies could be observed after the treated water had stagnated for 24 hours. A significant increase in the concentration of E. coli was not detected after any of the disinfection methods used. A simultaneous elimination of a broad spectrum of trace substances during the wastewater disinfection could only be achieved with ozone.

Disinfection (fumigation) Removal and/or killing of microorganisms, especially pathogens, by physical or chemical processes. Although the term "disinfection" is often equated with sterilization, disinfection is merely killing or inactivating pathogens of communicable diseases, but not all germs. Therefore, on closer inspection, disinfection is a selective sterilization. In the field of water treatment, for example, UV radiation and a strong reduction or increase in temperature can have a disinfecting effect (thermal disinfection). Chemical disinfectants are, for example, alcohol and various chlorine compounds. In some cases, membrane separation processes are also used. The wastewater disinfection of treated wastewater from sewage treatment plants is generally not practiced in northern Europe, whereas it is quite common in southern countries. Water disinfection is also necessary for swimming pool water, among other things. In properly operated swimming ponds, on the other hand, disinfection occurs through a natural balance.

Disinfection and sanitation of water: A comprehensive look

The disinfection and hygiene of water are essential to ensure the health and well-being of people. Clean and hygienic water is a fundamental commodity that is essential for human consumption, agricultural use and many industrial processes. In this paper we will examine the different methods of water treatment and disinfection and their importance for public health.

1. The Importance of Water Treatment:
Water treatment aims to remove contaminants and make the water safe for human consumption. Untreated water can contain pathogens such as bacteria, viruses, parasites, and chemical contaminants that can cause serious illness. Proper water treatment can reduce or eliminate these potentially dangerous contaminants.

2. Methods of water treatment:
a) Filtration: Filtration is an important first step in water treatment. Solids, sediments and larger particles can be removed by using filters. This helps to reduce the turbidity of the water and make the subsequent disinfection process more effective.

b) Chemical disinfection: Chemical disinfection is a common method to kill pathogens in the water. Chlorine, chloramines and ozone are commonly used disinfectants. These chemicals can effectively kill bacteria, viruses, and other microorganisms, making the water safe for human consumption.

c) UV irradiation: UV irradiation is a non-chemical method for disinfecting water. By exposing the water to UV light, microorganisms are inactivated and their ability to reproduce is suppressed. UV radiation is well suited for disinfecting small amounts of water and can be an effective complement to chemical disinfection.

3. Hygiene of water:
In addition to disinfection, maintaining proper water hygiene is of great importance. This includes measures such as preventing cross-contamination, protecting water reservoirs from pollution and promoting conscious water use. Regular inspections of water supply systems, proper maintenance and compliance with hygiene guidelines are crucial to ensure a safe water supply.

4. Challenges and future developments:
Despite advances in water treatment and disinfection, there are still challenges to overcome. The rising Bel

Depletion of water resources, especially in densely populated areas, climate change and new types of pollutants are creating new demands on water hygiene. Therefore, continuous research and development of improved disinfection methods and the implementation of efficient monitoring systems are of great importance.

Water disinfection and sanitation are vital to ensure clean and safe water is available for human consumption. The combination of effective water treatment, disinfection techniques and maintaining proper water hygiene is key to preventing disease outbreaks and protecting public health. It is important that governments, organizations and individuals work together to improve the quality and availability of clean water around the world.
