Water is not simply water

Industrial & municipal water treatment

In order to make the most important foodstuff available worldwide, processes for the production of drinking water are required. Whether from surface water, well water or sea water, you need a solution that is tailored to your needs. The global need for clean drinking water is constantly growing. According to the UN, 11% the world's population still has no access to safe drinking water. At the same time, the stocks of suitable water resources are decreasing. Climate change, industrialization and environmental problems pose new challenges for drinking water production and treatment.

Industrial and municipal water treatment

Water treatment plays a crucial role in ensuring water supply and protecting the health of people and the environment. Effective water treatment processes are of great importance on both an industrial and municipal level in order to ensure clean and safe drinking water and to make industrial processes sustainable. In this paper, we will take an in-depth look at aspects of industrial and municipal water treatment, highlighting their goals, processes, and challenges.

I. Industrial water treatment:
Industrial water treatment refers to the process of cleaning and treating water used in industrial facilities. Industries often have specific water quality requirements, depending on the materials used, production processes and environmental regulations. The goals of industrial water treatment include removing contaminants, maintaining water quality, preventing corrosion and scale in equipment, and minimizing water consumption.

Industrial water treatment processes include:

1. Mechanical filtration: The use of filters removes particles and solids from the water. This can be achieved with sand filters, activated carbon filters or membrane filters.

2. Chemical Treatment: Chemicals such as flocculants and disinfectants are added to bind and remove suspended solids and kill potentially harmful microorganisms.

3. Reverse Osmosis: This process uses a semi-permeable membrane to remove dissolved salts, minerals and other contaminants from the water. It is often used to desalinate seawater or to treat process water in certain industries.

4. Ion exchange: In this process, unwanted ions in the water are exchanged for other ions, which can remove impurities such as heavy metals.

II. Municipal water treatment:
Municipal water treatment includes the process of treating drinking water for the supply of homes, offices, schools and other public facilities. The goal is to provide water of high quality that meets applicable drinking water standards and guidelines. Municipal water treatment typically involves a number of steps to treat the raw water from natural sources such as rivers, lakes or groundwater.

Municipal water treatment processes involve similar steps to industrial water treatment, but with an emphasis on removing potential

harmful microorganisms to ensure drinking water safety. Typical steps include:

1. Graining and Flocculation: The addition of flocculants brings particles and impurities in the water together to form larger flocs that are easier to remove.

2. Sedimentation: The flocs settle to the bottom of a basin, forming sludge that is removed.

3. Filtration: The water is passed through various filter layers, such as sand, gravel and activated carbon, to remove finer particles.

4. Disinfection: The treated water is treated with disinfectants such as chlorine to kill pathogens and ensure microbiological safety.

Challenges and future developments:
Both industrial and municipal water treatment face challenges such as increasing water consumption, scarcity of water resources, increasing pollution levels and the impacts of climate change. Meeting these challenges requires innovative technologies and sustainable approaches.

Future developments could include:

1. Water reuse: Implementing wastewater treatment and reuse systems can reduce water consumption and improve sustainability.

2. Advanced disinfection technologies: New methods of disinfection, such as UV irradiation or advanced oxidation processes, can effectively kill microorganisms while reducing the use of chemicals.

3. Adaptation to climate change: Water treatment plants must be prepared for the impacts of climate change, such as changing precipitation patterns and increased water stress situations.

Industrial and municipal water treatment are essential processes to provide clean and safe water for human consumption and industrial purposes. They include a variety of processes to remove contaminants and improve water quality. In view of the increasing challenges related to water resources and environmental pressures, continuous development and adaptation of water treatment technologies is of great importance to ensure sustainable water supply and protection of the environment.
