Wastewater treatment technologies for sustainable urban development

Currently, wastewater treatment technologies play an important role in the sustainable development of cities, striving to provide a clean and environmentally safe environment for all residents. Wastewater treatment is an integral part of urban infrastructure, helping to eliminate pollution and minimize the negative impact on the environment.

One of the key directions in the field of wastewater treatment is the use of environmentally friendly methods without chlorine. Such methods include ozonation of water, disinfection with sodium ferrate and plasma disinfection. They make it possible to effectively clean wastewater from harmful microorganisms and pollutants without the use of chemicals, which contributes to the conservation of natural resources and the prevention of environmental pollution.

Another important technology is the wastewater reuse system. It allows the purified water after the treatment process to be used for various purposes, such as watering plants, irrigation, industrial needs and others. This reduces the need for fresh water and contributes to more efficient use of resources.

Integrated water purification systems, including the use of membranes, highly selective adsorbents and biological purification, ensure the effective removal of various pollutants, including organic compounds and heavy metals. Such systems are widely used both in small towns and in industrial complexes where a high degree of wastewater treatment is required.

Wastewater treatment technologies based on algae and microalgae are a promising direction of development. These plants are able to absorb and convert harmful substances into safe compounds, which makes them effective in combating pollution of reservoirs and wastewater. The use of algae in the purification process helps not only to remove pollution, but also to restore ecological balance in aquatic ecosystems.

Another innovative technology is nanobubbles used for wastewater treatment. Nanobubbles of air are introduced into the water, forming microscopic bubbles that actively interact with pollutants and contribute to their removal. This is an effective and environmentally friendly method that allows to achieve a high degree of wastewater treatment.

Purification of industrial wastewater from oils, oil and heavy metals is one of the key tasks. Innovative methods such as activated charcoal based on rice husk, which has a high adsorption capacity to pollutants, are widely used in this field. Special processes of disinfection of wastewater by plasma jet are also used to ensure the effective elimination of dangerous microorganisms and viruses.

Wastewater treatment technologies play an important role in maintaining a clean and healthy environment. They contribute to the sustainable development of cities, minimize the negative impact of industry on the environment and provide access to clean drinking water. The introduction of modern and environmentally friendly wastewater treatment technologies is an important step in creating a sustainable and favorable environment for the life and development of the city.
