Biological Wastewater Treatment

Biological wastewater treatment is one of the most effective ways to treat liquid waste. This method is based on the use of microorganisms to oxidize and mineralize organic matter in wastewater.

The biological treatment process takes place in special bioreactors, where microorganisms feed on organic substances released from wastewater. In the process of their life, microorganisms oxidize and mineralize organic substances, converting them into water and carbon dioxide.

Biological wastewater treatment has a number of advantages over other treatment methods. First, it is more effective at removing organic matter from wastewater, which reduces the load on wastewater treatment plants and reduces the amount of pollutants released into the environment. Secondly, the microorganisms involved in the biological treatment process are environmentally friendly and do not harm the environment.

However, for bioreactors to operate efficiently, it is necessary to ensure sufficient access of oxygen and nutrients for microorganisms. It is also necessary to monitor the quality of wastewater and ensure that it does not contain too much organic matter, which can slow down the biological treatment process.

In general, biological wastewater treatment is an effective and environmentally friendly method of treating liquid waste, which can be used in various industries and in everyday life.

Biological wastewater treatment is a process that removes organic matter from a liquid using microorganisms. This purification method is one of the most effective and environmentally friendly ways to remove contaminants from water, and is used in many industries and in everyday life.

Biological treatment occurs due to the presence of specific bacteria in water, called “aerobic”, which are able to use oxygen to oxidize organic contaminants. Aerobic bacteria live in water in the form of biofilms that cover the surface of solid particles such as sand and clay. These biofilms provide habitat for aerobic bacteria, which in turn oxidize organic matter, converting it into carbon dioxide and water.

The biological treatment process includes several stages:

1. Primary purification: In this stage, the water passes through an activated carbon filter, which removes inorganic contaminants such as metals and salts from the water.

2. Aerobic treatment: At this stage, aerobic bacteria are added to the water and begin to oxidize organic contaminants.

3. Filtration: After the aerobic purification process is completed, the water passes through filters that remove remaining organic contaminants and other impurities.

Advantages of biological treatment:

– Biological treatment is an environmentally friendly method of removing contaminants, as it does not require the use of chemical reagents.
– This method removes organic contaminants such as fats, proteins and carbohydrates, making it effective for wastewater treatment.
– Biological treatment can be used to treat industrial wastewater, as well as for domestic needs.
– This method allows you to reduce the amount of waste generated during wastewater treatment.
