Wastewater treatment plants

Wastewater should be taken care of not only for the preservation of clean nature. Discharge of untreated wastewater into the environment (other than into an underground wastewater treatment system) is a crime and punishable by law.

It’s therefore imperative that wastewater is properly treated and, ideally, reused/recycled for a variety of purposes that don’t require drinking water quality. Recycling/reuse of treated wastewater can significantly reduce the demand for drinking water by almost 50–60%.

A biological wastewater treatment plant is a type of wastewater treatment where biological processes are used to remove contaminants from wastewater. In such a treatment facility, microorganisms such as bacteria and fungi break down organic substances in the wastewater into less environmentally harmful compounds.

During this process, the goal is to:

a) Reduce environmental pollution;

b) Improve the quality of water discharged into rivers or other water bodies;

c) Prevent the spread of pathogenic microorganisms.

The wastewater treatment process consists of several stages aimed at removing contaminants from wastewater before releasing it into the environment. Here is a general description of a typical wastewater treatment process:

Wastewater collection: Wastewater networks convey wastewater to treatment facilities. Initially, the wastewater passes through a grit removal system, where larger contaminants such as debris or other sizable objects are eliminated.

Preliminary treatment: When wastewater reaches the wastewater treatment station, it undergoes mechanical cleaning, where contaminants such as finer particles and sand are removed. This stage is crucial for protecting subsequent treatment phases from an excessive amount of pollutants.

Biological treatment: The primary stage of purification where microorganisms are employed to break down organic substances in wastewater. Wastewater is held in tanks or reactors where microorganisms, typically bacteria, convert organic materials into simpler compounds, such as carbon dioxide and water.

Sedimentation of pollutants: After biological treatment, wastewater is directed to settling tanks where pollutants settle at the bottom, and clean water rises to the top. This helps separate pollutants from the water.

Chemical treatment: After wastewater leaves the sedimentation tanks, it can undergo chemical processing to remove remaining pollutants or neutralize harmful chemical compounds.

Disinfection: Before releasing wastewater into the environment, it can undergo disinfection using methods such as chlorination, ultraviolet radiation, or ozonation. This helps eliminate any remaining bacteria or other microorganisms that may persist after the treatment process.

Release into the environment: Ultimately, wastewater that has undergone all treatment stages is safely discharged into the environment, such as rivers. Importantly, before such discharge, the wastewater must be checked against local and international regulations to ensure environmental safety.

These stages of wastewater treatment aim to ensure that the wastewater is purified from harmful contaminants and complies with legal requirements. These are essential measures in ensuring public and environmental safety.

Biological wastewater treatment plants are characterized by various advantages, making them an effective and sustainable alternative for wastewater management compared to other treatment methods. These biological systems, utilizing microorganisms that naturally break down pollutants, possess several unique features that set them apart.

Environmental friendliness and sustainability: Biological wastewater treatment systems are environmentally friendly as they employ natural processes and require minimal energy or chemical usage. This helps avoid the generation of chemical waste and reduces the emission of greenhouse gases, contributing to sustainability.

Efficiency and flexibility: Microorganisms used in biological wastewater treatment systems are highly efficient in breaking down organic materials. This allows for the removal of a significant portion of pollutants present in the wastewater. Moreover, these wastewater plants can be adapted for both small-scale locations and large cities.

Longevity and reliability: Biological wastewater treatment plants can be long-lasting and reliable when properly maintained. They do not require frequent replacements or updates, allowing them to serve for an extended period.

All these advantages make biological wastewater treatment plants appealing and beneficial for the environment, society, and long-term sustainable wastewater management.

Micro-organisms are crucial for the functioning of biological wastewater treatment plants. This form of wastewater treatment is responsible for the most important part of the wastewater treatment process, as it promotes the natural breakdown and recycling of pollutants.

Biological wastewater treatment plants work on the biological principle. The plant contains an activated sludge, which is formed by micro-organisms. It’s activated by a blower blowing warm air, thus creating the perfect environment for the micro-organisms to multiply: they receive their “food,” i.e. the waste water, are supplied with oxygen (blower) and the whole volume circulates without standing still.

It also requires that the micro-organisms are healthy and active. Temperature, pH level, oxygen levels and other factors are essential for the micro-organisms to be able to perform their functions properly. The activity of these small organisms in a biological wastewater treatment plant is therefore an essential part of a successful and efficient wastewater treatment process.

Biological wastewater treatment plants are an efficient and sustainable way to discharge wastewater into the environment. But the question is: is this method suitable for all types of wastewater? The answer is a bit more complex and depends on many factors.

Biological wastewater treatment plants are often an excellent choice for residential wastewater. They can effectively remove organic matter and bacteria that are often found in residential wastewater.

However, the situation can be more complex in industrialised urban areas. Some industries may emit highly toxic substances or chemical compounds that are difficult to break down. In such cases, biological wastewater treatment plants may require an additional treatment step or special measures to effectively treat the wastewater.

However, it’s important to understand that modern biological wastewater treatment plants can be adapted to different types of wastewater. Equipment and technology are constantly evolving. Therefore, it’s often necessary to carry out more detailed studies and to consult specialists to determine whether a biological wastewater treatment plant is suitable for a specific application.

For these facilities to operate efficiently, they need to be continuously monitored, inspected and maintained to ensure proper wastewater treatment and minimum impact on the environment and human health. This is essential if a clean environment is to be maintained and if public welfare is to be ensured.

1. Automatic monitoring systems for large treatment plants: Most modern wastewater treatment systems are equipped with automatic monitoring systems. They continuously monitor parameters such as effluent velocity, effluent volume, pollutant concentration and other indicators. If these indicators are not within set limits, the system can send an alarm or even automatically adjust the treatment process accordingly.
2. Regular analyses and sampling: Analyses and sampling of wastewater treatment plants are carried out on a regular basis by public authorities and specialists. These analyses help to assess the performance of the system and to determine whether it meets the requirements. Sampling is carried out according to set schedules and includes tests for the presence of chemicals, bacteria and other pollutants in the wastewater.

Attention from maintainers and professionals: Wastewater treatment plants must be maintained by professionals. Specialists monitor the functioning of the plant, carry out the necessary cleaning and maintenance work and respond to faults. Proper maintenance and rapid response can prevent serious accidents and pollution.

Monitoring and maintenance of wastewater treatment plants is a periodic and long-term process that is essential to ensure environmental protection and the safe use of water sources.

Modern wastewater treatment plants are an important part of environmental protection, and many countries have specific rules, requirements and permits that regulate the use of these plants. Such regulations are necessary to ensure proper wastewater treatment, a clean environment and safety for human health. Thus, in answering the question, a number of important points can be highlighted.

Firstly, many countries have legislation or regulatory bodies that set rules and requirements for the use of wastewater treatment plants. These requirements often cover areas such as:

1. Quality standards: Wastewater treatment plants have to meet certain standards set for raw materials, components such as pipes, brackets, strength, weight, seams, storage conditions, even tools, etc.
2. Discharge limits: Set specific permissible amounts of pollutants that can be discharged into the environment. These limits may vary depending on local ecological conditions.
3. Permits: In most countries, special permits or prior approvals are required for wastewater treatment plants. These permits are usually granted according to the scale of the planned use, the technology and emission limits.
4. Technical specifications: Wastewater treatment plants must meet certain technical specifications and be properly designed and installed. This ensures their efficiency and safety.
5. Maintenance and support: The requirements include regular maintenance and support of the equipment to keep it functioning optimally.

It’s important to note that these requirements may vary from country to country or even region to region. It’s therefore important to familiarise yourself with the local legislation and to comply with the rules in order to install a wastewater treatment plant. This helps to ensure environmental protection and the correct operation of the wastewater treatment plant.

One of the key areas where we can make a positive difference is wastewater treatment and environmental protection. How can people contribute to better wastewater treatment and the well-being of our planet? Awareness is important, and we need to raise awareness about the environmental impact of wastewater treatment. Education can be a start: by familiarising ourselves with the stages of the process and its effectiveness, we can understand why sustainable wastewater treatment is important.

The use of the right chemicals must also be kept in mind. Chemicals used in households, such as cleaning products and pesticides, can reach the sewage system and the environment. Responsible use of chemicals can reduce the amount of pollutants in wastewater.

Another way to help protect the environment is to reduce water consumption at home and in the workplace, which also reduces the amount of wastewater that needs to be treated. When water use becomes smarter and more economical, the load on wastewater systems is reduced.

Better wastewater treatment and environmental protection is a common goal that we can achieve through our daily actions. Every step we take towards this goal helps to ensure a clean, healthy and sustainable environment for generations to come.

If wastewater is not treated properly, it can have serious consequences for both health and the environment. Improperly treated wastewater can lead to negative consequences that can affect public well-being and the ecological balance. Here are some of the possible consequences: 

Polluted water bodies: If untreated wastewater enters rivers, lakes or other water bodies, it can have harmful effects on aquatic ecosystems. Similarly, groundwater reservoirs can also be contaminated, which can lead to a reduction in freshwater resources.

Water pollution: Untreated wastewater can contribute to water pollution, with consequences including harmful effects on aquatic life. When water quality is reduced, this can have long-term effects on all the ecosystems involved.

Risk to human health: Harmful substances and pathogens in wastewater can cause outbreaks of disease in people who come into contact with contaminated water or harmful particles.

Contamination of the food chain: Wastewater in soil or crops can contaminate land and plants. This can lead to contamination of the food chain, where harmful substances are released into the food chain and subsequently into human bodies.

Impaired air quality: Untreated wastewater can release unpleasant odours and pathogens into the air, which can affect air quality and public health.

Environmental damage: Wastewater can damage the natural ecosystem. This can cause long-term ecological damage.

All these consequences illustrate why proper wastewater treatment is essential for public health and environmental protection. It helps preserve water and soil quality and contributes to a sustainable ecosystem.
