There has been a growing concern about environmental pollution. It is the adverse effects of releasing untreated wastewater into rivers and other natural water bodies. Strict regulations worldwide ensure proper sewage treatment. It safeguards the environment and the public health. Sewage water treatments plants help treat wastewater before releasing it into the atmosphere. In this critical situation, a reliable sewage treatment plant supplier can help you manage wastewater effectively. Different technologies are available. This blog will offer you a knowledgeable perspective on the various types of sewage treatment plants available.
Stages in Sewage Water Treatment
Sewage treatment facilities generally follow several stages to remove contaminants before water discharging. Stages may differ on the type of sewage water treatment:
- Primary Treatment
The first and primary stage involves a large chamber where wastewater flows. Heavy sediments settle at the bottom. The oil and grease that float to the top can be skimmed off. The wastewater leaving the chamber is referred to as effluent.
- Secondary Treatment
The secondary treatment removes organic matter and pollutants from the wastewater. Microorganisms convert pollutants into cell tissue, water, and nitrogen. Aeration and activated sludge are key components of this process.
- Tertiary Treatment
The tertiary treatment removes more than 99% of impurities from the wastewater. It makes it suitable for discharge. This stage may use a combination of biological and chemical methods. It also utilizes advanced equipment when necessary.
Different Types of Sewage Treatment Plants
A sewage treatment plant is a drainage system that treats waste coming from a property or industry to a certain point. It can safely re-enter the water cycle. It can enter groundwater reserves without causing damage to the local environment or ecosystem. There are many types of treatment plants available that work in different ways. The sewage treatment plants manufacturer will help in protecting the ecosystems Here is a list of the various types of systems.
- Activated Sludge Process (ASP)
The activated sludge process is one of the most common methods for treating wastewater. This solution is used in domestic systems. The concept is also used in larger sewage treatment plants. These systems consist of two main components: a biozone chamber and a settlement chamber. The sewage treatment plant manufacturer can help in this matter.
Once the waste from a property enters the tank, it enters the biozone. Within this zone, an air diffuser maintains the bacteria’s viability by providing them with oxygen. The bacteria that live inside the biozone help to break down the solids/sludge inside the system. The suspended solids inside the effluent will settle to the bottom of the tank before re-entering the biozone. The treated effluent, located towards the top of the settlement zone, is then discharged from the tank.
These systems are a cost-effective solution because they have no mechanical or electrical parts inside the tank, making them easier to maintain. However, the electric consumption for these systems can be higher than that of other systems on the market, as the air diffuser operates most of the time. The installation costs of these systems can be high compared to those of different systems.
- Fixed Bed Reactor
A fixed-bed reactor system combines both media and aeration to treat waste generated from a property. Unlike most treatment plants, these systems have three chambers: a primary settlement chamber, a secondary treatment chamber, and a final settlement chamber. These systems are easy to install and require only power to the compressor. It powers the diffuser at the bottom of the secondary chamber.
Non-electrical Filter
Non-electrical treatment plants do not require any power to the unit. Everything is treated via gravity. This system consists of two chambers: the primary settlement chamber and the treatment chamber. The best thing about this system is no power is required. It means the running costs are relatively low compared to other systems on the market. There is no power in the system; the outlet is located towards the bottom of the tank. It means the invert level of the outlet is low. This means you either need a pumped outlet, which requires power, or you need to install a soakaway deep into the ground, which can be costly. It’s also worth bearing in mind that where there is high groundwater, a soakaway would not be a suitable solution.
Sequence Batch Reactor (SBR)
SBR sewage treatment plants are renowned for their high-quality effluent level after treatment. These systems have a primary settlement chamber and a secondary chamber. It works similarly to an ASP system. Although these systems tend to be more expensive than other systems on the market, SBR treatment plants exhibit exceptionally high cleaning performance. There are no moving or electrical parts inside the tank itself. They have very low maintenance costs. The sewage treatment plant supplier will help with this system.
The Conclusion
Choosing the right sewage treatment plants is crucial for efficient wastewater management. It is also vital for environmental protection. Each type of system offers unique benefits tailored to specific needs. Capacity, space, and regulatory compliance play a key role in the selection process. Whether for residential, commercial, or industrial applications, investing in the right systems ensures cleaner water and a healthier ecosystem.
