The oxidation ditch process, as a mature activated sludge sewage treatment process, has been widely used throughout the country.

The A/O process was produced in the 1970s. Because it has the functions of degrading organic matter and denitrification at the same time, and is easy to operate and manage, it has been widely used. Since the sewage treatment process is determined based on many factors such as the amount of sewage, water quality, effluent requirements and local actual conditions, small and medium-sized urban domestic sewage treatment stations generally use A/O and other processes.

In the world of wastewater treatment, aeration basins play a crucial role in facilitating the biological degradation of pollutants by using activated sludge. Proper operation and management of aeration basins are essential to maintain treatment efficiency and ensure that wastewater treatment processes meet environmental standards.

In recent years, the wastewater treatment industry has undergone significant transformations, driven by advancements in intelligent technologies such as the Internet of Things (IoT), big data, and artificial intelligence (AI). These technologies have allowed for enhanced automation, real-time monitoring, and more efficient management of wastewater treatment processes, leading to significant improvements in operational efficiency and energy savings.

The sedimentation tank is a commonly used device in the water treatment process. Its main function is to make the solid particles in the water settle to the bottom of the tank through gravity, achieving water purification. Sedimentation tanks are widely seen in diverse water treatment systems, including tap - water treatment, sewage treatment, and industrial wastewater treatment.

A Drum Filter, also known as a Rotating Drum Filter, is a highly efficient water treatment device designed to remove suspended solids and impurities from water or wastewater. It is widely used in municipal wastewater treatment plants, industrial processes, and other applications where water filtration is critical.

In wastewater treatment systems, aeration diffusers (or aerators) play a critical role, particularly in improving oxygen dissolution and supporting microbial metabolism. To ensure that aeration diffusers maintain optimal performance over time, regular maintenance and care are essential. AquaSust's aeration diffusers are known for their high efficiency, durability, and eco-friendly design.

Dissolved oxygen (DO) plays a critical role in the biological treatment of wastewater, supporting the metabolic activities of microorganisms that break down organic pollutants.

Water pollution is the focus of discussion in today's society. In order to make industrial wastewater reach the discharge standard, many factories have used sewage treatment equipment.

Reasons why the effluent of the integrated water treatment equipment does not meet the standards:
