Wastewater Treatment Technology

A2/O process is the abbreviation of Anaerobic Anoxic Oxic, which is the abbreviation of biological nitrogen and phosphorus removal process. The treatment efficiency of this process can generally reach: BOD5 and SS are 90%~95%, total nitrogen is over 70%, and phosphorus is about 90%. It is generally suitable for large and medium-sized urban sewage plants that require nitrogen and phosphorus removal

In the field of sewage treatment, accurate addition of carbon source is one of the key factors to ensure stable and efficient treatment effect. However, excessive addition of carbon source is a common operational error, which may trigger a series of chain reactions and affect the stability and effluent quality of the entire sewage treatment system.

In the process of sewage treatment, we often encounter the phenomenon that the activated sludge in the aeration tank does not grow or even decreases. What is the reason? And how to solve it?

With the advent of winter, the temperature gradually drops, which has a significant impact on the sludge activity in the sewage treatment process. In low-temperature environments, microbial activity weakens and the biodegradability of sludge decreases accordingly, thus affecting the efficiency and stability of the entire sewage treatment system.

Ultrafiltration membrane operation detection

The AquaSust Single Screw Pump is a reliable and efficient solution for pumping viscous, abrasive, or shear-sensitive liquids in various industrial applications. This type of pump operates on a unique design, offering advantages like a gentle pumping action, steady flow, and the ability to handle a wide range of materials, from liquids to sludges.

In today's water treatment field, MBR membrane and ultrafiltration membrane are two commonly used water treatment technologies. Although they both play important roles in the water treatment process, there are obvious differences in technical principles, application fields, performance characteristics, etc. This article will elaborate on the MBR membrane and the ultrafiltration membrane to help readers better understand the differences between the two technologies.

Every year, the sewage treatment system experiences expansion, which is very periodic! In fact, many sewage treatment systems do not experience serious sludge expansion in summer with high temperatures or in winter with cold temperatures. It often occurs during the seasonal transitions between spring and summer, as well as autumn and winter. That is, in an environment of alternating air temperature, water temperature, and air pressure.
