The role of aerobic tanks in wastewater treatment is to allow activated sludge to perform aerobic respiration, further decompose organic matter into inorganic matter, and remove pollutants. Good operation requires controlling the oxygen content and other conditions required by microorganisms to be optimal, so that microorganisms can perform aerobic respiration with the greatest efficiency.

Recirculating Aquaculture Systems (RAS) are modern, sustainable approaches to fish farming. These systems rely heavily on advanced water treatment technologies to maintain water quality. Among these technologies, disc diffusers play a crucial role in providing aeration, a vital component for the health of aquatic organisms and the overall system efficiency.

Aeration is an essential component in wastewater treatment, designed to introduce air or pure oxygen into biological reaction tanks. This process increases the dissolved oxygen (DO) concentration, promoting the growth and metabolic activities of aerobic microorganisms, thereby effectively degrading organic matter and other pollutants in the wastewater.

How to treat industrial wastewater

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.

MBR membrane components have two filtration methods: intermittent filtration and simple continuous filtration. Intermittent filtration is usually used, and sometimes a simpler continuous filtration method is used. Regardless of which method is used, aeration must be carried out continuously during filtration operation.

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.

In the sewage treatment process, the collapse of the nitrification system is a serious problem, which may cause the effluent water quality to be substandard, affecting the environmental quality and the subsequent treatment effect. How should we deal with it?
