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.

When setting up a fish farm, calculating the right amount of MBBR (Moving Bed Biofilm Reactor) is essential for maintaining a healthy environment for the fish. Below are some practical methods and reference values to help you estimate the required MBBR and biofilter volume.

Centrifugal Blower and Roots Blower in the pneumatic conveying of powder and granular materials are more widely used fan types, many people, although they know that they need to distinguish between the application occasions, but for the two kinds of fans between the principle of manufacturing, the difference between the parameters instead of a half-understanding.

In the field of biological nitrogen removal, short-range nitrification and short-range denitrification are two important technological processes. They break through the traditional full-range nitrification and denitrification path and achieve efficient nitrogen removal by regulating the structure of the microbial community.

Sludge bulking is a common abnormal condition in the activated sludge process , resulting in poor settling performance， failing to meet the requirements for oxidizing and decomposing pollutants, ultimately resulting in an effluent BOD5 level exceeding standards .

The MBR process is a key step in sewage treatment. Next I will introduce the MBR (Membrane Bioreactor)process flow and design calculation.

Recirculating Aquaculture Systems (RAS) represent a transformative technology in aquaculture, enabling sustainable and efficient fish farming by recycling water within a closed system. This approach has become essential in modern aquaculture, addressing challenges such as water scarcity, environmental impact, and fish health management. Here, we will explore the fundamentals of RAS, highlight its advantages, and showcase how AquaSust products support a robust and efficient RAS setup.

Roots blowers, known for their robust construction and consistent performance, are essential components in many industrial applications, particularly in wastewater treatment. These blowers use a unique design，effective for various processes that require consistent air supply. In this article, we’ll explore how Roots blowers work, their key benefits, and why they are particularly suited for wastewater treatment and other industrial applications.

When setting up a fish farm, calculating the right amount of MBBR (Moving Bed Biofilm Reactor) is essential for maintaining a healthy environment for the fish. Below are some practical methods and reference values to help you estimate the required MBBR and biofilter volume.

The MBBR (Moving-Bed Biofilm Reactor) process is an advanced wastewater treatment technology that has gained considerable attention in recent years. It uses suspended carriers to provide a surface for microorganisms to attach, addressing the issues of periodic backwashing and complex maintenance required by traditional reactors. This makes it an efficient and simple treatment method. This article provides a detailed introduction and explanation of MBBR.
