1. Activated Sludge Method Process and Principle: The typical activated sludge method consists of an aeration tank, sedimentation tank, sludge recirculation system, and excess sludge discharge system. Wastewater and recirculated activated sludge enter the aeration tank to form a mixed liquor. Compressed air, supplied by an air compressor station, is introduced into the wastewater in […]

With the continuous advancement of fruit and vegetable juice processing technologies and the increasing demand for differentiated product standards, the market for concentrated fruit and vegetable juices has become more stringent and refined. To achieve high-quality juice products, it is essential to remove or adjust certain components during the processing. Adsorption separation technology offers unique

Chlorinated hydrocarbons, such as methylene chloride, ethylene dichloride, and chloroform, are commonly used as solvents or synthetic raw materials in industries like pharmaceuticals, pesticides, and fine chemicals. However, due to their relatively low boiling points, these chlorinated hydrocarbons tend to volatilize significantly during production, causing material loss and creating environmental pressure due to the waste

Under the dual pressure of industrial production and environmental protection, fluoride-containing wastewater treatment technology has attracted unprecedented attention. Traditional defluorination processes, such as chemical precipitation and flocculation, while solving some of the issues, often suffer from low efficiency, high costs, and complex operations. Southwind offers an innovative solution with its new nanotechnology-based fluoride removal resin,

Nuclear energy, as an efficient and clean energy source, plays a crucial role in human development and sustainability. Uranium, the primary fuel for nuclear reactors, is utilized for nuclear power generation. Its isotope, uranium-235 (U-235), undergoes fission within nuclear reactors to produce heat energy, which is subsequently converted to mechanical and then electrical energy. Due

In the sugar industry, decolorization of syrup, sucrose, and MSG is a key step in enhancing product quality. Traditional decolorization methods, such as using activated carbon, are effective but costly and difficult to regenerate. As a result, more sugar manufacturers are turning to sugar decolorization resins, using ion exchange resin technology to achieve higher efficiency

Ultra-pure water, also known as UP water, is water with a resistivity of 18MΩ·cm (25°C). Polishing mixed bed resins are designed to remove almost all conductive substances from the water, as well as colloidal matter, gases, and organic compounds, to very low levels. Main Process Flow for Preparing Ultra-Pure Water with Polishing Resins: HaiPu Polishing

With the rapid development of the photovoltaic industry in recent years, a large amount of fluoride-containing wastewater has been generated during the production of silicon solar panels. The water quality of this wastewater is characterized by strong acidity and alkalinity, high fluoride ion concentrations, and poor biodegradability, making fluoride removal challenging. The stricter discharge standards

What Is Anthocyanin? Anthocyanin, also known as anthocyan, is a type of water-soluble natural pigment widely found in plants. Its color varies with pH levels: red at pH = 7, purple between pH 7 and 8, and blue when pH > 11. Known for its health-promoting properties, anthocyanin is widely recognized for its ability to
