There are a number of sewage treatment plants that are installed around cities in China, a country with a dense population. There are a number of sewage treatment plant suppliers that supply the equipment necessary for sewage treatment, to the sewage treatment plants.
Sewage treatment simply refers to a process in which contaminants and harmful products are removed from sewage. Since sewage is extremely contaminated, it has to undergo a range of physical, chemical, and biological processes for the removal of the innumerable contaminants that it has. Ultimately, a safe effluent is produced. At the same time, the byproduct is a sewage sludge which is a semi-solid slurry. Before being suitable for application of lands, this semi-solid slurry is processed even further.
Sewage treatment is also often referred to as wastewater treatment. This is because it may also include the treatment of wastewater that comes from the industries. In a number of major industrial cities, the sewage water also carries a big amount of wastewater coming from the industries. Often at times, the industrial wastewater has often undergone a number of treatments already for the reduction of harmful pollutants. The remaining is drained off into the sewage.
There are a number of processes that the sewage water undergoes in a sewage treatment plant. For instance, Anaerobic sewage treatment is the first process. It involves the breaking down of the sewage by the use of an anaerobic bacteria in a tank, in the absence of air. As a result of this, the organic content gets reduced to hydrogen sulfide, methane and carbon dioxide.
The primary treatment at the same time involves flowing the sewage through primary sedimentation tanks. These tanks settle the sludge down whereas the oil and grease are removed from the top.
In the secondary treatment, biological waste such as food waste, detergent, and human waste are degraded. After this process, the effluents are clean enough to go into the rivers.
Then comes the tertiary treatment, followed by sludge treatment.
Why Hydro Blue?
In this regard, the Hydro Blue has played a great role in China by being the major supplier of MBR system wastewater treatment, filtration membrane, UF membranes, membrane bioreactors, and a lot more.
From a while now, Hydro Blue membrane technology CO., LTD. has been involved in the R&D, manufacturing, and distribution of sewage plant, Ultrafiltration hollow fiber membranes, design and guidance of sewage plants, after sale services, and wastewater solutions. The company owns a number of patents for UF membranes that include PAN, PS/PES, PVDF, and Alloy-PVC.
The company also specializes in a number of typical UG sewage treatment cases that include gravity filtration, MBR wastewater polishing projects, sewage treatment of industrial wastewater, and a lot more.
