Have you ever had the question of how to treat the wastewater from a high-speed railway or train? In fact, there is usually a sewage tank at the bottom of a high-speed railway and train to collect sewage and feces. When the high-speed railway and train arrive at the station, there will be pickup trucks to deal with the waste.

When the pickup trucks working, it needs the help of a side channel blower to provide huge power to work. The vacuum pump in the pickup trucks draws out the air in the sealed tank to form a negative pressure with the help of a side channel blower, and the dirt is pressed into the tank through the suction pipe by using the atmospheric pressure outside the tank. During blowdown, the vacuum pump will put the atmospheric pressure outside the tank into the tank, and use the air pressure to discharge the dirt out of the tank. In this process, the regenerative blower plays a critical role in providing continuous power.

The sewage treatment system of high-speed railway and train is a relatively complex work flow, so how to deal with it? Because the sewage and excreta from high-speed railway contain a lot of phosphorus, we can use chemical precipitation method to treat them. Chemical precipitation is a method to remove phosphorus containing wastewater. It uses metal ions and phosphates produced by calcium salt and iron salt to form insoluble phosphate precipitation, so as to remove phosphorus from wastewater. Besides, biological methods can also effectively remove phosphorus from wastewater. Biological method refers to phosphorus based bacteria, under aerobic and anaerobic conditions, alternate to achieve the removal of phosphorus in wastewater.

The development of China’s high-speed railway (HSR) has become very mature, with a design speed of 250 – 350 km / h (155 – 217 mph). China’s high-speed railway is the world’s longest high-speed railway network and widely used worldwide. Moreover, China’s high-speed railway accounts for two-thirds of the world’s total high-speed railway. It is foreseeable that the application of side channel blowers in wastewater treatment system of high-speed rail will be more and more extensive.

With the increasing use of high-speed rail and trains, more and more regenerative blower suppliers have been attracted to enter this field. GOORUI is one of the blower OEM/ODM among them. GOORUI side channel blower has a wide range of applications, not only for sewage treatment system, but also for fish pond aeration, packaging industry and so on.
