Application of Peristaltic Pump in Sewage Treatment

In recent years, with the continuous advancement of industrialization and urbanization, the social economy has developed rapidly, but the accompanying pollution problem has also become an important problem to be solved urgently. Sewage treatment has increasingly become an integral part of economic development and water conservation. Therefore, vigorously developing sewage treatment technology and industrialization level is an important way to prevent water pollution and alleviate water shortage. The peristaltic pump head also played a big role in this process. 

Let's LEFOO peristaltic pumps manufacturers take you to have a look:

1. Working principle of peristaltic pump

Peristaltic pump is a kind of precision transmission equipment, which is assembled by driver, peristaltic pump head and peristaltic pump silicone tube. It transmits liquid through the extrusion of the silicone tube by the pump roller, and is widely used in sewage treatment, pharmaceutical industry, etc. because of its precision and hygiene.

Sewage treatment needs:

In the water treatment process of the factory, in order to ensure the quality of drinking water, accurate quantitative feeding is required in primary disinfection, secondary disinfection and pH control, and pumps with good sealing properties are required in these processes.

Chemical substances such as ferric chloride, sodium hypochlorite, chlorine, carbon, and lime often cause gear wear and pump blockage, resulting in reduced pump performance and reduced life. In particular, lime and polymer electrolytes will have a serious impact on the operation of the pump, and the usual solution is to replace the pump with a new one. At the same time, the performance of shear-sensitive flocculants is greatly reduced when passing through high flow, tortuous pump channels.

Therefore, safe and efficient chemical dosing and delivery is the goal of every wastewater treatment operation. The industry urgently needs a pump that can handle demanding applications to optimize the production process. While reducing maintenance work, it can reduce costs and improve processing efficiency. The above requirements are the advantages of peristaltic pumps.

2. Application of peristaltic pump in sewage treatment

As municipal and industrial wastewater treatment becomes more specialized and complex, the dosing, chemical delivery and product transfer operations that take place are critical.

In the sewage treatment plant, in the sodium hypochlorite feeding system, when the concentration of sodium hypochlorite needs to be diluted to 1%, it is easy to cause salt solidification in the conveying pipeline and storage tank.

Gas handling problems can easily arise due to the various hazards created by the accumulation of gas in the system. In this case, there is a need for a pump that is immune to gas handling, crystallization, has good chemical resistance, and that does not allow gas to accumulate in the pump head. However, due to its own characteristics, the peristaltic pump is completely competent in this process.
