10sets RAETTS air bearing blower help customer to save more than 200,000$ in electricity each year

Project Name: Phase I project of Mabaolong Sewage Treatment Plant in Yilong Town, Shiping County, Yunnan Province,China.

Before the renovation of the project: the traditional centrifugal blower has high energy consumption, high noise and high maintenance cost.

After the renovation of the project: 10sets RAETTS air foil bearing blower (2sets EXPL 75-06 55kW; 2sets EXPL 100-06 75kW; 6sets EXPL 50-06 37kW)

The main parameters:

EXPL 75-06 55kW flow rate 51m³/min, pressure 60kPa

EXPL 100-06 75kW flow rate 34m³/min, pressure 60kPa

EXPL 50-06 37kW flow rate 70m³/min, pressure 60kPa

Energy saving effect: about 30%

Annual electricity saving: 10sets RAETTS air bearing blower can save more than 200,000$ in electricity the whole year.

Payback cycle: estimated one year

Project Introduction:

This sewage treatment plant in Shiping County, Honghe Prefecture, Yunnan Province is located in Mabaolong, Yilong Town, Shiping County, covering an area of 5.54acres. It has built two biochemical pools with a treatment scale of 10,000 m3/d and one storage tank with a capacity of 8000 m³, and adopts CASS+ advanced treatment Process, factory water quality implementation standard is “Urban Sewage Treatment Plant Pollutant Discharge Standard” (GB18918-2002) Class A standard. The scope of service is the urban area of Shiping County, and the service population is 62,500 people recently. The project started construction in October 2009 with a capacity of 10,000 m3/d. It was completed on December 31, 2010 and tested for water supply. It was officially put into operation on September 22, 2011. In May 2013, it passed the environmental protection inspection. In October 2017, the construction of the first phase relocation project of 10,000 m3/d was completed and put into operation, and the processing scale is now 20,000 m3/d.

Before the upgrade and renovation, the Shiping County sewage plant used traditional centrifugal blower for blowing and aeration, which consumes a lot of energy, makes a lot of noise, and requires high maintenance costs. After researching and understanding the status and needs of the project, RAETTS professional technicians selected 10 sets of conventional pressure air suspension bearing blower for the plant to meet the needs of various working conditions and achieve the purpose of good energy saving, noise reduction and low-cost maintenance.

Customer Reviews:

RAETTS air bearing blower adopts international advanced air suspension technology. The whole machine is small in size, light in weight, free of oil pollution, and the noise is about 80 dB, which is much lower than the original centrifugal blower. Maintenance cost is very lower and no need to change the blower for operation frequently.Energy saving efficiency is very significant.
