Grundfos flowmakers lower energy costs and improve efficiency at Guangzhou wastewater plant

China has the largest population the world. With large populations come large cities and the attendant need for efficient wastewater treatment in residential areas, such as the city of Guangzhou with its 6.6 million inhabitants. The city is situated in the southern part of China, at the mouth of Pearl River. With a history going back 2,200 years, it is regarded as the oldest among the international trade port cities in the world.

Because the Guangzhou wastewater plant is located near a residential area, it was crucial that a reliable and safe solution was implemented. The oxidation and deodorisation processes were both main concerns, and based on similar past successful projects in China, Grundfos was chosen to supply the flowmakers for the system. Grundfos’ ability to deliver vertical flowmakers with benefits such as energy-efficient operation, low installation costs and easy maintenance played a major part in the selection process.

Grundfos delivered a total of 54 units of unique vertical flowmakers, which compares favourably to similar products from other manufacturers by being more energy-efficient and easier to install.
The nominal power of the Grundfos vertical flowmaker is 2.2 kW, which is a very small energy consumption for an effective mixing of the total volume of the tanks.

As promised, both installation and operation have been easy
processes. The customer has been very satisfied with the products and service provided, which constitutes an ideal solution in terms of both efficiency and economy.
