The Bailonggang wastewater treatment plant in Shanghai is the biggest in Asia and one of the largest in the world. With a population in the double-digit millions, a third of the wastewater produced in the city is treated here. Every day over two million cubic meters of wastewater flow through the plant, which handles the wastewater from around 3.6 million inhabitants in a catchment area covering more than 270 km².

Hundreds of pumps were needed to equip the wastewater treatment plant. The operating company opted for KSB as the supplier because KSB pumps meet all relevant requirements, deliver higher levels of hydraulic efficiency than many competitor products and thus make a major contribution to the overall energy efficiency of the pumping system.

Amacan submersible pump in the discharge tube

KSB supplied a total of 241 submersible motor pumps from the Amacan range, 65 from the Amarex KRT and Amarex N ranges, six dry-installed SPN wastewater pumps, and six dry-installed ZL axial flow pumps. The pumps were delivered with all requisite components ready for connection, some already with the necessary control cabinets.

Comprehensive portfolio for wastewater applications

KSB offers you a comprehensive portfolio of pumps for tackling all wastewater treatment tasks. You’ll find not only classic wastewater pumps, but also sludge handling pumps, progressive cavity pumps, propulsive jet pumps for stormwater tank cleaning, and clean and hot water pumps for general use. Whatever the application, reliability always takes top priority. KSB, therefore, sets great store by choosing the most suitable hydraulic system for wastewater handling, selects especially wear-resistant materials or incorporates carefully considered details such as absolutely watertight cable entries and mechanical seals with a covered spring for particularly abrasive wastewater. We also offer a wide range of mixers that prevent sludge deposits in sedimentation tanks and ensure that contaminants are fully eliminated. The Amaprop low-speed mixer, for example, is one of the best products in its segment on the market – a powerful performer with an optimized hydraulic system, a break-proof propeller, and especially long maintenance intervals. Last, but not least come our reliable valves such as the HERA knife gate valve. They ensure the precise control of all processes in wastewater treatment.
