The wastewater treatment plant at L'Oreal's Suzhou factory in China has been designed specifically with the company's carbon and water footprint in mind.
The solution combines two VWS patented technologies: Biothane® Biobulk CSTR and Anoxkaldnes™ MBBR.
With this design, L'Oreal has seen an 8.5% reduction in energy consumption; 58% reduction in sludge production; and the elimination of high concentrated liquid waste, which is now treated in the wastewater treatment plant.
In addition, the total CO2 emissions of the wastewater treatment plant have been reduced by 43%.
The wastewater treatment plant design also allows for future expansion and the need to address water challenges. For example, a reclaim system could be implemented for the utilities of the manufacturing plant (e.g., sanitary, cooling system) to reduce the factory's overall water consumption.
