Suez operates over 2,200 wastewater treatment plants (WWTP) throughout the world providing sanitation services for over 65 million people. Many of these plants employ the activated sludge process to treat the wastewater resulting in high energy consumption, high operating costs and high greenhouse gas emissions. In addition, some of these WWTP have been constructed several years ago, and require upgrading to meet more stringent effluent limits (typically tighter nitrogen and phosphorous limits) or to meet higher COD load than originally designed. Therefore, Suez is always on the lookout for treatment solutions that can increase the capacity of existing, overloaded, WWTP while at the same time reduce energy consumption.
Suez has a strong focus on research and development and is very excited by the potential of the
In 2015 Suez and OxyMem began a collaboration to test the potential of MABR to upgrade an existing WWTP from secondary treatment only to tertiary treatment. The Montcada
As Global Technology Leader for Jacobs’ Wastewater Treatment Practice, I and my team are constantly on the lookout for transformative and market disruptive technologies that can assist our clients around the globe. With its simplicity of implementation and demonstrated ability to couple process intensification with energy optimization (contributing towards a pathway to energy self-sufficiency), MABR is definitely a technology that we are excited about and are actively applying.

The MABR has been demonstrated as an excellent solution for upgrading existing facilities to achieve a secondary treatment standard. In particular, the ability of the system to act as an upgrade to simultaneously remove high loads of COD and ammonia is unique, when compared to other fixed film technologies. It should be noted that the lower loading rate of 1.1 kg COD/m3/d, is at least twice the loading rate of most activated sludge plants. The ability of the OxyMem MABR to achieve a very high effluent quality demonstrates the potential of the MABR to function as a standalone system.
