On one hand, water is by nature source of energy: water may contain heat or chemical energy, water flow makes hydraulic turbines turn and work… But on the other hand, water consumes energy when it’s heated, cooled or treated.

Nowadays, producing highly cleaned water from very dirty water consumes a lot of energy. Therefore, Nereus has invented a system combining water recycling and energy saving. According to the United Nations, almost one-fifth of the world’s population lives in areas where water is physically missing and 500 million people are approaching this situation. Another 1.6 billion people, which is one quarter of the world’s population, face economic water shortage. Thus it’s essential to learn now how to use several times water we take away from nature…

A division of HILLSBRIDGE Investment Group S.A.

What solution was used before NEREUS?

“The recycling solution previously used was significantly undersized and quality of recycled water was thus not reached and did not meet international standards.

We provide thanks to that new water recycling era offering security, durability and guarantee efficiency.”

How is this solution beneficial for your organization?

“The water recycling unit built by NEREUS and acquired by HILLSBRIDGE is durable and without inconvenience to the end user: durable because teams have more than thirty years of experience in membrane technologies and thus offer a viable solution; without disadvantage because the energy cost is limited, the equipment is compact, the maintenance is low and it’s not necessary to create an additional post.”
