Tuesday, April 16th SUEZ, a global leader in environmental services, and Salinity Solutions, an engineering technology company based in Birmingham (UK), have signed an agreement to pilot an innovative reverse osmosis system at a fully operational wastewater treatment plant in France.  

Salinity Solutions’ HyBatch, a ground-breaking batch reverse osmosis (RO) technology – the first in the world to be manufactured commercially – has been developed to reduce the environmental impact of water treatment. Salinity’s system uses less energy, purifies a higher amount of wastewater, generates less waste, and is more compact than traditional RO systems.

Jörg Linsenmaier, Executive Vice President for SUEZ Engineering and Construction and Member of Executive Committee: “SUEZ is constantly seeking ways to enable customers to provide access to water services with resilient and innovative solutions. The aim of this partnership is to optimise the re-use of a high-quality wastewater to increase the availability of water, while simultaneously reducing energy and chemical usage.”

Following successful lab trials and a scale-up study over the last 18 months, SUEZ has ordered a unit to be installed later this year. The aim of the pilot is to evaluate how HyBatch – which was initially trialled as a method of concentrating and extracting minerals from brackish flows – can improve  on conventional reverse osmosis, to  remove salts and contaminants such as pharmaceuticals, heavy metals and PFAS from wastewater.

Salinity Solutions’ CEO, Richard Bruges, commented: “I’m delighted to formalise this partnership with SUEZ, which is a tremendous milestone for our company. With global water demand set to double over the next five years, efficient wastewater reuse is essential. Water treatment currently consumes 4% of the world’s total electricity production and conventional reverse osmosis systems are energy intensive.  Working with SUEZ, we can bring significant energy and water savings to the municipal sector and other industries.”

The advanced treatment solution will contribute to promoting wastewater as a new resource, particularly in coastal regions such as the Mediterranean that are exposed to saline intrusion into groundwater resources and sewer networks. 

About Salinity Solutions

Launched in 2021 as a spin-off from the University of Birmingham in April 2021, following 10 years of research and development at Aston University and University of Birmingham under the supervision of Professor Philip Davies, Salinity Solutions addresses two of the biggest challenges in sustaining human life on earth – water and energy. The company has developed a game-changing batch reverse osmosis water purification technology, which uses half the energy of traditional reverse osmosis methods. Its patented, commercially viable solution has been described as the biggest step forward in water treatment in 50 years and has the potential to benefit every corner of the globe – from wastewater clean-up and high value mineral extraction to rural drinking water supply. http://www.salinitysolutions.co.uk/
