Food sector’s water-purification technology trial

Trial aims to reuse wastewater at vertical farm

Great to see Salinity’s trial at GrowUp Farms has been picked up by The Engineer:

Salad grower trials new water-saving technology

We have teamed up with indoor salad producer GrowUp Farms at their vertical farm in Sandwich, Kent, for a 10-day trial to reduce wastewater. Wastewater from the growing process, as well as elsewhere on the site, was collected and re-circulated twice, using our unique batch reverse osmosis technology.

Trial brings hope for phosphate mitigation funding

This article from Water Magazine highlights that Somerset Council is hoping to secure Government funding to deliver phosphate mitigation measures, which will unlock the delivery of 18,000 new homes across the area and provide for longer term nature recovery.

Through our recent trail with Somerset Council and Wessex Water we have been given the opportunity to demonstrate our technology as an effective phosphate and nitrate removal solution. This trial has now brought hope for their phospate mitigation funding, and has shown that our technology has the potential to assist all the nutrient neutrality catchment areas by providing a cost effective solution.

Water Desalination Report: August 2023 

An article published this week by Water Desalination Report details how our Batch RO system could be the nutrient removal solution for Somerset Council, following our recent field trial at the Fivehead Wastewater Treatment Works. The Council wishes to expand their existing phosphate credit scheme to allow for the development of a backlog of 18,000 new homes and provide for long-term nature recovery.

US-based WDR is well-established around the globe for its insight on desalination and advanced water treatments. It is respected by senior decision makers in the water treatment sector and will certainly help to put us on their radar.

WDR is subscription-only, but they have kindly given us this excerpt to share:

Pilot Trial Success

We’re very pleased that Sarah Dyke, the recently elected MP for Somerton and Frome, stopped by yesterday to see for herself our innovative energy efficient and chemical-free solution for removing phosphate and nitrate from municipal wastewater.  
Sarah’s visit follows Rebecca Pow’s ministerial visit on Monday, alongside representatives from various government departments.  
As we wrap up after two weeks on site, we’d like to thank everyone who has helped to make the pilot trial possible and such a success – Somerset Council for inviting us, Wessex Water for hosting us and Te-Tech Process Solutions, our manufacturing partner, for all their technical and logistical support.

Pilot Trial Site Visit by Rt Hon Rebecca Pow MP

A huge thank you to Rt Hon Rebecca Pow, MP for Taunton Deane and Minister for Environmental Quality and Resilience, for taking the time to visit our pilot trial site in Somerset this week. The trial is currently running at Wessex Water’s Fivehead sewage treatment works, where we are demonstrating the effective removal of dissolved nutrients such as phosphate and nitrates, which are otherwise discharged into rivers, causing environmental contamination. Early indications show very promising results with the first verified laboratory results showing over 98% of phosphates and 88% of nitrates removed. Check out the minister’s Tweet below: 


The system is 50 per cent more efficient than existing technologies and recovers 75 to 85 per cent of water

Spotted: New data suggests that urban methane emissions may have been inadvertently underreported by a factor of three to four. When assessed across cities around the world that have populations of two million or more, the amount of underreported methane emissions could be nearly 22 per cent of the global total. Interestingly, the amount of methane correlates with the “estimated rates of untreated wastewater.” 

Treating wastewater is an expensive process and is estimated to use up to three per cent of global energy output. As a means of reducing the carbon footprint of the water treatment industry, UK’s Salinity Solutions has created a system, called SAM50, with such a small footprint that it fits inside a 20-foot shipping container.  

The SAM50 system’s efficiency is extremely high, using approximately 0.8 kilowatt hours (kWh) per cubic metre of water. Each unit processes up to 26 cubic metres of water per day and has been designed for quick installation and plug-and-play use. The system uses reverse osmosis technology to treat effluent and brine, extract minerals, and produce reusable water. Salinity Solutions’ patented pressure exchange process significantly reduces the amount of energy required to run the system, and the reverse osmosis separates highly concentrated volumes of minerals and other materials from the water.  

Salinity Solutions’ first in-field trial of the system was held in Cornwall with Cornish Lithium and concentrated the lithium found in shallow geothermal waters. 

Water is such an important global resource that Springwise is spotting a range of innovations making it easier and more sustainable to clean it, like a solar-powered method and a system that also generates energy during the purification process.

Startups & Disruptive Tech: Salinity Solutions

Founded in 2021, Salinity Solutions has developed a patented system that promises to purify global water supplies while consuming half of the energy used in conventional methods.

The startup, which was established in Coventry by Professor Philip Davies and Timothy Naughton, has already raised over £3.2 million in grant funding and more than £1.3 million through crowdfunding efforts. 

Company mission 

Salinity Solutions intends to address two of today’s most pressing challenges: the declining availability of freshwater supplies and the excessive consumption of non-renewable energy

“The world needs more fresh water, our energy consumption needs to be reduced, and our environmental impact needs to improve,” explains Naughton. “Our passion for water treatment is founded in a very real concern: the demand for freshwater is on the increase while the world’s supply is steadily decreasing.” 

With just 0.5% of the world’s water available as a usable resource, its value to society cannot be overstated. Indeed, water is essential to human survival, economic development, food production, global peace and the health of natural ecosystems. 

Currently, however, our water supplies are in a state of rapid decline. Over the past two decades, terrestrial water storage has been declining by around 1 centimetre each year. This trend is being driven by a number of factors, including population growth, climate change and the ongoing expansion of intensive industrial activity. 

As these factors continue to evolve, estimates suggest that water scarcity will reach the global level as soon as 2030. By 2050, more than five billion people will lack sufficient access for at least one month per year. 

Effective water treatment can ensure that remaining water supplies are kept as a safe and renewable resource but, with most available treatment technologies being extremely energy intensive, the environmental trade-offs involved may only worsen the problem. 

Conventional technology gets an innovative upgrade 

“Salinity Solutions provides a compact and highly efficient water treatment system that will dramatically reduce the energy footprint of a wide range of industrial processes,” says Naughton. The system is based on reverse osmosis, which uses a change in pressure to clean the water by pushing it through a semi-permeable membrane. 

“Reverse Osmosis (RO) is one of the most effective forms of water treatment, but conventional systems are energy intensive and produce too much waste,” Naughton explains.  

“Salinity’s high efficiency Batch RO technology is the first commercialised example of next generation Reverse Osmosis. Its patented system uses less than half the energy of conventional RO, while delivering market leading recovery rates by recirculating the feedwater around the membrane. Its pressure process reduces the average pressure in the system, dramatically reducing pumping energy.”  

Overall, Naughton claims that the technology uses up to 70% less energy than conventional RO while reducing waste by approximately 80%. 

Target market 

According to Naughton, the SAM50 system can be used in applications including environmental clean-ups, water recycling and mineral extraction. With its diverse functionality, the company is targeting industries ranging from municipal wastewater treatment to mining, manufacturing and agriculture. 

“We believe that adoption of this technology will have an impact in every corner of the globe, across every layer of society, from rural drinking water to large industrial processes,” says Naughton. “We’ve already identified at least 20 different sectors which could benefit. Our immediately addressable market is worth €26bn in an industry that will turn over €470bn by 2028.” 

Next steps to commercial expansion 

Though there is clearly a market for its technology, Salinity Solutions will have to overcome a number of hurdles on its road to commercialisation. 

“Our biggest challenge, which will also demonstrate market viability, is to achieve mass adoption of the technology,” Naughton explains. “To achieve rapid adoption, we need to find global licensees for the technology. For this to happen, we need to raise awareness of our work and build our credibility in the water treatment industry, promoting visibility among investors, potential partners, customers, and buyers.” 

Nonetheless, the startup appears to be making progress. It has recently entered into an agreement with Te-Tech, an established manufacturer of water processing solutions, to produce a line of bespoke units that are to be sold into three different industries within the coming year. The company has also partnered with Cornish Lithium, enabling it to demonstrate its technology in an initial field trial. 

“Our next milestone is the conclusion of successful field trials that we are undertaking for municipal wastewater clients.” says Naughton. “In the meantime, we will be looking for additional investment to enable further development of the product and participation in other field trials.” 

As it advances towards its commercial expansion, Salinity Solutions will continue to search for collaborative opportunities while harnessing the support of its local community. 

“We can imagine greater collaboration between the different water treatment technologies (pre-treatment, post-treatment, dosing etc) to help create low-carbon treatment system chains. By working together there can be a greater emphasis on energy reduction of total systems, not just individual components,” Naughton observes. 

“We feel very fortunate to be based in the West Midlands, close to Birmingham, which has rapidly become an epicentre for burgeoning tech start-ups and provides a source of growing talent,” he continues.  

“The city is extremely supportive of entrepreneurs, proving a wealth of incentives, funding and support to ensure companies survive those early business years. We have recently won a grant to allow us to move into a bespoke site adjacent to the Birmingham Energy Institute. Also, as a University of Birmingham spinout company, we benefit greatly from the ongoing assistance offered by its enterprise arm, including PR, investment and governance.”
