Global projects

We’re working with manufacturing partners around the world to meet the needs of the $1tn global water market, delivering multiple projects, including lithium enrichment, municipal water reuse, pharmaceutical process water and industrial Zero Liquid Discharge (ZLD).

How we work

Salinity Solutions is a technology development company. Once a new project is identified, we work with specialist delivery partners who design, manufacture and operate systems for our customers. We also have six patents and a strategy for continuous improvement, supported by our ongoing collaboration with University of Birmingham.

Global Projects

Food and beverage
F&B: A global food giant wants to reduce the amount of freshwater used in manufacturing. They want to install HyBatch process after their current RO to minimise water losses
- Reduced chemical use
- Lower energy consumption
- Reduce water consumption and waste volume by increasing the recovery
Vertical farming
Vertical farming is already a smart use of water, GrowUp Farms want to reuse as much of their wastewater as possible. Field trial showed we can reuse up to 98% of their wastewater at less than 1 kwh/m3
- Increase permeate water quality
- Reduce water consumption and waste volume by increasing recovery
- Lower energy consumption of total system (< 1 kwh/m3)
Pharmaceutical
A pharmaceutical company requires ultrapure water for production process. Current conventional RO process consumes a lot of energy, relies heavily on water softening and is limited to 75% recovery
- Reduction of pre-treatment & chemical consumption
- Reduction in energy consumption
- Reduce water consumptions and waste volume by increasing the recovery
- Increase permeate water quality
Municipal Phosphate removal
Water companies looking to remove P and other nutrients without chemical dosing. Generation of P credits to sell to developers allows process to be self funding.
- Effective and efficient P removal
- Reduced chemical usage
- Containerised plug and play solution (no civils)
Lithium brine extraction
SQM is Chile’s largest lithium producer. They want to move their Li enrichment process from evaporation ponds to membranes
- Increase lithium yield
- Reduce energy consumption of membrane process
- Reduce water consumption
- Increase quality permeate
Municipal water reuse
As water scarcity and droughts increase around the world and demand for Direct to Potable (DTP) is growing, Suez are looking for the next big technology for water reuse.
- Increased recovery of reusable water (up to 98%)
- Reduced energy consumption of the reuse process (<1kwh/m3)
- Reduced chemical consumption in acid/anti-scalant dosing and reduced CIP frequency
Industrial water reuse
Electroplating facility has strict regulations on disposing of Chromium III. HyBatch has been installed to both recover water from their waste for reuse and to reuse recaptured Chromium III in the production process.
- Reduce water consumption and waste volume by increasing the recovery
- Reduce energy used for dealing with wastewater (up to 98% reduction)
- Reduction in downstream treatment technologies (full circular economy) due to high concentration of brine/high recovery
Zero Liquid Discharge
India has introduced strict laws on zero liquid discharge (ZLD), Salinity has partnered with a high-efficiency evaporation technology, in which our HyBatch process drastically reduces the demand on the evaporator, thereby reducing the energy consumption of the whole process.
- Reduced energy consumption (increase in recovery drastically reduces evaporation volume)
- Recovery of freshwater for reuse (reducing overall water consumption)
Zero liquid discharge
Toshiba is looking for a potential replacement for their existing high pH RO process for Zero Liquid Discharge.
- High recovery
- Reduced energy consumption
- Reduced CIP frequency (reduction in scaling)

Case studies

Testing the impact of HyBatch Reverse Osmosis technology on vertical farming as a step towards Zero Liquid Discharge (ZLD)

Agriculture is the largest user of water globally. Vertical farms – farming on vertically stacked layers – use between 70% and 90% less water (and therefore nutrients and fertilisers), however their holy grail is to operate a closed-loop production system in which all water and nutrient is recycled, known as Zero-Liquid Discharge (ZLD).
