A LOWER COST PROCESS FOR SEPARATING WATER FROM SALTS, HEAVY METALS & MINERALS
Based on a Natural Process
When salt water freezes, the ice is salt free
The crystal structure of ice rejects salts,
heavy metals, minerals and PFAS
50% LOWER CAPEX
35% LOWER OPEX
CryoDesalination is…
Less expensive than Reverse Osmosis
​
Reverse osmosis is energy intensive, has a large carbon footprint, and requires chemicals to prevent fouling & scaling. Additionally, the cost of RO equipment increases linearly with capacity, so doubling the capacity of a plant increases the cost of the RO equipment by 100%.
​
In contrast, CryoDesalination equipment scales exponentially, so doubling the capacity of a plant increases costs by only 25%. Furthermore, CryoDesalination uses less energy, has dramatically fewer parts, has no consumables, and does not require chemical pretreatment.
CryoDesalination is…
Less expensive than Thermal Desalination
​
Thermal desalination is often the last resort of high TDS waters because it can evaporate anything. However, this flexibility comes with a high price, massive energy usage, and a big carbon footprint.
The energy required to boil water is 6 times higher than to freeze it. This means that CryoDesalination plants have a natural cost advantage over thermal processes. In addition, CryoDesalination plants can be fabricated with common low-cost materials, unlike Thermal Desalination which requires exotic alloys required to resist corrosion from boiling salt water.
Applications
CryoDesalination is applicable when there is a need to reduce the cost of desalination, handle high salinity feeds, recover water, salts and minerals, or achieve zero liquid discharge.
Applications include:
-
Seawater desalination
-
Mining effluents and lagoon waste clearing
-
Producing nearly free water using waste energy from LNG regasification or Air Separation Units
-
Crystallization of chemicals & minerals
-
Fertilizer effluent and Gyps Stack clean-up​
-
Oil & Gas produced water desalination
-
Industrial wastewater purification​
-
Copper recovery from tailing ponds
-
Lithium, Rare Earth Elements, and Critical Materials concentration and recovery
-
Separation & purification of chemicals, pharmaceuticals, and juices​
-
​Brine concentration
Zero Carbon Emissions using waste energy from
LNG Regasification
CryoDesalination is the only desalination technology that can use cold waste energy from processes such as LNG regasification or Air Separation Units to eliminate GHG emissions and drastically cut costs.
When LNG is regasified, a huge amount of cold waste energy is released into the environment. We recover this cold energy by heat exchange to make ice. This eliminates energy costs and greatly reduces hardware costs. It's a zero emission process because no fossil fuels are consumed.

Freeze Desalination is Now Viable
Freeze desalination is not a new idea, ancient sailors traveling the Arctic would collect frozen sea ice, melt it, and use it for drinking water.
​
In the 1950s & 60s there was a lot of research on freeze desalination. However, they were unable to separate the ice from the brine at commercial scale. Due to the inability to overcome this ice-brine separation problem, interest in freeze desalination faded.
​​
CryoDesalination has solved this problem with our patented process using immiscible food-grade fluids with densities between ice and brine. This is the innovation that allows ice and brine to be separated in a continuously flowing, high-volume process. Our other innovations include crystallizers, power consumption optimizations, advanced process controls, and heat recovery methods.
