Utility water plants
The demand for plant-size desalination technology comes from regions and nations in need of long-term and reliable water supply for their populations and agriculture.
The global utility water desalination market was estimated to 13 billion USD in 2016 and set to reach 27 billion USD by 2025 equalling a CAGR of 8.1 percent according to Hexa Research.
More than 150 countries are utilizing desalination to supplement their freshwater resources. The Middle East and Africa account for 53 percent of the 2016 desalination market. Also, the US, Australia, China and India are heavy users. And the demand is expected to continue to rise in the future.
Below is shown the annual capacity and growth in global desalination capacity in million m3/day according to Global Water Intelligence, with reverse osmosis (RO) being the dominant technology with the fastest growth.
An average desalination plant produces around 100.000 m3/day. However, the market has also begun to look for other sizes.
An increasing amount of super-size facilities are showing up such as the Israeli Sorek plant which has a capacity of >600.000 m3/day and provides ~20% of the nation’s water supply.
At the other end, some customers are rather looking for more flexible (and movable) facilities and are building up their plants based on 20-40 feet storage containers (modular facilities) which together produce smaller volumes of around 2.000 m3/day but can be moved in case the source water quality decreases or according to need e.g. with multi-year droughts.
The CowaTech technology is envisioned to ultimately be used as:
initially, a pre-treatment process step in RO plants and thereby increasing the capacity and decreasing the operating costs of such existing facilities
next, to be used as the only desalination process step in new water facilities (modular)
