DEVELOPING AN AFFORDABLE, SCALABLE AND GREEN WATER DESALINATION TECHNOLOGY
IMAGINE IF WE COULD
TRANSFORM WATER TO TRANSFORM LIFE
Our why: the water scarcity challenge
By 2025, the UN expects that 14% of the world's population will encounter water scarcity, and by 2050, this could increase to 3 billion people.
At the same time, we are surrounded by an untapped water opportunity:
the oceans, seas and brackish water!
97.5% of the world's water resources is saline water, and almost 40% of the world's population live within a
100 km. range of a sea.
In support of UN's Sustainable Development Goal #6, we aspire to make water desalination affordable and scalable while leaving a low carbon footprint with our novel and innovative technology.
and its applications
Our desalination technology is based on a recyclable, organic compound (diamine), which captures salt (NaCl) in water 'like a sponge' when activated by insertion of CO2 to the water and with no other energy source required.
At present, our lead candidate can within minutes, in lab scale, ensure 89% salinity reduction in the first cycle of desalination, and 99.6% salinity reduction in two cycles. This is based on a starting sample salinity level of 35 g/L where drinking water quality (<0.6 g/L) is obtained after two cycles.
Reducing water salinity has various applications from e.g. producing potable water to industrial waste water treatment and brine handling.
Ongoing projects and outlook
Currently, CowaTech is pursuing two grant-funded development projects.
One is a project with the aim of developing a bottle-sized prototype (1-3 liters) for individuals or small groups in need of a desalination solution when either hiking, boating, or for emergency back-up situations.
The other is a project aiming at providing more comprehensive experimental data at larger-than-lab scale enabling an eco-efficiency evaluation of our technology as well as a tox assessment for industrial use.
Based on the project outcomes, matching partners and investors will be approached in second half of 2020.
