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.

Our 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.
