A first in solar-powered mobile charging and water filtration for off-grid settings.
300 litres of water filtered per day
40 mobile phone charges per day
Access to offline digital services
Remote monitoring possible
In 2015, 71% of the global population (5.2 billion people) used a safely managed drinking-water service – that is, one located on premises, available when needed, and free from contamination. Currently 423 million people still take water from unprotected wells and springs. As inappropriately managed water services expose individuals to preventable health risks, we are developing a solution to improve the drinking water quality for existing community water sources.
Our Solar Water Alternative Purifier and Charging System (SWAPCY) is equipped with a 5 μm sediment filter able to remove sand, algae, rust and suspended particles. Furthermore, two integrated 0.1 μm antimicrobial ultrafiltration membranes remove aluminium, ammonia, iron, active chlorine, sulphates, nitrates, bacteria and coliform bacteria resulting in a total daily filtration capacity of 300 litres (2.2L per individual across 135 people). Other components include 8 USB mobile phone charging ports (charging 40 phones per day), LED lighting for operation at night, as well as the possibility to incorporate a Raspberry Pi system. We currently have two working units in operation in Rwanda.
