The Clara Pur uses solar thermal radiation to make drinking water out of salt water or untreated ground or surface water

Clara Pur main emphasis is on the development and sales of solar water treatment modules. The individual modules of CPs can be combined to more complex structures. On each day of sunshine, a single CP produces at least 10 litres of drinking water. It requires very little maintenance and operating costs are kept to a minimum, since it is supplied with solar energy. Production costs amounts to 0,0025 euros per litre. The Munich Patent Office granted Clara Pur GmbH a patent on the product.

Scarcity of drinking water • 2/3 of our planet are covered with salt water • The CP produces drinking water by means of solar sea water desalination • In the pipeline there are desalination facilities for 8 billion litres of drinking water Contaminated Groundwater • Over 100 million people, e.g. in Tanzania, India, Bangladesh and China, drink from wells with contaminated water • The CP purifies groundwater of many toxic substances like arsenic and fluoride • Polluted Surface Water • A vast number of people is forced to drink polluted surface or brackish water • 80% of all diseases are caused by contaminated water • Every year 5 million people die due to polluted water • The CP purifies water from nearly all dangerous substances The Distribution Problem • Remote, rural areas that are located off-grid need to be supplied with drinking water • In many cases water has to be transported over hundreds of kilometres, e.g. by ship to Indonesia • The water cannot be consumed immediately after transport, but has to be treated, e.g. by boiling it • The CP produces drinking water at the point of use, which solves the distribution problem
