The SMART Feasibility project enabled us to produce a working prototype which proved that our technology can produce distilled water quicker and more energy efficiently than traditional distillation devices. This prototype technology is the basis for a future commercially viable product.
Water purification is a major issue for the future with 99.993% of the world's water being undrinkable. Pressures on fresh water supplies have become and continue to be greater as the world's population increases and requires more to survive.
Increasingly more use will have to be made of less directly potable sources of water, such as that which may be contaminated, brackish or otherwise deemed of previously marginal value. Moreover, quality in domestic mains supplies may deteriorate because of such factors as drought, contamination (such as by plastics and micro-plastics as these contaminate the water supply) ageing infrastructure and inability to cope with future demand. Many contaminants such as viruses, hormones, micro-plastics, heavy metals etc are not fully removed by filters and reverse osmosis machines.
Distillation provides one solution to this problem and distilled water is also used in large quantities in a variety of different industries within the chemical and biological field where highly purified water is essential. However previous distillation solutions in the market are outdated and have tended to be large, unwieldy, uneconomical and suitable only for large scale supplies, such as for an entire town.
The Clean Water Designs (CWD) technology solves this problem by developing a low-energy, high-speed water distillation device capable of producing pure distilled water free from all contaminants, regardless of the piped source water quality.
The patent pending technology, miniaturises the industrial process of Vapour Compression Distillation as well as recycling the energy used in the process making the device highly energy efficient. In designing the system we have come across several challenges and developed unique methods of speeding up and improving the energy efficiency of traditional distillation methods.
The technology gives us the opportunity to provide pure water in the kitchen for drinking when mixed with mineral cartridges. A key expert has described the system as an essential step to allowing Point Of Use water purification in target areas where piped water cannot be guaranteed as clean.
Goals of the SMART Grant project
Key Activities
For each of the challenges listed above, significant testing and computer modelling will be required as well as implementing advanced CNC manufacturing methods. Multiple prototypes will be required for testing,data recording and system improvement.
The final prototype must fit together in a continuously running system so further models and simulations must be completed to achieve this.
Multiple separate component experiments will need to be conducted until we have each component working efficiently and safely on their own and then merge them together into one fully functioning system.
