Sustainable long-term solutions are critical in a changing world of water treatment; the quality of surface water is extremely challenging and it is crucial that all pollutants are removed in order to make the water fit for human consumption and avoid waterborne diseases.
A growing problem in the pollution of surface water is salt and pollutants such as drug residues and pesticides. Added to this are the chemical residues of what we use to disinfect and purify water such as chlorine-by products and fluoride, both of which are carcinogenic.
Global water supplies are becoming more and more constrained due to climate change and global warming, resulting in scientists turning more and more to searching for various means of transforming saltwater, wastewater effluent, and polluted river water into potable drinking water.
While the development, adoption and use of new water treatment technology is still a crucial challenge to improving safe water supply, expanding urbanisation means that there is insufficient space for existing technology, which leads the way for more compact technology.
There is also a growing need for more environmentally friendly and sustainable technology, which means that it is crucial that we develop and implement long-term, reliable, cost-effective solutions that have lower environmental impact.
Technology development that is reliable, sustainable, compact and efficient is the highest priority for all countries, and the race is on to develop technology that can meet all these requirements.
While there are many new and innovative ideas on the market and many countries are turning to desalination as a solution, removing the salt from sea water requires huge desalination plants and the process is rather expensive.
There are many scientists and researchers at various universities across the globe that are working on more innovative ideas, including atmospheric water generation systems, fog harvesting technologies, shock electro dialysis, and new membrane technology nano filters.
There are many more projects on the horizon and we hope that in the near future one of them will go a long way towards solving the global water crisis.
