G2O’s graphene coatings on water treatment membranes reduce energy costs and extend service lifetime
Water is vital for life, for food production, industrial processes, hygiene etc. Currently the global economy uses about 2,600 cubic km of water per year and this is increasing rapidly. The World Economic Forum predicts that the gap between freshwater demand and supply will be about 40% globally by 2030 if ‘business as usual’ continues. According to the World Bank, 80 countries currently have water shortages that threaten human health and economic activities, while 70% of the world’s freshwater use is for agriculture. Some 800 million people live below UNEP’s water stress threshold (when annual water supplies drop below 1,700m3 per person) and by 2025 this number will rise to three billion. Already, there is competition and local conflict for available clean water.
The costs of recycling polluted water will rise. In Europe, 53% of transported surface water and groundwater is used by industry, 26% for agriculture and 19% for domestic purposes. Many companies rely heavily on water and access to water is critical for their products or services. Water use in agriculture and industry supply chains is often not factored into the cost of production. The production of 1kg of plastic uses about 185 litres of water, a pair of jeans 11,000 litres and a car 400,000 litres.
G2O Water Technologies applies graphene coatings to waste water, chemical filtration and reverse osmosis membranes which increase throughput, reduce fouling and save energy.
