CAPZ desalination , salt production and chemical industries. Climate change will change the future of salt industries in India and elsewhere due to unseasonal monsoon rains, flooding, increasing humidity, harsh working conditions for the labour, low and unsustainable wages, increasing demand for salt world wide for de-icing of roads. The price of salt in India is as low as Rs1200/Mt ($15/Mt) but the price of salt in the international market is as much as $170/Mt. Chemical manufacturers consume almost 80% of salt produced in India but they have to use elaborate purification process in order to use them in the production of Caustic soda and soda ash. When purifying solar evaporated salt and converting to into a purified 315 gpl concentration Sodium chloride brine their cost increases substantially to as much as $ 150/Mt. The increase in cost is about 10 times the cost of raw salt. Solar salt requires a large area of land, dry weather, low humidity and strong wind and long residence time, about 8-10 months. With increasing production of Chemicals, the usage of salt has increased substantially. It has created a huge supply demand gap increasing the price of salt. But the wages of labour remain the same in spite of harsh weather conditions, exploitation of women labour have created many social issues. We in CEWT are working hard to bring about a change by introducing our CAPZ desalination technology. CAPZ desalination technology generates purified 315 gpl concentrated Sodium chloride brine directly from sea water and also generate substantial amount of fresh drinking water. The future water demand world wide requires a substantial recovery of fresh water from seawater not just 40% . CAPZ is the only desalination technology in the world that separates salt in the form of readily usable brine and drinking water simultaneously making it an important and critical technology for drinking water as well as salt and Chemical industries in the future. It offers stability to the price of salt and chemicals derived from them. For example, critical metals like Aluminium which depends on the availability of Caustic soda cannot fix their price because of uncertainty and fluctuating price of salt and Caustic soda. Chemical industries are one of the most polluting industries in the world that generates hundreds of thousand of solid toxic wastes all over the world and such wastes are invariably dumped into the sea severely damaging the marine life and creating ecological problems. It is time Chemical industries adopt CAPZ desalination technology for a sustainable future! Thanks "The Hindu " for the following you tube video that highlights the problems faced by salt industry in India.
