Sustainable water resources management is one of our biggest concerns for the future. Environmental regulations are getting stronger, strive to lower our water consumption with an increasing cost of make-up water for the systems and process, and for the discharge treatments. Water reclamation is a priority of Kurita’s Corporate social responsibility for sharing value with our customers. Kurita proposes to combine all its expertise in cooling water treatments, equipment, and monitoring with remote control. Through patented technologies, Kurita’s blowdown recovery system leads to stable operation, reduction of running costs and better performance of the cooling system without investment for the user.

Water Scarcity
• By 2050 one in four people is likely
to live in a country facing either
chronic or recurring shortages of
fresh water.
(Source: The United Nations 2018)
• Global Water Demand is projected
to increase by 55% due to growing
demand from manufacturing,
thermal electricity generation and
domestic use.
