As a comprehensive water service provider, Hitachi delivers optimized and streamlined solutions for water supply businesses utilizing IoT.
It has been said that over 40% of the global population will face serious water shortages in 2050.*1 To respond to the increasing global demand for water, Hitachi will further develop our technologies based on our abundant experience and achievement to contribute improving the global water environment.
Hitachi has been developing and delivering not only equipment and appliances, such as highly efficient pumps and inverters, but also water distribution control systems capable of contributing to the optimization of energy consumption by appropriately controlling the pressure (discharge pressure) from pumps.
As a comprehensive water service provider, Hitachi delivers optimized and streamlined solutions for water supply businesses utilizing IoT, including water and sewage systems and seawater desalination plants. Hitachi will continue contributing to the improvement of the global water environment by grasping growing customer needs and problems as well as proactively developing technologies.
Utilize treated sewage as dilution water for desalination, lowering the salinity of the seawater, which in turn lowers the pump pressure required for the desalination process, achieving an energy saving of approximately 40%*2.
Predict and control in real time the airflow of the ventilator to the biological reaction tanks that treat sewage, thereby reducing the airflow of the ventilator by approximately 38% and electric power consumption by approximately 27%.
The use of appropriate discharge pressure to operate the water transmission and distribution pump, which accounts for 80-90% of electric power usage of water service providers in Japan, reduces electric power consumption by approximately 4%.
