Hitachi's Social Innovation Business


Water is an essential natural resource on which all life depends. Some 70% of the Earth's surface is covered with water, but only about 0.01% of that represents readily potable water.
To date, Hitachi has delivered some 550 water treatment plants, 2,800 sewage treatment facilities, and 900 monitoring and control systems to locations across Japan. Hitachi offers a diverse range of technologies for water treatment systems and their control and operation. By integrating our advanced IT technologies and store of know-how, we create sophisticated intelligent water systems that are improving water infrastructures around the world.

As an early provider of commercial seawater desalination systems, Hitachi has delivered systems to customers in Japan and overseas. We're currently developing technologies to be necessary to desalinate deep ocean water for highly cost-effective applications (e.g., air-conditioning systems that use desalinated water as a cold energy source).

Water treatment: Ensuring a safe and reliable water supply

Working with our group companies, Hitachi develops a comprehensive range of water treatment technologies and gains know-how. We provide the reliable equipment needed, trouble-free water supply at all stages. They are ranging from water intake to water transmission, treatment, distribution, supply, and related instrumentation. The capacity covering full spectrum of equipment is Hitachi's major strengths.

Sewage water recycling: Making effective use of limited water resources

Hitachi proposes various sewage water recycling systems designed for specific applications, including Membrane bioreactor system. Our systems don't simply treat sewage water for safe discharge; they also draw on advanced processing to recycle sewage water to a standard that allows for its use in watering trees and plants and other applications such as toilet water and industrial water.

Industrial wastewater treatment: Strengthening the industrial water infrastructure

Recently, Hitachi has been developing new advanced technologies to meet diverse industrial wastewater treatment needs. We offer a wide range of solutions to the issues above like process wastewater generated by factories and plants. These include physiochemical, biological, membrane, crystallization, and sludge processing systems, as well as pure/ultrapure water production systems.

Information and control systems: Efficient management of water infrastructure

Hitachi offers information and control systems that enable us to manage broad-ranging data on a real time basic, such as the operating status of water/sewage treatment/water recycling systems and water transmission/distribution rates in individual processes. The information and control systems provide optimization control based on this data to maximize the overall cost-benefit of water circulation systems.

Sewage treatment: Improving and maintaining the water infrastructure

Hitachi is highly experienced in the area of sewage treatment—a field requiring a wide range of fundamental technologies—to provide an extensive lineup of sewage treatment systems. These include grit tank facilities, systems that improve combined sewer systems, advanced treatment systems, sludge treatment equipment, and deodorization equipment.
