Hitachi Industrial Water Treatment Equipment


MBR-RO systems with abundant track records world wide.


In Maldives, Hitachi’s RO system is producing 17 million liters (4.5 million gallons) of drinking water per day.


In Dubai, Hitachi has supplied the integrated compact MBR and RO system for the water recycling system to Burj Khalifa.


Hitachi offers advanced Water Treatment Equipment such as RO (Reverse Osmosis) System and MBR (Membrane Bio Reactor) System for desalinating seawater, purifying brackish water and recycling wastewater in different capacities to suit the various requirements of our customers. Hitachi’s RO system and MBR system are with abundant track records. We have delivered over 500 units to more than 20 countries for 130 projects at competitive cost with high quality. Please find the client list. (http://www.hitachi-aqt.com/company/client-list.html).

Hitachi’s Water Business Example: Water treatment in Maldives
In 2010, the Hitachi has acquired 20% of the shares in Malé Water and Sewerage Company (MWSC) Pvt. Ltd., which supplies 4,700 gallons per day drinking water to 7 islands (150,000 peoples). Since then, Hitachi has been involved in its operations and has helped to improve operations in water and sewage treatment in the Maldives.

Hitachi's Water Business Example: Water recycling in Dubai, Burj Khalifa
Hitachi has supplied the integrated compact MBR and RO system for the water recycling system to Burj Khalifa, the world’s tallest building in Dubai, UAE. The treated water is recycled for water works. Hitachi also provides the operation and maintenance services.

Besides, Hitachi offers an 40% energy-saving, low-cost and minimal environmental impact seawater desalination system by integrating sewage treatment processes (RemixWater) and Comprehensive immobilizing nitrogen removal process (PEGASUS) with stable efficiency even at low temperature. Please find the below chart for the summary of Hitachi’s advanced water treatment technologies.

Hitachi’s water treatment technologies

Technologies Descriptions Applications/Industries
RO system
MBR System

RO(Reverse Osmosis) system is mainly for desalinating seawater, purifying brackish water and recycling wastewater.
MBR(Membrane Bio-reactor) system is a process that combines a membrane ultra / micro filtration process and activated sludge process widely used in wastewater reclamation applications.

Hitachi has delivered over 500 units to more than 20 countries for 130 projects at competitive cost with high quality.

For creating Potable and Non-Potable Water.

Private (Industrial, hotel, Irrigation,
Injection)
Public (Government, Municipality)

RemixWater

RemixWater is a process which integrates desalination system and sewage treatment system.

The features are;
Large Energy Saving Effect:
Lower Saline Concentration by mixing the treated waste water with sea water in the mixing tank which enable to reduce UF, RO process and Pump Pressure when compared to the conventional desalination.
Lower CAPEX and OPEX:
Above mentioned energy saving also contribute to lower CAPEX (Equipment & Construction costs) and OPEX (Electricity, Chemicals, Membrane and Maintenance costs)
Minimal Environmental Impact:
Discharged salinity is the same as of sea water(3.5%).

Those features are proven through the pilot project for Kita Kyushu Water Plaza funded by NEDO – Japan New Energy Development Organization for 3 years (December 2010 – November 2013).

For creating Potable and Non-Potable Water.

Private (Industrial, hotel, Irrigation,
Injection)
Public (Government, Municipality)

PEGASUS

PEGASUS is an advanced sewage treatment process that promotes nitrification and uses inclusive immobilization supports. with stable efficiency and its unique feature is as follows.

  • Simultaneous BOD / nitrogen treatment is
    possible with a residence period of 6-8 hours
  • Nitrogen removal efficiency is stable, even at low
    temperatures
  • Nitrogen removal efficiency is stable, even when
    combined with simultaneous coagulation methods

For removing Nitrogen.
