Hitachi Infrastructure Systems (Asia) Pte. Ltd.

Environmental Systems

We provide total solutions – engineering, procurement, construction, operation and maintenance – for domestic and industrial water treatment and recycling, as well as sewage and industrial waster water treatment plants. We use the latest biological and membrane systems and processing technology to deliver highly efficient and reliable results, and at the same time contribute to the preservation of water environments.

Drinking water treatment systems

Drinking water treatment systems

Drinking water supply system is extremely important for everyday life. We are extensively experienced in and have a history of working with raw water intakes, transmission, water distribution and supply facilities, various chemical dosing, power receiving facility, instrumentation and SCADA system.

Sewage treatment systems

There are various needs in the sewage treatment field that change based on the environment and lifestyles, such as countermeasures against flooding, preservation of public water quality and re-use of water. We are a plant engineering and construction company that offer total solutions for water treatment. We develop systems and products necessary for these as well as provide services of construction, maintenance and operation. We contribute to the preservation of water environments with our leading technologies which are saving energy, saving power and saving space.

Sewage Treatment Systems (Pre-treatment/water treatment facilities)

Sewage Treatment Systems (Pre-treatment/water treatment facilities)

  • Pre-treatment facilities are that removes sand and screenings contaminants in the waste water inflow. We provide sand removal and screenings removal systems based on the installation conditions and purpose of use.
  • Water treatment facility creates clear treated water by biological treatment process with activated sludge and further settling and separation process. We provide various reaction tanks, sedimentation tanks and disinfection systems to suit the treatment method.

Sewage Treatment Systems (Sludge treatment facilities/others)

Sewage Treatment Systems ( Sludge treatment facilities/others )

  • Sludge treatment facilities stabilize and reduce the volume of generated sludge in water treatment facility. We provide various systems such as thickening, digestion, dewatering, drying and incineration systems.
  • Small-scale water treatment systems are appropriate for small-scale districts with a small population. We provide various simple systems that make maintenance easy.

Industrial Water Treatment Systems

Industrial Water Treatment Systems

We provide many kinds of water systems suitable for industrial water, pure water and waste water, in various industrial fields. We can provide our technologies with experience to help you plan both single device and water treatment plants, from design to construction and maintenance.

Introduction to overseas business

Introduction to overseas business

We have a lot of experiences as a total engineering and construction of drinking water, sewage and industrial waste water treatment system with operations in Japan and overseas.

In recent years, we have expanded our overseas sales of submerged membrane bioreactor system (MBR) and seawater reverse osmosis desalination system (RO) that use membrane treatment technology, and we have begun to enter the water recycling business using our systems.
