Seawater desalination is ‘the processing of seawater in fresh water’.
The ‘reverse osmosis membrane method’ endorsed by our company is a desalination technology known as ‘reverse osmosis membrane’ which has been used in Japan for over 30 years.
Seawater desalination technology keeps improving every day and is continuing to contribute to our world.
Our company has acquired this technology and actively attends training sessions and lectures by major water treatment companies in order to offer even newer and more unique water treatment technologies.
As seawater desalination professionals, we are working together with technological advancements.
Water and air are indispensable to all forms of life.
Our company engages in maintenance work in order to ensure the stable supply of clean air and safe and secure water.
1. Operation/maintenance management work
Regular operation management and equipment maintenance inspections are necessary for the mechanical equipment being operated at water purification and treatment plants.
Our company has an understanding of the daily operational state of this mechanical equipment and takes measures to ensure that unforeseen trouble does not occur. We also offer suggestions on budgets and timelines for updates to and exchanges of machinery.
2. Maintenance work
Occasionally, trouble can occur with regards to equipment that is currently in operation as a result of deterioration over time.
The rotary machines used in water purification and treatment plants wear out, so we carry out maintenance by means of disassembling and repairing.
3. Planning improvements to treatment methods
Raw water, which is the source of drinking water, is dam water, river water, and well water which has accumulated due to rain. The content of different components and substances within this raw water change under various natural environments.
Our company investigates and clarifies the causes for this and makes plans for water processing methods which allow us to offer a safe, secure, and stable supply of water.
We are engaged in the design, manufacturing, and installation of plants and equipment related to water supply and environmental businesses.
We make the optimal proposal based on geographical conditions, raw water composition, and water intake.
