[Case Study of Emergency Water Purification System Implementation] Factory <Business Continuity Plan / Community Contribution>

Operating with an emergency generator during disasters! Introducing a case study of a reverse osmosis water purification system.

We would like to introduce a case of the installation of an "emergency water purification system" at a factory. This system was set up to secure drinking water for 1,100 employees during a disaster. It uses pool water as the water source and consists of a water pump, reverse osmosis water purification unit, and sterilizer that can be operated by a generator during emergencies. Normally, it is stored within the disaster prevention headquarters and can be operated using an emergency generator during a disaster. The reverse osmosis water purification unit has self-supply capabilities using the fire water tank located under the floor of the disaster prevention headquarters as the water source. [Case Overview] ■ Client: Factory ■ Project: Installation to secure drinking water for 1,100 employees during a disaster ■ Model: WP-3000SOS-II (Reverse Osmosis Water Purification Unit) ■ Source Water: Fire Water *For more details, please refer to the related links or feel free to contact us.
