Water and Environment Related Activities
We promote the conservation of water environment to the world.
Japan is a country blessed with an abundance of clean water. Daiki-the predecessor of Daiki Axis-launched its water treatment business in Matsuyama City, Ehime Prefecture, which faces the Seto Inland Sea. Since developing the light and durable FRP (fiber-reinforced plastic) johkasous, Daiki has led Japan’s water treatment industry and continues to create many “industry’s firsts.” We have followed the path not only of providing our customers with safe water, but also toward becoming an “eco-creation and development company” that protects the environments that water runs through, and these efforts will continue as we head toward the future. One of our contributing successes to this end was the acquisition of the EcoMark certification from the Japan Environment Association for our 2013 Household XE johkasou. To support the building of a mutually comfortable relationship with our natural environment, we, Daiki Axis starts in Japan to work toward the conservation of water environment and promote it throughout the world.
Domestic Wastewater Products
The B Type : the Most Reliable Series Among Domestic Wastewater Products
Johkasou (Domestic Wastewater Treatment System): BA type, BAE type, BJ type , BJE type
Moving bed type Treats 1cbm or more water per day
  • Offers high-load and expeditious treatment, and easy maintenance.
  • Nitrogen can be removed through its anaerobic filter chamber.
  • Sludge can be stored in high concentration in the separation box. The sludge only needs to be drawn once every 6-12 months.
  • Comes in three styles and body types (capsule chamber, cylindrical chambers ofφ2170 andφ 2500) and this makes possible to meet various water quality criteria and installation space requirements.
  • Energy-saving blowers keep running costs low.
  • The most updated automated machinery ensures stable high-quality product anufacturing.
