Case Study

In San Antonio, we provided some restaurants the reverse osmosis systems designed for restaurants.

One example is Hero’s Ramen x Sushi. Have you ever been to Hero’s? You should feel that their drinking water is very delicious. Hero’s Ramen x Sushi serves RO water Seki Water provided and is using the water for their foods such as steamed rice and so on. Please try out drinking just their water!

Another restaurant is Nama Ramen. Nama Ramen has started using RO water since September 2018. The owner said “not only customers but also employees enjoy the RO water. Since water is very delicious, some employees bring their own bottles and take water.
