It was sure that we had been rich in water as a gift of nature for a long time. We have regarded water as one of the closest resources to human life, too. So, we didn&＃39;t need to care about the quantity & quality of water in those times when the uses of water in industry was not so high.But the demand for water and environmental pollution became one of the most important social issue in the process of rapid industrialization. Moreover, water is getting more important for stable working condition in production line. And the environmental pollution which decides the quality of human life is worrying us more.Water is different in everywhere and always changing. That&＃39;s the reason why we established HANSU Ltd. in cooperation whth KURITA WATER Industries CO.,Ltd, under the business idea "OUR WATER BY OUR TECHNOLOGY" in 1974.For 24 years after that, we have taken the initiative in developing and spreading in water treatment field. Now we are in charge of the water treatment for over 1,000 production lines within the country. And we are supporting them through the development of chemicals, technologies and the top management system concerned with water treatment, too. We first founded a general research center in this field and tried to meet the customer&＃39;s demand with it. With these efforts, we got credit for it and was awarded grand prize of minor enterprises. We approached one step forward to customer satisfaction by aquiring ISO 9002 certificate in march, 1996 and ISO 14001 certificate in October, 1997, too. Not to content with the current situation, we promise that we&＃39;ll make more efforts and try to pay back customer&＃39;s love by solving the present problems one by one.Thank you very much.
