GreenLeaf Filter has been continuously evaluated for its stable operation
DB project for expansion of the Water Treatment Plant capacity within the same area of the existing Plant using the same sand filtration method
DB project for which a water treatment company acts as a representative of the Joint Venture, the first domestic project
A water treatment company acts as a representative company of the entire JV and promises reliable construction work.
Consideration of maintenance and management
The flow had to be the same as the existing one considering the maintenance and manageability of the existing water treatment plant to be operated simultaneously.
In particular, with regard to the filtration method, which is the core of water treatment, we proposed and adopted Greenleaf Filter, which was the same type & shape as the existing one. Moreover, additional function of cryptosporidium counter measure was also adopted.
Build water treatment facility by integrating mechanical and electrical equipment
Our scope was full package for not only mechanical equipment but also electrical equipment.
Especially with regard to electrical equipment, it was designed & installed with excellent maintainability and necessary & sufficient functionality by our experienced electrical engineers familiar with water treatment.
