高阻止率スパイラル型ROエレメントCPA7–LDの開発

抄録

Reverse osmosis (RO) process has been developed for water purification and energy saving of some kinds of industrial factories and desalination plants. Because of the change of water resource, some customers tend to demand high rejection type RO elements. CPA7–LD element was developed under the concept of higher rejection for some kinds of solutes. This element shows higher solute rejection, especially silica and can be applied for the industrial waste water recovery and boiler makeup water for power generation.
