"The two EDI" is a "double mixed bed structure two EDI membrane heap. That an EDI pure water room to remove Sio2 type electronic grade mixed bed resin filling, the two EDI pure water room the TOC type of nuclear grade polishing mixed bed resin filled.
The important feature of the two EDI membrane heap is an EDI Sio2 high removal rate, two EDI high removal efficiency of organic carbon TOC. Its terminal resistivity 16-18.2MΩcm, TOC <4ppb, Sio2 <1ppb.
