Toyobo double-element modules

Toyobo double-element modules, with many advantages, were developed in 1981. This module structure and flow pattern is shown in Figure 2.6. 

Conventional hollow-fiber RO module consisted of a single element inserted in one pressure vessel. However, economical and technical considerations demanded modules with a number of elements inserted in one pressure vessel. Toyobo successfully produced double-element modules on a commercial basis for the first time in 1979 and was followed by various types of double-element modules based on their flow path design. 

Toyobo double-element-type hollow-fiber RO modules (HM10255) are used for both Jeddah Phase I and Phase II plants. Figure 2.9 illustrates the schematic flow of the Jeddah 1 Phase II plant.
