HB series modules

The product flow rate of the new type improved by about 1.4 times compared with the conventional type. A high-pressure, single-pass desalination process of new HB series modules with high recovery was successfuUy conducted for the first time at an RO test plant on the Red Sea at the conditions of more than 52% recovery (Kumano et al., 2003). 

Brine water flows on the periphery of the RO element passes through the narrow space between pressure vessel and supporting plate and flows to the brine port of the pressure vessel. The specification of the HB series modules are shown in Table 2.7. The product flow rate of the BOB module improved by about 1.5 times compared with the conventional type (Kumano, 2004).
