FIGURE 9.9 HYDRAcap 40, 60, and Max 80 ultrafiltration (UF) membrane modules. 9.7.3 Hydranautics (Nitto-Denko)
This membrane manufacturer offers pretreatment membranes which are low-pressure UF modules (see Fig. 9.9) that have found application at several large seawater desalination plants such as the 90,000 m3/day (24 MGD) Kindasa SWRO desalination plant in Saudi Ara- bia and the 96,000 m3/day (25 MGD) Fukuoka desalination plant in Japan. HYDRAcap 60 is the Hydranautics UF membrane module that has been used most widely to date.
In 2011, Hydranautics has introduced a new UF membrane of over three times higher surface area (105 m2 vs. 30 m2) and productivity than the baseline HYDRAcap 60 modeldthe HYDRAcap MAX 80. This membrane is made of more durable material, PVDF, and can handle water of very high turbidity (up to 80 NTU). The new membrane module has a
