This Series is specifically designed to maximize the benefits of hot water sanitization for industries relying on chemical free sanitization for product quality and/or industry compliance standard. Separation system sanitization protocol is per- formed via periodic exposure to temperature as high as 195°F (90°C) at minimum feed pressure to kill microorganisms by denaturation and coagula- tion of the proteins chains. The Duratherm HWS RO and HWS NF are suitable for separation systems purifying water at tem- perature up to 122°F (50°C) in low crossflow envi- ronment and no suspended solids. The Duratherm HWS RO HR and HWS UF can be selected for op- eration with feed stream temperature up to 158°F (70°C). This Series includes a variety of size 8”, 4” and 2.5” diameters. All element constructions include Du- rasan* Cage outer wrap, Polysulfone ATD and central tube.

Individual flow rate may vary +25%/-15%. Final permeate flow rate is subject to variations in the heat treat- ments. In most cases, the permeate flow rate after heat treatments will stabi- lize at 30-50 percent below the nominal flowrate before heat treatment. For a conservative design, consider a permeate flow reduction of 50%. 咨询：0571-28892801杭州道纳膜科技有限公司 Page 2 FS1270EN Model Active area ft2 (m2) Outer wrap Part number Duratherm HWS RO 2540 HR 25 (2.3) Cage 1263600 Duratherm HWS RO 4040 HR 88 (8.2) Cage 1263435 Duratherm HWS RO 8040 HR 355 (33.0) Cage 1263599 Duratherm HWS RO 2540 25 (2.3) Cage 1228430 Duratherm HWS RO 4040 85 (7.9) Cage 1228459 Duratherm HWS RO 8040 355 (33.0) Cage 1228481 Duratherm HWS NF 2540 HF 25 (2.3) Cage 1263452 Duratherm HWS NF 4040 HF 88 (8.2) Cage 1263437 Duratherm HWS NF 8040 HF 355 (33.0) Cage 1262377 Duratherm HWS UF 8040 HR 360 (33.4) Cage 1207315 Duratherm HWS UF 2540 HF 25 (2.3) Cage 1233601 Duratherm HWS UF 4040 HF 88 (8.2) Cage 1263698 Duratherm HWS UF 8040 HF 380 (35.3) Cage 1263602 Figure 1a: Element Dimensions Diagram (Female) Figure 1b: Element Dimensions Diagram (Male) Table 2: Dimensions and Weight Dimensions, inches (cm) Boxed Model1 A B2 C3 Weight lbs (kg) HWS 2540 Models 40.0 (101.6) 0.75 (1.90) OD 2.4 (6.1) 4 (1.8) HWS 4040 Models 40.0 (101.6) 0.75 (1.90) OD 3.9 (9.9) 9 (4.1) HWS 8040 Models 40.0 (101.6) 1.125 (2.86) 7.9 (20.1) 29 (13.2) 1 These elements are dried and bagged before shipping. 2 Internal diameter unless specified OD (outside diameter). 3 The element diameter (dimension C) is designed for optimum performance in GE Water & Process Technologies pressure vessels.

Feed pressure during sanitization should not exceed 40psi (275kPa) and the crossflow should not incur a pressure drop greater than 2psi (14kPa) per ele- ment. Heating rate to sanitizing temperature and cool down should not be faster than 5°C/minute. Maximum sanitization temperature is 90°C. Loss of permeate flow after repeated 90°C sanitization cycles It is almost impossible to exactly predict the per- centage of permeate flow rate lost from the high temperature sanitations, which among other fac- tors depends on: 1) Rate of temperature increase and decrease. 2) Presence of other species like organics, ionic and metallic compounds that could locally de- crease or increase the temperature at the sur- face of the membrane. 3) Feed flow rate and specifically the heat trans- fer rate to the membrane surface. 4) The thickness and geometry of the feed spacer used. At optimum conditions measured in controlled environment with deionized water, between 30% and 50% of the original permeate flow rate was lost before the element performance had stabi- lized after repeated heat treatments (over 90% of this flow reduction occurred during the first heat treatment). With the loss of permeate flow rate, the salt rejection increases. The rate of cooling and heating was not more than 5°C per minute, and the differential pressure drop per element did not exceed 2 psi. Pilot testing based on the criteria noted above will give the best operating parameters for any spe- cific application.
