Company Instruction:
Xi’an Xinshengtai (XST) Water Treatment Technology Co., Ltd.
(Formerly Xi’an Shengtaihuagong Science & Technology Co., Ltd.) was founded in 2003.
It’s an environmental friendly hi-tech company that specializes in research, production, and sale of water treatment equipment.
Since established, XST has finished thousands of water treatment projects, involving chemical industry, power plant desalination
water, electrodeionization ultra pure water, medical industry, aviation cleaning, food and beverage industry, municipal heating,
softened circulating water, living water purification, brackish water desalination, sea water desalination, industrial waste water
treatment, reclaimed water reuse, rural area drinking water project, and etc.
Xinshengtai Environmental Protection Industrial Park was built in 2011 in Xi’an-Xianyang New Area, which occupies 24,000 square meters. We now have 150 staff, with 50% of which have senior or advanced title.
And we established long term partnership with many universities and scientific research institutions in Xi’an.
Our experienced and well trained staff can provide first class one stop services from on site investigation, project design, business
negotiation, installation and adjustment, to after sales service.
Please just tell me your needs and we will do the rest for you.
SPECIFICATIONS:
*General Features
Permeate flow rate: 6,000 GPD (22.7 m3/day)
Nominal salt rejection: 99.75%
Effective membrane area: 370 ft2 (34.4 m2)
1. The stated product performance is based on data taken after 30 minutes of operation at the following
test conditions:
• 32,000 mg/L NaCl solution at 800 psig (5.5 MPa) applied pressure
• 8% recovery
• 77 oF (25 oC)
• pH 6.5–7.0
2. Boron rejection is 92.0% at pH 8.0 and 5 mg/L boron feed with the same test conditions as above.
3. Minimum salt rejection is 99.6%.
4. Permeate flow rate for each element may vary but will be no more than 15%.
5. All elements are vacuum sealed in a polyethylene bag containing 1.0% SBS (sodium bisulfite) solution and individually packaged in a cardboard box.
Membrane type: Thin-Film Composite
Membrane material: Polyamide (P A)

Design Guidelines for Various
Water Sources
· Wastewater Conventional (SDI < 5) 8–12 gfd
· Wastewater Pretreated by UF/MF (SDI < 3) 10–14 gfd
· Seawater, Open Intake (SDI < 5) 7–10 gfd
· Seawater, Beach Well (SDI < 3) 8–12 gfd
· Surface Water (SDI < 5) 12–16 gfd
· Surface Water (SDI < 3) 13–17 gfd
· Well water (SDI < 3) 13–17 gfd
· RO permeate (SDI < 1) 21–30 gfd
Saturation Limits
(Using Antiscalants)
· Langlier Saturation Index (LSI) <+1.5
· Stiff and Davis Saturation Index (SDSI) <+0.5
· CaSO4 230% saturation
· SrSO4 800% saturation
· BaSO4 6,000% saturation
· SiO2 100% saturation
The above saturation limits are typically accepted by proprietary antiscalant manufacturers. It is the user’s responsibility to ensure proper chemical(s) and concentration are dosed ahead of the membrane system to prevent scale formation anywhere within the membrane system. Membrane elements fouled
or damaged due to scale formation are not covered by the limited warranty
GENERAL HANDLING PROCEDURES
* Elements contained in the boxes must be kept dry at room temperature (7–32°C; 40–95°F) and should not be stored in direct sunlight. If the polyethylene bag is damaged, a new preservative solution (sodium bisulfite) must be added and air-tight sealed to prevent drying and biological growth.
* Permeate from the first hour of operation should be discarded to flush out the preservative solution.
*Elements should be immersed in a preservative solution during storage, shipping and system shutdowns to prevent biological growth and freezing. The standard storage solution contains 1% by weight sodium bisulfite or sodium metabisulfite (food grade). For short term storage (i.e. one week or less) 1% by weight sodium metabisulfite solution is adequate for preventing biological growth.
* Keep elements moist at all times after initial wetting.
* Avoid excessive pressure and flow spikes.
* Only use chemicals compatible with the membrane elements and components. Use of such chemicals may
void the element limited warranty.
*Permeate pressure must always be equal or less than the feed/concentrate pressure. Damage caused by permeate back pressure voids the element limited warranty.
