The composition of the reverse osmosis membrane housings are mainly two pipes with materials allowed to enter and leave, and the parts at both ends of the main body of the pipe are mainly used to flow out through the liquid.
Note during installation
1. Fix the bracket completely.
2. The pressure vessel is horizontally supported and reliably fixed according to the span (S) recommended by the manufacturer.
Note:
a. Ensure horizontal support and reliable fixation according to the span (S) recommended by the manufacturer.
b. Make sure to use the saddle and strap flexible fixing pressure vessel provided by the manufacturer.
c. It is forbidden to make any rigid fixation and connection to the pressure vessel.
3. Clean all the components of the end plate and the inner surface of the pressure vessel (strong acid and alkaline solutions are prohibited, and water or neutral solutions are recommended).
4. Apply appropriate lubricant to the seal ring surface and the sealing area on the inner surface of the pressure vessel (glycerin is recommended).
5. Put the thrust ring into the pressure vessel, and then install the concentrated water end plate.
FRP Membrane Housing
6. Push the membrane element into the pressure vessel one by one, and connect the adapter to the water purification outlet of the membrane element.
Note: Ensure sufficient assembly space to provide sufficient space for the installation of pressure vessels and membrane elements. Generally, the membrane elements are pushed in from the raw water side and pushed out from the concentrated water side when replacing.
7. Install the end plate of the raw water end into the pressure vessel to connect the adapter and the purified water outlet of the membrane element.
Note: Use a rubber mallet to strike the support end plate evenly until the baffle plate fits into the slot on the end face of the container.
8. Install the four-flap snap ring into the card slot, then install the security ring, and assemble the hexagonal bolt to fix it tightly.
9. Tighten the tube plug.
10. Connect the piping.
Note:
a. Ensure that there is room for flexibility in the pressure vessel's fixing and piping connections to accommodate the effects of radial and lateral changes in pressure vessels under pressure or temperature.
b. Make sure that the piping is freely docked with the original / concentrated water port of the side-connected pressure vessel and maintain concentricity.
c. It is forbidden to bear the weight of the piping by the pressure vessel.
Instructions and maintenance requirements
To ensure the long-term and safe operation of the fiberglass membrane housings, please observe the following regulations and recommendations.
1. The cold and hot shrinkage expansion rate of glass fiber reinforced plastic membrane housing is small. Please observe the rated design pressure index during use, and use it within the allowable value range. Prolonged overpressure operation is strictly prohibited.
2. The operating temperature of FRP membrane housings is generally within 7 ℃ -49 ℃. It is strictly forbidden to work under the temperature range.
3. The back pressure of the purified water outlet at the two ends must not exceed 125PSI.
4. Strictly abide by the pressure level of each medium, such as clean water, sewage, seawater, etc., if using special medium water, please contact the company in advance to avoid accidents.
5. When the system is working or there is pressure in the membrane housing, it is strictly prohibited to knock, disassemble or move the membrane housing. The surrounding vibration source environment must be strictly controlled.
6. The upper part of the membrane housing cannot be used as a load-bearing body to exert pressure and gravity, nor can it exert pressure on the corresponding parts of the membrane housing.
7. Cleaning. In order to ensure that the inner surface of the reverse osmosis membrane housing is clean, please choose a neutral cleaning solution for cleaning. Do not use concentrated hydrochloric acid, concentrated sulfuric acid, etc. as cleaning liquid.
