6000 liter salt water desalination machines using reverse osmosis system and self clean system
The basic principles and characteristics of the reverse osmosis method:
1, Principle: A container is divided into two halves by a selective permeation
membrane. Pure water and brine are added simultaneously on both
sides of the membrane to make the liquid level on both sides of the
membrane as high. After a certain period of time, salt water will
occur. The liquid level on the side is rising, and the liquid level
on the pure water side is decreasing. This is due to the migration
of water molecules through the semipermeable membrane to the brine
side. This phenomenon is called infiltration.
2, Reverse osmosis membrane: a membrane that is selectively permeable to water or solution
If an appropriate pressure is applied to the concentrated solution,
the permeation can be stopped. The pressure when the penetration of
the dilute solution into the concentrated solution is stopped is
called the osmotic pressure.
3, Reverse osmosis device: reverse osmosis is to add a higher pressure than the natural
permeate on the side of the concentrated solution, reverse the
natural infiltration direction, and press the ions in the solution
to the other side of the semipermeable membrane, which is in normal
penetration with nature. The opposite is true
4, Reverse osmosis method: can remove more than 90% of soluble salts and more than 99% of
colloidal microorganisms and organic matter from water.
5, The advantages of equipment compared to other water treatment
methods:
No phase change, normal temperature operation, simple equipment,
high efficiency, less land occupation, convenient operation, less
energy consumption, wide adaptability, high degree of automation
and good effluent quality.
Safe operation of reverse osmosis desalination system
| Regularly test the SDI index | Excessive SDI can cause irreversible contamination of the membrane module and shorten the life of the module. |
| Control recovery | The recovery rate is too high. On the one hand, the components of the insoluble salt are more than the solubility product and the scale is formed. On the other hand, the flow rate of the concentrated water in the assembly is too low, and it is easy to cause concentration polarization to cause scaling, and is not conducive to the colloid in the water. , suspended matter, etc. are discharged. |
| Pay attention to pressure of the membrane module | The initial pressure difference of the membrane module is very small. If the pressure difference increases rapidly, it indicates that the membrane module is contaminated or fouled, and the cause must be identified and corrected. |
| Pay attention to water production and desalination rate | If the water production and desalination rate change significantly in a short period of time, it is necessary to check whether the pretreatment system is operating normally, such as whether the dosage is appropriate or not, and whether the filter is leaking sand. |
