Product Description
Reverse osmosis equipment is to pass the raw water through fine filter, granular activated carbon filter, compressed activated carbon filter, etc., and then pressurize it through pump, with an aperture of 1 / 10000 μ M (equivalent to 1 / 6000 of the size of E. coli and 1 / 300 of the size of virus), the reverse osmosis membrane (RO membrane) separates the high concentration water into very low concentration water (i.e. purified water) and higher concentration water. The low concentration water is used, and the high concentration water is discharged or reused. At the same time, all impurities mixed into the water such as industrial pollutants, heavy metals, bacteria and viruses are isolated, so as to meet the physical and chemical indexes and health standards specified for drinking, It produces clear and pure water, which is the best choice for human body to supplement high-quality water in time Because the purity of water produced by RO reverse osmosis technology is the highest among all water production technologies mastered by human beings in the manufacturing of drinking water, and the cleanliness is almost 100%, so people call this water production machine reverse osmosis purified water machine. Of course, some pure water manufacturing technologies with higher purity (such as EDI, polishing mixed bed, etc.) are not suitable for drinking water production.
Purified water equipment is simply the equipment for producing purified water. And purified water is widely used by us: domestic drinking, chemical industry, medical treatment, breeding, planting, food, beverage and so on.
Reverse osmosis equipment applies membrane separation technology, which can effectively remove charged ions, inorganic substances, colloidal particles, bacteria and organic substances in water. It is the best equipment in the process of high-purity water preparation, brackish water desalination and wastewater treatment. It is widely used in electronics, medicine, food, light textile, chemical industry, power generation and other fields.
Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that takes the pressure difference as the driving force to separate the solvent from the solution. Apply pressure to the feed liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will reverse osmosis against the direction of natural penetration. Thus, the permeable solvent, i.e. permeate, is obtained on the low-pressure side of the membrane; The concentrated solution, i.e. concentrated solution, is obtained on the high-pressure side. If seawater is treated by reverse osmosis, fresh water is obtained on the low-pressure side of the membrane and brine is obtained on the high-pressure side.
During reverse osmosis, the penetration rate of solvent, i.e. liquid flow energy N, is:
N=Kh( Δ p- Δ π)
Where KH is the hydraulic permeability coefficient, which increases slightly with the increase of temperature; Δ P is the static pressure difference on both sides of the membrane; Δ π is the osmotic pressure difference of the solution on both sides of the membrane. The osmotic pressure π of dilute solution is:
π=iCRT
Where I is the number of ions generated by ionization of solute molecules; C is the molar concentration of solute; R is the molar gas constant; T is the absolute temperature.
Reverse osmosis usually uses asymmetric membrane and composite membrane. The equipment used in reverse osmosis is mainly hollow fiber or roll membrane separation equipment.
Reverse osmosis membrane can intercept various inorganic ions, colloidal substances and macromolecular solutes in water, so as to obtain purified water. It can also be used for preconcentration of macromolecular organic solution. Due to its simple process and low energy consumption, reverse osmosis has developed rapidly in recent 20 years. It has been widely used in seawater and brackish water (see brine) desalination, boiler water softening and wastewater treatment, and combined with ion exchange to produce high-purity water. Its application scope is expanding and has been used in the concentration of dairy products and fruit juices, as well as the separation and concentration of biochemical and biological agents.
