The water treatment method for human has been quite a few years, and the physical method includes using various filter materials with different pore sizes, removing impurities in water by adsorption or blocking method, wherein the important adsorption method is to use activated carbon for adsorption, and the blocking method is to pass water through the filter materials to prevent the impurities with larger volume from passing through, so as to obtain cleaner water.
Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that separates solvent from solution using pressure differential as the driving force. The feed liquid on one side of the membrane is pressurized and when the pressure exceeds its osmotic pressure, the solvent will reverse permeate against the natural direction of permeation. Thereby obtaining a permeate solvent, i.e., permeate, on the low pressure side of the membrane; the high pressure side gives a concentrated solution, i.e. a concentrate. If the 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.
For reverse osmosis water treatment, water is pumped into a water storage tank with a higher position, the water level in the water storage tank is higher, the water flows under the action of gravity of the water, the water pressure is higher, the water enters a reverse osmosis filtering device, and the water is separated into fresh water and brine through the reverse osmosis filtering effect.
