Background technique
Purified water process is that surface water or other water sources are entered by raw water pump by filter, then by high-pressure pump pressurization
In reverse osmosis membrane, under pressure, semi-permeable membrane is known as to the selective film of the substance of transmission, can only generally be penetrated
Solvent and ideal semi-permeable membrane cannot be referred to as through the film of solute.When the weak solution (such as fresh water) of same volume and dense molten
When liquid (such as salt water) is respectively placed in the two sides of semi-permeable membrane, the solvent in weak solution will be naturally across semi-permeable membrane and spontaneously to dense
The flowing of solution side, this phenomenon are known as permeating.When infiltration reaches balance, the liquid level of concentrated solution side can be than the liquid level of weak solution
It is higher by certain altitude, that is, forms a pressure difference, this pressure difference is osmotic pressure.The size of osmotic pressure depends on the inherency of solution
Matter, i.e., with the type of concentrated solution, concentration and temperature in relation to and with the property of semi-permeable membrane it is unrelated.If applying one in concentrated solution side
Greater than osmotic pressure pressure when, the flow direction of solvent will be contrary with original infiltration, starts from concentrated solution to weak solution
Side flowing, this process are referred to as reverse osmosis.Reverse osmosis is a kind of reversed travel motion of infiltration, is one kind in pressure-driven
Under, the separation method for separating solute and the solvent in solution is acted on by means of the selective retention of semi-permeable membrane, it has been widely used

Mainly under the action of DC electric field, by dielectric ion in the water of partition displacement occurs for deionization (EDI) system,
Effect is penetrated come a kind of water treatment technology of the science purified to water quality to the selection of ion using exchange membrane.Electric dialyzator
A pair of electrodes between, be usually alternately arranged by cavity block, anode membrane and partition (first, second) multiple groups, constitute dense room and light room (i.e. sun from
The permeable anode membrane of son, anion can pass through cavity block).Cation migrates through anode membrane to cathode in light room water, by the yin in dense room
Film retention;Anion migrates cavity block to positive extreme direction in water, is retained by the anode membrane in dense room, passes through the water intermediate ion of light room in this way
Number gradually decreases, and becomes fresh water, and in the water of dense room, since the zwitterion of dense room is constantly poured into, dielectric ion concentration is not
It is disconnected to increase, and become concentrated water, to achieve the purpose that desalination, purification, concentration or purification.
Novel pure water desalting plant is composed of reverse osmosis with electrodialysis (EDI), and recent years is pure using relatively broad
The core apparatus for changing wetting system is combined the unit with electrodialysis (EDI) using reverse osmosis in water purification equipment, system can be improved
Standby purified water water quality out, keeps the stability of effluent quality more preferable, using Automatic Control, modularization preparation.It is reverse osmosis with it is electric
The application of dialysis (EDI) combination unit, provides the foundation guarantees to the effluent quality of purified water preparation system, meanwhile, it is capable to expire
The water demand of sufficient pharmaceutical industry.
Currently, in the prior art reverse osmosis larger with electrodialysis (EDI) combination unit volume, occupied area is larger, very
Ship of the hardly possible for navigation.Therefore it is badly in need of a kind of purifying water installations on ship.
