Today, with an increasing emphasis on health, more and more people are beginning to pay attention to drinking water health and water usage. However, due to the abundance of impurities and scale in general water quality, it can pose a threat to the body and easily lead to the formation of stones and other conditions. The water purified by the pure water equipment is very suitable for drinking. It can promote the balance of water-based electrolytes in the body, accelerate the transformation of customs and practices, and at the same time ensure the water supply for food, beverages, hospitals and other industrial and daily life. During the operation of the equipment, it is necessary to pay attention to the regular replacement of accessories, reverse osmosis membranes, filter elements, water treatment filter materials, etc., to ensure the service life of the equipment and the quality of the effluent.

I.System composition

　　Pre-treatment

　　It generally includes raw water pumps, dosing equipment, quartz sand filters, activated carbon filters, precision filters, etc. Its primary effect is to reduce the pollution index and residual chlorine and other impurities of the raw water, meeting the feed water requirements for reverse osmosis. The equipment configuration of the pretreatment system should be determined according to the specific conditions of the raw water.

　　Reverse osmosis host

　　The primary components include multi-stage high-pressure pumps, reverse osmosis membrane elements, and membrane housings(Pressure vessel)It is composed of brackets, etc. Its primary effect is to remove impurities from the water and make the effluent meet the application requirements.

　　Post-processing

　　It is an additional equipment added when reverse osmosis fails to meet the water output requirements. The primary ones include anion beds, cation beds, mixed beds, and ultrafiltration.EDIAnd one or more of the devices in between. The post-treatment system can improve the water quality of the reverse osmosis effluent to meet the application requirements.

　　"Clean"

　　It is primarily composed of a cleaning water tank, a cleaning water pump and a precision filter. When the reverse osmosis system is contaminated and the effluent target fails to meet the requirements, it is necessary to clean the reverse osmosis system to restore its effectiveness.

　　Chemical cleaning of reverse osmosis membranes

　　Under normal working conditions, reverse osmosis membranes may also be contaminated by inorganic scale, colloids, microorganisms, metal oxides, etc. The accumulation of these substances on the membrane surface can lead to a decrease in the output or desalination rate of the reverse osmosis equipment for clear water, an increase in pressure difference, and even cause irreversible damage to the membrane. Therefore, in order to restore excellent water permeability and desalination performance, chemical cleaning of the membrane is required.

　　Electrical control

　　It is used to control the normal operation of the entire reverse osmosis system. Including instrument panels, control panels, various electrical protections, electrical control cabinets, etc.

Ii.Reverse Osmosis Pure Water Equipment - Accessory Product Introduction

　　Raw water tank

　　It stores raw water and is used to accumulate large sand particles and other accumulable substances in the water. Jointly buffer the impact of unstable water pressure in the raw water pipe on the water treatment system.(The response of pressure sensing caused by too low or too high water pressure).

　　Raw water pump

　　Stabilize the water supply pressure of the system and the water supply volume.

　　Multi-media filter

　　The primary purpose of using a filter with multiple filtration layers is to remove particles such as sand, rust, colloidal substances, and suspended matter that are abundant in the raw water20umThe above-mentioned substances can be controlled by manual valves or fully automatic controllers for a series of operations such as backwashing and forward washing. Ensure the water quality produced by the equipment and extend its service life.

　　Activated carbon filter

　　The system selects nut shell activated carbon filters, which can adsorb electrolyte ions and also perform ion exchange adsorption. Due to the adsorption effect, the concentration of adsorbed and imitated substances on the surface increases. Therefore, it also has a catalytic effect, removes pigments, odors, a large amount of biochemical organic matter in water, reduces the residual chlorine value and pollutants in water, and removes trihalides in water(THM)And other pollutants, the working cost is very low.

　　Ion exchange softening system Dosing system

　　Ion softening system/Dosing system

　　ROThe equipment is designed to dissolve solid substances for concentrated discharge and the use of fresh water, and to prevent the concentrated water end from being particularly importantROThe concentrated water side of the membrane module eventually appears in the equipmentCaCO3,MgCO3When the concentration product is greater than its equilibrium solubility constant, it crystallizes and separates, damaging the inherent characteristics of the membrane element. Before entering the reverse osmosis membrane module, an ion softening device should be used or an appropriate scale inhibitor should be added to prevent carbonate.SiO2Crystal separation of sulfate.

　　ROMembrane scale inhibitorThis compound formula is primarily applied to the scale prevention of membrane tubes in reverse osmosis membrane systems. It is rich in organic phosphates and dispersants, etc., and can effectively control the adhesion of crystallized scale and amorphous granular sludge on the surface of the membrane tubes at the same time. It has a good effect on water scale such as calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate and calcium fluoride, and can be widely used in brackish water, high-salt water, process water and other applications.

　　Flocculant(If the system has a dosing device:Preparation, injection and precautions of polymer flocculants: The primary effect of adding flocculants to water is to make colloids and organic matter in water flocculate together to form large and heavy flocculent deposits, thereby enhancing the filtration effect of the pre-filter. The dosage of flocculant should be adjusted accordingly according to the changes in the quality of the raw water.

　　The operation of the metering pump(If the system has a dosing device:(1) Read the operation manual of the metering pump. (2) Start the dosing pump in the order specified in the instruction manual. (3) If there is air at the suction inlet of the metering pump, it can be completely discharged through the exhaust valve.

　　Precision filter

　　Precision filters are selected to remove residual suspended solids, non-spherical particles and colloids and other substances in the influent water, so as toROThe subsequent equipment such as the system works more and more reliably. The filter element is5umThe purpose of melt-blown filter elements is to remove the excess that is missed by the upper-level filtration unit5umThe removal of impurities. Prevent it from entering the reverse osmosis equipment and damaging the surface of the membrane, thereby damaging the desalination function of the membrane.

　　Reverse osmosis system host

　　Reverse osmosis equipment is used to apply a satisfactory pressure to the solvent in the solution(It's usually water.)Through reverse osmosis membranes(Or it is called a semi-permeable membrane)When separated, it can adapt to various types of raw water with different salt contents, especially in water treatment projects with high salt content, it can achieve excellent technical and economic benefits. Reverse osmosis has a high desalination rate, high recovery rate, stable operation, small floor space, and simple operation. While removing salt, reverse osmosis equipment also removes most colloids and large-molecular-weight organic substances.

　　Selection of reverse osmosis equipment4A total of inches of reverse osmosis membrane elements8The root, the shell is4Each root is packed in a shell2Root membrane elements, equipped with high-pressure pumps, conductivity meters, concentrated water cleaning valves, high and low pressure protection switches, solenoid valves... Wait a moment. Their primary functions are as follows:

　　Reverse osmosis membrane

　　A reverse osmosis membrane is planned in the reverse osmosis pure water equipment. The pressures at both ends of the membrane are different. Driven by the pressures at both ends, the raw water is pressed through the reverse osmosis membrane. The salt with a lower concentration will permeate towards the salt with a higher concentration. The equilibrium state that can be reached is the osmotic pressure of the liquid. When the pressure on one side rich in brine is greater than the osmotic pressure on the other side, the flow in the opposite direction occurs, and the reverse osmosis process takes place. Reverse osmosis membranes are semi-permeable membranes artificially synthesized using special techniques to complete the reverse osmosis phenomenon of aqueous solutions. The pore size of reverse osmosis membranes is0.0001Micron(μm)Only water molecules can pass through, while solutes cannot pass through reverse osmosis membranes. In the clear water system of a pure water machine, reverse osmosis membranes specifically refer to formed reverse osmosis membrane filter cartridges. The reverse osmosis membrane filter element is the core component of the clear water system of a pure water machine. Only when a reverse osmosis membrane is used can it be called a pure water machine.ROMembranes can remove heavy metals, chemical substances, particulate matter, viruses, radioactive substances and other harmful substances to the human body from water.
