In today's increasingly health-conscious society, more and more people are beginning to pay attention to drinking water health and water usage. This is because water quality usually contains a lot of impurities and scale, which can cause harm to the body and easily lead to problems such as kidney stones. The water purified by the pure water equipment is very suitable for drinking. It can balance the water electrolytes in the body, accelerate metabolism, and at the same time ensure the water supply for industries and daily life such as beverages and hospitals. 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. Working Principle:

　　ROReverse osmosis equipment adopts contemporary, energy-saving and effective membrane separation technology. The principle of reverse osmosis equipment is that under the action of pressure higher than the osmotic pressure of the solution, other substances cannot pass through the semi-permeable membrane, thus separating other substances from water. The pore size of reverse osmosis membranes is extremely small, so reverse osmosis equipment can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. from water.

　　Pure water equipment, simply put, is the equipment used to produce pure water. Pure water is widely used by us in: daily drinking, chemical industry, breeding, planting, beverages, etc. The following will briefly introduce to you the components of the equipment and the process of producing pure water.

　　①Pretreatment of reverse osmosis equipment

　　It is composed of a multi-media filter, an activated carbon filter and an automatic water softener.

　　1Multi-media filterIt is composed of fully automatic control valves, fiberglass reinforced plastic tanks and quartz sand of different grade ratios. It can effectively remove suspended solids and some colloidal substances in the raw water and reduce the turbidity of the raw water. And it can automatically perform backwashing.

　　2Activated carbon filterIt is composed of fully automatic control valves, good glass tanks and activated carbon of different water purification grades. It can effectively adsorb harmful substances such as heavy metals, free chlorine and chloroform in the raw water. And it can automatically perform backwashing.

　　3Water softenerIt is composed of fully automatic control valves, Kaineng Huayu fiberglass reinforced plastic tanks and grade Piolite resin. Calcium and magnesium ions in water can be effectively removed through a water softener. To prevent the reverse osmosis equipment from affecting the service life of the reverse osmosis membrane due to scaling during operation. And it can regenerate automatically.

　　Reverse osmosis water treatment equipment, applying membrane separation technology, can effectively remove charged ions, inorganic substances, colloidal particles, and organic matter from water. It is an excellent device in the processes of high-purity water preparation, brackish water desalination, and wastewater treatment. Reverse osmosis equipment can produce pure water and high-purity water to meet the needs of users in different industries and with different demands. It is widely used in fields such as electronics, medicine, light textile, chemical engineering, and power generation.

　　②The main unit part of the reverse osmosis equipment

　　The main unit of the reverse osmosis water purification equipment mainly consists of a security filter, a high-pressure pump, reverse osmosis membranes, and various control and display instruments.

　　1Security filterThe security filter is the last line of protection before the raw water enters the membrane. It can effectively remove the leakage from the pretreatment process５μm The substance. The main purpose is to prevent suspended particles from entering the reverse osmosis membrane elements and depositing on the membrane surface to contaminate the membrane elements.

　　2, High-pressure pumpProvide the pressure required for reverse osmosis to ensure the separation of solvents and solutes. The high-pressure pump is one of the key components of reverse osmosis equipment.

　　3, Reverse osmosis membrane groupThe reverse osmosis membrane group is composed of polymer fibers with a highly ordered matrix structure. Its aperture is１－１０A, that is, one billionth to one billionth of a meter (equivalent to one six-thousandth of the size of Escherichia coli and one three-thousandth of a virus), can effectively remove impurities such as dissolved salts, colloids, organic matter, heavy metals, trihalomethane intermediates produced by chlorination, and microorganisms from solvents by taking advantage of the separation characteristics of reverse osmosis membranes.

　　4Reverse osmosis membrane housingIt is used to accommodate reverse osmosis membrane elements, withstand pressure and create a high-pressure environment for reverse osmosis operations.

　　5FlowmeterThe pure water flowmeter and the concentrated water flowmeter measure separatelyＲＯInstant flow of pure water and concentrated water.

　　6Pressure gaugeMeasure the water pressure at all points of the reverse osmosis equipment.

　　7Concentrated water regulating valveFor regulationＲＯThe operating pressure of the equipment, the ratio of pure water to concentrated water, and the output of pure water.

　　8Conductivity meterMonitor the conductivity of the reverse osmosis effluent.

　　9Low-voltage switch"PreventＲＯThe high-pressure pump is idling or operating at a pressure exceeding the ultimate low pressure.

　　10Liquid level controllerThe reverse osmosis equipment is automatically shut down or started based on the liquid levels of the raw water tank and the pure water tank.

　　11Electronic control systemIt includes instruments and control equipment such as conductivity meters, which are used to control reverse osmosis equipment.
