>Industrial first-level reverse osmosis equipment
>That is, single-stage reverse osmosis equipment, using self-administered tap water as the source water , the conductivity of the primary reverse osmosis effluent is usually less than u/m or above, and can reach u/m or even lower during initial operation. The reverse osmosis device mainly separates the ion range in the solution. It does not require heating, and there is no phase change process, so it consumes less energy than traditional methods. The reverse osmosis device is small in size, simple to operate, and has a wide range of applications. Using a reverse osmosis device to treat industrial water does not consume a large amount of acid and alkali, and there is no secondary pollution. Its operating costs are also relatively low, and the water production volume can be customized according to different users.
>2. Principle of industrial first-level reverse osmosis equipment
>Reverse osmosis technology (R) is a membrane separation and filtration technology that utilizes the osmosis principle of the reverse osmosis membrane and is powered by pressure difference. It is the most advanced technology today. The most advanced and most effective membrane separation technology, it has been widely used in the purification and concentration of various liquids. Reverse osmosis membranes usually use polyamide composite membranes with a filtration pore size of only . micron. They can effectively remove impurities such as dissolved salts, organic matter, colloids, and microorganisms in water, and have extremely high salt removal rates and high resistance to chemical pollution. Equipment composed of reverse osmosis membrane elements is reverse osmosis equipment. Reverse osmosis equipment can be divided into single-stage reverse osmosis, primary reverse osmosis, secondary reverse osmosis, and double-stage R reverse osmosis. The system has the characteristics of good water quality, low energy consumption, no pollution, simple process and easy operation.

>, Quartz sand filter:
Quartz sand filter is made of
>Quartz sand< br/> >The filter material removes suspended solids from raw water and is a common rapid filtration equipment. When the water flow containing suspended solid particles passes through the filter material layer, the gaps in the filter material screen the suspended solids, making it easy for the suspended solids to be adsorbed on the surface of the filter material. When a certain amount of dirt is trapped on the surface of the filter material to form a filter membrane, the pressure difference between the front and rear of the filter will quickly increase over time until it fails. At this time, it is necessary to use reverse flow of water to backwash the filter material to suspend and loosen the quartz sand in the filter, so that the retentate adhering to the surface of the quartz sand and anthracite can be peeled off and taken away by the water flow to restore the filtration function. Design flow rate m/h, backwash intensity ~. The water discharged through quartz sand filter U＜. The wear of quartz sand becomes smaller after long-term use, and the quartz sand should be replaced once a year. The backwash drainage is connected to the water storage tank.
Activated carbon filter:
The work of the activated carbon filter is completed through the carbon bed. The activated carbon particles that make up the carbon bed have a lot of micropores and a huge specific surface area, and have strong physical adsorption capacity. Water passes through the carbon bed, and organic pollutants in the water are effectively adsorbed by activated carbon. In addition
>Activated carbon
>There are some oxygen-containing tube energy groups on the non-crystalline part of the surface, so that organic pollutants in the water passing through the carbon bed are effectively adsorbed by the activated carbon. Use activated carbon to remove low-molecular organic matter, free chlorine, odor substances, and heavy metal ions in water. Design flow rate m/h, backwash intensity. Replace the activated carbon filter material every year or so.
, Precision filter:
The function of the precision filter is to intercept particles larger than mu from the previous system to prevent large particles from entering the reverse osmosis membrane. After being accelerated by the high-pressure pump, such particles may penetrate the primary reverse osmosis membrane module, causing a large amount of salt leakage and scratching the impeller of the high-pressure pump. The filter element in the filter is replaceable and should be replaced when the pressure difference between the filter inlet and outlet is greater than the set value (usually.~).

>Fully automatic water softener
>:
The fully automatic softener is automatically controlled by an American (or Atuzu) program control valve, and the regeneration cycle is ~ hours. The control valve uses time mode to start regeneration, and the measurement is accurate. The work station consists of six steps: operation, backwash, regeneration, slow wash, fast wash, and salt tank water filling. The conversion of the work position is automatically recorded by the time controller in the automatic control valve. When the treated water volume reaches the preset value of the program, the controller sends a command signal to the drive motor, and the motor rotates to drive the multi-function valve core to rotate, changing the flow direction of the inlet and outlet water, thereby realizing automatic control. The regenerated salt liquid is sucked in by the negative pressure of the water ejector, and there is no need to set up a salt pump. For daily maintenance, you only need to add salt to the salt box.
>The function of the softener
> is to remove + and M+ from the water to prevent them from depositing on the concentrated water side of the membrane, forming scale, blocking the concentrated water membrane channel, and affecting the water production and production of reverse osmosis. Water quality.
, Reverse osmosis:
Reverse osmosis is currently the membrane separation technology with the highest filtration accuracy. Its filtering accuracy reaches .um. All substances in the tap water are filtered, without minerals and trace elements. This water can be drank directly. The pure water and the solution containing the solute are separated by a semi-permeable membrane that can only pass through the water. At this time, the pure water is The water on the water side spontaneously passes through the semipermeable membrane and enters the solution side, and the water surface on the solution side rises. This phenomenon is osmosis. When the liquid level rises to a certain height, the pressure on both sides of the membrane reaches equilibrium, and the liquid level on the solution side no longer rises. At this time, there is a pressure difference on both sides of the membrane, called osmotic pressure. If a pressure greater than the osmotic pressure is added to the solution side, the water molecules in the solution will be squeezed to the pure water side. This process is just the opposite of osmosis, which we call reverse osmosis. We can see from the process of reverse osmosis that due to the effect of pressure, water molecules in the solution enter pure water, the amount of pure water increases, and the solution itself is concentrated. The reverse osmosis membrane used in this equipment is a semi-permeable spiral wound membrane. When the raw water is sent to the reverse osmosis membrane under a certain pressure, the water passes through the tiny pores on the membrane and is collected to obtain pure water. The impurities in the water are For example, soluble solids, organic matter, colloidal substances and bacteria are intercepted by the reverse osmosis membrane, concentrated and removed in the interception liquid. It mainly consists of pretreatment and R host.
