A raw water pretreatment system
is very important as the basis for pure water production
. Therefore, if you want to produce pure water, you must choose a place with better raw water quality. Such as mountain springs, deep wells, etc. A very important index involved here is conductivity. Generally speaking, the conductivity is lower. The purer the water. The water treatment processes currently used are reverse osmosis systems. The desalination rate that the treated water can generally achieve. Let me introduce the components of this system.
Raw water pump
The raw water pump is used to provide raw water pressure for the raw water pretreatment system. If the raw water has pressure, you don't need this equipment at all. Generally required raw water pressure
Raw water tank
The function of the raw water tank is simpler and is used to store raw water. This is because they are afraid that if the raw water supply is not available, they will be transferred.
Quartz Sand Filter
This equipment is mainly used to filter microbial dust in the water to make the raw water clear.
Activated carbon filter
This equipment is mainly used to filter residual chlorine in water.
Dosing system anion and cation exchange system
In the past, this system was an anion and cation exchange system, but it was very difficult to operate and was labor- and material-consuming. Now the dosing system is changed to add antiscalant directly to it.
Second reverse osmosis system
The reverse osmosis system
is the core component of the entire pure water system
Only through reverse osmosis can the standard of pure water be achieved. Reverse osmosis system mainly uses membrane filtration process. Water molecules can then pass through the reverse osmosis membrane. Other ions such as calcium, magnesium and sodium are discharged with the wastewater. The following are the components of this system.
Precision filter
This filter mainly filters large particles in the water.
Special high-pressure pump
Generally, the high-pressure pump we use here is the Southern Special Pump. Provide strong power for reverse osmosis equipment.
Reverse osmosis membrane
Reverse osmosis membrane
uses membrane filtration technology. The purpose of purifying water is to allow water molecules to pass through other ions that cannot pass through.
The principle of reverse osmosis

First of all, we must understand the concept of osmosis. Osmosis is a physical phenomenon. When two kinds of materials containing different salts If water is separated by a semi-permeable membrane, you will find that the water on the side with less salt content will penetrate through the membrane into the water with high salt content, but the salt contained will not penetrate. In this way, the water on the side with less salt content will gradually penetrate. The salt concentration on both sides blends until they are equal. However, it takes a long time to complete this process. This process is also called osmotic pressure. But if you try to add a pressure on the water side with high salt content, the result can also be The above osmosis stops, and the pressure at this time is called osmotic pressure. If the pressure is increased again, it can penetrate in the opposite direction, and the salt will remain. Therefore, the principle of reverse osmosis desalination is to apply salt-containing water, such as raw water, to water that is more natural than natural water. The greater osmotic pressure causes osmosis to proceed in the opposite direction, pushing the water molecules in the raw water to the other side of the membrane and turning it into clean water, thus achieving the purpose of removing impurities and salts in the water

< br/>The working principle of reverse osmosis purified water machine

It is to pass the raw water through fine filter, granular activated carbon filter, compressed activated carbon filter, etc., and then pressurize it through a pump, using a pore diameter of / equivalent The reverse osmosis membrane R membrane, which is the size of E. coli / virus /, turns higher concentration water into low concentration water. At the same time, it isolates all impurities mixed into the water in large quantities, such as industrial pollutants, heavy metals, bacteria and viruses, so as to meet drinking regulations. It has physical and chemical indicators and hygienic standards, and produces extremely clear and pure water, which is the best choice for the human body to replenish high-quality water in a timely manner. Because the purity of water produced by R reverse osmosis technology is the highest among all water production technologies currently mastered by mankind, The cleanliness is almost reached, so people call this water production machine a reverse osmosis pure water machine
