Landscape water treatment sewage water treatment

1. The 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 treated water can generally achieve a %% desalination rate. 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 microorganisms and 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 (cation and anion 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.
2. 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, sodium, etc. 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 types of water contain different salts, If you separate it with 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 in it will not penetrate. In this way, the water on both sides will gradually be separated. The salt concentration fuses until it is 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-mentioned 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 that in water with salt (such as raw water), Applying a pressure greater than the natural osmotic pressure causes osmosis to proceed in the opposite direction, forcing 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.
The working principle of the reverse osmosis purified water machine
It passes the raw water through a fine filter, a granular activated carbon filter, a compressed activated carbon filter, etc., and then pressurizes it through a pump, using a pore size of /mm (equivalent to the large intestine The reverse osmosis membrane (R membrane) of bacillus size/, virus/) turns higher concentration water into low concentration water, and at the same time isolates all impurities such as industrial pollutants, heavy metals, bacteria, viruses, etc. that are mixed into the water in large quantities. In this way, it can meet the physical and chemical indicators and hygienic standards required for drinking, and produce 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 methods currently mastered by humans. The highest in technology, the cleanliness reaches almost %, so people call this water production machine a reverse osmosis purified water machine.
