Pre-treatment system
As the basis for the production of pure water is very important. So to produce pure water must be to choose the place where the quality of raw water is better. Such as mountain springs, deep wells and so on. Here involves a very important index is "conductivity", generally speaking, the lower the conductivity, the purer the water. Water treatment process are used in the reverse osmosis system, after treatment of water can generally reach 90% - 99% desalination rate; here I introduce the components of this system.
1, raw water pump
Raw water pump is the raw water pretreatment system to provide the role of the pressure of raw water. If the raw water pressure can be completely without this equipment. General requirements for raw water pressure >=0.3MPa
2, raw water tank
Raw water tank role is more simple, is the storage of raw water. This is afraid of raw water in case of supply for a transit (usually add a float switch is the whole system is more automated).
3, quartz sand filter
The use of quartz sand filter media in order to remove large particles of suspended solids in the raw water, sediment, impurities, etc., to reduce turbidity of the water. And also can make the water organic substances, bacteria, viruses, etc. with the reduction of turbidity and be a large number of removal, and for the post-filtration disinfection to create a good condition.
4, activated carbon filter
The use of activated carbon adsorption capacity to effectively adsorb organic matter in the raw water, free residual chlorine, colloids, particles, microorganisms, some metal ions and decolorization.
5, softening system (dosing system)
The use of ionic resins exchange performance, to remove calcium and magnesium ions in the raw water to prevent the impact of the subsequent equipment scaling, but the operation of the labor, materials. Changed to the dosing system directly to add scale inhibitors.
Mainly solve the following problems:
1, to prevent organic pollution;
2, to prevent colloidal substances and suspended solids clogging;
3, to prevent oxidizing substances;
<
4, to prevent reverse osmosis membrane surface scaling CaCO3, CaSO4, SrSO4, CaF2, SiO2, iron, aluminum oxides, etc. deposited on the membrane surface
Reverse osmosis system
Reverse osmosis technology in the successful application of pure water equipment, drinking water in China provides a good space for development. Reverse osmosis technology to achieve the completion of the need for a number of systems technology to cooperate with the realization.
1. treated water
The treated water can be sewage, tap water, river water, groundwater and other water sources. We usually use tap water and groundwater as the treated water for reverse osmosis treatment, the water quality is relatively more emotional, the degree of pollution is low, the processing efficiency is fast.
2. Pre-treatment system
Pre-treatment system for the treated water to make a simple water quality filtration. The treated water is as close as possible to the reverse osmosis technology on the water quality requirements. In the treated water, if the pretreatment is not carried out, then in the reverse osmosis treatment, due to certain magazines or high forcible corrosion is easy to reverse osmosis membrane damage and plug mouth.
3. High-pressure water pump
The whole reverse osmosis water treatment process, need a certain pressure. High-pressure water pump through the entire water treatment system to provide pressure, to ensure that who in the membrane through the hole when the speed and water supply requirements. High-pressure pumps must be used special stainless steel corrosion-resistant pumps, because the water treatment solution contains acid and alkali substances will be corrosive phenomenon, if the corrosion resistance is weak, corrosion, will cause the water so contaminated.
5. Intelligent control system
The new reverse osmosis equipment will be equipped with a special PLC intelligent control system. Through the intelligent system to detect the temperature gauge, pressure gauge and other instrument panel data changes. Controlled by computer with analog screen. Can control the normal operation of the whole set of reverse osmosis equipment. And according to the needs of water treatment for manual setting of water reference, according to the operating conditions of the equipment to issue an alarm prompt.
6. Sealed tank water
After the completion of the reverse osmosis equipment for water treatment, through the professional water tank for the treatment of completed water collection. The water tank should be clean and anticorrosive to avoid contamination of the water.
Auxiliary systems
Some other auxiliary systems such as, ozone sterilization system, light inspection, filling system. Also available ultraviolet light to sterilize, ultraviolet light will not have a residue, there are many foreign countries like to use ultraviolet light
