What are the functions of the raw water pump and high-pressure pump in reverse osmosis pure water equipment?

Released Date: Jul 14,2020 Article Source: Yuanlai Water Treatment
In reverse osmosis pure water equipment, there are two pumps: one is the raw water pump for tap water, and the other is the high-pressure pump for the RO system. So, what are the differences between these two pumps and what functions do they play respectively?

In the reverse osmosis pure water equipment, there are two pumps: one is the raw water pump for tap water, and the other isROThe high-pressure pumps of the system. So, what are the differences between these two pumps and what functions do they play respectively?

Raw water pump:

The raw water pump provides pressurization guarantee for the sand filter, carbon filter and fine filter of the reverse osmosis pure water equipment. The inlet water pressure is stable and sufficient, serving the purpose of pressurization. Ensure that the water pressure after pressurization is greater than the permeation resistance of the filter, carbon filter and fine filter, so that the pressurized water passes through the pretreatment systemROThe system provides an adequate water source.

High-pressure pump:

The high-pressure pump is for reverse osmosisROThe water quality separation of the membrane provides pressure difference driving force because of the reverse osmosis pure water equipmentROMicropores on the membrane surface0.5~10MmThe pre-treated purified water will not pass through without the pressurization of a high-pressure pumpROThe membrane is used to separate pure water from concentrated water.ROThe micro-pores on the membrane surface are tiny and the resistance is greater than that of pretreatment. Therefore, a high-pressure pump needs to be added to provide higher pressure for the pretreatment water to pass throughRO Membrane. It can be said that the high-pressure pump isROThe "heart" of the device, its superior performance will determineROWhether the system can operate normally, that is to say, the quality of the high-pressure pump is also extremely important for the pure water equipment. Without the high-pressure pump, the pre-treated water will not be able to pass throughROThe membrane cannot separate pure water from concentrated water either. From this, it can be seen that the high-pressure pump is also very important.

EDI ultra-pure water system

EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

Non-negative pressure water supply equipment

Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

Constant pressure water supply equipment

Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
