Industrial reverse osmosis water purification equipment is a critical equipment commonly used in manufacturing and other industrial fields.
Through reverse osmosis technology, it is able to remove impurities, solutes and microorganisms from contaminated raw water to obtain high-purity pure water.
The following will introduce the process flow of industrial reverse osmosis pure water equipment.
1.Raw Water Purification Treatment:
The first step of industrial reverse osmosis pure water equipment is to purify the raw water.
Raw water can be a natural water source, such as river water, lake water, or groundwater or tap water.
In order to pre-treat it before reverse osmosis membranes to remove suspended solids, colloidal substances, color, taste, and large particulate matter, methods such as filtration, sedimentation, and activated carbon adsorption are often employed.
2.High Pressure Pump Pressurization:
The purified raw water needs to be pressurized by a high-pressure pump to meet the requirements for access to the reverse osmosis membrane.
High-pressure pumps are capable of increasing the raw water pressure to the operating pressure required for reverse osmosis membranes, typically between 10-20 megapascal (MPa).
3.Solute separation:
The raw water pressurized by the high-pressure pump enters the reverse osmosis membrane module and begins solute separation.
In reverse osmosis membranes, raw water is filtered through a semi-permeable membrane, and the solutes are trapped on the membrane surface to form concentrated water.
Through this separation, harmful substances such as dissolved substances, microorganisms, and heavy metal ions can be removed from the water to obtain high-purity pure water.
4.Brine Discharge & Concentrated Water**:
In the reverse osmosis process, in addition to the water purification output, a portion of the brine is generated.
This part of the concentrated water contains a membrane-trapped solute and a small amount of water that needs to be discharged.
At the same time, in order to improve the utilization rate of water, the concentrated water can also be used for other industrial processes or re-enter the reverse osmosis equipment for treatment.
5.Water Purification Stabilization:
Although most of the solutes have been removed from the pure water treated by reverse osmosis membrane, it may still come into contact with the environment and absorb some impurities during storage and use, resulting in changes in water quality.
In order to ensure the stability of the purified water, it can be treated by adding an appropriate amount of stabilizers, disinfectants or re-filtration to ensure the purity and health safety of the water quality.
6.Water Quality Monitoring:
In order to ensure the proper operation and purification quality of industrial reverse osmosis pure water equipment, water quality monitoring is required.
Monitoring tools and methods include pH testing, dissolved oxygen measurements, microbial testing, and quantitative detection of specific contaminants.
Through water quality monitoring, possible problems can be found and solved in time to ensure the stability of pure water quality.
To sum up, the process flow of industrial reverse osmosis pure water equipment includes raw water purification treatment, high-pressure pump pressurization, solute separation, concentrated water discharge and concentrated water**, water purification stabilization, and water quality monitoring.
The continuous action of these steps allows the raw water to be efficiently treated to obtain high-purity pure water, which provides an important water resource guarantee for industrial production.
