The two-stage reverse osmosis system is a highly efficient solution designed for industrial water treatment. This system employs advanced reverse osmosis technology to greatly enhance the water purification capacity through a two-stage process.

In the first stage, the raw water undergoes pretreatment to remove large particle impurities like suspended solids and sediments using specialized equipment. In the second stage, high-performance reverse osmosis membranes are used to selectively remove dissolved solids, heavy metals and microorganisms, ensuring that the effluent quality is optimal. This system is widely used in various fields such as electronics, pharmaceuticals, and food and beverage industries, as it effectively meets the demand for high-purity water.

Working Principle:

The system operates through several stages that enable the efficient removal of impurities and enhancement of water quality. The stages include:

• Pretreatment: Raw water passes through equipment designed to remove suspended solids and other large particle impurities, ensuring the subsequent reverse osmosis membrane is fully protected.
• First-stage reverse osmosis: The pretreated water goes through the first reverse osmosis unit, where water molecules pass through the reverse osmosis membrane, leaving behind dissolved solids and contaminants, resulting in the production of pure water.
• Second-stage reverse osmosis: The first-stage pure water then enters the second reverse osmosis unit for further refinement, removing residual contaminants and improving water quality.
• Water output and monitoring: The high-purity water produced is subjected to real-time testing utilizing a water quality monitor to ensure that it meets the predetermined water standards.

Product Functions:

The two-stage reverse osmosis system comes with a range of functions that include:

• Efficient impurity removal: The system is capable of removing over 95% of all dissolved solids, heavy metals, organic matter, and bacteria.
• Water quality improvement: The system produces high-quality pure water that meets international standards required by various industrial needs.
• Wastewater reuse: The system achieves industrial wastewater treatment and recycling, fostering the sustainable use of water resources.
• Real-time monitoring: The system comes equipped with a water quality monitoring instrument to gauge the water quality at any moment, ensuring water safety.

The maximum operating temperature for this equipment is 45℃ which should not be exceeded during operation to avoid potential damages.

The maximum operating pressure is 41bar which also should be taken into account to ensure the stable work of the equipment.

If the pressure drop exceeds 1bar, it may lead to a compromised performance.

Regarding the PH values, the recommended range for continuous operation is between 2 and 11.

For short-term cleaning, the PH value range can be expanded to 1~13.

For water flow rate, the maximum rate is 4040 3.6t/h or 8040 19t/h based on the specific model you are using.

For water supply SDI, it should be less than or equal to 5 to ensure the quality of the water produced by the equipment.

The allowable free chlorine content in the water should not exceed 0.1ppm to keep the equipment functioning effectively.
