What is Double-stage reverse osmosis

1, The two-stage reverse osmosis is that the first-stage reverse osmosis permeate water is adjusted to the PH value, and then the second-stage high-pressure pump is sent to the second-stage reverse osmosis system to obtain the process of permeating water.
2, The system desalination rate of the first-order reverse osmosis is ≥99.5%. In this way, the raw water with a salt content of less than 1000 ppm can be directly treated with water without ion exchange to achieve the third-grade water standard of laboratory water “GB6682-2008”.
Two-stage reverse osmosis main configuration:
3, Pretreatment system: raw water pump, multi-media filter, activated carbon filter, automatic water softener, pipeline, valve
DRO reverse osmosis system: 1st high pressure pump, 2nd high pressure pump, reverse osmosis membrane, reverse osmosis membrane shell, membrane frame, control system water inlet, solenoid valve, flushing solenoid valve, pressure regulating valve, high pressure switch, low pressure switch, precision Filters, pipes, valves.
4, Storage system: level controller, water tank.

Double-stage reverse osmosis Process

Original water tank → original water pump → quartz sand filter → activated carbon filter → softener → dosing device → security filter → booster pump → first-stage reverse osmosis module → PH regulator → intermediate water tank → water quality inspection point → secondary high pressure Pump → two-stage reverse osmosis module → ultraviolet sterilizer → pure water tank → water point.

The two-stage reverse osmosis equipment process system is introduced in detail:

1, Raw water tank: store raw water to ensure that the raw water quality is within the controllable range and the raw water storage ensures normal production.

2, Raw water pump: pumping raw water to provide a continuous stream of raw water for subsequent processes.

3, Quartz sand filter: primary filter device to filter out large particles of impurities in raw water.

4, Activated carbon filter: Primary filtration device that absorbs excess residual chlorine in the water and other substances that can be adsorbed by activated carbon.

5, Softener: exchanges calcium and magnesium ions with raw water to remove hard materials from the water, ensuring softening of water and no scale in subsequent process module equipment.

6, Dosing device: The dosing device is mainly responsible for adding scale inhibitors and other water treatment agents. The scale inhibitor has the same effect as the softener, and also prevents the scale of the equipment pipe and the inside.

7, Security filter: This is the last primary filtration device before reverse osmosis filtration. It is similar to the ultrafiltration filtration system in order to provide a safer filtration protection for reverse osmosis and remove various substances that may damage the RO membrane in raw water. .

8, Booster pump: Pressurize raw water to ensure reverse osmosis can have normal use pressure.

9, First-stage reverse osmosis module: the first stage reverse osmosis treatment system.

10, Intermediate water tank: stores water after being treated by the primary reverse osmosis module.

11, Secondary booster pump: secondary reverse osmosis treatment.

12, Ultraviolet sterilizing device: The final sterilizing treatment of raw water.

13, Pure water tank: pure water produced by the last equipment.

14, Transfer pump: delivers pure water for water points.

15, Water point: Where to use reverse osmosis water.
