How to operate the 5 micron security filter

1. Description:
The water treated by the pretreatment system passes through a 5-micron filter, which mainly removes the particles larger than 5 μm that pass through the multi-media filter and the activated carbon filter, and further protects the reverse osmosis system.

2. Precautions for use:
1) When the pressure drop at the inlet and outlet of the filter is greater than 0.1MPa, replace the filter element;
2) If it is used continuously for more than three months, replace the filter element.

How to Run a Reverse Osmosis Filtration
1. Description:
After being treated by a two-stage reverse osmosis system, 97% of dissolved solids, salts and ions can be removed from the water.

2. One stage reverse osmosis unit
2.1 The first-stage high-pressure pump is controlled by the following states:
2.1.1 Automatic
In the automatic state of the selection button of the field control cabinet, there are two starting methods:
a. Joint control of liquid level and time
① After the raw water pump is started for 5 seconds, the starting conditions of the high-pressure pump are satisfied.
② When the water level of the pure water tank (T-2) is below the high level, and after 12 o’clock in the evening, the high-pressure pump will start automatically. When the water level of the pure water tank reaches the high level, the original water pump will automatically stop.
2.1.2 Manual control
① When production water is needed during the day, press the start button on the central control cabinet to start the system, and when it needs to be stopped, press the stop button to stop the system.
② When the automatic system of the system fails, select the button on the field control cabinet to be in the manual state, and then press the manual start button to start the pump.
2.2 Notes:
1) Observe the flow meters of permeate and concentrated water, and adjust the RO concentrated water discharge valve to make the permeate volume reach more than 70%. Record the RO membrane inlet pressure, concentrated water pressure, and compare the pressure difference. If the pressure difference exceeds 4 kg under the same water supply conditions, please chemically clean the RO membrane.
2) Record the desalination rate of the RO membrane. If the desalination rate is lower than 97%, chemically clean the RO membrane.
3) Record the water production of RO. If the water production drops by 15% under the same conditions, the RO membrane needs to be chemically cleaned.
4) When the first stage RO pump is started, the pH probe of the permeate water will detect the pH value of the influent water and start the sodium hydroxide pump to keep the permeate water value between 8.2-9.2.

3. Secondary reverse osmosis unit
3.1 The first-stage high-pressure pump is controlled and operated by the following states:
3.1.1 Automatic
In the automatic state of the selection button of the field control cabinet, there are two starting methods:
Combined level and time control
① After 5 seconds after the primary high-pressure pump is started, the start-up conditions of the secondary high-pressure pump are met.
② When the water level of the pure water tank (T-2) is below the high level, and after 12 o’clock in the evening, the high-pressure pump will start automatically. When the water level of the pure water tank reaches the high level, the original water pump will automatically stop.
3.1.2 Manual control
When production water is needed during the day, press the start button on the central control cabinet to start the system, and when it needs to stop, press the stop button to stop the system.
When the secondary reverse osmosis high pressure pump is started, the pH probe before the pump will detect the pH value of the influent water. If it is lower than 6.0, the sodium hydroxide pump will start, and when it reaches 7.05, the sodium hydroxide pump will stop.
3.2 Notes:
1) Observe the flow meters of permeate water and concentrated water, and adjust the RO concentrated water discharge valve to make the permeate water reach more than 85%. Record the RO membrane inlet pressure, concentrated water pressure, and compare the pressure difference. If the pressure difference exceeds 4 kg under the same water supply conditions, chemical cleaning of the RO membrane is required.
2) Record the desalination rate of the RO membrane. If the desalination rate is lower than 97%, chemical cleaning of the RO membrane is required.
3) Record the water production of RO. If the water production drops by 15% under the same conditions, the RO membrane needs to be chemically cleaned.

4. Chemical cleaning of reverse osmosis (RO) systems
4.1 When one of the following situations occurs, chemical cleaning should be carried out
1) Under normal water supply conditions, when the pressure difference between the RO membrane inlet and outlet is greater than 4kg
2) Under normal water supply conditions, the water production decreases by 15%
3) The desalination rate is less than 97%
4.2 Preparation of cleaning solution
When the RO membrane is inorganic fouling and scaling, use acid cleaning
① Acid cleaning uses citric acid
② The cleaning water tank is 1000kg. After adding citric acid, it is made into an acidic cleaning solution with a pH greater than 2.
When the RO membrane is organically polluted, use alkali cleaning
① Alkaline cleaning uses sodium hydroxide
② Add sodium hydroxide to 1000kg of product water (1000kg of cleaning water tank) to prepare a cleaning solution with a pH greater than 8 and less than 12
4.3 Cleaning operation
1) Add a 5μm filter element to the cleaning filter
2) Prepare a suitable cleaning solution
3) The RO system is out of service. Close the RO water inlet valve, product water valve and liquid level valve, open the product water return valve and concentrated water return valve, and close the cleaning and discharge valve.
4) Close the outlet valve of the cleaning pump, open the cleaning circulation return valve, and start the cleaning pump.
5) Detect the pH value of the solution in the cleaning water tank.
6) When the pH of the cleaning water tank is stable and up to the standard, slowly open the outlet valve of the cleaning pump, inject the cleaning liquid into the RO system, and adjust the circulating return water valve so that the pressure of the RO membrane opening does not exceed 2.5kg
7) After the cleaning solution circulates in the RO membrane for 10 minutes, stop the operation of the cleaning pump, let the cleaning solution soak in the membrane for 30 minutes, and then turn on the cleaning pump to circulate. Repeat this. During the above operation, if the cleaning solution circulating back to the water tank is turbid and dirty, the cleaning solution should be drained, the cleaning solution should be reconstituted, and the chemical cleaning should be performed again. To no turbidity, dirt, foreign matter, particles.
8) After cleaning is completed, open the cleaning discharge valve. Drain cleaning fluid into waste line.
9) Fully open the RO inlet valve, open the raw water valve, and flush the RO membrane. Detect the pH of the effluent, and restore the valve to the normal operating state after it reaches the normal state. The system resumes normal operation.

How to run a 0.1 micron precision filter

1. Description:
The 0.1 micron precision filter is mainly used to remove particles larger than 0.1 μm in water to ensure the particle size requirements of the water point.

2. Notes:
1) When the pressure drop at the inlet and outlet of the filter is greater than 0.08MPa, replace the filter element;
2) If it is used continuously for more than six months, please replace the filter element.

1. Operation process:
1) Ventilation. Open the compressed air into the balloon valve to make the pressure close to 0.6Mpa/square centimeter, and then observe the current and voltage on the ozone machine.
2) The ozone generator is powered on. Turn on the low-voltage power supply (green button) of the ozone generator. At this time, the cooling fan of the machine should be observed to work, and after two minutes, an obvious smell of ozone should be smelled.
3) Open the pure water valve. Immediately after the ozone machine works, the pure water valve is opened to pour water into the oxidation tower. Pay attention to whether the valve positions of the oxidation tower are appropriate. Note that bubbles can be seen escaping upward from the oxidation tower microscope.
4) Shut down. When the water level reaches a certain height, close the pure water valve, cut off the power of the ozonator (red button), and turn off the oxygen valve (unscrew the pressure reducing valve screw counterclockwise).

2. Precautions for use
1) When the compressed air pressure is less than 2Mpa/square centimeter, do not continue to use it.
2) Water must be strictly prevented from flowing backwards from the oxidation tower to the ozonator.
3) When the cooling system fails, the yellow indicator light will be on and an alarm will sound.
4) The output pressure of ozone must not exceed 0.1Mpa.
The working current indicated by the ammeter should be very stable. If the working current indication changes greatly, the ozone generating unit may be damaged, so it should be shut down and repaired by professionals.
