Industry Online Reverse Osmosis/ RO Device for Water Treatment, Water Purification (ROS-2210)

1. General
The ROS-2210 combines reverse osmosis control and dual conductivity measurement. It is equipped with a typical process control program for the RO system. It can easily and clearly view the measurement data of the inlet water conductivity and produced water conductivity and the operating status of the RO equipment. Combine PLC and two-way conductivity meter.
The latest full-view LCD screen and image flow control panel make it easier to reflect the status of pumps, valves and pressure detection. The menu parameter settings in the password mode can meet the various indicators of the system automatic operation.
The instrument has been further optimized with many improvements and version upgrades. It is very suitable for the automatic management of the first-stage reverse osmosis water-making equipment. It only needs to add a small amount of electrical components to achieve manual and automatic double compatibility. In a typical system, the complicated problems are simplified.

2. Process Flow Selections
There are two typical operation modes for RO system (as shown in Fig.1A: Source tank supply water; and B: Tap water supply ). This instrument can operate in both modes in A and B.


3. Main control funcion:
Low feed water protection function: 
In case of source water supply break-off (1. Water tank pressure, 2. Supply water pressure too low), the "Source water liquid level and Source water tank" lamp will be lightened, the LCD screen status display " NO ",  and the buzzer will give an alarm, the controller will shut down the whole RO system. 
After that, the controller will keep detecting the low feed switch. When the water supply is resumed, the system will delay one minute (the status display interface displays 1 minute to start the countdown) and then be restarted system. 
Low pressure protection function:
 If the security filter is dirty, or the pipeline leaks, the normal water supply pressure can not be provided to the RO system, indicating that the pressure is insufficient, a low-pressure alarm occurs, the 'low-voltage switch' lamp is lightened, and the LCD system status display "LO", the buzzer alarm, the controller shuts down the entire RO system.
After that, the system delays for 1 minute ( (the status display interface displays 1 minute to start the countdown) and then be restarted system. If after 3 times re-starts, they system can't return to the normal working status, the system enters the deadlock protection state, prompt the reason for downtime, and the buzzer alarms, waiting for manual processing.
 High pressure protection: 
If the RO membrane is dirty, the pipeline pressure will rise. After reaching the limit value, a high-pressure alarm will appear, the 'high-voltage switch' lamp is lightened, and the LCD system status display will display the "HI", buzzer alarm. The controller closes the entire RO system and opens the flush valve for pressure relief.
After that, the system continuously detects the high-voltage switch. If the pressure is restored, the flush valve is closed, and the delay is 1 minute ( (the status display interface displays 1 minute to start the countdown) and then be restarted system. If after 3 times re-starts, they system can't return to the normal working status, the system enters the deadlock protection state, prompt the reason for downtime, and the buzzer alarms, waiting for manual processing.
Conductivity over limit alarm: 
When the conductivity of the produced water is higher than the set upper limit value, the 'excessive' lamp is lightened, the controller opens the over-standard valve for discharge.
When the conductivity of the produced water is lower than the set value, the controller closes the over-standard valve, the produced water flows to the pure water tank.
Pure water level control function:
The pure water tank has two liquid levels, which are high liquid level and low liquid level, and can 
also be used in parallel as a single point. When the pure water tank liquid level is lower than the low liquid 
level and the high liquid level at the same time, the controller immediately starts the RO system to produce 
water, until the water storage tank liquid level is higher than the low liquid level and the high liquid level, 
the system is flushed with water -> water full standby.
Timing Membrane flushing function:
 The controller's running program is built-in: start-up flushing, water full flushing, continuous water production after N hours of flushing, continuous standby after N hours of flushing,  all flushing time can be set in the user menu, and flushed countdown time can be monitored in the 'System Run Status' interface.
