How Customers Use Automatic Valves in RO System
In a 4000 LPH brackish water RO system, automatic valves play an important role in controlling water flow, protecting equipment components, and simplifying daily operation. Compared with manual valve systems, automatic valves help reduce operator workload and improve overall system coordination during continuous water production.
When the system starts operating, the automatic inlet valve opens according to the PLC control program, allowing raw water to enter the pretreatment section and RO unit in sequence. During shutdown or abnormal operating conditions, the valve can close automatically to prevent unnecessary water flow or pressure fluctuations inside the system.
Many customers use automatic flushing valves to clean membrane surfaces before and after system operation. During flushing mode, the valve changes the water flow path to discharge concentrated water and reduce scaling accumulation on membrane surfaces. This process helps maintain membrane performance and reduces manual flushing work for operators.
FAQ
Q1. Which water sources are compatible with this RO system?
This equipment can process various feed water sources including borewell water, city water supply, low-TDS brackish water, and other industrial water sources with moderate salinity levels.
Q2. What level of salt removal can be achieved?
Under standard operating conditions, the RO membrane system can effectively reduce dissolved minerals and salts with a rejection performance generally reaching 97–99%.
Q3. What consumable parts require periodic replacement?
Routine consumables such as PP sediment filters, activated carbon media, and softening materials should be replaced based on inlet water quality, operating hours, and maintenance schedules.
