Operation and Maintenance of RO Water Treatment Plant
Operation and Maintenance of RO Water Treatment Plant – Complete Guide | RO Store Chennai
Proper operation and maintenance of RO water treatment plants is essential to ensure high-quality purified water, increased membrane life, reduced downtime, and efficient system performance. At RO Store Chennai, we specialize in providing premium-quality RO components, spares, chemicals, filters, and RO plant O&M guidelines for domestic, commercial, and industrial systems across South India.
Whether you manage a 250 LPH RO plant, 500 LPH RO system, 1000 LPH RO plant, or large industrial RO water treatment plant, following a strict RO plant operation and maintenance procedure is crucial for long-term performance.
Key Steps in RO Water Treatment Plant Operation
1. Pre-treatment System Check
Before running the RO plant, it is essential to inspect:
Pressure Sand Filter (PSF)
Activated Carbon Filter (ACF)
Softener or Antiscalant Dosing System
Cartridge Filters (20-inch Jumbo Filters)
Proper pre-treatment reduces load on the RO membranes and prevents fouling and scaling.
2. Monitoring Feed Water Quality
Operators must regularly check:
TDS levels
Hardness
pH
Iron and silica levels
Chlorine levels (remove chlorine using activated carbon or dechlorination chemicals)
Monitoring helps ensure stable RO plant performance.
3. Checking Pressure Gauges & Rotameters
Accurate readings are essential for correct flow and pressure control:
Feed pressure
Permeate flow
Reject flow
Raw water pressure
Faulty gauges or rotameters can affect RO operation and water output.
4. Membrane Operation & Protection
RO membranes must be operated under:
Correct pressure
Correct recovery ratio
No chlorine exposure
Controlled scaling and fouling
Using RO antiscalant, membrane cleaners, and low-pressure switches helps protect the membranes.
Essential Maintenance of RO Water Treatment Plants
1. Cartridge Filter Replacement
Replace 5 micron / 10 micron filters every:
15–30 days (industrial)
1–3 months (domestic)
Dirty filters reduce pressure and affect membrane life.
2. Chemical Cleaning of RO Membranes (CIP)
Clean membranes when:
Permeate flow reduces
Pressure increases
Salt rejection decreases
Use:
Alkaline membrane cleaners
Acid membrane cleaners
Bio-fouling cleaners
Regular CIP restores membrane performance.
3. Antiscalant Dosing
Using high-quality RO antiscalant chemicals prevents:
Scaling
Mineral deposition
Hardness buildup
Silica fouling
This greatly increases membrane lifespan.
4. Pump & Motor Maintenance
Routine checks include:
Bearing lubrication
Vibration and noise monitoring
Motor winding inspection
High-pressure pump servicing
Keep raw water pumps and high-pressure pumps in top condition.
5. System Sanitization
Regular sanitization prevents:
Bacterial growth
Biofilm
Contaminated permeate
Use RO sanitizers, chlorine dosing, and flushing cycles.
6. Checking Electrical & RO Panel Controls
Inspect:
RO control panel
Relays
Timers
Starters
LP/HP switches
Automation systems
A well-maintained panel ensures seamless RO plant operation.
