What is reverse osmosis in water treatment

Reverse osmosis (RO) is a water purification process that effectively filter out dissolved solids, chemicals, bacteria, and viruses, ensuring clean and safe drinking water. It is a good water treatment solution for Lekki (both right wing and left wing sides of Lekki Epe Expressway in Lagos) and any other parts of Lagos with water problem.


There are different reverse osmosis system for different water problems like salt water, iron water, PH imbalance, odor, color, or other forms of impurities. Don't make the mistake of assuming all reverse osmosis system will be adequate for your water problems - it can cost you more!

How much does it cost to install a reverse osmosis system? It varies depending majorly on raw water quality and water usage (consumption rate).


Lets Examine common questions often asked about reverse osmosis system.

Q1: How often should I replace the reverse osmosis membrane in my system?

A1: The reverse osmosis membrane typically requires replacement every 2 to 3 years, depending on factors such as water quality and usage.

Q2: What signs indicate that my reverse osmosis system needs maintenance?

A2: Signs of a Reverse Osmosis (RO) system needing maintenance include decreased water production, slow flow rate, unusual taste or odor, and increased levels of impurities in the filtered water.

Q3: How often should I clean the Reverse Osmosis (RO) system's pre-filters?

A3: Pre-filters should generally be replaced every 6 to 12 months, but you may need to clean or replace them more frequently if your water source is heavily contaminated.

Q4: Is it necessary to sanitize the reverse osmosis system periodically?

A4: Yes, it is recommended to sanitize the Reverse Osmosis (RO) system every 6 to 12 months to prevent the growth of bacteria or mold and maintain optimal performance.

Q5: Can I perform Reverse Osmosis (RO) system maintenance myself, or should I hire a professional?

A5: We will recommend you hire a professional - RP Facilities Ltd. Repairs or system troubleshooting may require the assistance of a professional technician.

Q6: How can I improve the flow rate of my reverse osmosis system?

A6: If the flow rate is slow, you can try checking and replacing clogged pre-filters, checking the pressure in the storage tank, and ensuring proper water pressure to the system.

Q7: What is the ideal operating pressure for a reverse osmosis system?

A7: Most Reverse Osmosis (RO) systems operate optimally at a pressure range of 40-80 psi (pounds per square inch). Always install a pressure gauge to check the pressure and adjust if necessary.

Q8: How should I store my reverse osmosis system if I'm not using it for an extended period?

A8: If you plan to store the Reverse Osmosis (RO) system, it is crucial to drain and sanitize it, remove filters, and protect it from extreme temperatures to prevent damage.

Q9: Is it necessary to test the water quality after maintaining the Reverse Osmosis (RO) system?

A9: It is recommended to test the water quality after maintenance to ensure that the system is functioning correctly and providing the desired level of purification. A simple PH test and physical test may be enough depending on your internal QA/QC requirement.

Q10: Are there any specific maintenance tips for well water-based reverse osmosis systems?

A10: Well water-based Reverse Osmosis (RO) systems may require more frequent maintenance due to higher levels of sediment and contaminants. Regular testing, filter replacement, and system cleaning are crucial for their proper functioning. For best results, install water fiber filters or stainless steel cylinder filters with appropriate filtration media.
