RO Treatment Plants Malaysia

Reverse osmosis systems work by passing raw water through a semi-permeable membrane to get rid of various impurities. The technology has become increasingly popular for water purification in Malaysia due to the many benefits it provides for industrial and commercial applications.

Reverse Osmosis treatment plants can effectively remove dissolved solids, heavy metals, pesticides, herbicides, sediments, particles, nitrates, and sulfates. The filtration systems ensure clean, safe, and great-tasting water for various applications. 

Reverse Osmosis requires no chemical and membrane components are cost-effective to replace. RO treatment plants are typically automated systems; thus, you only need to schedule daily checks by on-site technicians or engineers.  

Factors that influence the performance of RO treatment plants

Let’s explore the profound factors that influence the performance of RO treatment plants, regardless of brand or model.


The condition of the RO system, including signs of scaling, damage, and fouling, can affect its performance. Regular inspection and proper cleaning of the membrane are essential to maintain optimal performance.



Water temperature directly affects RO system performance. Higher water temperatures increase RO permeate flow, while lower temperatures reduce it. Adjustments in pressure may be needed to compensate for changes in water viscosity due to temperature variations.

RO Pump Pressure

The RO membrane's design is matched with a specific pump pressure to ensure proper water flow and contaminant rejection. Operating below or above the recommended pump pressure can impact water flow and system efficiency.

Operating Parameters

Parameters such as feed water pressure, flow rate, temperature, and recovery rate need to be carefully controlled and optimized to achieve maximum efficiency and productivity while maintaining membrane integrity.

Salt Passage

This metric measures the percentage of salt that passes through the RO system. Lower salt passage rates indicate better performance in removing contaminants from water.


Different RO treatment plants have different capacities, in terms of the amount of water recovered as permeate or product water. Monitoring recovery rates helps assess system efficiency and water conservation efforts.

Tips for maintenance of RO treatment plants

Maintaining a Reverse Osmosis (RO) plant is crucial for ensuring optimal performance and extending its lifespan. First, you need to familiarize yourself with the user manual provided with your RO treatment system. The manual contains valuable information on membrane cleaning, re-installation procedures, dos and don'ts, and other maintenance guidelines specific to your system.

Subsequently, you can develop a maintenance schedule based on the recommendations in the user manual. Replace filters and membranes according to this schedule to ensure consistent water quality. 

Different components of the RO treatment plants require varying replacement intervals. At Delcol, we provide detailed information for the servicing and maintenance of filters, RO membranes, electrical components and other components of our RO treatment plants. You must adhere to the provided timelines to ensure optimal filtration performance.

Regularly clean and sanitize the RO system to prevent microbial contamination and maintain water quality. Cleaning should include pipes, filters, and the storage tank. Many professionals incorporate cleaning as part of the filter or membrane replacement service.

It’s also critical to conduct daily visual inspections to check for leaks or drips in the RO system. Promptly address any leaks by contacting a trained professional to avoid potential damage to the filtration system and minimize water wastage.

Also, don’t forget to clean the exteriors of the RO system regularly to prevent water contamination and maintain its appearance. A clean exterior not only enhances hygiene but also contributes to the overall longevity of the system.

Delcol offers state-of-the-art RO treatment plants that are tailored for different industries including the Food and beverage industry, Power and energy, Pharmaceutical, food and beverage, and chemical processing, among others. Contact us for more information regarding our products and services.
