Reverse osmosis (RO) is a widely-used water purification technology that effectively reduces contaminants from water by using a semi-permeable membrane. This advanced filtration process is essential for producing high-quality drinking water and is utilized in various residential, commercial, and industrial applications. RO systems are designed to filter out a broad spectrum of contaminants, ensuring that the water you consume is clean, clear, and reduced from harmful substances.
The process of reverse osmosis is integral to addressing many water quality issues, such as removing dissolved salts, bacteria, viruses, and organic compounds. Given its efficiency and effectiveness, RO technology has become a cornerstone of modern water treatment solutions.
At Aquaporin, we enhance traditional reverse osmosis systems with our innovative Aquaporin Inside® technology. Our advanced technology, featured in our membranes and solutions, deliver high flow rates, exceptional contaminant rejection, and energy-efficient water treatment. These capabilities help address critical challenges in industrial and municipal water management, such as water scarcity, by tapping into previously unusable water sources, pollution, insufficient reuse, and high energy consumption, providing a more responsible and cost-effective solution for modern water treatment needs.

What is Reverse Osmosis?
Reverse osmosis (RO) is a highly effective water treatment method designed to reduce a wide range of impurities from water, resulting in exceptionally clean and pure water. This process involves forcing water through a semi-permeable membrane under pressure. The membrane is engineered to allow water molecules to pass through while blocking larger molecules and contaminants.
The semi-permeable membrane used in reverse osmosis is a critical component that acts as a fine filter. It effectively prevents unwanted molecules from passing through and reduces a variety of contaminants, including:
- Salts and minerals: These are dissolved in water and can contribute to hardness and scaling in pipes and appliances.
- Bacteria and viruses: Microorganisms that can cause diseases are effectively reduced, thereby also reducing potential health risks.
- Chemical pollutants: Includes industrial chemicals, PFAS, pesticides, and pharmaceuticals that may be present in the water supply.
The result of the reverse osmosis process is purified water with significantly reduced levels of contaminants. This makes RO an ideal solution for producing clean water. Reverse osmosis systems are widely used in various settings, including residential homes, commercial establishments, and industrial facilities.
Why is it called "Reverse Osmosis"?
The term "osmosis" refers to the natural movement of water molecules from an area of low solute concentration to an area of high solute concentration through a semi-permeable membrane. This process occurs to equalize the concentration on both sides of the membrane. "Reverse osmosis" reverses this natural process. By applying external pressure, water is forced from an area of high solute concentration to an area of low solute concentration, effectively separating the contaminants from the water.
How does Reverse Osmosis work?
A complete water treatment system based on reverse osmosis involves several key steps:
- Pre-treatment: Before the water reaches the RO membrane, it goes through a pre-treatment stage. This typically includes processes that avoid or minimize RO membrane performance loss, degradation, and damage. The necessary and adequate pre-treatment steps are highly dependent on the feed water source, feed water composition, and application.
- Reverse osmosis: The pre-treated water is then forced through the semi-permeable RO membrane under pressure. This membrane has tiny pores that allow water molecules to pass through while blocking contaminants such as dissolved salts, organic compounds, and microorganisms.
- Post-treatment: After passing through the RO membrane, the water may go through additional post-treatment to polish the water and reduce any remaining taste or odor, ensuring the highest quality, and in larger installations and some purifiers, it is re-mineralized to achieve chemically stable water suitable for distribution and drinking.
Addressing modern water management challenges with Reverse Osmosis
Industrial and municipal water management face pressing problems such as water scarcity, pollution, insufficient reuse, and high energy consumption. These challenges necessitate more efficient and responsible water treatment methods. Global surges in prices have further urged industries and municipalities to seek energy-efficient solutions.
Aquaporin’s advanced RO technology addresses these needs by providing:
- High flow rates: Ensuring rapid and efficient water tratment.
- Exceptional contaminant rejection: Effectively reducing a wide range of impurities, including salts, heavy metals, bacteria, and viruses.
- Energy efficiency: Reducing the energy required for industrial water treatment, which lowers operational costs and environmental impact.
Our Aquaporin Inside® technology offers a more responsible and cost-effective solution for modern water treatment, helping to meet the critical demands of industrial and municipal water management.
