Reverse osmosis is a purification process designed to remove impurities from untreated water, known as feed water. It involves applying pressure to guide water through a semipermeable membrane, directing it from a side with a higher concentration of contaminants to a lower concentration, resulting in clean drinking water, often called permeate. The concentrated residual water, known as waste or brine, remains on the other side. This process relies on a semipermeable membrane with pores that selectively block contaminants while allowing water molecules to pass through.

In nature, osmosis causes water to concentrate as it moves through a membrane, seeking equilibrium on both sides. Reverse osmosis leverages the membrane's ability to block contaminants from entering the less concentrated side. By exerting pressure, it effectively extracts impurities from saltwater, ensuring that only pure water flows through. This groundbreaking method provides a reliable supply of purified water for various applications, offering trust in impeccably pure water suitable for different uses.

The Inner Workings of an RO System

The RO membrane, comprising more than one filtration element, is at the core of a reverse osmosis system. Every reverse osmosis water system includes the renowned RO membrane, a sediment filter, and a carbon filter, also known as pre-filters and post-filters. These filters play important roles in the overall filtration process.

Sediment Filter:

 In the initial phase, reverse osmosis systems use sediment filters to reduce particles like dust, dirt, and rust, ensuring water remains free from impurities before proceeding to subsequent purification stages.

Carbon Filter:

 Another vital component, the carbon filter, improves water taste and odor. It eliminates unwanted chemicals and organic compounds like chlorine, pesticides, and various Volatile Organic Compounds (VOCs). This comprehensive purification process, along with the RO membrane and multi-filter approach, delivers an advanced solution for enhancing water purity.

Semipermeable Membrane:

 Reverse osmosis systems extensively employ semipermeable membranes, skillfully applying pressure to encourage water to traverse the membrane, separating it from the solute. These synthetic membranes are indispensable for efficient purification at high pressure and can remove 98% of total dissolved solids (TDS), ensuring exceptionally pure and healthy water.

Initiating Your Water Filtration Journey

The reverse osmosis process starts with pre-filtration, where water encounters carbon and sediment filters. These filters work diligently to remove sediment and chlorine, preserving the integrity of the RO membrane. As water advances, it faces the reverse osmosis membrane, capable of extracting even the tiniest dissolved particles that are imperceptible.

After thorough filtration, water is stored in a tank, ready for consumption. The reverse osmosis system continuously purifies water until the storage tank reaches capacity, automatically stopping its operation. When you turn on your faucet for a drink, purified water will flow from the storage tank, meeting your hydration needs. Before reaching your glass, it undergoes a final refinement via another post-filter, establishing the highest water quality.
