What's RODI Water ?
RODI water, also known as reverse osmosis deionized water, is a highly purified form of water produced through a two-stage process. First, tap water undergoes reverse osmosis, removing most impurities and contaminants. Then, it's further purified through deionization, which removes remaining ions and dissolved solids, resulting in water with a near-zero total dissolved solids (TDS). Here's a more detailed explanation:1. Reverse Osmosis (RO):
- This stage uses a semi-permeable membrane to filter out large molecules, salts, and dissolved solids from tap water.
- RO typically removes 90-99% of contaminants, including metals, minerals, and other dissolved substances.
- The result is water with a lower TDS level but still contains some remaining ions.2. Deionization (DI):
- DI further purifies the water by removing the remaining ions and dissolved solids, bringing the TDS level down to near zero.
- This is achieved by exchanging the remaining ions with hydrogen and hydroxyl ions, creating ultra-pure water.
- DI is often used after RO to produce water suitable for applications requiring high purity, such as scientific research, pharmaceutical processes, and certain aquariums.
In essence, RODI water is a highly refined form of water, ideal for applications where the purest possible water is needed. For example, in the context of saltwater aquariums, RODI water is crucial for maintaining a healthy environment for reef tank inhabitants. It helps prevent algae blooms, heavy metal contamination, and other issues that can negatively impact coral and other sensitive marine life.
