Under-sink reverse osmosis filtration systems provide clean, safe, and great-tasting drinking water from your kitchen tap. These systems use a series of stages to remove contaminants, impurities, and unwanted particles from your water supply. This article will delve into the various under-sink reverse osmosis filtration stages and how each stage contributes to providing clean, high-quality water.
The Pre-Filtration Stages
The pre-filtration stages remove larger particles and protect the more delicate reverse osmosis membrane that follows. These stages typically include the following:
● Sediment filter: This first stage removes larger particles such as sand, silt, and rust from the water, preventing them from clogging the subsequent filters and ensuring efficient filtration.
● Activated carbon filter: In the second stage, an activated carbon filter removes chlorine and other chemicals that could damage the reverse osmosis membrane. This stage also helps reduce unpleasant tastes and odors.
The Core Filtration Stage
The heart of the under-sink reverse osmosis system is the semi-permeable reverse osmosis (RO) membrane. This stage is responsible for removing the majority of contaminants, including:
● Dissolved solids: The RO membrane filters out dissolved solids such as salts, metals, and minerals, significantly reducing the total dissolved solids (TDS) content in the water.
● Bacteria and viruses: The RO membrane's pore size is so small that it can effectively filter out bacteria, viruses, and other microorganisms, ensuring your water is safe to drink.
● Chemical contaminants: The membrane also helps remove chemical contaminants, such as pesticides, herbicides, and industrial pollutants, which can harm human health.
The Post-Filtration Stages
After passing through the reverse osmosis membrane, the water goes through post-filtration stages to further improve its taste and quality:
● Carbon polishing filter: This stage uses another activated carbon filter to remove any remaining tastes and odors and ensure fresh and clean water.
● Remineralization filter: Some under-sink RO systems include a remineralization filter that adds beneficial minerals, such as calcium and magnesium, back into the water. This stage improves the taste of the water and balances its pH, making it less acidic.
● Ultraviolet (UV) sterilization: For additional safety, some systems are equipped with a UV sterilization stage that uses UV light to neutralize any remaining bacteria, viruses, or microorganisms that may have slipped past the RO membrane.
Storage Tank and Faucet
After the filtration stages, the purified water is stored in a storage tank until you need it. When you open the dedicated faucet for your under-sink reverse osmosis system, the water is dispensed directly from the storage tank, providing clean, refreshing drinking water on demand.
The Last Note
Understanding the different stages of under-sink reverse osmosis filtration helps you appreciate the complexity and effectiveness of these systems in providing clean, safe drinking water. Each stage is crucial in ensuring your water is free from contaminants, impurities, and unpleasant tastes or odors.
