5 Stage Reverse Osmosis System Water Filter - Deluxe with Bio-Activated Carbon and Foam Carbon Filter - 100GPD Membrane, 285L Drinking Water Daily, Ecological with NSF without BPA
A Reverse Osmosis (RO) system is a water treatment technology that uses a semi-permeable membrane to remove impurities and contaminants from water. It operates by applying pressure to the water, forcing it through the membrane while leaving behind dissolved solids, particles, and other contaminants.
Here's how an RO system typically works:
Pre-filtration: The water first goes through a pre-filter, usually a sediment filter, which removes larger particles like dirt, rust, and sediment.
Reverse Osmosis: The pre-filtered water is then pressurized and passed through a semipermeable membrane, which has extremely tiny pores. These pores allow water molecules to pass through while rejecting larger molecules and ions, effectively filtering out impurities such as dissolved salts, heavy metals, pesticides, bacteria, viruses, and some organic compounds. The filtered water is referred to as permeate or product water.
Concentrate Disposal: Alongside the permeate water, a portion of the water (usually around 20-30%) called the concentrate or reject water carries the rejected impurities and is directed to a drain or waste outlet. This helps to flush out the impurities and maintain the effectiveness of the membrane.
Post-Filtration: The permeate water may then pass through a post-filter, such as activated carbon, to further improve taste and remove any residual odors or remaining impurities.
The overall result is clean, purified water that is free from most contaminants. Reverse osmosis systems are capable of removing a wide range of impurities, including dissolved salts, heavy metals like lead and arsenic, chlorine, fluoride, bacteria, viruses, and many organic and inorganic compounds.
RO systems are commonly used in households, businesses, and industries where high-quality water is required for drinking, cooking, or manufacturing processes. They provide an effective means of improving the taste, odor, and overall quality of water by reducing the presence of various contaminants
