What is a sediment filter?
A sediment filter captures and removes particulate matter from your water, such as dirt and debris.
Sediment is a catch-all term for all non-liquid particulate matter in your water. Rust flakes can enter your water supply through corroded galvanized plumbing. Rainwater can transport silt, clay, soil, and sand grains into your well's groundwater supply. Changes in the flow of your water main can also transport sediment to your home.
The sediment filter serves as the first line of defense against dirt and debris. It keeps all of this solid particulate from entering your water supply and interfering with the performance of your water filtration systems.
What is the use of sediment filters?
Sediment filters are used in a wide range of applications:
1: Sediment pre-filters are used in restaurants and coffee shops to ensure the quality of their food and beverages.
2: Sediment filtration is used in whole-house filtration systems to prevent particulate matter from entering your faucets and showers and to extend the life of other filters.
3: Your pool filter cartridges are a type of sediment filter that prevents dirt and clay from contaminating your clean swimming water. Anywhere there is a need for clean water, you will most likely find a sediment filter.
How does a sediment filter function?
Mechanical filtration is the process by which sediment filters work.
Mechanical filtration prevents unwanted particulate matter from entering your water supply. Consider it similar to a screen door on your home. You want a cool breeze to blow through your house, but you don't want bugs or leaves to blow in with it. The screen door serves as a mechanical filter.
Similarly, sediment filters have enough porosity to allow water to flow into your home while capturing the dirt and sand carried by the water. Sediment filters are like a net that collects particulate matter in your water.
To catch large amounts of debris, some sediment filters have large surface areas. To filter out suspended particles, other sediment filters employ a depth gradient. These force water through thick walls of filter media that become increasingly tight as the water gets closer to the core, filtering out smaller and smaller particulates along the way.
What does a sediment filter get rid of?
Sediment filters remove visible particulate matter as well as any dirt, sand, dust, or debris that can be caught by their micron-rated capacity. Turbidity is also removed from water by sediment filters. Turbidity is the cloudiness caused by a high concentration of suspended solids in water. Water turns yellow, orange, or brown as a result of this.
Chemicals, heavy metals, bacteria, and dissolved particulate matter are not removed by sediment filters. They have no effect on the taste or odor of water. They are primarily used for defensive and preservative filtration. Sediment filters perform best when used as prefilters for other filtration systems. As a result, sediment filtration is frequently used in conjunction with other filtration methods such as reverse osmosis or ultraviolet purification.
Why are Sediment Filters important?
Sediment filters are typically used as the first stage of water purification. Its primary function, as the first line of defense, is to remove physical impurities or particulate matter from water. It keeps all solid particles out of your filtered water and improves the filtration efficiency of RO membranes and UV filters.
It is not in charge of altering the taste or odor of water. It is a preventative filtration method that does not remove chemicals, heavy metals, bacteria, viruses, or dissolved solids from water. Further stages of RO and UV purification remove these impurities.
