If sediment has suddenly begun to appear in your well water, the problem may involve soil and/or sand that has found a way to penetrate the seal where your well enters the bedrock. Unfortunately, resealing such sand entry points can be quite involved. Fortunately, you can prevent sediment from impacting your water quality by installing a filter system on your well.
Of course, for the best results, you will need to choose from a range of filtration system options. If your well's water contains unwanted sediment, keep reading. This article takes a closer look at three different types of sediment filters, as well as the particular benefits of each one.
1. Centrifugal Separators
When it comes to removing sand, sediment, and other debris, few filtration systems perform as well as a centrifugal separator. In addition to being used to filter well water, centrifugal separators also play a key role in filtering the water used in farm irrigation systems.
Centrifugal separators do not rely on screens or other filter elements that require periodic replacement. Instead, water flows into the vertical separator, which creates a centrifugal motion that pushes sediment against the walls of the separator. Then the sediment-free water moves back up and out of the separator through the tube in the middle. The sediment, meanwhile, remains trapped at the bottom of the separator, where it must be manually flushed out from time to time.
Centrifugal separators excel at separating larger sediment particles - specifically, those with a size equivalent to a 200-mesh filter. Because centrifugal separators have a harder time isolating smaller particles, many people install them in conjunction with finer filtration media. Be sure to select a centrifugal separator sized to match the flow rate of your well.
2. Spin Down Filter
Spin down filters function in much the same way as centrifugal separators. Both filtration systems separate contaminants by funneling water downward and back up through a vertical tube equipped with a drainage port at the bottom. However, spin down filters differ in that they use filter screens to help remove debris from the water.
Such filter screens come in a wide variety of sizes, as measured in mesh number. Larger mesh numbers mean that the filter's fibers weave together more tightly, allowing it to trap smaller particles. Ideally, you should select the coarsest possible filter screen that successfully removes the sediment in your water.
3. Filter Cartridges
To maximize the material removed from your well water, many people choose to install filtration systems that utilize disposable filter cartridges. Such filters consist of a tightly woven membrane. Over time, the pores of the filter do clog up with debris, meaning you must be proactive about changing out filters that have reached the end of their lifespan.
Filter cartridges come in a wide range of sizes. Manufacturers express these different sizes in terms of the minimum particle diameter, as measured in microns. Dual-grade depth filters can trap particles as small as 5 micron.
Needless to say, such filters can remove virtually all foreign matter from your water. In most cases, however, you won't need a filter quite that dense - or that expensive. Most homes experiencing sediment issues can achieve the best results by selecting a pleated surface filter with a micron range between 30 and 50.
If your well has begun to draw up unwanted sediment along with its water, you should strongly consider investing in a filtration system.
