Sediment filters, as the name suggests, are used to remove excess sediment from water that passes through them. Sediment filters do not remove any chemicals or heavy metals dissolved in the water. They also do not affect the taste or smell of the water, so make sure you have a sediment problem before choosing to use one of these filters.
When deciding on what rating to go with, there are two factors to keep in mind for sediment filters: the micron number and whether the filter is nominal or absolute. The micron number shows the smallest sediment particle the filter can trap. 1-micron filters can catch the smallest of particles, while 20- or 50-micron filters only catch the largest sediment particles. Nominal filters catch about 85% of particles that are the size of their micron rating or larger, while absolute filters catch 99.9% of those particles. The rating you choose to use is up to personal preference; it all depends on what kind of particles are present in the water. Filters that are excessively tight can lower water pressure, so it’s best to experiment a little to see which type is right for you.
Pleated Sediment Filter Cartridges
Pleated filters, also called surface filters, are thin filters that catch sediment particles on their surface. These filters are made with a wide surface area that can hold a large number of sediment particles. Pleated filters are typically used until their outer surface is completely covered in particles and then disposed of, but some high-end pleated filters can be reused. These filters work best when dealing with uniform-size particles. If all the particles are roughly 5 microns in size, an absolute, 5-micron pleated filter will work effectively and last a long time due to its wide surface area. If the particles vary in size, smaller particles will slip through the filter and larger particles will quickly eat up surface area.
Surface Filters (Pleated Sediment Removal Filters) are made in a thin sheet so that only the surface captures sediment particles. These are known in the market place as “pleated filters” because of their accordion-shaped pleated structure.
The way the pleats are arranged gives the filter a lot more surface area than normal polypropylene filters.
One of their great advantages of a good pleated sediment removal filter is that they are washable and reusable, more often in larger than smaller micron sizes.
- Polypropylene filters have more dirt holding capacity, and they are usually more effective if a variety of particle sediment sizes are being filtered at the same time.
- Pleated filters have a much larger surface area and therefore it has more capacity for filtering particles of the same size.
It is also easier to manufacture pleated sediment removal filters to a specific micron size other than its counterpart the polypropylene filter.
As stated, they can also be cleaned and reused.
- Pleated Sediment removal filters can make up for the lack of depth by providing a much larger filter surface area.
WHICH IS THE BEST SEDIMENT REMOVAL FILTER TO USE?
The longest-lasting most effective sediment removal filters use pleated polypropylene or cellulose and polyester, while inexpensive sediment filters use a wound or spun mesh nylon.
Due to their larger surface area and low water resistance, Pleated Sediment Removal Filters result in a low water pressure drop while providing higher flow rates and much greater filtration capacity than spun or string wound filters.
Good Quality Pleated Sediment Removal Filters can often be cleaned and re-used.
