Filters do not last forever. In the course of doing its job, a filter becomes progressively more resistant to the flow of liquid. As this happens, flow is reduced and, as we’ve mentioned before, this process may even be accelerated by the fact that the partially blocked filter retains smaller and smaller particles. The price of …
If a filter is doing its job, its life will be limited. Eventually it will have filtered out and collected enough particles to be severely restricted or totally block liquid flow. When this happens, the filter or filtration media must be replaced. A clogged filter will, at minimum, have process consequences as particle accumulations build up …
The useful life of most media filters is determined by the size and quantity of particles they capture. Each filter has only a limited number of sites to trap particles. Once a site traps a particle, flow through that site’s passage is either reduced or stops completely. When a sufficient number of sites are blocked, flow through …
One important step on the path to solving any problem is understanding the enemy and the risk it poses. The enemy, in this case particles, come in a wide variety of sizes and shapes. A particle’s effect on the ultimate use of the part it contaminates may depend not only on its size, but on …
Many topics can’t be covered in a single, one page blog entry. For this reason, some of the more involved topics will be discussed in several sequential blogs with a common theme. This is the start of one such series about filters and filtration. In parts cleaning, filtration is applied to liquids used to clean …
