With the increasing demand for high-flow filtration, many customers prefer to adopt high-flow filter cartridges for their filtration system. The reason they use high-flow filter cartridges is to improve filtration efficiency. But, can we do better? Can we improve the efficiency of the high-flow filter cartridge? The answer is absolute yes.
We will introduce knowledge about high-flow filter cartridges, help you to select, use, extend service life and improve the efficiency of large flow filter cartridges. If you are interested in those aspects, you can not miss out on this article.
We summarize some main series of high-flow filter cartridges and popular brands in the market, which are shown below.
Are you familiar with them? Or have you already used them in your plant? What’s your user experience with them? You can share with us.
If you want to reduce the cost of large flow filter cartridges, the key point is to explore the balance between efficiency and service life. However, the interception efficiency is directly proportional to the filtration accuracy, while the accuracy is closely related to the resistance and flow rate.
That means, with high accuracy, the efficiency will also be good, but the life of filter cartridges will be shorter; on the contrary, if low precision and long service life are provided, filter cartridges’ efficiency will be reduced.
Here are two cases that show what exactly we said.
From the photo, it is shown that the filter element was entirely clogged in the valley. However, the impurities were unevenly distributed in peaks and other places. According to reliable calculations, 1/7 area is yellow, and 6/7 area is white. That means, only 1/7 parts of the filter element are effectively used, due to the unreasonable design of the filter cartridge.
A large number of rigid particles blocked the filter element, which contained sediments and a small amount of colloid. There is only one-layer membrane in this filter cartridge, which leads to easy clogging and a lack of filtration area. When particles are pretty much, especially the colloid, the membrane is easily blocked and loses filtration ability.
We can summarize from those two cases that enough filtration area offers not only a large dirt-holding capacity but also long service life. However, when the inappropriate design is utilized, the usage rate of the filtration area would be low, which also results in low efficiency and high cost.
Before we try to improve efficiency for high flow filter cartridge, there are some problems we should notice.
Problem 1: leakage problem of ultrafiltration often happens in the pre-filtration stage, which leads to a bad filtration effect.
Problem 2: the filtration layer is small and lacks space to contain more dirt, this is a common issue for filter cartridges.
Solutions for those problems
To extend the service life of high flow filter cartridges, we need to first figure out the reason for short life of large flow filter cartridges.
If you forget to replace the filter cartridge, the particles will increase significantly when passing through the RO membrane, which will cause serious damage to the RO system.
It raises the costs of the whole filtration system and affects the filtration performance. We would like to introduce another blog, that explains the factors connected to the service life of filter cartridges in detail.
A qualified high-flow filter cartridge should have the ability to handle a high flow rate and have a large filtration surface for a large dirt-holding capacity. Based on the different operating conditions, a suitable type of high-flow filter cartridge should be applied.
For example, if the operating condition requires high pressure and high temperature, a high flow filter cartridge like Max-Iron which is equipped with a metal protection mesh is needed. When you need a large filtration surface, a multi-layer pleated filter cartridge like Max-A can be a great choice.
Why do we always focus on researching how to improve the efficiency of large flow filter cartridges? Because we deeply know, that is the key to helping end users reduce filtration costs.
When a large flow filter cartridge is completely used with proper design, the efficiency of it would be definitely high. That helps to decrease the frequency of changing the filter cartridge and finally reduces the cost.
