Cartridge filter

A cartridge filter is a piece of tubular filtration equipment that can be used in various products for an array of filtration requirements. A cartridge is encased within a housing or a casing and used to remove unwanted particles, pollutants, and chemicals from liquids. The cartridge is exposed to water, liquid or solvent that needs filtration, as it flows inside the housing and passes through the filter element. It can also remove submicron particulates.

You can find two categories of cartridge filters


Surface filters and


Depth filters

Surface filters

Surface filters prevent solids and contaminants from passing through the medium. Outside of the filter medium, they are restricted. The passage of fluid through a layer of material that limits particles on the surface is referred to as surface filtration. The size of particles prevented from entering the medium by the cartridge filter is larger than the medium's typical pore size. The surface filter becomes caked with particles on the exterior over time, restricting the flow beyond an acceptable level. The filter surface must be cleaned and reused at this stage. Surface filters are less expensive and have a shorter shelf life than other types of filters. The filter media has a lower mechanical strength (with the exception of filter medium made of stainless steel).

Depth filters

Within the medium, depth filters capture all impurities, pollutants, and solids. Depth filtration is defined as a thicker layer of media (or many layers) that creates a difficult path for particles to go through and prevents them from passing through. The size of the particles is significantly smaller than the medium's typical pore size. Contaminants pass through the depth filter and become trapped; when the pores in the filter become closed, they must be cleaned with a reverse flow of fluid or replaced with a fresh medium. A depth filter is more costly than a surface filter, but it has a longer shelf life. The filter media has a high mechanical strength.

How to Clean Filter Cartridges?

To clean a cartridge filter effectively, remove any big dirt and debris particles before soaking it in a filter cartridge cleaning solution to remove built-up oils and scum. Remove the bigger debris using a garden hose, scrubbing between the pleats from top to bottom. The longer your filter cartridge lasts, the more thoroughly you clean it. It's not a good idea to wash it down and put it back in the tank right away. Give your cartridges the complete treatment each time you clean them.

When to Replace a Filter Cartridge

Most people replace their filter cartridges every 3-5 years, but don't base your decision only on the amount of time that has gone; instead, assess your filter's effectiveness. Depending on the strain placed on the cartridge, your time period may be longer or shorter.

There are three ways to tell when your filter cartridge is no longer effective.

Cleaning Frequency: When the pressure gauge climbs 8 PSI over normal operating pressure, it's time to clean the filter cartridges. It should be replaced if the period between these increases in pressure begins to reduce considerably. Keep track of the filter pressure and the date your cartridge filter was cleaned. It has reached its "half-life," and it's time to replace it when the time between cleanings is half of what it used to be.

Water Quality: Another sign that your cartridge filter is expiring is if the pool water remains hazy or green despite correct chemical balance, or if you have to run your filter longer or use more sanitizer to get clean and clear pool water. Clean the cartridge initially, but if the problem persists after a few days, the cartridge is likely no longer capable of filtering the water as well as it once did. This is because the fibers split a little more each time a cartridge is cleaned, enabling fine debris and algae to flow through unfiltered. After 12-15 cleanings, Uncial recommends replacing the filter cartridge.

Filter Damage: The third technique to tell if a cartridge filter needs to be replaced is to properly check it every time you clean it, searching for rips or tears in the fabric. Damage to the filter will limit the filter's ability to filter effectively. If there are tears or rips in the cloth, or if the rubber end cap of the cartridge is cracked, it must be replaced.

Another method for calculating the time between pool cartridge replacements is to use the filter size vs. pool size tipping point.

Pool filter cartridge

A pool filter cartridge is a piece of tubular filtration equipment that can be used in various products for an array of filtration requirements. A cartridge is encased within a housing or a casing and used to remove unwanted particles, pollutants, and chemicals from liquids. The cartridge is exposed to water, liquid or solvent that needs filtration, as it flows inside the housing and passes through the filter element. It can also remove submicron particulates.

You can find two categories of pool filter cartridge                


Surface filters


Depth filters

Surface filters

Surface filtration, as the names suggest, is concerned with the retention of particles mostly on the surface. The particles that are kept form a layer of material known as a "cake layer," which serves to improve filtering effectiveness even further. If the filtration rate is originally about 50-60%, it will increase to 100% once the layer of cake is made. Solids and pollutants are prevented from passing through the medium by surface filters. They are limited outside of the filter media. Surface filtration is the flow of fluid through a layer of material that restricts particulates on the surface. The size of the particles that the pool filter cartridge prevents from entering the medium is greater than the medium's normal pore size. Over time, the surface filter becomes caked with particles on the outside, limiting the flow beyond what is tolerable. At this point, the filter surface must be cleaned and reused. Surface filters are less costly than other types of filters and have a shorter shelf life.

Depth filters

Depth filters are a type of filter that uses a porous filtering media to keep particles in the middle of the medium rather than simply on the surface. When the fluid to be filtered includes a high load of particles, these filters are often employed because, in comparison to other types of pool filter cartridge, they can hold a significant quantity of particles before getting clogged. To remove solid pollutants from the liquid phase, depth filtration is utilized, which is constituted by several porous layers with depth. The particles are trapped throughout the medium's structure, rather than on the surface, due to the tortuous and channel-like character of the filtering medium. Depth filters provide the extra benefit of being able to capture a large number of particles without sacrificing separation performance. The sand filter is a frequent feature of depth filters, and they may be employed with far greater filtration rates than other designs. These features have helped to strengthen the usage and popularity of depth filters as a separation tool. Depth filter designs are always evolving and improving to meet the demands of industry, thanks to continual improvements in process technology.



It's really quite feasible that dirt and particles are avoiding your filter cartridge. Look for tears in the pleats or cracks on the ends of your cartridge. Misplaced or misaligned components within the filter are another source of dirt getting around (rather than through) the cartridge. The position and arrangement of internal manifolds may be found in the owner's handbook for your filter. Look for fractures or missing O-rings in these internal components. Before putting the top back on, it's sometimes a matter of correctly "seating" the cartridge into the base of the filter tank.

Mineral deposits can block the small holes of a pool filter cartridge in hard water regions. As the water attempts to force through the blocked cartridge, your pressure gauge will most likely register greater than before. To address this problem, immerse your filter cartridge in a 10:1 water-to-acidic solution to dissolve the minerals.

Oily substances, such as suntan oil, cosmetics, hair care products, and simply plain old body oils, can clog cartridges. The oils in your cartridges may be broken down by soaking them in a TSP solution. If your pool has an oil problem, apply a pool enzyme like Pool Perfect to break down the oils. It's incredible!

Sand filter

Sand filters are used in the water purification process as a phase in the treatment process. There are three main types.


Rapid (gravity) sand filters


Upward flow sand filters


Slow sand filters

All three techniques are widely utilized in the water industry around the world. The first two require the use of flocculants chemicals to operate successfully, but slow sand filter may create extremely high quality water without the use of chemical aids, reducing pathogens from 90% to >99% (depending on the strains), taste, and odor. Sand filters, in addition to being utilized in water treatment facilities, may also be used in single family homes since they use materials that are readily available to the majority of people.

Rapid sand filters

The rapid sand filter, also known as the rapid gravity filter, is a type of water filter that is often used in municipal drinking water facilities as part of a multi-stage treatment system. Rapid sand filters were initially created in the 1890s, and by the 1920s, better versions had been produced. George W. Fuller planned and built the first modern fast sand filtration facility at Little Falls, New Jersey.  By the 1920s, rapid sand filter were commonly employed in major municipal water systems because they required less area than slow sand filters.

Upward flow sand filters

The Upward Flow Water Filter is a small, easy-to-build water filter for eliminating suspended dirt or organic matter that can discolor or contaminate potable water. The filter is especially beneficial in rural regions, where surface water of questionable quality is frequently utilized. Clean water may make a significant difference in a family's health.

The filter is simple to build and use, and it will supply enough clean water for a family or a party of around ten people. It can run for up to a year before it has to be cleaned, depending on the quality of the water source.

Slow sand filters

In water purification, slow sand filter are used to treat raw water and create a usable product. They're usually 1 to 2 meters deep, have a rectangular or cylindrical cross shape, and are mostly used to treat surface water. The flow rate needed by the filters, which generally have a loading rate of 200 to 400 liters per hour per square meter, determines the length and breadth of the tanks (or 0.2 to 0.4 cubic meters per square meter per hour).

Slow sand filter perform differently than other drinking water filters in that they rely on a complex biological layer that forms naturally on the sand's surface. Unlike its equivalents for Ultraviolet and pressure treatments, the sand does not filter anything and merely serves as a substrate. Although they are frequently the favored technique in many developing countries due to their cheap energy needs and reliable performance, they are also used to treat water in certain wealthy countries, such as the United Kingdom, where they are used to treat London's water supply. Slow sand filters are presently being explored for disease control in hydroponic nutrient solutions.


  • It is inexpensive
  • It filters medium to large debris
  • It will typically last for seven years


  • Needs regular maintenance
  • More pressure is required when sand has an overwhelming amount of debris.
