Types of Johnson filters
Strong industrial equipment like the Johnson filter makes it possible to purify water and other fluids for many uses. A few industrial sites use these models to filter big amounts of liquids, such as around 30,000 square feet. They also let smaller model sizes be used at home. These are ideal because families use more water daily than the amounts that can be stored.
- Strainer filters: These devices, also known as duplex strainers, catch large debris, dirt, and blockages in water pipelines. They work like baskets, purposely letting water flow out while trapping impurities inside them. What makes them different from other filters is that they do not need to be backwashed. Instead, they require manual cleaning, which can be done while the strainer remains in-line. This means that the water supply will not be interrupted during the cleaning process.
- Sand filters: They use the rule that sand easily traps dirt and impurities while allowing clean water to flow through it. A gravity-driven process where water flows downwards through different sand layers lets even the smallest particles be caught up. Then, filtered water is collected at the bottom part of the filter. The design results in water being nebulized out at over 4 gallons per minute per sq. ft. of effective filter area. This high rate of water filtration makes sand Johnson filters very popular for use in industrial sites. This is around four times more than what normal filters can do.
- Activated carbon filters: They reduce the number of organic chemicals and chlorine in the water. Doing this helps to greatly improve the water's color and taste. As the carbon inside the filter gets used up, it releases the impurities it held up. This requires the carbon to be backwashed so it can work properly again. Some models of this filter use a combined method of carbon absorption and oxidation using ozone.
- Fine filters: Also called micro filters or ultra filters, they are used to separate crude oil from its natural sources or treat drinking water. As their names suggest, they can catch specific microscopic impurities, like bacteria, while letting clean water through. The working method of fine filters is like that of sand filters. However, they make use of membrane technology. In this case, water is filtered under pressure forces it through a semi-permeable membrane that traps harmful microorganisms.
- NKPT filters: NKPT stands for non-knitted polytene tube. NPT filters put an end to the problem of biofouling, which happens when small living organisms and microbes sit down and grow on filter membranes. This reduces the filter's lifespan. The construction of NPT filters makes them very easy to clean and gives them a long lifespan. Cleaning is made possible through a process called backwashing, where water is forced back through the filter in the opposite direction. This process removes the dirt and impurities stuck in the filter.
Specifications & maintenance of johnson filters
Specifications
The specifications may differ depending on the type and application of a Johnson filter.
- Lengths: Typically, a Johnson filter length ranges from 0.5 to 20 inches. This is the length from the bottom of the filter to the top.
- Diameters:The diameter is the width of the Johnson filter. Its diameter typically ranges from 0.5 to 6 inches. The diameter affects the flow rate and filtering capacity of a filter.
- Mesh sizes: The mesh sizes refer to the number of openings in a specific area. Typically, Johnson screens have mesh sizes from 20 to 400. Fine mesh screens, for example, have more screens and fewer openings. It will collect more particles. The coarse mesh has fewer screens and more openings. It allows larger particles to pass through.
- Materials:Typically, Johnson screens are made of stainless steel, brass, or plastic. Stainless steel is strong and can withstand heat and chemicals. Brass is naturally antimicrobial. It can resist dirt buildup. Some Johnson screens, such as those used in seawater filtration, may be made of plastic. It is to resist corrosion and damage from chemicals.
- Slot sizes:The slot sizes of Johnson screens refer to the narrower gaps between the screen rods. Usually, the slot size of a Johnson filter ranges from 0.1 to 1 mm. A smaller slot size allows the screen to capture more debris and particles.
- Ends:Different types of end fittings are available for Johnson filters, such as flange connections, slip ends, and threaded ends. They allow easy installation and connection.
Maintenance
For the Johnson screen to filter properly, regular maintenance is necessary. Here are some applicable maintenance tips.
- Clean the filter element frequently. One can use a soft brush or cloth to wipe the surface of the Johnson filter, thereby removing dirt and impurities like debris, scales, or contaminants. This will prevent clogging and allow continuous fluid flow.
- Check the filter for signs of damage or wear. look for cracks, deformations, or blockages. If there's any damage, please repair it or replace the element immediately.
- Apply a proper amount of lubricating oil to the screen connection or sealing part to ensure a good connection. This will also facilitate installation and removal.
- Pay attention to the working temperature and pressure of the Johnson filter. Using the filter beyond its temperature or pressure limits can cause damage to its structure. The durability of the filter can be compromised.
- Monitor and adjust the flow rates of the Johnson filter. Users can control the filter's working conditions by adjusting the flow rates. This will avoid the strain and damage resulting from excessive filtration.
