Add time: 2025-09-25
When people talk about a Johnson screen, they are usually referring to a wedge wire screen. This product was first developed by Johnson Company, which is why the name “Johnson screen” became widely used in the industry. Today, it is a common term for wedge wire screens in water treatment, mining, chemical, and food industries.
A Johnson screen is made by welding V-shaped wires onto supporting rods. This creates continuous slots that allow water or liquid to pass through while blocking solid particles. Thanks to this unique structure, the screen offers high strength, precise filtration, and long service life. Unlike traditional filter materials, a wedge wire screen does not clog easily, and it can be cleaned and reused many times.
In practical use, Johnson screens are found in water wells, wastewater treatment plants, and industrial filtration systems. For example, in groundwater projects, the screen acts as a well screen to prevent sand from entering the pump while ensuring stable water flow. In the food industry, it can be used for brewing, sugar processing, and other liquid-solid separation applications.
Another advantage of the Johnson screen is its flexibility. It can be manufactured in different diameters, lengths, and slot sizes to meet the needs of different projects. This makes it suitable for small-scale filtration as well as large industrial installations.
In short, the Johnson screen is not just a product name. It represents a reliable and efficient filtration solution. Whether you call it a Johnson screen or a wedge wire screen, its role in modern filtration and water treatment is irreplaceable.
