A Johnson strainer nozzle, also known as a wedge wire screen nozzle, is a key component in filtration systems. It is designed to provide efficient and reliable filtration, ensuring that only clean and pure fluids pass through while trapping contaminants.
Our Johnson strainer nozzles are widely installed on mixed beds to achieve ion exchange processes.
Mixed Bed Filtration
The mixed bed uses a fixed bed exchange process, including an upper water inlet device, a middle drainage device, a lower porous plate, a water retaining plate, a filter cloth layer, a valve system, and a compressed air inlet device.
Mixed bed filtration is used primarily in water treatment, deionization, and purification systems. It involves a mixture of cation and anion exchange resins packed together in a single vessel. This combination allows for the effective removal of both positively and negatively charged ions from the water, resulting in highly purified water.
The mixed bed device is mainly used for softening, desalination, and pure water production of industrial water in boilers, power plants, textiles, printing and dyeing, chemicals, electronics, pharmaceuticals, etc.
Functions of Johnson Strainer Nozzle in Mixed Bed
▪ Efficient Filtration
The wedge wire design provides a large open area, allowing for high flow rates while maintaining precise filtration. This ensures the ion exchange resins remain in place, preventing them from being washed away during backwashing or normal operation.
▪ Uniform Distribution
These nozzles ensure the even distribution of water throughout the resin bed. This uniform flow distribution is essential for maximizing the contact time between the water and the resins, leading to more effective ion exchange and higher water purity.
Advantages of Johnson Strainer Nozzle in Mixed Bed
▪ Stainless steel material, corrosion resistance, durability, and long service life.
▪ V-shaped wire structure is not easy to clog and easy to clean.
▪ High efficiency and durability, low maintenance, reduce frequent replacement and downtime, save costs.
▪ Customizable to meet various application requirements.
We can provide various Johson strainer nozzles for mixed beds. Slot size, material, and type can be customized.
