In refinery and petrochemical operations, reactor internals have a direct impact on efficiency and safety. Among them, the hub lateral system plays a central role by distributing or collecting fluids evenly across the catalyst bed. A well-designed hub lateral prevents channeling, pressure imbalances, and catalyst loss, while extending reactor cycle life. What is a Hub Lateral ? A hub lateral consists of a central hub connected to multiple laterals radiating outward. Each lateral is fitted with precision slots or wedge wire screens that allow liquid or gas to pass while retaining catalyst or media. They are typically placed at the top or bottom of reactors for uniform distribution or collection. Compared to perforated pipes, wedge wire hub laterals offer precise slot sizes, higher strength, and resistance to fouling—making them ideal for hydrocracking, reforming, and desulfurization units. Key Design Considerations • Material selection: stainless steel, duplex, or nickel alloys dep...

 A wedge wire slot nozzle strainer is a stainless steel filtration component featuring V-shaped (wedge) wires welded to support rods, forming finely tuned slots that allow water to pass while retaining ion exchange resin or media. Made commonly from SS304 or SS316L, these slot filter nozzles offer mechanical strength and corrosion resistance under challenging conditions. Core Functions in Ion Exchange Systems • Resin Retention & Flow Distribution Installed at the bottom or middle plate of an ion exchange vessel, these slot nozzles ensure even resin distribution, uniform backwashing, and effective flow control—vital to prevent channeling. They are distributed across vessels via hub and header systems or nozzle configurations. • Resin Trapping At the system outlet, resin trap strainers serve as a safety net, capturing escaped resin beads to protect downstream components, such as pumps or membranes. Key Advantages of Wedge Wire Nozzle Strainers • High Flow Efficiency: Large ope...

The stationary hydrosieve , also widely known as a static wastewater screen or a sieve bend screen , is the most trusted and simple solution for liquid-solid separation in wastewater treatment fields. This non-powered equipment plays a critical role in pre-treatment, effectively removing solids to protect downstream systems and improve overall process performance. T he Science Behind the Static Screen A stationary hydrosieve operates on a simple, yet highly effective principle based on the Coandă effect. The unit consists of a curved, parabolic screen, typically constructed from durable stainless steel. This curved screen features a series of triangular or V-shaped wedge wires. As wastewater or process fluid flows over the inclined surface, the liquid adheres to the curved screen bars due to surface tension and the velocity of the flow. The design creates a controlled hydraulic action: • Deceleration of Screenings: The curve of the screen slows the solids, allowing them to tumble and ...

A Coanda screen is a specialized wedge wire intake screen designed to separate water from debris such as leaves, sediment, and aquatic life. It is installed at water intakes—such as rivers, streams, or dam outlets—to provide clean, filtered water for downstream applications. Coanda screens are an innovative solution widely used in hydropower plants, irrigation systems, water intake structures, and wastewater treatment facilities. Known for their self-cleaning ability and efficiency in filtering debris, they rely on the Coanda effect—a natural hydraulic principle that allows water to adhere to a curved surface. The Coanda Screen Working Principle So, how does a Coanda screen work? ▪ Water Flow Over the Weir Water is directed over a sharp crest or weir and flows onto the screen surface. ▪ The Coanda Effect in Action Due to the Coanda effect, the water clings to the curved screen surface, following its slope rather than separating immediately. ▪ Separation of Water and Debris Water pass...

Wastewater treatment relies on robust and efficient screening systems to remove solids before biological or chemical processing. Among the most dependable options available is the Stationary Hydrosieve , also known as a static wastewater screen or sieve bend screen .  Unlike mechanical bar screens or r otary drum filters , the hydrosieve wastewater screen has no moving parts, making it an energy-efficient and low-maintenance option for a wide range of applications. Wastewater flows over a curved parabolic wedge wire panel, allowing liquids to pass through while retaining solids on the screen surface. Its simple yet effective design has made it a trusted solution for municipal plants, industrial facilities, and food processing wastewater treatment. YuanLv Stationary Hydrosieve Key Benefits • Durable Materials - Built with stainless steel wedge wire, resistant to corrosion and wear. • Non-Clogging Efficiency - The V-shaped wire profile prevents blockage and ensures continuous ope...

Mining operations rely heavily on precise separation and dewatering processes. The right screening equipment not only improves efficiency but also extends service life and reduces maintenance costs.
