Filter cartridges for automatic backwash
The stainless steel Johnson screen tube (reverse construction type, radial external wire) is an innovative filtration component characterized by a unique structural design: the smooth side of the V-shaped wires faces inward and is welded to radial support bars located inside the screen tube, forming a reverse configuration where the support bars are inside and the wires are outside. During filtration, the fluid to be treated flows from the inside of the screen tube from the inside to the outside through the wire gaps, with impurities retained on the inner wall and clean fluid collected and discharged from the exterior. This design is optimized for demanding applications requiring high-efficiency interception, easy cleaning, and clog resistance.
Wedge Wire Resin Traps
Stainless Steel Johnson Screen Resin Traps (or Wedge Wire Strainers) are precision filtration devices specifically designed to intercept and recover granular media such as ion exchange resin or activated carbon. Their core component is a screen pipe or filter basket manufactured using wedge wire winding and welding technology, installed within pipeline systems or at vessel outlets. Their primary function is to prevent the accidental loss of valuable process media (e.g., resin) during backwashing or operation, while simultaneously protecting downstream sensitive equipment (e.g., pumps, valves, membrane elements) from damage caused by particle abrasion. They act as the "safety guardians" in water treatment and chemical processes.
Wedge Wire Candle Filter Elements
Stainless Steel Johnson Screen Candle Filter is a vertical, multi-element, precision surface filtration system. Its core filtering components are "candle-shaped" filter elements manufactured using wedge wire winding and welding technology. Multiple Johnson filter candles are suspended vertically and fixed to a tube sheet within a pressure vessel housing. The operating principle involves the process liquid flowing from outside to inside through the precise wedge-shaped slots on the candle's surface. Solid particles are retained on the external surface, forming a filter cake, while clean filtrate is collected from the internal channel of each candle and discharged. This system is particularly suited for demanding applications requiring high flow rates, high solid content, precision filtration, or dry cake discharge.
Wedge Wire Lateral Assemblies
Stainless Steel Johnson Screen Laterals/Distributors are core water distribution/collection components in industrial filtration systems. They are constructed using precision-welded V-shaped wedge wire technology, consisting of a main header pipe and multiple lateral pipes (distribution arms). Their primary function is to achieve uniform distribution or collection of fluids (water, chemical solutions, or gases) across the cross-section of a vessel during processes such as filtration, backwashing, ion exchange, or biochemical reactions, while simultaneously retaining media (e.g., quartz sand, activated carbon, resin) to ensure system efficiency and stability.
Johnson Filter Nozzles
The Stainless Steel Wedge Wire Filter Nozzle, commonly known as a Johnson filter nozzle or strainer nozzle, is a precision pipe fitting that integrates filtration, water distribution, and water collection functions. It utilizes the Johnson wedge wire winding and welding technology, where V-shaped profile wires are welded onto a central pipe or support rods to form uniform wedge-shaped slots. Its core function is to evenly distribute incoming water or collect effluent within a filtration vessel (e.g., filter, ion exchange vessel) or reactor, while precisely retaining the support/bed media (such as quartz sand, activated carbon, resin) to prevent its loss.
Johnson Screen Tube
Slot Tube---Radial external wire
These tubes are composed of a surface profile wire that is spirally wrapped around axial support profiles and attached to each other by resistance welding.
