GEL filter Germany GEL model GEL price

GEL filters are widely used in industrial and commercial fields, such as food, textiles, metallurgy, plastics, pharmaceuticals, building materials, papermaking, HVAC systems for industrial and commercial buildings, irrigation, wastewater treatment, sewage regeneration, municipal water supply, waterworks, large power plants, chemical enterprises, and emergency filtration. The filtration grade is determined by the water quality requirements of the downstream water system or equipment and the specific water usage scenario. They are typically installed at the inlet of pressure reducing valves, relief valves, constant level valves, and other equipment. The filter consists of a housing, stainless steel filter screen, blowdown section, drive mechanism, and electrical control components.

GEL filter principle

The filter element of the electronic water processor disc filter uses discs as the carrier for impurity removal. It is composed of a stack of plastic discs with grooves in different directions on both sides. The edges of the grooves on adjacent surfaces form numerous intersection points, creating many cavities and irregular passages that narrow continuously from the outside in. During filtration, these passages cause turbulence in the water, ultimately causing impurities to be intercepted at the various intersection points. When the discs are stacked on the filter element skeleton, spring and inlet water pressure form a filtration unit that is loose on the outside and tight on the inside. The discs in each filtration unit, compressed by springs and water pressure, form countless fine screens that impurity particles cannot pass through. The disc width is 12 - 16 mm, and the disc material is high-quality engineering plastic with extremely high wear resistance.

GEL filter features

Thorough and efficient backwashing: Since the filtration pores are fully opened during backwashing, combined with centrifugal jet action, it achieves a cleaning effect unattainable by other filters. The backwashing process for each filtration unit takes only 10 to 22 seconds. Fully automatic operation with continuous water output; backwashing is initiated by time or differential pressure control. Within the filter system, backwashing is performed sequentially across individual filtration units and workstations. Automatic switching between operating and backwashing states ensures continuous water output, low system pressure loss, and consistent filtration and backwashing performance over time. Modular design allows users to select the number of parallel filtration units as needed, offering flexibility and strong interchangeability. It makes flexible use of corner spaces, allowing for installation with a small footprint according to site conditions. Simple maintenance requires almost no daily maintenance, inspections do not require special tools, and there are very few detachable parts.

GEL filter testing

When the filter membrane and filter element are completely wetted with a specific solution, pressure is applied from one side via a gas source (our instrument includes an intake control system to stabilize pressure and regulate intake). As pressure increases, gas is released from one side of the filter membrane, manifesting as bubbles of varying sizes and quantities on that side. The corresponding pressure value identified by the instrument is the bubble point. Diffusive flow test principle: The diffusive flow test refers to the state when the gas pressure is at 82% of the filter element's bubble point value. At this stage, significant gas perforation has not yet occurred; instead, a small amount of gas first dissolves into the liquid phase of the membrane and then diffuses from this liquid phase to the gas phase on the other side. This portion of gas is called the diffusive flow. Measuring the diffusive flow value provides a quantitative measure that not only accurately determines the integrity of the filter but also reflects issues such as membrane porosity, flow rate, and effective filtration area. This is why manufacturers abroad use the diffusive flow method to test integrity.
