The Coagulation Dehydration Separator, also known as the oil-water filter separator or jet fuel filter separator, is a revolutionary piece of equipment for purifying fine chemical raw materials. With its unique design and powerful capabilities, it filters out the finest particles and effectively removes water content, fiber, and suspended substances from the medium.**Unique Design** It features two types of filter cartridges - the coagulation filter cartridge (primary filter) and the separation filter cartridge (secondary filter), housed in a sturdy metal shell. Additional accessories like dirt drainage valves, water drainage valves, differential pressure gauges, safety valves, and heating devices enhance its functionality.

**Versatile Applications** This separator is widely used in various industries, including aviation (military fuel depots, aerospace kerosene storage areas, aircraft refueling tank trucks), oil refineries, factories, docks, and oil pipelines. It can handle low viscosity hydraulic oil, lubricants, aviation fuel, gasoline, kerosene, diesel, and more.**Filtering Process** The medium passes through two levels of filtering. First, it goes through the coagulation filter cartridge made of composite fibers, which captures particulate impurities. Then, water in the medium coalesces and settles in a collection basin. Smaller water droplets enter the separation filter cartridge for further treatment. **Filter Cartridge Replacement** The frequency of filter cartridge replacement depends on factors such as the quality and volume of the medium, the level of impurities, and operating conditions (pressure and temperature). Signs of needing replacement include increased differential pressure, reduced system efficiency, visible damage to the cartridge, and deterioration in the quality of the filtered medium.**Evaluating Performance** After replacing the filter cartridges, improvements can be evaluated by observing a decrease in differential pressure and an improvement in the purity of the processed medium. **Impact of Factors on Lifespan** The type of filter cartridge, environmental conditions, operating temperature and pressure all influence the lifespan of the filter cartridges. Higher quality cartridges, cartridges designed for harsh environments, and those with larger surface areas may last longer. Regular inspections, integrity tests, and particle counting can help assess the condition of the filter cartridges.**Common Filter Materials** Filter cartridges can be made from materials like polypropylene, activated carbon, ceramic, resin, and membrane. Each material has its own advantages and replacement frequencies.**Advanced Technology** Innovations like back-washable filters and End of Service Life Indicators (ESLI) can extend the lifespan of filter cartridges by allowing for cleaning and reuse, and providing accurate replacement timing based on usage and contamination level.
