As human society continues to develop and industrialize, the quality of water environment is rapidly deteriorating, leading to increasing water scarcity. This burden on cities has created a series of ecological and environmental issues that threaten urban survival and development. It is therefore crucial that we prioritize the purification of industrial water in order to protect existing clean water resources and meet the needs of industrial production and recycled water.
Filtration plays a vital role in water treatment, with reverse osmosis (RO) and ultrafiltration (UF) systems being the main solutions for this process. Pre-treatment is also essential. PULLNER offers a wide range of filter cartridges and filter housings, providing comprehensive filtration solutions for various applications.
Our high-flow filter cartridges, along with condensate water filter cartridges, are commonly used in power plant water treatment. Different precision filter elements are employed for initial and operational condensate water filtration. Our products feature multi-layer pleated filter membrane, heat welding, and large diameters, resulting in high flow rates and filtration efficiency. This effectively enhances the filter cartridges' resistance to pressure and extends their lifespan.
Designed for applications requiring high flow rates, this filter cartridge can handle an impressive 110 cubic meters of fluid per hour. The high throughput capability allows for reduced cartridge usage and minimizes filtration equipment size, ultimately leading to cost savings.
This series of filter cartridges comes in polypropylene, glass fiber, and polyester materials, offering versatility for a wide range of fluid filtration conditions. They feature a wide range of micron ratings from 1 to 100 microns, available in 40" and 60" sizes, and come with a lifting handle design for easy installation.
Pullner presents the innovative high dirt holding pleated filter cartridges, designed for demanding industrial filtration applications. Crafted with a multi-layer nanofiber structure and a multi-granular pore size design, these pleated filter cartridges excel at handling high-suspension particles, colloids, and high-viscosity liquids.
Our string wound filter cartridges are meticulously crafted using specific techniques, featuring tightly wound textile fibers (polypropylene, cotton, or glass fiber) around a porous framework (PP or SS core tube), creating a honeycomb structure. This design efficiently filters out suspended particles, rust, and other impurities, all while minimizing pressure drop and maximizing dirt holding capacity.
Our fiberglass reinforced plastic (FRP) membrane housing is specifically designed to accompany high-flow filter cartridges, catering to industries that demand corrosion-resistant filtration solutions. It's the ideal solution to challenges posed by corrosive liquids, offering improved performance and resistance to corrosion, leakage, and detachment. Our single-core filter design allows seamless integration with ultrafiltration and reverse osmosis systems, while other multi-core configurations suit various on-site needs.
