String wound filter cartridges or wound filter cartridge, spiral wound filter elements are made of Polypropylene / PP, absorbent/bleached cotton, or glass fiber wound yarn materials. Inner core materials PP, 304 stainless stee, and 316 stainless steel are available for option. It is decided by the application operation temperature and PH range.
PP string wound cartridge filter, cotton string wound cartridge filter and glass fiber cartridge filter can offer true dept filtration for high dirt holding capacity and extremely low media migration. The main advantage of the string wound filter cartridge is its exceptionally high structural strength, therefore, they can withstand higher PSID and severe operating conditions.
Wound yarn filter cartridges can work very effectively a variety of industrial processing, such as in Pre-RO water treatment, Food & Beverage, Chemical filter solution, waste water treatment, petrochemical process, Electronic & semiconductor etc.
