Initially, fiber balls were developed solely for filtering oil from water without considering service life, so the service life of early products was usually within 2 years. Due to the lipophilic and hydrophobic properties of the original fiber filaments, oil stains attached to the surface of fiber balls were difficult to completely remove during the backwashing process of fiber ball filters, thereby shortening their service life.
Later, based on feedback from numerous customers, we collaborated with fiber manufacturers to conduct technical improvements on the fiber filaments, optimizing their characteristics from lipophilic and hydrophobic to hydrophilic and oleophobic. This improvement significantly enhanced the service life of fiber balls: oil stains on the surface can be efficiently stripped during backwashing, extending the product's operational cycle remarkably.
Thanks to the high density of the fiber filaments and the small mesoporous structure of the fiber balls, fiber ball filters adopt pressure filtration, achieving an oil removal rate of up to 98.9%, which fully meets drainage standards. Through the above introduction, you must have understood the oil removal principle of fiber balls! Here is a simple example: everyone owns a car, and when there is a problem with the car, it needs to be repaired in a timely manner.
During the first maintenance, maintenance personnel will wipe the engine oil with toilet paper to clearly identify faults. However, toilet paper is prone to tearing and sometimes sticks to the engine surface, causing cleaning difficulties.
Later, auto repair shops switched to cotton-linen cloth, which can not only wipe off engine oil without leaving traces but also has the drawback that oil stains on the cloth are extremely difficult to clean, making it essentially a one-time use item. Such fiber products possess lipophilic and hydrophobic properties-similar to how fiber balls work in filters: pressure filtration compresses the fiber balls tightly, allowing them to adsorb oil stains through their lipophilic properties while enabling smooth water flow via their hydrophobic properties, realizing the entire process from initial oil adsorption to subsequent oil interception.
In contrast, the improved fiber balls, even if oil stains adhere to their surface, can be easily stripped through backwashing, which not only extends the service life but also reduces the operational cost.
