Fiber Ball Filter Material with Strong Absorption Capacity

Fiber ball filter material acts as a physical filtration medium to remove contaminants from water through interception, impingement, adsorption and bioremediation.

The balls are composed of cross-linked polyester fibers woven into a porous 3D matrix with countless interstitial spaces. During the filtration process, water flows through these gaps between fibers.

Suspended solids that are larger than the pore sizes become strained out as they cannot pass through. These particles accumulate on the fiber surfaces or within the matrix, slowly forming a cake layer for additional screening.

Meanwhile, dissolved and colloidal substances below the pore sizes are attracted to and bond onto the immense internal fiber surface area through forces like van der Waals attraction and chemical binding.

Various contaminants such as metals, organics and microbes are removed via different attachment mechanisms based on their properties. The omnipresent fiber network provides a vast adsorptive landscape.

Trapped within the labyrinth of crisscrossing fibers, water gets exposed to contamination for extended contact time, maximizing chances for impurities to be sequestered instead of passing through untreated.

The complex 3D structure also cultivates diverse aerobic and anaerobic bacterial biofilms that colonize the fiber exteriors. These microbial communities further break down and digest residual organic pollutants.

Eventually, purified water permeates the entire fiber ball volume and emerges clear on the downstream side with a much lower level of total dissolved solids achieved through a multipronged physical, chemical and biological purification process.

Fiber balls can be backwashed to release and rinse away accumulated particles and sloughed biofilms for re-use, retaining their porous habitat and high-performance remediation abilities over a long service lifetime.
