Fiber Ball Filter Material in Filtering Water

XINKAY water treatment Co., Ltd. supplies durable filter media for municipal drinking water treatment facilities. Our anthracite multimedia filter effectively removes multiple contaminants from raw water sources through a symbiosis of physical, chemical and biological purification mechanisms.

Comprised of various graded anthracite aggregates combined with a layer of silica sand, the complex structure of the multimedia filter provides immense surface area for adsorption and colonization. As water permeates the media bed, suspended solids and particulates are strained out between heterogeneous grains. Meanwhile, a diverse pool of functional groups on the anthracite surface attracts dissolved compounds like harmful bacteria, viruses, heavy metals and minerals via electrostatic force or Van der Waals interactions. Over time, a naturally established biofilm accumulates within porous voids, metabolizing any remaining biodegradable organic pollutants.

Notably, the anthracite multimedia filter excels at purifying water for human consumption. It can consistently reduce turbidity and suspended sediment loads to meet stringent clarity standards. By streptococcal adsorption tests, the treated water reliably passes bacteriological quality for distribution. Furthermore, the multilayer composition facilitates easy and infrequent backwashing, prolonging filter run times. The processed water also tests low for hardness due to calcium and magnesium retention in the anthracite.

Through a balanced combination of physical filtration, adsorption chemistry and microbiology, our multimedia filter ensures reliable potability compliance from source waters of variable quality. It delivers clean, safe drinking water day after day.
