Spherical Shell Filtration Media Floating Suspended Bio Filler Ball for Water Treatment
Also known as porous rotating spherical suspended packing, this is a new material developed for domestic sewage treatment and biofilm process technologies. It features a fully three-dimensional structure, large specific surface area, direct placement without fixing, easy biofilm formation, and non-clogging properties in biochemical wastewater treatment.
Suspended Spherical Packing
Sludge-free suspended spherical packing is an advanced material developed based on numerous sewage treatment packings. It serves as a biofilm carrier while also intercepting suspended solids, offering advantages such as strong bio-adhesion, large specific surface area, high porosity, chemical/biological stability, durability, non-toxic leaching, UV resistance, anti-aging, and superior hydrophilicity-outperforming traditional soft, semi-soft, composite, and elastic packings.
Core Structures: Melon slice type, composite type, elastic filler, snake skin filament, sponge, fluidized bed, volcanic rock, etc.
