Crafted with precision, the filler series is manufactured from polypropylene injection and features a sophisticated design of inner and outer double spheres. The outer sphere is a hollow fish mesh, while the inner sphere rotates,
serving primarily as a biofilm carrier and intercepting suspended solids. It flaunts strong biological adhesion, an expansive surface area, and high porosity,
ensuring exceptional chemical and biological stability. It is robust and durable, does not leach harmful substances, and prevents secondary pollution. With its ultraviolet resistance, anti-aging properties, and superb hydrophilic nature,
it effortlessly facilitates easy generation and replacement during use, while offering resistance to acids and alkalis. Its anti-aging characteristics and immunity to water flow extend its service life, resulting in minimal residual
sludge and ease of installation.
