Special process and properties of elastomeric fillers for water treatment
- Dec 12, 2018 -

The elastic filler used for water treatment screens several high-quality varieties of corrosion resistance, temperature resistance and aging resistance in polyolefins and polyamides. It is mixed with hydrophilic, adsorption, anti-heat and other additives, and special drawing. The yarn-making process is to insert the thread on the corrosion-resistant, high-strength center rope.


Due to the excellent material selection and process formula, the rigidity and flexibility are moderate, so that the filaments are arranged in a uniform and uniform radial state, and the single body of the suspended three-dimensional elastic filler is prepared, and the filler can be uniformly stretched in a three-dimensional manner in the effective region to make the gas, The water and biofilm are fully infiltrated and exchanged.


The biofilm not only can be uniformly implanted on each thread, maintains good activity and void variability, and can obtain a larger specific surface area during operation, and can perform good metabolism for water. This feature and phenomenon of the treated elastic filler is unmatched by other domestic fillers.


Compared with rigid honeycomb fillers, the elastic fillers used for water treatment have large variability and no clogging; compared with soft fillers, the material has a long service life and no sticky joints; compared with semi-soft fillers, the surface area is large. The film is fast and the cost is low. Therefore, the filler can be confirmed as a novel energy-saving novel filler after various hard fillers, soft fillers and semi-soft fillers, and is widely used as a bio-filler in a biological contact oxidation tank and a hydrolysis acidification tank.
