Description

Ceramic sand filter is widely used in the single layer filtering pool,multi-layer filtering pool and mechanical filter,to deal with various industrial water,city tap water,city sewage,pure water,soft water,and act as biologic filter to treat organic sewage.Moreover,It can deal with various industrial dust and soot of boiler.Because of the accession of anti-corrosive rare earth in the lanthanide and actinide series,apart from the performance of common ceramic sand,the performance in anti-corrosion is further improved,and contain more stable SiO2,particularly suitable for chemical water treatment in boiler and producion of super pure water.
