Ceramic granule filter
Ceramic granule filter is made of high quality argil.Appending with hole-former and bonder, the granule of spherical shape form after ball grinding,filtering,moulding and calcining.The product has uniform granule,red and brown appearance, flinty and porous surface, interlaced with hole and net as well as strong absorption function.In the water treatment,it has the characteristic of strong capacity in sewage treatment,fast filtering speed,long period and low strength in anti-washing etc.Ceramic granule filter is a new type of filter which can increase the water production,improve the water quality and save the energy loss,therefore an ideal of filtering material in water plant,filtering pool and oil filtering pool in oil refinery.

Ceramic sand filter
Ceramic sand filter has stable chemical performance,including attriction resistance,corrosion resistance,high temperature resistance,large specific surface area,strong sewage treatment capacity,good absorption,uniform granule,appropriate specific weight,and long lifetime.This product 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.

Mirco-hole filtering brick,plate and pipe
 Micro-hole ceramic consist of stone material granule,bonder,hole-former and rare earth anti-corrosioner.By the high temperature calcinations,the connective open air hole with bridge arc shape form on the surface and in the inner side.When the flowing substance pass the air hole,it would bring about various physical and chemical effect on the surface and in the air hole,thus achieve the goal of purification and filter,particular for the liquid filter,gas filter and fluidifing fields.According to the material,this product can be divided into,quartz micro-hole ceramic with high silicon oxide content,improved micro-hole ceramic with high alumina content,and special micro-hole ceramic without silicon.In terms of regulation,it can be fall into pipe shape,plate shape,brick shape,and spherical shape.In accordance with time,it can be divided into high speed,medium speed and low speed.
