Specifications

Description:

Volcanic hard texture such as natural stone, such as porous honeycomb coated surface , strong texture , decorative, wear-resistant ; heat insulation , sound absorption, with different aggregates , cellular porous , with some insulation, heat insulation , sound-absorbing effect.

Physical Properties

1,Apperance: no sharp granular, water flow resistance is small, clogging, gas distribution uniform water distribution ; surface roughness, biofilm fast ,backwash biofilm difficult to fall off .

2, Porosity: Natural honeycomb porous volcanic rock , is zoogloea optimum environment.

3,Mechanical strength:    By the state quality inspection departments of 5.08 Mpa, the practice proved that can efficiently in different intensity of hydraulic shearing action, service life is much longer other filter material 

4,Density:Density is moderate, backwash easily suspended and not run, can saving energy and reducing consumption.

Note:According to the level of classification of silicon content , Acidic ,Intermediate, Basic, and  Ultrabasic four categories volcanic rocks.

Chemical composition:

Application:

Volcanic is used in construction ,irrigation works ,grinding, adsorption, fresh current, filter material ,barbecue charcoal ,garden scene ,soilless culture, etc. It is also a perfect material used in hot stone therapy, which is good to Promote the body's metabolism.
