Hot-selling Pebble Filter Material for Water Treatment

Pebble Filter Material
1.Material:pebbles
2.High mechanical strength
3.For water purification
4.For landscape
pebble filter material for water treatment:
is an aggregation of potassium feldspar, plagioclase, biotite and other ores. It has more ten kinds of essential trace element the human body need.
It has strong mechanical strength and large specific surface area. It is the ideal environmental filter in the pharmaceutical industry, chemical industry, food industry and other fields, at present.
Usage:
1.takes the pebbles(gravel) as the raw material,
2.has pure white and the varicolored two kinds.

Functions:
1.with a high mechanical strength
2.has stable chemical properties
3.has a moderate density
4.is the essential supportting lay of each kind filter material
