- Gravel used in water treatment, water purification. Quartz Gravel work to filter suspended

components of size small particles are unable to precipitate when deposited naturally.

- During the filtration process, on quartz gravel surface will create a filter layer to support the

filtration process, especially when Fe (OH)³ precipitate on quartz gravel surface will help adsorb

arsenic when water sources are at risk of arsenic contamination.

- Quartz Gravel is a very good agent in keeping the precipitate of high viscosity cotton which is

difficult to separate and difficult to filter.
