The natural quartz sand filter material produced by our factory is selected and manufactured from the high-quality sea sands of Xiamen, a coastal area of southern Fujian. After a thousand years of wave impact, the sand in the South Fujian Sea is full of particles, translucent, and not easily crushed. The sample analysis results of the Zhongnan Municipal Design Institute commissioned by the Ministry of Construction’s “Filter Media” Ministry Marking Committee are: proportion 2.63, silicon content 97.8%, mud content 0.13%, wear rate 0.1%, hydrochloric acid dissolution rate 0.67%, and organic matter shallower than the United States K_2Cr_2O_7 The standard colors and quality meet the ministerial standards.
