Why? Quartz sand Appearance and Refined quartz sand Different filter materials? The refined quartz sand filter material is white, beautiful and elegant in appearance, crystal clear, and can shine in the sun. Many ordinary quartz sand filter materials are pale yellow in appearance. In fact, the difference in appearance is related to raw materials and manufacturing process.

Quartz sand filter material can often distinguish ordinary quartz sand from refined quartz sand, first because its appearance is very different. The second is the manufacturing process. General pollution Water treatment quartz sand It only needs simple processing technology such as crushing and drying.

The raw quartz sand used for general quartz sand is also different from refined quartz sand. The surface layer is generally yellow skinned quartz sand. The iron ore without impurities on the surface layer is immediately produced and processed into refined quartz sand, but the quality of iron ore is poor. After acid pickling and passivation of refined quartz sand, its pale yellow surface is melted and cleaned after acid pickling and passivation, and its appearance is transparent, beautiful and generous.

Naturally, the price will be slightly higher than that of ordinary quartz sand filter material. The price of one ton of refined quartz sand is several hundred pieces higher than that of ordinary quartz sand. The refined quartz sand filter material is more suitable for deep filtration of drinking water or water body. Generally, quartz sand is mainly used for wastewater foundation cushion.

Sand blasting quartz sand The filter materials shall be piled up with the raw materials of supporting facilities and other filter materials. Quartz sand filter materials and other filter materials shall not be piled up with other harmful substances and pollutants. It cannot be stored outdoors. It shall be stored in the way of anti pollution and pollution treatment. If stored outdoors, the packaging bag will be weathered for a long time until the plastic fragments of the packaging bag are mixed into the quartz sand, seriously affecting the actual effect of filtering.
