Overview of Quartz Sand

Quartz sand, used for water filtration, is a common type of stone found in nature, often located near rivers and streams. After gradual erosion by water, their surfaces become rounder and smoother.

Characteristics of Quartz Sand for Water Filtration

• Quartz sand is widely used in water filtration due to its superior properties.
• It has high compressive strength, long-lasting durability, and good chemical stability.
• Quartz sand is insoluble in water and does not react with chemicals, ensuring purity and safety for filtered water.
• Moreover, the size and shape of quartz sand can be adjusted to optimize filtration efficiency.
• Quartz sand can filter out small impurities such as organic matter, microorganisms, and harmful chemical compounds.
• Notably, quartz sand can be reused multiple times after cleaning, reducing costs in the water filtration process.

Toan A provides quartz sand in various sizes from 1 - 2 mm; 4 - 8mm; 8 - 20mm to meet all needs.

Technical Specifications of Water Filtration Quartz Sand

To understand the technical characteristics of quartz sand for water filtration, you can refer to the data table below.

Water filtration quartz sand typically has a size greater than 2mm. They are relatively uniform in size and have high hardness. The basic components include:

• The main component is Silicon Dioxide (SiO2) at around 99.4%.
• Additionally, there are other components such as Aluminum Oxide (Al₂O₃) 0.1%, Iron Oxide (Fe₂O₃) <0.1%, Sodium Oxide (Na₂O) 1%.

Applications of the Product

Quartz sand comes in various colors and sizes, making it easy to find and extract. Therefore, this type of sand can be used in many aspects of our lives, such as:

• In landscaping and aquarium design: used for decoration, embellishment of plant pots, aquariums, and aquatic tanks to make them more lively and attractive.
• In the maritime industry: Large quartz stones can be used as ballast for ships.
• In the construction industry: Quartz sand can be used as a material in building construction.
• In water filtration: Used in various sizes to remove impurities in water, providing clean pure water.

Usage Recommendations

• Do not use quartz sand that is contaminated or shows signs of damage.
• Avoid exposing quartz sand to strong chemicals or corrosive substances.
• When backwashing, rinse with strong water flow for 10-15 minutes to ensure thorough cleaning of the sand.
