Analysis of quartz sand filter gravel

Usually used as filter material quartz sand, generally for natural sea sand, river sand lake sand, individual places are also useful artificial mechanism mountain sand. The colors of sand grains are yellow, gray, white so on. Generally, quartz sand material is strong, physical chemical properties ratio is more stable, is one of the most commonly used filter material.

Filtration material, should have stable chemical properties, does affect the quality of filtration water, good mechanical strength, easy to wear fragmentation when used, particles should have enough uniform particle size porosity, etc.. These performance indicators must be determined by analysis.

General analysis of quartz sand filter material side set items are:

1. Physical analysis items include adherent moisture, mud content, screening, density, porosity, wear rate breakage rate, mica light substances, etc.

2. Chemical analysis items include solubility of hydrochloric acid, weight loss by burning, silicon dioxide, ferric oxide, calcium oxide, magnesium oxide, alumina water-soluble sulfide, etc.
