Technical indicators of quartz sand filter material and precautions when using
1. Overview of quartz sand filter material
Zhengzhou Tianhe quartz sand filter material is made of natural quartz ore, which has been crushed, screened, washed, dried, and filtered. Multi-angular, nearly spherical, low impurity content, high mechanical strength, strong dirt interception ability, and stable chemical properties. Widely used in drinking water, sewage and industrial water.

3. Precautions when using quartz sand filter material
During the process of laying filter material , when paving the bottom layer of supporting material, care should be taken to avoid damaging the water distribution system of the filter. The supporting materials to be installed should be lifted into the pool, then spread or filled with water to the top of the drainage channel, then evenly spread the materials into the water, and then drained so that the water surface drops to the level of the top surface of the layer, and spread with a shovel Evenly, paving personnel should not stand or walk directly on the supporting material, but should stand on wooden boards to operate. The number of operators in the pool should be as small as possible to avoid causing the movement of the supporting material. After the next layer of paving is completed, the upper layer of supporting material can be paved.
It should be noted that the thickness of each layer of supporting material should be accurate and uniform. Use a shovel or scraper to scrape the surface so that it is close to the horizontal plane. The height should coincide with the horizontal line marked by the paving height mark.
After paving the supporting material with a particle size range equal to or smaller than ~, the upper limit flushing intensity of the filter should be used for flushing. Before stopping flushing, the flushing intensity should be gradually reduced to complete effective hydraulic classification and allow light substances to rise to the surface of the supporting material. Drain again and scrape off light materials.
After all the supporting materials are laid in layers, use the method of spreading materials evenly from the top of the pool into the water, and sprinkle in the expected amount of quartz sand filter material (including light materials that should be scraped off and particles smaller than the specified lower limit) diameter fine particles). Then rinse, and then scrape off light materials and particles smaller than the specified lower limit. If the thickness of the filter material does not reach the specified value after operating according to the above method, the above operation should be repeated until the requirements are met. If it is a double-layer or three-layer filter material filter, the upper layer of filter material should be installed only after the lower layer of filter material is washed and scraped off light substances and particles smaller than the specified lower limit. After the anthracite filter material is put into the filter, it should be soaked in water before flushing and scraping.
4. Packaging, storage and transportation of quartz sand filter materials
Quartz sand filter materials and triangular stone supporting materials should be packed and transported in durable fabric bags. For stone supporting materials with larger particle size, the packaging requirements can be appropriately reduced.
The packaging quality of each bag of stone sand filter material and gravel supporting material is.
During transportation and storage, the packaging bags of quartz sand filter media and triangular stone supporting materials should be prevented from being damaged to avoid leakage or inclusion of debris.
. Quartz sand filter material should not be stacked together with supporting materials and other filter materials.
, quartz sand filter material and gravel supporting material should not be stacked together with other materials.
