What is quartz pebbles? Their use in water filtration
Quartz gravel (support gravel) , like quartz sand, is a quite popular water filtration material today. It combines with quartz sand to support this sand layer, which has the role of filtering water, removing small solids or suspended components that do not precipitate out of the water.
The purpose of using quartz gravel in the water collection and filtration process is because quartz gravel has a large and fairly uniform particle size, high particle gloss, high hardness, good abrasion resistance, and is used in the process of collecting and filtering water. Water filtration process. During this process, quartz gravel can be combined with quartz sand, activated carbon,... and some other filtering materials to help remove iron and heavy metals in water.
To avoid clogging of water collection pipes and to ensure the best quality of output water, replace the gravel layer every 6-12 months.
Quartz gravel is commonly used due to its low price and ability to support water filtration materials. Uses are similar to quartz sand.
Basic ingredients
» 99.4%Silicon oxide content (SiO2)
» 0.1%Aluminum oxide content (Al2O3)
» Less than 0.1%Iron oxide content (Fe2O3)
» 0.1%Sodium oxide content (Na2O)
Uses of quartz gravel in water filtration systems.
Quartz pebbles are exploited for application in many fields.
- In the water filtration system, quartz gravel acts as a shelf to support quartz sand, activated carbon, manganese...
- Has the effect of preventing and removing suspended substances and small foreign objects that exist in water and are unable to self-precipitate.
- Quartz gravel combined with quartz sand are materials that are very effective in removing arsenic.
- Quartz gravel holds flocculent precipitates, suspended oils and viscosities, and is unable to self-settle when in water.
Advantages of quartz pebbles
- Quartz gravel is available in nature so it is cheap and saves money.
- The small size of gravel makes it easy to exploit, process, package and transport.
- Quartz gravel when combined with quartz sand, manganese, coconut shell activated carbon... will produce a clean water source for drinking, living, and production.
- Easy to clean, reusable.
Quartz gravel position in water filtration system
Each layer of quartz sand has a thickness of 10-15 cm. Quartz gravel is used in water filtration and is specialized for domestic and industrial well water treatment. The filter material is quite uniform in size, has high air permeability, helps water pass through easily and helps retain solid residue and small suspended solids in the water. Quartz gravel is combined with yellow sand, quartz sand, activated carbon and manganese sand to help filter water more cleanly and the output water quality reaches drinking water quality.
Recommended use
» Should be combined with manganese sand filter to remove suspended sediment from water.
» The minimum thickness of the supporting gravel layer is 0.2m (covering the output water collection pipe).
» Regularly rinse and backwash to avoid clogging of the output water collection pipe.
» Stones should be replaced every 6 to 12 months.
