Glass steel sand filter is an efficient water treatment equipment, which removes suspended matter, microorganisms and other fine particles from water by using different types and particle size granular substances (such as quartz sand, activated carbon, etc.) as filter material. These filter material layers can complete the water filtration and purification process through mechanical filtration, adsorption filtration and biological filtration.
Automatic sand filter is a water treatment equipment with integrated automatic control function, which includes several key components:
1. Water inlet: This is the inlet of water into the sand filter, usually equipped with a valve or control device to regulate the flow of water into the filter.
2. Water outlet: The filtered water flows out through this outlet, which can be directly used for the subsequent water treatment process or direct use.
3. Drain port: When the sand filter is backwashed, the waste water containing impurities will be discharged through this outlet. Backwashing is a regular process used to remove accumulated impurities on the filter material and maintain the filtration efficiency of the filter.
4. Pressure gauge: used to monitor the pressure inside the sand filter. It can help to monitor the working condition of the filter, such as high pressure may mean that the filter material is blocked and needs to be backwashed.
Irrigation principle: Water is pumped from the ground well →
After fertilizer box → centrifugal filter → air release valve → regulating valve → automatic backwash filter → control voltage → water flow into the land
Sand filter, also known as sand filter or sand filter bed, is a common water treatment equipment, mainly used to remove suspended solids, microorganisms, organic matter and other impurities in water. The working principle of the sand filter is mainly based on two mechanisms: physical filtration and biological filtration:
1. Physical filtering:
Screening action: The sand layer in the sand filter is composed of sand particles of different particle sizes, forming a porous medium. When water flows through the sand, larger particles are trapped on the surface or inside the sand because they cannot pass through the small holes between the sand grains.
Adsorption: The surface of the sand has a certain adsorption capacity, which can adsorb small particles and colloidal substances in water.
2. Biological filtration: In the sand layer of the sand filter, a layer of biofilm is naturally formed, which is composed of bacteria, protozoa and other microorganisms. These microorganisms can decompose organic matter in water, thus playing a role in purifying water quality.
The formation and maintenance of biofilms require certain conditions, such as suitable temperature, sufficient dissolved oxygen and nutrients.
3. Backwashing: Over time, impurities in the sand layer will gradually accumulate, resulting in a decrease in filtration efficiency. In order to restore the filtration effect, the sand filter needs to be backwashed regularly. Backwashing is to reverse the water flow through the sand layer, and wash out the accumulated impurities at a higher flow rate to restore the filtration capacity of the sand layer.
