Sand filter is a kind of fluid treatment equipment with a wide range of uses, and its main function is to remove suspended substances, chromaticity, odour and bacteria in water. Sand filter is made of multi-layer quartz sand and stone aggregates of different particle sizes as filter media, separating and filtering impurities in water through highly efficient physical action, so as to make the water clearer and achieve disinfection and purification effect, which is widely used in the fields of tap water purification, industrial wastewater treatment and drinking water purification.
The specific use of sand filter:
Irrigation water filtration
Irrigation water used in agricultural production also often contains many impurities, such as sand, mud, algae and so on. These impurities can affect the normal growth and development of crops, reduce yields, and cause problems such as land curing and environmental pollution. Through the filtration treatment of sand filters, particles and impurities in irrigation water can be effectively removed to ensure the normal growth of crops, improve the quality and efficiency of agricultural production, and protect the health of farmland and the environment.
Swimming pool water filtration
Swimming pool is an important place for people’s leisure and recreation, but prolonged use will produce microorganisms, dirt and algae in the pool water, which will endanger the health of swimmers. Sand filter can filter the impurities in the swimming pool, keep the water clear and hygienic, avoid swimmers’ symptoms such as skin allergy and cough, and ensure the safety and health of swimming.
Industrial Wastewater Filtration
Many industrial production processes produce wastewater, which, if discharged directly into natural water bodies, will not only pollute the environment, but also cause harm to organisms. Sand filters can remove pollutants such as particles, sediments and microorganisms from industrial wastewater by means of mechanical filtration and biological filtration, reduce the turbidity and COD/BOD value of wastewater, protect the environment, and safeguard people’s life and health.
Benefits of sand filter
Firstly, sand filter can improve the stability of water quality and overall water quality land. The initial stage of the sand filter is prone to substrate to flow, and the new filter media is often mixed with a large amount of air, fine particulate matter, microorganisms and harmful substances inside. However, after a certain period of time, these substrates will be used up, the filtration medium is gradually in a more stable state. This is not only conducive to ensuring the stability of water quality, but also can greatly reduce the burden of the later processes. At the same time, the sand filter can remove turbid substances, water scum and fine particles in the water, and the water quality after filtration shows excellent characteristics such as transparent colour, cleanliness and hygiene.
Secondly, sand filter has good filtering effect on impurities such as germs and fungi. In the sand filter, when the water flows through the filter medium, it can well increase the contact frequency between microorganisms and germs, and at the same time, it can also carry out specific killing treatment for microorganisms and germs, and play a certain disinfection and purification role, so as to make the water quality more hygienic and safe.
Finally, the sand filter has good economic benefits. As the material cost of the sand filter is relatively low, and at the same time, it can reduce the amount of chemical treatment agents, and the maintenance cost is relatively low, and the effect of long-term use is also very significant, therefore, in the water treatment and wastewater treatment, the equipment has been widely used and promoted.
Sand filter in various fields of application is very wide, it has high efficiency, practicality, safety, economy, environmental protection and other characteristics, to become an important and indispensable equipment for modern water treatment and pollution prevention work.
