Application scenarios of shallow sand filters

Shallow sand filter, also known as shallow medium filter or sand and gravel filter, is an efficient filtration device that uses quartz sand as the filtering medium. It selectively filters out particles, suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions in water through the particle size of the quartz sand layer, thereby achieving the effect of reducing water turbidity and purifying water quality. Shallow sand filters have a wide range of usage scenarios, mainly including the following aspects:

Application of Shallow Sand Filter in Drinking Water Purification
Shallow sand filters can remove harmful substances and pollutants from water, making it meet drinking standards and ensuring people's drinking water safety.
Application of Shallow Sand Filter in Industrial Water Filtration
In the industrial field, shallow sand filters are often used for filtering oxygen lance water, boiler and heat exchanger water supply in steel plants to remove impurities from water, avoid pipeline and nozzle blockages, and ensure the normal operation of production equipment.
Application of Shallow Sand Filter in Raw Water Treatment
Urban residential areas can use shallow sand filters to filter surface water, lake water, seawater, reservoir water, well water, and urban tap water as water sources, removing sediment, suspended solids, algae, and organic matter from the water and supplying water of different qualities.
Application of Shallow Sand Filters in Agricultural Irrigation
Shallow sand filters are particularly suitable for high flow and high impurity water sources, such as irrigation water for farmland, parks, golf lawns, etc., which can effectively improve the quality of irrigation water and promote crop growth.
Application of Shallow Sand Filters in Aquaculture, Swimming, Water Parks and Other Industries
In these industries, shallow sand filters have the characteristics of energy saving and cost saving. Its unique water replenishment device, water collection device, and unified water tank specifications can evenly expand the medium layer during backwashing without the need for compressed air, effectively backwashing, and requiring less water for backwashing, which can reduce operating costs.
Application of Shallow Sand Filter in Industrial Wastewater Treatment
Shallow sand filters can also be used for industrial wastewater treatment to remove impurities and harmful substances from wastewater, reducing the impact on the environment.
Application of Shallow Sand Filter in Hot Spring Water Treatment
For hot spring water, shallow sand filters can remove impurities and pollutants, improve the quality of hot spring water, and make it more suitable for people's use and enjoyment.
