1, high filtration efficiency: the granite stone filter has a large stone particle size, which can filter out most impurities and pollutants in water, such as sediment, suspended solids and organic matter.
2. Strong durability: Granite stone has high hardness, high compressive strength, is not easy to wear and deform, and can maintain the filtering effect for a long time.
Granite filter is a common water treatment equipment to remove impurities and pollutants from water.
