Shallow sand filters are devices that utilise a layer of sand to purify water. Their operating principle involves capturing particles, suspended matter, and certain organic compounds within the sand layer as water flows through it, thereby achieving water purification. The selective particle size of the sand layer effectively filters out most impurities while allowing clean water to pass through.
Shallow sand filters find extensive application across multiple sectors, including but not limited to:
Industrial applications: Primarily used for filtering industrial circulating water, potable water supplies, and wastewater. Examples include oxygen lance water in steelworks, and filtration for boiler and heat exchanger feedwater. This effectively removes impurities, preventing pipe and nozzle blockages.
Raw water treatment: Employed for purifying surface water, lake water, seawater, reservoir water, well water, and municipal tap water in residential areas. It removes sediment, suspended solids, algae, and organic matter.
Agricultural irrigation: Particularly suited for high-flow sources with elevated impurity levels, such as irrigation water for farmland, parks, and golf courses.
Aquaculture, swimming, and water park industries: Leveraging its energy-efficient and cost-effective characteristics to provide assured clean water quality for these sectors.

1. Question: What industrial water filters do you mainly produce?
A: Our factory mainly produces self-cleaning filters, security filters, bag filters, sand and gravel filters, fiber ball filters, dirt removers, backwash filters, etc., which are mainly used in industrial water treatment equipment. In addition, we also produce accessories for filters such as filter screens, filter cartridges, filter bags, and other filter elements.
2. Question: What is the maximum processing capacity of the Filter?
A: This filter can achieve a maximum processing capacity of 1000m ³/h.
3. Which type of filter can be used to reduce turbidity?
A: You can use our quartz sand filter, which uses quartz sand as the filtering medium to filter water with high turbidity through a certain thickness of granular or non granular quartz sand under a certain pressure, effectively intercepting and removing suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions in the water.
4. Question: Where is your factory located? How can I get there?
A: Our factory is located in Xinxiang City, Henan Province. It takes 2 hours by high-speed rail from Beijing or fly to Zhejiang Airport, and then we will pick up your team. We warmly welcome you to visit us anytime.
5. Q: What is the installation method of the filter?
A: Skid loading and transportation. Just connect the inlet/outlet flange and drain it.
6. Question: Can you customize products?
Of course, if you can provide us with detailed specifications or drawings. Our mission is to inspire customers with ideas about our products and provide satisfactory solutions.
