Automatic Shallow Sand Filter for Removing Suspended Solids

Product Description

Product Description
Shallow sand filters are mainly used for filtering circulating water, water supply, and wastewater in the industrial field. The media filtration system of HGBMF utilizes deep media to effectively remove particulate matter and reduce turbidity. If specific filter materials are installed, such as activated carbon, zeolite, etc., they can also adsorb and remove corresponding organic compounds, ions, etc. The fluidized device (bottom drainage device) in the system can fluidized the filter medium, remove pollutants trapped on the medium, and discharge them thoroughly for cleaning.
Working principle
Filter status:
When the system is in a filtering state, the raw water is evenly distributed through a unique water distributor, and the water passes through the packing layer inside the filter in a laminar flow state. There are multiple evenly distributed water collectors at the bottom of the filter, which collect and extract the filtered water evenly. Horizontal flow filtration can enable the filter to achieve good filtering effect even at high flow rates.
Backwash status:
Impurities continue to accumulate in the packing layer, and the internal head loss continues to increase. When the pressure head loss of the inlet and outlet reaches the set value, the system starts the automatic flushing valve, causing one standard sand cylinder to switch to the backwash state. The backwash time is 1-3 minutes. At this time, other standard unit sand cylinders in the system are still filtering, and the filtered clean water is used to backwash the standard unit sand cylinder, while the rest is still sent to the user; The backwash wastewater is discharged through the backwash drainage outlet of the automatic valve. After the backwash is completed and the pressure head loss inside the standard unit sand cylinder is reduced to a reasonable range, the unit sand cylinder returns to the filtering state, and the next standard unit sand cylinder enters the backwash state. All sand cylinders are cleaned sequentially, and the system returns to the filtering state.

The backwash system has three modes: manual, semi-automatic, and fully automatic, which can be started through manual buttons, internal clock, PLC, pressure differential, or management system. The backwash time can be adjusted and is set to 3 minutes at the factory. There is a timer inside the system that can be used to set the most suitable backwash time for specific process conditions. By designing special controllers, high demand control such as centralized or remote control can be achieved.The filtering system can be installed in different ways. The HGBMF filter can be used as an independent filtration system, utilizing the existing water supply pump in the process. Of course, if it is used as a side filter, it can also be equipped with its own pump separately. The HGBMF filter can also have multiple processing units installed on a common pipeline, allowing for unlimited filtering capacity of the system.All filter media in Lefilter are carefully selected, washed, and dried, with a minimum filtration accuracy of 0.45 microns. Homogeneous high-performance filter material combined with specially designed filters for water distribution above and below ensures that HGBMF can achieve excellent filtration performance even at high flow rates.The overall system of shallow sand filter has complete internal pipelines and control interlock lines before leaving the factory. Installing the system only requires connecting peripheral pipelines and power supply, making installation convenientFactory Display
FAQ
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 self-cleaning filter? What is the range of accuracy?
A: This filter can achieve a maximum processing capacity of 10000m ³/h and a filtration accuracy of 50-3000 microns.
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.
