Multi-tank automatic backwash water treatment equipment

Product introduction

Side Filter (Shallow Sand Filter) is a high-performance deep-bed filtration system widely used in 

industrial circulating water, water supply, and wastewater filtration applications. This advanced filtration solution, 

represented by HGBMF's media filtration system, utilizes deep-bed filter media to effectively remove particulate 

matter and significantly reduce turbidity from process water streams. The Side Filter (Shallow Sand Filter) 

employs a unique fluidization mechanism that ensures thorough cleaning of the filter media, 

maintaining consistent filtration performance over extended operating periods. When loaded with

 specialized filter materials such as activated carbon or zeolite, the Side Filter (Shallow Sand Filter) can 

also adsorb and remove corresponding organic compounds, ions, and other dissolved contaminants,

 providing multi-functional water treatment capability. The fluidization device (bottom drainage system)

 within the Side Filter (Shallow Sand Filter) fluidizes the filter medium, effectively dislodging trapped pollutants 

and discharging them from the system, ensuring complete media regeneration and restoring full filtration capacity. 

With its robust construction, automated operation, and versatile media options, the Side Filter (Shallow Sand Filter) 

represents a reliable and cost-effective solution for industrial water treatment requirements.

Side Filter (Shallow Sand Filter) operates on well-established filtration principles that deliver consistent water quality. 

During the filtration state, pressurized water flows into the water distribution system through the inlet of

 the Side Filter (Shallow Sand Filter) tank and is uniformly distributed across the filter media layer. 

As water passes through the media bed of the Side Filter (Shallow Sand Filter), suspended solids and 

particulate contaminants are effectively intercepted and retained by the filter material through a combination

 of mechanical straining, gravitational settling, and adsorption mechanisms. At the bottom of the Side Filter

 (Shallow Sand Filter) is a precision-gap water collector that evenly collects the filtered water and discharges

 it from the filter outlet. The precisely engineered gaps on the collector of the Side Filter (Shallow Sand Filter)

 effectively prevent the loss of filter media, ensuring long-term media retention and consistent filtration performance.

 Mechanical actuators (pneumatic or electric) control the water flow through the Side Filter (Shallow Sand Filter),

 providing reliable and automated operation with minimal operator intervention.

Side Filter (Shallow Sand Filter) features an automatic backwash function that ensures continuous, 

uninterrupted operation. When the Side Filter (Shallow Sand Filter) is in the automatic backwash state,

 the backwash cycle is triggered by an increasing pressure differential across the media bed. As impurities 

continuously accumulate within the filter media layer of the Side Filter (Shallow Sand Filter), 

the pressure loss gradually increases. When the pressure differential reaches a predetermined set value, 

the Side Filter (Shallow Sand Filter) automatically switches to the backwash state without requiring manual intervention. 

Pressurized water enters the filter media layer through the fluidization device (the water collection system) of

 the Side Filter (Shallow Sand Filter), creating a scouring action that dislodges trapped pollutants from the media surface.

 The dislodged contaminants are then discharged from the Side Filter (Shallow Sand Filter) system through the waste outlet. 

After the backwash cycle of the Side Filter (Shallow Sand Filter) lasts for a minimum of 2 minutes, 

the valve system automatically returns the Side Filter (Shallow Sand Filter) to the filtration state, 

ensuring minimal interruption to the water treatment process.

Side Filter (Shallow Sand Filter) offers exceptional versatility through its ability to utilize various filter

 media for different treatment objectives. The standard media configuration of the Side Filter (Shallow Sand Filter)

 uses carefully graded sand or quartz media for effective suspended solids removal and turbidity reduction. 

When the Side Filter (Shallow Sand Filter) is loaded with activated carbon media, it provides excellent adsorption 

of organic compounds, chlorine, and taste/odor-causing substances. When zeolite media is used in the Side Filter

 (Shallow Sand Filter), it offers enhanced removal of ammonia, heavy metals, and certain ionic contaminants. 

This media flexibility of the Side Filter (Shallow Sand Filter) allows system designers and plant operators to customize

 the filtration system to meet specific water quality challenges. The Side Filter (Shallow Sand Filter) can be configured

 as a single unit or as multiple units operating in parallel, providing scalable filtration capacity that grows with your

 operational requirements.

Side Filter (Shallow Sand Filter) is constructed with durable materials and components that ensure long-term 

reliability in demanding industrial environments. The tank of the Side Filter (Shallow Sand Filter) is manufactured

 from corrosion-resistant materials that withstand exposure to aggressive process fluids and environmental conditions. 

The internal water distribution and collection systems of the Side Filter (Shallow Sand Filter) are precision-engineered 

to ensure uniform flow distribution and prevent channeling or bypass, maximizing the utilization of the filter media bed.

 The control valves and actuators of the Side Filter (Shallow Sand Filter) are selected for reliability and long service life, 

minimizing maintenance requirements and ensuring consistent automated operation. The Side Filter (Shallow Sand Filter)
