Horizontal multi-tank shallow sand filter – modular, auto backwash.

1. Product Introduction

Aite Horizontal Multi-Tank Shallow Sand Filter adopts modular design – flexibly combined according to different flow rate 

and land area. Aite Horizontal Multi-Tank Shallow Sand Filter can use time, pressure difference, and other ways of automatic

 backwash with automatic operation. The filtration units in the system are backwashed in turn, and the effluent is not

 interrupted during backwashing.

Aite Horizontal Multi-Tank Shallow Sand Filter filtration system is lightweight and requires no special foundation treatment. 

It has a small footprint, can be flexibly arranged according to actual situation, and is easy to install.

Aite Horizontal Multi-Tank Shallow Sand Filter is engineered as a fully interchangeable substitute for original

 models – maintaining identical dimensional parameters, interface specifications, and filtration performance to enable direct

 drop-in installation without any housing modifications.

As a professional manufacturer specializing in industrial water filtration equipment, we deliver Aite Horizontal Multi-Tank

 Shallow Sand Filter with stable performance, reliable construction, and competitive pricing for industrial facilities worldwide.

2. Principle of Operation

Aite Horizontal Multi-Tank Shallow Sand Filter operates through the following process:

Filtering State: When the system is in the filtering state, pressurized water flows into the water distribution system from the

 filter tank inlet and uniformly reaches the filter material layer. When water passes through the filter material layer, suspended 

matter is intercepted by the filter material. Water flows through the bottom with a water collector, is evenly collected, 

and exits the filter. The gap on the water collector can prevent the loss of filter material.

Automatic Backwash State: The backwash cycle is controlled by increasing pressure differences and set times. With 

continuous accumulation of impurities in the filter material layer, pressure loss continues to increase. When pressure

 difference increases to a certain set value (or reaches a certain set time value), the system automatically switches to 

backwash state. Pressurized water enters the filter material layer, scours it, and makes the intercepted pollutants fall off

 and discharge out of the filtration system. After backwash lasts for at least 2 minutes, the valve automatically switches the

 system to the filtered state.

3. Backwash Condition

When Aite Horizontal Multi-Tank Shallow Sand Filter running time or operating pressure difference reaches the set value,

 the system enters the backwash state. At this time, the controller sends the backwash signal to the solenoid valve. 

The solenoid valve through the compressed air signal sends air into the pneumatic device. The connecting rod structure 

controls the four ball valves at the same time. The system enters the unwashed state – pressurized water through ball valve

 S3 enters the collection device. Ball valve S4 closed, pressurized water through the collector enters the filter material layer, 

washes it, and makes the intercepted pollutants fall off. Through valve S2 (S1 closed), pollutants enter the discharge pipe.

 Backwash for 2 minutes, then the valve automatically jumps to the filter state.

7. Frequently Asked Questions (FAQ)

Q1: What is the Aite Horizontal Multi-Tank Shallow Sand Filter designed for?

A: Aite Horizontal Multi-Tank Shallow Sand Filter is designed for high-speed water filtration with automatic 

backwashing – removing suspended matter from water for industrial and municipal applications.

Q2: How does the Aite Horizontal Multi-Tank Shallow Sand Filter work?

A: Aite Horizontal Multi-Tank Shallow Sand Filter operates by passing pressurized water through a filter material layer where 

suspended matter is retained. When pressure loss increases to a set value, the system automatically switches to backwash 

state.

Q3: Does the Aite Horizontal Multi-Tank Shallow Sand Filter interrupt water supply during backwashing?

A: No. Aite Horizontal Multi-Tank Shallow Sand Filter does not interrupt effluent during backwashing – the filtration units are

 backwashed in turn, ensuring continuous water supply.

Q4: What backwash control methods are available for the Aite Horizontal Multi-Tank Shallow Sand Filter?

A: Aite Horizontal Multi-Tank Shallow Sand Filter can use time, pressure difference, and other ways of automatic backwash

 with automatic operation.

Q5: How long does the backwash process take in the Aite Horizontal Multi-Tank Shallow Sand Filter?

A: The backwash process in Aite Horizontal Multi-Tank Shallow Sand Filter lasts at least 2 minutes – after which the valve 

automatically switches the system back to filter state.

Q6: Does the Aite Horizontal Multi-Tank Shallow Sand Filter require special foundation treatment?

A: No. Aite Horizontal Multi-Tank Shallow Sand Filter filtration system is lightweight and requires no special foundation 

treatment – with small footprint and flexible arrangement.

Q7: How does the backwash valve system work in the Aite Horizontal Multi-Tank Shallow Sand Filter?

A: The controller sends the backwash signal to the solenoid valve, which through compressed air signal sends air into the 

pneumatic device. The connecting rod structure controls the four ball valves simultaneously to enter the backwash state.

Q8: What documentation is provided with the Aite Horizontal Multi-Tank Shallow Sand Filter?

A: Each unit includes a factory test report, operating manual, electrical schematics, dimensional drawings, and material 

certificates – ensuring smooth installation and comprehensive operational guidance.
