Two parallel shallow sand filter – auto backwash, no interruption.

1. Principle of Operation

Aite Two Parallel Automatic Shallow Sand Filter is mainly cleaned through the filter material. When the filter material is

 affected by the interception of excessive mechanical impurities, the backwashing mechanism of the filter is set up to 

backwash the filter material. The reverse inlet water is used to loosen the sand filter layer in the filter – making the intercepts

 adhering to the surface of the packing peel off and be carried away by the recoil water. This is conducive to the removal of 

sediment and suspended matter in the filter layer, and prevents filter material compaction – fully restoring intercepting

 capacity and achieving the purpose of cleaning.

As a professional manufacturer specializing in industrial water filtration equipment, we deliver Aite Two Parallel Automatic 

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

2. Product Features

Aite Two Parallel Automatic Shallow Sand Filter delivers superior performance through the following key features:

2.1 Compact Size & Easy Installation

Aite Two Parallel Automatic Shallow Sand Filter features small size and easy installation – saving space. It can be installed

 outdoors without building construction, saving civil construction costs. With small floor area, indoor and outdoor installation, 

and layered installation options, it offers strong adaptability, compact structure, space saving, and good anti-corrosion 

performance.

2.2 Good Anti-Corrosion Performance & Long Service Life

Aite Two Parallel Automatic Shallow Sand Filter has good anti-corrosion performance and long service life – ensuring 

reliable long-term operation.

2.3 High Filtration Efficiency

Aite Two Parallel Automatic Shallow Sand Filter filters water with good filter effect and fast filter flow rate. Normal filter

 speed can be about 40 m/h, and according to water quality can reach 60 m/h. Filter backwash uses product water without

booster pump or backwash pump. Backwashing time is 2–3 minutes with backwash water less than 3 m³. High filtration 

accuracy with impurity filtration accuracy less than 0.10mm – effluent turbidity can be less than 0.5NTU. The filtration

 system consists of a standard unit sand cylinder, and filtration flow rate can be increased from 30.6 m³/h to 2500 m³/h.

2.4 Automatic Backwashing

Aite Two Parallel Automatic Shallow Sand Filter backwashing is automatically identified and controlled by the intelligent 

control system without manual intervention. Even if suspended matter in the water fluctuates, the equipment automatically 

adapts.

2.5 Uninterrupted Water Supply

When Aite Two Parallel Automatic Shallow Sand Filter is backwashed, the filtration process is carried out 

simultaneously – providing water as usual.

2.6 Unique Water Distribution and Collection

Aite Two Parallel Automatic Shallow Sand Filter uses a unique cloth and water collection device – with unique water 

distribution system and uniform water collector making water flow in the whole filtration process layered flow.

 The filter sand bed plane is always smooth during filtration, ensuring stable water quality.

2.7 High-Quality Filter Media

Aite Two Parallel Automatic Shallow Sand Filter uses refined quartz sand or garnet as filter medium, selectable according 

to water quality – with filter particle size of 0.16mm homogeneous filter material.

2.8 Low Long-Term Operation Cost

Aite Two Parallel Automatic Shallow Sand Filter saves electricity, water, and maintenance costs. Power saving: unique 

automatic backwashing valve allows sand filter tanks to backwash one by one under normal system operation – no

 backwashing water pump required. The lift of the filter pump required is 6–7m lower than other sand filtration equipment.

2.9 Water Saving

Aite Two Parallel Automatic Shallow Sand Filter saves water due to unique hydrator and water collector with unified 

specifications tank – backwashing does not require compressed air for effective backwashing. Backwash water used is

 filtered clean water, so consumption is small. Single tank backwashing water is only 1 m³/min with backwashing time 

of 2–3 minutes.

2.10 Low Maintenance Cost

Aite Two Parallel Automatic Shallow Sand Filter saves maintenance costs – the whole system has no mechanical or electric 

valve, relying only on the unique multi-function valve to control the backwash system. The unique multi-function valve 

has no wear, long life, no damage record in 10 years, and low management costs.
