Multi-element auto backwashing filter – V-shaped gap.

1. Working Principle

Aite Multi-Element Automatic Backwashing Filter performs element filtration and backwashing within the filter. 

The original (sewage) water flows from the inside of the filter element to the outside for filtration. Suspended impurities

 in the water are intercepted by the V-end gap holes in the filter element and float around the gap plane. Filtered water flows 

out from the gaps in the filter element.

When the filter holes are blocked by a large number of suspended substances, the pressure difference between filter inlet 

and outlet increases, and backwashing starts. During backwashing, the internal cavity of the filter element is connected to

 the atmosphere through the pressure relief valve (gauge pressure is 0). Filtered water outside the filter element enters as

 backwash water – rapidly washing from outside to inside under the action of large pressure difference. Because the gap

is V-shaped, when backwash water enters from outside to inside, the flow rate greatly increases, forming a great scouring 

and cleaning effect on the gap.

This V-shaped outward-facing high-quality filter element of Aite Multi-Element Automatic Backwashing Filter has excellent

 fluid characteristics – ensuring every automatic cleaning is successful and guaranteeing long-term stable operation.

 Extensive application practice has proved that if the filter element does not have the above characteristics, it will lead to

 filtration and backwashing failure.

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

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

2. Product Characteristics

Aite Multi-Element Automatic Backwashing Filter delivers superior performance through the following key characteristics:

2.1 Synchronized Backwash Pressure Relief and Sewage Discharge

The backwash pressure relief sewage discharge port (DN3) of Aite Multi-Element Automatic Backwashing Filter is controlled

 by an electric valve and acts synchronously with the backwash motor. When the backwash motor starts, the backwash 

electric valve opens, and sewage discharge begins. When the backwash motor stops at the end of backwash, the backwash 

ends and the electric valve closes simultaneously – completing the blowdown.

2.2 Manual Sewage Discharge Outlet

The sewage discharge outlet (DN4) of Aite Multi-Element Automatic Backwashing Filter is controlled by a manual valve. 

The manual blowdown valve should be opened regularly or during cleaning to discharge dirt precipitated to the bottom of 

the main engine.

2.3 Pressure Balancing and Air Release Valve

The pressure balancing valve and air release valve of Aite Multi-Element Automatic Backwashing Filter will open to exhaust

 gas at the beginning of the first work and will be closed during normal work.

2.4 Installation Precautions

During installation of Aite Multi-Element Automatic Backwashing Filter, special attention should be paid to the inlet and 

outlet direction, and no dirt with large particle size should enter the main engine. See the instructions for details.

2.5 V-Shaped Gap Filter Element

Aite Multi-Element Automatic Backwashing Filter features a V-shaped outward-facing high-quality filter element with 

excellent fluid characteristics – ensuring successful automatic cleaning and long-term stable operation.

2.6 Reliable Filtration and Backwashing

Aite Multi-Element Automatic Backwashing Filter ensures reliable filtration and backwashing performance – preventing the

 failure that occurs when filter elements lack the proper V-shaped gap characteristics.

Aite Multi-Element Automatic Backwashing Filter offers reliable filtration at competitive pricing – making it an ideal choice 

for industrial water treatment applications.
