Multi-tank shallow sand filter – auto backwash, space-saving.

1. Product Introduction

Aite Multi-Tank Parallel Shallow Sand Filter can be used as a stand-alone filtration system using the supply water pump 

in the existing process, or if used as a bypass filter, it can be equipped with its own pump separately. Multiple processing

 units can also be installed on the common pipe, so that the system can achieve unlimited filtration capacity.

 The backwashing of Aite Multi-Tank Parallel Shallow Sand Filter can be done manually, semi-automatically,

 or fully automatically – started by manual button, PLC, pressure difference, or management system respectively.

 Backwash cycle and backwash time can be adjusted, set to 3 minutes when leaving the factory. This control by DCS 

automatic filter control system can be achieved, and users can also choose a PLC control system to achieve centralized 

or remote communication and other high requirements of control.

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

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

worldwide.

2. Principle of Filtration

Aite Multi-Tank Parallel Shallow Sand Filter operates through a two-stage process:

Filtering State

When the system is in the filtering state, pressurized water flows into the water distribution system from the filter unit

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

matter is intercepted by the filter material. The bottom of the filter has a precision gap collector, and filtered clean 

water is uniformly collected and flows out of the filter.

Backwash State

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

When the pressure difference increases to a certain set value or reaches the set cleaning time, Aite Multi-Tank Parallel 

Shallow Sand Filter automatically switches to the backwash state. Pressurized water enters the filter material layer 

through the water collection device and washes it to make the trapped pollutants fall off and discharge out of the

 filtration system. After the backwash lasts for at least 2 minutes, the valve automatically switches the system to the

 filtered state.
