Applications: screen filter with automatic electric flushing

Standard Characteristics:

• Filter element: – Stainless Steel screen AISI 316 mesh, supported by a PVC cylinder.

Optional – multi layered Stainless Steel Screen,

• Available filtration: 10-3000 micron
• Filter housing and connections: Carbon Steel ST37.2
• Pre-treatment: sand blasting up to Sa 2.5 grade
• Exterior & Interior coating: electrostatic oven baked polyester-epoxy powder coating with a thickness of 150-200 micron
• Connections: VIC and Flange
• Maximum recommended working pressure: up to 10 bar (145 psi).
• Minimum operating working pressure during flushing: 1 bar (14.5 psi)
• Equipped with an electronic control system 110V, 220V or 380-440V 3-phase, 0,25 HP

Operation:

The flushing valve opens and pressure in the flushing chamber and the dirt collector is significantly lowered resulting in a suction process via the suction nozzles to the dirt collector and from there through the flushing valve discharge. The electric motor simultaneously rotates the dirt collector and moves it along its axis. The combination of the vertical movement and rotation guarantees that the suction nozzles will cover the entire internal screen surface, efficiently cleaning the screen. The whole process takes 15 seconds. During the whole process water supply is uninterrupted.

Applications: Compact screen filters with automatic back flushing

 Standard Characteristics:

• Filter element: – Stainless Steel screen AISI 316 mesh, supported by a PVC cylinder.

Optional – multi layered Stainless Steel Screen

• Available filtration: from 50 -3000 micron
• Filter housing material of construction: Carbon Steel ST37.2
• Pre-treatment: sand blasting up to Sa 2.5 grade
• Exterior & Interior coating: electrostatic oven baked polyester-epoxy powder coating with a thickness of 150-200 micron
• Connections: VIC, Threaded socket and Flange
• Maximum recommended working pressure: up to 10 bar (145 psi).
• Minimum operating working pressure during flushing: 1.5 bar (21.8 psi)
• Equipped with an electronic control system 110V, 220V or 380-440V 3-phase, 0,25 HP

Operation:

Cleaning of the screen is performed automatically once the pressure loss (ΔP) across the filter has reached the preset value up to 0.5 bar (7psi). The flushing valve opens, pressure is released from the hydraulic piston, and debris laden water is discharged through the flushing valve. The electric motor simultaneously rotates the dirt collector and moves it along its axis. The combination of the vertical movement and rotation guarantees that the suction nozzles will cover the entire internal screen surface, efficiently cleaning the screen. The whole process takes 5seconds. During the whole process water supply is uninterrupted. The flushing valve closes at the end of the cycle, pressure reapplied to the piston, moving the nozzles back to their rest position, and the filter is cleaned. During the whole process water supply is uninterrupted.

Self-cleaning process – “Flushing“

The system continuously supplies treated water during the self-cleaning process. When waste accumulates on the Filtration screen a difference in pressure between the Inlet and outlet is built. This differential pressure triggers the cleaning cycle sequence. During the cleaning cycle the control unit issues a command to open the Flushing valve. Pressure in the Hydraulic flushing chamber and dirt collector significantly drops, resulting in suction of clean water from the exterior side of the filtration screen through the nozzles, located on the dirt collector. The flow through the nozzles picks up the impurities accumulated on the internal side of the filtration screen and delivers them to Flushing valve, via dirt collector and flushing chamber. The electric motor rotates the leading screw, which in turn rotates and advances the dirt collector along the filtration screen. The combination of linear advancing movement and rotation efficiently cleans the entire internal surface of the filtration screen. When the dirt collector reaches the opposite end of the Filtration screen, a Limit switch disk is sensed by the Limit switch. The activated Limit switch signals the control unit to finish the flushing process. The control unit issues a command to close the flushing valve. When the flushing valve closes pressure in chamber rises and reaches the pressure at Inlet. This stops the flow of the water through the dirt collector. The filter is now ready for next cycle, with clean and filtered water flowing through outlet. Each BIG filter contains 2 or more screens in one filter body. The flushing process can be programmed (on request) to work either each screen separately or in pairs.

Filtration degree: from 20-3000 micron  **Hydraulic version available on request.
