Automatic Valveless Gravity Filters (AVG)
An engineered system that meets your needs. Automatic controls save labour and provide a better filtration system without the need for valves, pumps, flow controllers or electricity.
An engineered system that meets your needs. Automatic controls save labour and provide a better filtration system without the need for valves, pumps, flow controllers or electricity. Backwashing on demand or by manual activation.
The control module provides all hydraulic functions of backwash initiation and washing of the filter media.
Technical Specs
Filtration rate: 2.5 L/sec/m2 โ 9m3/hr/m2
Backwash rate: 15 to 7 mm/sec (10 L/sec/m2 average)
Automatic operation, no valves nor backwash pump required
Backwashes automatically, or by manual initiation
The control model provides all hydraulic functions of the filter inlet, backwash initiation and the wash cycle
Automatic backwash when suspended matter removed by the filter bed causes pressure loss
Flow reverses automatically at the end of backwash. During the rinse cycle, the backwash tank refills and the filter returns to service
Raw water flow to the plant is not interrupted
Whenever suspended matter removed by the filter bed causes pressure loss to reach a predetermined level, backwash starts automatically
Flow reverses automatically at end of backwash; during rinse cycle the backwash tank refills and the filter returns to service
Raw water flow to the plant is not interrupted.
