Automatic valveless Gravity Filters

Automatic valveless Gravity Filters

With a keen interest in water filtration IEC has developed its proprietary SEBAC filtration technology. The SEBAC filter is capable of reducing suspended solids in process water.

Benefits:
Automatic Valveless Gravity Filters marries the simplicity of gravity filtration with a purely hydraulic backwashing.
The result is a very simple unit with very high efficiency and low capital and working costs. This innovative filtering technology has the advantage of being able to treat large flows of water with no energy consumption for backwashing operation. In fact no rotating machinery is required and no costs for spare parts, and more importantly no-operator intervention.

This is further enhanced by the fact that no control equipment is required (automatic valves, flow-meter, transmitters).

Features:
• Automatic operation, no valves nor backwash pump required
• Backwashes automatically
• 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

Operation
• 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
