Beaudrey - Sand-Removal Systems
The BEAUDREY sand-collecting gantry is installed across the settling tank channel. It runs on Rails secured at deck level to the channel’s side walls. It travels forwards and backwards along the sand-settling channel. Travel is either continuous or periodical depending on the plant’s specific needs. A pump is installed on the pipe carried by the gantry, it travels along the bottom and removes the sand which travels up to the gantry level and is discharged in a deck flume for disposal. The pump can be either an electrical submerged sand pump or an air-lift bubble device depending on the relative levels of the pit bottom, the low waters and the deck.
BEAUDREY sand-removal systems are used in conjunction with a long settling basin where the sand carried by the incoming water deposits on the bottom.
The BEAUDREY sand-removal system sucks the sand from the bottom of the basin and returns it for disposal in a deck flume. Plants with very sandy water intakes use such systems.
- The BEAUDREY sand-removal gantry removes large quantities of sand that would otherwise settle in the low-velocity zones of the plant or damage pumps and exchanger tubes by abrasion.
- Simple, easy maintenance.
- Fully automatic.
- Widths up to 10 m are standard. Larger machines are available on special request.
- Settling basin length, depth and width: BEAUDREY can help you optimize the design.
- Gantry: painted carbon steel
- Rails: carbon steel
- Pump: cast iron (for fresh-water applications) or duplex stainless steel (for seawater applications)
- Pipework: steel (for fresh-water applications) or GRP (for seawater applications)
