This feeds the backwash spray-water pipes of the rotating screens.

The wash-water and debris from the screens run in a deck flume and reach the debris collection zone.

The debris filter backwash water flow is rather high compared to that of rotating screens and the water returns under pressure to the condenser outfall side.

Safe operation requires that when the head-loss reaches a preset value, the cleaning cycle is started and carries on for a minimum period of time or until the head-loss has dropped back to clean machine values.

BEAUDREY supplies and installs the necessary control cabinets for its supply. BEAUDREY can meet any customer-imposed standard for instruments, computers and switchgear.

There are two main types of cathodic protection systems BEAUDREY can propose.

As shells and marine life tend to grow in the grouted stoplog guides, BEAUDREY can supply a heavy guide scraper frame which is lowered into the guides. Its blades scrape off the shells and growth which have adhered to the surface. After having used the scraper, gate lowering and sealing capacity are much improved.

By-pass valves are an optional feature for drum screens and all types of travelling band screens (except for the thru-flow type).

The efficiency of a condenser tube-cleaning system is dependent on the quality of the cleaning balls injected to clean the tubes. The sponge balls have a diameter that is slightly larger than the ID of the condenser tubes, allowing them to have constant contact with the tube walls. The balls gently scrub and sweep the tubes as they move through them.
