High-powered cleaning for screens

The cleaning of screens such as those used in Combined Sewer Overflow (CSO) systems requires a robust and vigorous washing jet.  The ScreenBlaster, along with the StormBlaster™ rotary jet head, was designed to clean tanks in the marine industry and has since been re-engineered to meet the specific needs of the water and sewage industry.

The system is entirely fluid-powered. Wash water is pumped through the cleaning head at between 8 and 10 bar pressure. This drives a turbine when rotates the cleaning head in two orientations. The wash fluid then passes through 8 cleaning jet nozzles. The result of this is that 8 powerful jets of water are indexed around the target surface such that they are brought to bear on the entire surface of the screen over a set cleaning cycle time. This mimics the effect of someone manually cleaning the surfaces with a high-pressure hose.

Normally, tank cleaning heads of this nature will bring their cleaning jets to work a complete 360° clean. The 8 Nozzle design of Screen Blaster, however, allows for the cleaning pattern to be restricted to as small as 90°. What this means is that the powerful cleaning jets will impact each part of the surface below with a 90° (or more) cone. Click on the data sheet icon for more product details.
