Description
Spiral Rotary Drum Screens
Spiral Rotary Drum Screens are integrated machines consisting of a drum screen, screw conveyor and compactor. Effluent enters the screen drum and solids are captured. When the drum rotates the solids fall into the spiral conveyor. The spiral feeds the screenings into a compactor where they are compressed and disposed. Screen water continues downstream. The rotating screen drum ensures screen does not blind. Filtration rates of between 1 - 7 mm are available, alongside flow rates of up to 7600 m3/h.
Construction
Housing constructed out of high quality 304 stainless steel to ensure years of trouble free operation. Spiral manufactured out of carbon steel with optional 304 stainless steel construction. Nylon cleaning brushes bolted to spiral. Spiral Rotary Drum Screens can be supplied for direct installation into a channel or as a complete package inside a stainless steel tank with or without the option of a bypass rake screen. Continuous bagging systems are available to receive screenings and abate odour, the screenings can then be sealed without any personal contact. Options for 316 Stainless steel area available.
Operation
Solids within the incoming flow will enter into the drum screen and progressively collect onto the screen mesh and cause it to gradually blind. The upstream water level will rise and at a predetermined level, the drum screen and screw conveyor will activate and rotate, immersing a clean section of the screen into the effluent. During rotation the solids or screenings will become inverted and then fall into the screw conveyor. Spray nozzles and a roller brush fixed to the periphery of the drum screen will clean away any residual solids from the mesh surface. The screenings are conveyed, compacted and dewatered and depending upon the solid properties, a volume reduction of around 40% DS or greater can be achieved prior to disposing the screenings into a skip or holding vessel.
A jet wash facility in the compaction zone will breakdown and remove faecal and other semi-solid or soluble mater and return it to the inlet flow. Additional jets can be installed in the transport zone to meet higher specifications of organic solids removal. Faecal matter washing efficiencies greater than 90% and screenings weight reduction of 50% can be achieved. The compactor and wash system can be omitted to suit requirements such as CSO applications where the screenings are returned to the downstream sewer.
