SKE - Model SC, ST, SCC & SCT - Spiral Fine Screens
SKE Spiraline fine screens are designed for the removal and compaction of solids from effluent flows. Spiraline screens can be supplied either for direct installation into a channel or as a complete package inside a stainless-steel tank with the option of a bypass rake screen. The flow passes through a screen which captures solids and debris. The spiral elevates the screenings to the discharge height where they are compacted and discharged.
Housing and liners are constructed out of high quality AISI 304 stainless steel to ensure years of trouble free operation. Spiral manufactured out of carbon steel with optional AISI 304 stainless steel construction. Nylon cleaning brushes bolted to the spiral clean the screen. There are no intermediate bearings, so no blockages and no bearings in contact with the liquor. Optional extras include full construction out of AISI 316 stainless steel and jet wash systems. Continuous bagging systems are available to receive screenings and abate odour so that the screenings can then be sealed without any personal contact.
SPIRALINE screens are integrated machines consisting of a screen, a shaft-less spiral and a compaction unit. During operation, solids within the incoming flow will progressively collect onto the screen mesh and cause it to gradually blind. The upstream water level will rise and at a predetermined level, the spiral will be activated. Brushes fixed to the periphery at the lower section of the spiral will then clean the screen mesh and convey the solids up to the pressing zone. The solids or screenings are compacted and dewatered and depending upon the solid properties, a volume reduction of around 40% DS or greater can be achieved prior to discharging the screenings into a skip or wheelie bin.
A jet wash facility will break down and remove faecal and other semi solid or soluble matter and return it to the inlet flow. Additional jets can be installed to the wash system to meet a higher specification of organic removal from the solids. Faecal matter reduction efficiencies to be achieved can be greater than 90%.
