Clog-free self-cleaning mechanism<\/strong><\/h3>\n

The heart of the machine is a cylinder that acts as a filter element. It consists of alternating layers of fixed rings and moving rings with a gap in between. Two screws running through the cylinder transfer and compact the sludge through the cylinder, squeezing out the water.<\/p>\n

An external driveshaft ensures the constant movement of the rings, creates an elegant and sophisticated self-cleaning function. At the same time, the precise guidance of the moving rings prevents their contact with the surface of the screws. This friction-less design greatly extends the lifetime of consumables. All while maintaining the typical screw press benefits such as ultra low energy and rinsing water consumption compared to alternatives.[\/vc_column_text][vc_column_text]<\/p>\n

Applicable for practically all sludge types – also highly fibrous or inorganic<\/strong><\/h3>\n

The two screws rotate into each other, breaking up the solids while transferring and compacting them towards the outlet. This makes the machine close to impossible to block, even with highly fibrous or inorganic sludges that would be fatal for common screw presses and other dewatering machines.[\/vc_column_text][vc_single_image image=\u00bb5141″ img_size=\u00bbfull\u00bb alignment=\u00bbcenter\u00bb][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n

Power-saving operation<\/strong><\/h4>\n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=\u00bb1\/2″][vc_column_text]The screws inside the cylinder of the VOLUTE DUO\u2122 rotate at a very low speed – approximately 2 to 4 rpm – and consume very little energy. It reduces the power consumption in kWh per ton of dry solids by up to 90% in comparison with a centrifugal dewatering machine.[\/vc_column_text][\/vc_column][vc_column width=\u00bb1\/2″][vc_column_text]

VOLUTE\u2122 and VOLUTE DUO\u2122 use the moving rings to create a unique self-cleaning mechanism to keep the filter element clean and \u00abopen\u00bb, whereas competing technologies use large amounts of (pressurized) rinsing water for this purpose. That explains the major savings in rinsing water consumption that VOLUTE\u2122 offers.<\/p>\n

Compared to a belt press and a centrifugal dewatering machine with the same throughput, a VOLUTE\u2122 uses 90 to 95% less rinsing water.<\/p>\n

La vida \u00fatil significativamente prolongada de los consumibles reduce el OPEX<\/h3> \n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=\u00bb1\/2″][vc_column_text]The moving rings are driven by an external driveshaft to prevent contact with the screws, creating a friction-less design. This drastically extends the lifetime of consumable parts, resulting in an even better OPEX than our classic models already have.[\/vc_column_text][\/vc_column][vc_column width=\u00bb1\/2″][vc_single_image image=\u00bb30351″ img_size=\u00bbfull\u00bb][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p> \n

No requiere espesamiento previo<\/strong><\/h3> \n

The machine’s design integrates both thickening and dewatering of the sludge, which allows processing of low-concentration sludges – having a TS of 0.5% or more – in a single machine without any pre-thickening system. This eliminates the costs for construction and operation of thickening and storage systems and reduces odors. On top, it reduces phosporus and nitrogen emmissions back into the waste water treatment plant, by dewatering the sludge when it’s as fresh as possible.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p> \n
