Annually about 100 systems with automatic sludge removal and about 250 semiautomatic systems are sold. However, this elaborate technology can be utilized for applications like dewatering of the sludge from paint booths, the treatment of waste water generated during the glue operation in wood processing industries, the processing of waste water created in glass grinding operations as well as the cleaning of effluent containing silicon carbide (SiC) that is generated in the production of semi-conductors and wafers. One reason for the successful use of R\u00f6sler centrifuges in these applications is the high throughput of up to 6,000 liters\/hour with the automatic centrifugal filter systems. Of great importance are not only the cleanliness requirements for the different applications but also the physical limits regarding particle size and weight.
\nThe design of the R\u00f6sler centrifuges places great emphasis on ease of maintenance, especially accessibility to the rotary drum with indirect drive. The drum itself comes standard in aluminum; for special applications like for the separation of glass particles or silicon carbide it is made from stainless steel. This prevents a chemical reaction and, thus, corrosion of the drum. The drum has a capacity of up to 30 kg of sludge with the advantage of long time intervals between sludge „peeling“ cycles. With regard to sludge peeling the R\u00f6sler design offers another advantage: In competitive systems the peeling knife is constantly rotating with the drum, and it must be moved to the drum wall for the peeling cycle with a gear motor. In the R\u00f6sler systems the peeling knife is completely independent from the rotary drum. Mounted on a linear guide rail the peeling knife is pneumatically moved to the inner drum wall for the peeling cycle.
\nThe peeling cycle is followed by a rinse step for removal of residual sludge. This prevents an imbalance in the rotary drum during the subsequent cleaning cycle.
\nThe clean liquid phase – separated from the solid phase in the high-speed drum – is picked up by a pickup tube and transported to either a clear water buffer tank or directly to drain. Frequently, the mechanical cleaning effect of the R\u00f6sler centrifuges is supported by the addition of special chemical flocculants which allow the removal of very fine particles from the effluent.
\nIn Germany R\u00f6sler is certified as a waste recycling company and, thus, is authorized to take back the sludge from centrifuge applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
