DESIGN INFORMATION REPORT: CENTRIFUGES. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/M-86/023 (NTIS PB87107876), 1986.
Description:
In the 1960s, manufacturers began to design centrifuges specifically for wastewater sludge applications. In addition, sludge thickening and dewatering processes were improved with the introduction of polyelectrolytes for chemical sludge conditioning. The report contains a brief description of the major components and operational principles of solid bowl, imperforate basket, and disc-nozzle centrifuges, followed by a discussion of centrifuge application to sludge thickening and dewatering. Common problems experienced at centrifuge installations are identified, including causes of problems, significant cost and plant performance impacts, and appropriate remedial measures.
