Municipal and industrial waste water treatment plants are designed to produce a clean, safe water discharge within the required limits.
The complexity of the plant will depend on the immediate environmental considerations and the consent limits negotiated with the authorities. New plants built today are becoming more and more sophisticated and decanter centrifuges are extensively used for liquid-solid separation, sludge dewatering, and sludge thickeningapplications. There are basically (2) two decanter centrifuge applications in the municipal and industrial wastewater treatment facilities and wastewater treatment industry:
The first is to feed to the decanter centrifuge liquid slurry (around 1 – 3 % dws.) and thicken it to approximately 8% dws, often prior to feeding the thickened material to a biological digester.
The second is to feed the decanter with similar slurry and dewater the solids to a relatively dry stackable cake of leach free solids prior to transportation or disposal. In the second case the solids can come from the primary clarifier or the secondary clarifier after biological treatment.
