CHAPTER 3 SLUDGE THICKENING

2012-3-22 · This zone is compaction zone. Sludge blanket is defined as the top of the feed zone. The height of this blanket is the main operational control that the treatment plant operator has over the thickener. By increasing the underflow rate, the operator can lower the blanket, and hence the solids residence timeLiquid–Solid Separation in Gold Processing - ScienceDirect2016-1-1 · The ultra-high-rate thickener is sized mainly on hydraulic loading and would therefore have a smaller diameter (and hence, smaller footprint) than the equivalent high-rate thickener. The size limit of this type of thickener (12-m diameter) may therefore require multiple thickeners to handle the full stream.

Thickening

2015-8-13 · Unlike conventional thickeners, high rate thickeners must use flocculants. The basic design of a high rate thickener is below. High rate thickener feed wells are designed to disperse flocculants thoroughly into the feed end to admit the flocculated slurry into the settling zone of the thickener without destruction of the newly formed floccules.Thickeners - MIP Process Technologies (Pty) LtdHigh Rate Thickeners. Perhaps the most significant design optimisation effort in thickening in the last twenty years has been in developing ways to more effectively use the horizontal cross sectional area of the thickener. The introduction of polymeric flocculants gave an impetus to development of High Rate Thickeners.
