دردشة على الإنترنت2017year6month16day Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations – control for disturbances – in the process feed stream to deliver a clear overflow and thickened underflow.
دردشة على الإنترنتThe thickener plays a crucial role in achieving the desired texture of the product. For e.g., a thickener that imparts a luxurious and velvety feel may be preferred for high-end creams. Whereas, a lightweight and non-greasy texture may be desired for lotions. The chosen thickener should align with the desired texture attributes of the formulation.
دردشة على الإنترنتIt is crucial to predict the outputs of a thickening system, including the underflow concentration (UC) and mud pressure, for optimal control of the process.

دردشة على الإنترنت2023year6month21day A gravity thickener is much like a clarifier in that the sludge/water mixture enters through the center in the influent line. This reduces the hydraulic force of water and sludge that enters the thickener. In the lower portion of the thickener is the sludge rake, which moves sludge to the hopper, where sludge is collected and compacted.
