Web15 Sep 2009 · In addition, the timescales for effective flocculation under applied shear are much shorter for larger particles at typical thickener feed solid concentrations, measured … Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the separation of … See more The measurable parameters that can be used for thickener control include thickener feed flow rate, feed density, underflow density, overflow clarity, bed level, bed mass, rake … See more Rake torque is the most fundamental instrument and an accurate indicator of when things have already gone really wrong! Under normal circumstances the torque is an indication of the force necessary to drive the … See more Bed mass is utilized to control thickener inventory. Bed mass is generally measured by a pressure transducers mounted at the bottom of the tank … See more Bed level is a frequently installed instrument and can be installed and serviced during normal thickener operation. Instruments measure the height of the interface … See more

WebCoagulation and flocculation are often used in combination. In some cases, the use of a coagulant or flocculant is sufficient to form settleable and floating floccules. The aim of coagulation is to destabilise a colloidal solution, so that polluting matter can bunch together to form floccules. Colloidal or suspended particles have a negative ... WebThickeners are a key unit in many hydrometallurgical processing operations for the separation of solids and liquor. Flocculant is often added to bridge the particles into large, … WebA flocculation performance of co-polymers (Superfloc A-130 and A-100) was compared with coagulants (Al2SO4 18H2O, CaCl2 and FeCl3 6H2O).
