Understanding Polymer for Thickening and Dewatering

Polymer is used as a flocculant for solids separation processes The aggregation of particles into larger and more removable forms by applying coagulants or flocculants is necessary for efficient separation by clarification, decanting, sedimentation, filtration, thickening, and dewatering processes The terms coagulant and flocculant are oftenAbstract The article presents a casestudy of thickening and dewatering of tailings slimes from Zhezkazgan Concentrating Plant using UltraflocTester machine and different Kemira’s Superfloc series flocculants From among the test flocculants containing various polar groups, the aniontype A150 flocculant has demonstrated the highest efficiency towards tailings slimes Relatively denseStimulation of Thickening and Dewatering of Tailings Slime

How Do You Make A Flocculant Solution 2

How do you dilute a flocculant? Immediately downstream from the flocculant metering pumps, the flocculant must be diluted with fresh water to a final concentration of 005% w/w, ie, for every litre of 05% flocculant solution, 10 litres of water are required to dilute it to a 005% flocculant solutionThe unique design of the Tubox will efficiently and effectively mix the sludge and flocculant solution together, to form a unified floc, for the dewatering press to process The main feature of the device is the highspeed mixing blade which creates a collision effect, allowing the forming of a larger unified and stable flocTubox and Swingmill Dewatering Machine | Sludge
