Flocculant Dilution System in Thickener Feed well

In order to maximise the benefits obtained from flocculating agents when used as settling aids in high rate and conventional thickeners it is often necessary to dilute the thickener feed prior to flocculant addition In some cases no flocculation at all is possible unless dilution water is used The most common method of diluting thickener feed has been to recirculate some of the thickener

The High Rate Thickener Solid Liquid Separation

The High Rate thickeners became popular in the mid 1980 s and are relatively newcomers to the sedimentation line of equipment As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high rate machines Furthermore they are normally positioned far away from

Thickener Operation Zeroday Enterprises

Flocculant Dosage Thickening Filtering CCD Water

Deep level gold ores typically require 5 to 15 g t flocculant and almost always a commonly generic type flocculant If the flocculant dilution is correct and the feed density not too high then ask you flocculant supplier to do some settling tests they normally do it for free Kind regards

Flocculant Addition CEC Mining Systems

Flocculants are polymers that promote flocculation by formation of bridges between themselves and solid particles promoting suspended particle to aggregate As suspended particles are flocculated into larger ones they are settled in devices like thickeners and removed with the underflow

Instrumentation and Control of Sedimentation Equipment

Instrumentation and Control of Sedimentation Equipment Abstract Some of the process variables that are commonly monitored on a thickener are torque rake height bed level bed pressure feed rate and density underflow rate and density settling rate and overflow turbidity Many of these are easily measured while some can be difficult

Thickener Operation and Flocculant Application

Laboratory testing with a high rate thickener has shown the importance of feed solids control to thickener and flocculant performance Table 4 In the preoxidation as well as CCD thickeners testing has demonstrated that an optimum feed solids level can be attained which will maximize thickener performance while minimizing flocculant consumption

Thickener Operating pH and Lime for Flocculation

Flocculants are categorized as anionic nonionic or cationic and therefore affected by pulp pH Basic thickener operation will have you understand the simple electrics of water For lack of proper testing you will need to buy a floc that fits your chemistry or modify it using lime

Difference Between Clarifier and Thickener

The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same Fundamentally thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids Thickeners are used to concentrate solids while clarifiers are used to purify liquids
