CHAPTER 3 SLUDGE THICKENING Marmara 220;niversitesi

The gas formed will cause the flotation of the solids in the thickener. Chemicals like chlorine (CI 2) need to be added to inhibit the biological activity. A well operated thickener will have a solids recovery of about 95% [3]. Design of Thickeners The thickening process takes place in a settling tank with long enough solids retention time.

Dewatering of Copper Flotation Tailings Effect of Feed

Jul 19, 20180183;32;Aqueous slurries dewatering using gravity driven thickeners is an essential unit operation in mineral processing. Thickener feed dilution is often used for enhanced flocculation and sediment compressibility. This work investigated the effect of feed dilution on thickener performance for copper flotation tailings.

Conventional Thickeners solidliquid separation

Thickener tanks may be constructed either from steel or concrete and may reach diameters of 120 meters and in earthen basins up to 180 meters. Most of the chemical process industries prefer the steel tanks construction since they may be elevated above ground level, allow inspection of the tank's floor for leakages and bring the underflow slurry pumps nearer to the outlet of the discharge cone.

How to Operate a Thickener Mineral Processing amp; Metallurgy

Running a thickener properly isnt as easy as it looks. True enough, a thickener doesnt make a racket like a ball mill, or spew out froth like a flotation machine, or bounce up and down like a jig, but down inside that big tank there is a lot going on just the same.

FROTH COLLAPSE DE AERATION METHOD FOR FLOTATION CONCENTRATES

The entrainment of finely divided air in thickener feeds can cause significant problems in a thickener's operation, especially in mineral processing plants. This is particularly the case with thickening of flotation concentrates, in which air bubbles are strongly attached to the mineral particles.

Beginners Guide to Thickeners Outotec

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 the solids and liquid.

Removal of Froth from Thickener Thickening, Filtering

An audit of the thickener feed flow will often show points at which the slurry is falling or bends in pipes where air entrainment can occur. A well designed deaeration tank will work if there is room. Thickeners do make surprisingly good flotation cells. Feed pipe modifications are available also.

Sludge Thickening an overview ScienceDirect Topics

A flotation thickener, shown in Figure 9 5, operates by forcing air under pressure to dissolve in the return flow and releasing the pressure as the return is mixed with the feed. As the air comes out of the solution, tiny bubbles attach themselves to the solids and carry them upward, to be scraped off.

Sludge Thickening Concentration Wastewater Treatment

The flotation process in sludge thickening is in principle similar to the flotation for pretreatment of wastewater. In the flotation process, air is injected into the sludge tank from the bottom under pressure and a large amount of air bubbles disperse into the sludge, attach themselves to the sludge solids and float them to the surface of the
