Anionic Polyacrylamide The Nature Of Matter
Nov 02, 2017

When using polyacrylamide to treat various industrial wastewater, the removal rate of impurities in water is an important index, and it is an important factor to judge the result of treatment. Anionic Polyacrylamide Today's little series for everyone to explain: anionic polyacrylamide treatment of sewage removal rate and sedimentation rate of the relationship.

After the dissolution of anionic polyacrylamide in the process of use, the first is that the precipitation of the chemical reaction is not soluble in the reactant in the solution of the matter, that is, under the action of gravity can be quickly settled, the sewage of suspended substances in the sewage treatment of one of the important technology, technical personnel found: according to the nature of suspended substances, precipitation can be Divided into natural Chen Ding, flocculation precipitation, regional precipitation, Anionic Polyacrylamide and so on, the use of anionic polyacrylamide products for flocculation settlement can be clearly seen in the clear water between the clear mud separation interface!

Anionic polyacrylamide Products in the Flocculation settlement, the suspension of water and colloidal particles in the product of the interaction of molecular forces, the formation of a floc in the sedimentation process of anionic polyacrylamide products produced by the Floc will collide with each other, this time the quality and size of the floc is also changing, the rate of settlement is also increasing, Anionic Polyacrylamide Therefore, the removal rate of suspended matter depends not only on the settling rate of amide, but also on the precipitation depth. Gold and silver crushing and sieving the mineral using grinding machine to add water, Anionic Polyacrylamide lime further grinding, in the next thickener in the settlement, this stage using anionic polyacrylamide, promote the rapid settlement of solids, the substrate through a series of filter tanks to filter. The anionic polyacrylamide Flocculant added in the thickener before filtration.

Lead and zinc in the separation process of zinc sulfide: the mineral is oxidized to zinc oxide by calcination. The oxides are then leached with sulfuric acid. The ph is about 5 of the neutral filtrate and the ph 2.5 of the acid filtrate can make all the concentrate dissolved in sulfuric acid. Anionic Polyacrylamide Some concentrator add a hot filtration thickening process to further improve the recovery rate. The reverse reflux sedimentation system is usually used for neutral concentrated overflow purification. In the lead-zinc filtration process, the use of anionic polyacrylamide Flocculant promotes rapid deposition of minerals and clarification of filtrate, Anionic Polyacrylamide enhances process productivity and reduces mineral loss.

The ore slurry or tailings from the flotation pool will enter the concentration tank for further settling. A flocculant is added to facilitate rapid settlement and to generate a clarification overflow. Clarification of overflow will be used as recycled water. Anionic Polyacrylamide The remaining concentrated tailings will be centrifugal dewatering, and the anionic polyacrylamide Flocculant will be added as a centrifugal additive.
