Polyacrylamide Keep It Steady
Oct 18, 2017

1, sludge is the inevitable outcome of urban sewage treatment, first of all we should understand the source of sludge, nature, composition and solid content. Polyacrylamide According to the sludge contains the main components of different sludge can be divided into organic sludge and inorganic sludge. In general, cationic polyacrylamide for the treatment of organic sludge, anionic polyacrylamide for inorganic sludge, alkaline is not strong when the cationic polyacrylamide should not be used, and acidity should not be used when the anionic polyacrylamide, Polyacrylamide solid content When the sludge is usually high, the amount of polyacrylamide is also large.

2, the size of the floc: floc too small will affect the speed of drainage, floc too will make the flocs to bind more water and reduce the mud cake dryness. The size of the floc can be adjusted by selecting the molecular weight of the polyacrylamide.

3, polyacrylamide ion degree: for the dewatered sludge, Polyacrylamide can be used to different degrees of flocculant by doing a small test for screening, select the best suitable polyacrylamide, so that you can get the best flocculant effect, But also make the least amount of drugs, cost savings.

4, floc strength: flocs in the shear under the action should remain stable without breaking. Increasing the molecular weight of polyacrylamide or selecting the appropriate molecular structure can improve the stability of floc.

5, polyacrylamide and sludge mixture: polyacrylamide in the dehydration of a certain location and the sludge must be fully reacted, the role. To this end, the viscosity of polyacrylamide solution must be appropriate, in the existing equipment conditions can be fully mixed with the sludge, the two mixed even if it is a key factor in success. The viscosity of polyacrylamide solution is related to its molecular weight and formulation concentration.

6, polyacrylamide dissolved: dissolved in order to play a full play flocculation. Sometimes need to speed up the dissolution rate, then consider increasing the concentration of polyacrylamide solution.

Many of the goods on the market have been specially treated, solid content is only about 50%, so the unit price can be very low, and the appearance can not see what changes, the most important thing is: low content of polyacrylamide great shortcomings that is flocculation Exceptionally poor, even if the amount can not change the amount of flocculation, which is the reality of a very wide range of scenes.

Perhaps the company's users have always thought that all the polyacrylamide flocculant are so, and even the treatment is extremely unstable, Polyacrylamide and sometimes meet the standard and exceeded. The company also often suffer losses, but only by investigating the solid particles also do not care, to completely distinguish between the need to do the dissolution of the test: take the same quality solid dubbed flat concentration of liquid, the modulation as much as possible to stir and mix, with the moment of solid Substantially completely dissolved, high molecular weight solution concentration and viscosity were significantly higher than low molecular weight products. High purity of goods generally transparent is very high, defective commodity transparency is low, often with a certain degree of white.
