Cationic Polyacrylamide Flocculant

News / By jolin

Cationic Polyacrylamide Flocculant Cationic polyacrylamide flocculant, cationic flocculant has a strong flocculation and sedimentation effect on suspended particles in the aqueous medium. Cationic polyacrylamide flocculant sedimentation 1. Negatively charged suspended particles lose their dispersion stability through electrical neutralization. 2. Through the "bridging" effect, suspended particles are aggregated into large particles to accelerate sedimentation. The aggregates …

Polyacrylamide for Sand Washing Plant

News / By jolin

Polyacrylamide for Sand Washing Plant Polyacrylamide is used in sand washing plants. The mud water in sand washing plants is a suspended liquid containing a certain amount of fine mud particles in the water. The characteristics of the mud depend on its composition and local geological conditions. Generally, the appearance of the mud is earthy …

What Is the Impact of the Ionicity of Cationic Polyacrylamide?

News / By jolin

What Is the Impact of the Ionicity of Cationic Polyacrylamide? What is the impact of the ionicity of cationic polyacrylamide? The ionicity of cationic polyacrylamide is the charge density of polyacrylamide itself. It is a relative concept. The higher the charge density, the higher the ionicity. The ionicity determines the molecular chain length and price …

Application of Polyacrylamide in Paper Industry

News / By jolin

Application of Polyacrylamide in Paper Industry The application of polyacrylamide in the papermaking industry. As a flocculant, polyacrylamide can promote the accumulation of suspended solids, colloids and other substances in sewage to form flocs for subsequent filtration, sedimentation and other treatment processes. In order to improve the strength of paper and save papermaking raw materials …

Anionic Polyacrylamide

News / By jolin

Anionic Polyacrylamide Anionic polyacrylamide promotes particle flocculation by neutralizing the charges on the surface of suspended particles in water, thereby destabilizing the particles in the water. The destabilized particles adsorb each other under the bridging effect of the active genes of the polymer polymer, and then form larger of clumps. How to use anionic polyacrylamide …

Treatment of the Problem of Viscosity Decrease of Polyacrylamide Solution

News / By jolin

Treatment of the Problem of Viscosity Decrease of Polyacrylamide Solution To deal with the problem of decreased viscosity of polyacrylamide solution, after polyacrylamide is prepared into a solution, if it is not used in time, the viscosity will decrease when it is used again after a period of time. So what is the reason for …

Pay attention to the use of polyacrylamide in sludge dehydration. There are many types of polyacrylamide, so the selection of the type is more important, because it is an important factor affecting the effect, and then it is the problem of the operation process after the selection. Operational Problems of Polyacrylamide Used in Sludge Dewatering 1. Water pressure problem, sometimes due to insufficient water supply pressure, the dissolution funnel of the material feeder cannot send the polyacrylamide agent into the preparation pool, resulting in blockage. The solution is to use a water pump to increase the water pressure. 2. The sludge dehydration polyacrylamide solution is recommended to be prepared and used immediately to prevent it from being left for too long and may affect the treatment effect. 3. When the container is cleaned, it should be cleaned in all aspects, so that the impurities sticking to the wall of the drum can be better cleaned up, and the drum can be given a balanced speed. 4. Regularly adjust the operating frequency of the dehydrator. When the dehydrator vibrates violently, it should be prohibited to feed again immediately, and the next step should be dredged first. 5. The concentration of sewage sludge is relatively high during water purification. At this time, it is best to let the sewage stand for a period of time, and then extract the clean solution above to increase the concentration of sludge for treatment.

Selection Method of Cationic Polyacrylamide

News / By jolin

Selection Method of Cationic Polyacrylamide 1. Sampling sludge samples to be pressed: Select representative sludge samples and take samples before the on-site dosing point. After taking the samples, the experiment should be carried out as soon as possible (the properties of the sludge may change after being left for a period of time). Polyacrylamide samples: …
