The Higher The Ionicity, The Better The Effectiveness of The Polyacrylamide in Pressing Mud?

January 11, 2024

With the increasing awareness of environmental protection, polyacrylamide, as a chemical widely used in the field of Water Treatment, the effectiveness of its use has attracted much attention. Especially in sludge treatment, the ionicity of polyacrylamide has become a key factor affecting the effectiveness of sludge pressure.
1.The meaning of ionicity of Polyacrylamide
The ionicity of polyacrylamide refers to the number of charges on its molecular chain. Usually, the higher the ionicity, the more charge on the molecular chain of polyacrylamide. This has an important impact on its performance in the water treatment process.

2.The effect of ionicity on the effectiveness of sludge compaction
In the process of sludge treatment, the role of polyacrylamide is mainly used as a Flocculant, so that through flocculation, the suspended particles in the sludge coagulate into large particles, which is easy to settle and filter. After the polyacrylamide with high ionicity is dissolved in water, the charge on its molecular chain can produce an attraction with the charge of the particles in the sludge, thus promoting the aggregation of particles.
However, the higher the ionicity, the better the sludge compaction results. Too high ionicity may lead to excessive agglomeration of sludge particles, forming hard lumps that are difficult to separate, which is not conducive to sludge compaction. In addition, high ionicity polyacrylamide is also easy to lead to scaling and clogging on the surface of the equipment, affecting the normal operation of the equipment.

3.Selection of suitable polyacrylamide ionicity
Therefore, it is quite important to choose the appropriate polyacrylamide ionicity. In practical application, it is necessary to choose the appropriate ionicity according to the characteristics of sludge and the requirements of the treatment equipment. For some specific sludge treatment occasions, it may be necessary to use a specific ionicity of polyacrylamide to achieve better results.
Farmers can choose the right organic fertilizer according to the situation. It is not possible to measure or choose a kind of organic fertilizer simply based on the price. In addition, it is recommended that when growing vegetable crops such as melons and tomatoes, the vegetable farmers should not simply use commodity organic fertilizers, and can invest in farmyard manure and commodity organic fertilizer at a ratio of 1:1, which can prevent commodity organic fertilizers from being effective. Shortcomings. Supplementing beneficial microorganisms is also crucial when changing.
