The Nonionic Polyacrylamide is a kind of water-soluble high molecular polymer or called as the polyelectrolyte. Because the nonionic Polyacrylamide’s molecular chain contains a certain number of different polar groups, the nonionic Polyacrylamide could absorb the suspending solid particles in the water, and can help the suspending particles to form the mass floccules by the bridges between the particles or by the charge neutralizing. As a result, the nonionic Polyacrylamide can facilitate the flocculating process of the suspending particles in the water, with the remarkable effects in the solution clarification and in the filtration promotion. The nonionic Polyacrylamide is mainly used for the flocculation and the sedimentation of different industrial waste water, and the treatment of water clarification. The practical application covers the waste water treatment of the paper making and the pulp, the waste water of the mineral processing and the metal smelting processing, the waste water of the steel plant and stone plant etc. 

The NonionicPolyacrylamide for The Beverage Factory

After analyzing the waste water from the beverage factory, it figures out that this type of waste water from the beverage factory is of acidic characteristics, since it contains plenty of the pulp, the protein and the phenolic compound etc.

The natural setting or the direct discharging of such waste water will result in the water deterioration and the odour, therefore, the Nonionic Polyacrylamide is the best choice to be added in the treatment of such type of waste water working as the flocculating agent.

The Nonionic Polyacrylamide can efficiently remove all sorts of organic compounds from the acidic waste water from the beverage factory, it can help to form the floccule quicker and deposit it naturally. The upper clarified water could be released, the sludge in the bottom of the sedimentation basin could be dewatered by using the cationic Polyacrylamide, the mud cake could be used as the feed additives or the fertilizer additives etc.

The Nonionnic Polyacrylamide for the Acidic Waste Water

The Acidic waste water is a type of waste water which contains some acidic material, such as the sulphuric acid, the nitric acid, the hydrochloric acid, the phosphoric acid and the organic acid etc. The acidic waste water is harmful to the aquatic life or organism, and the acidic waste water also can corrode the water supply system and the water resource facilities.

The Nonionic Polyacrylamide could be used as the efficient flocculant in the treatment of such type of acidic waste water, which a much better effect than other Anionic Polyacrylamide flocculant.

The Nonionic Polyacrylamide for the Paper Making Factory

Nowadays, along with the development of the paper making industry, the water system closure is strongly required in the paper making industry, in order to prevent the water being polluted. Therefore, the most economic way is to use the high efficient paper filter aid. After the comparing, the experimenting and the analyzing, it figures out that the Nonionic Polyacrylamide has the best paper filtering effect among all other different water treatment chemicals available.

The Nonionic Polyacrylamide, working as the dry strength agent, the filtering agent and the retention aid in the paper making industry, can greatly improve the quality of the paper product, can greatly reduce the production cost and can greatly promote the production capacity. The Nonionic Polyacrylamide can work directly with the Inorganic salt ions, the fibers and the other organic high polymers by electrostatic bridges to achieve the effect of improving the physical strength of the paper products. As the retention aid and the filter agent, the Nonionic Polyacrylamide can remarkably improve the retention rate of the fine fibers, the fillers and the adhesives, it can promote the paper filtering process in the forming section, and at the same time, the Nonionic Polyacrylamide can reduce the pollution from the white water in the paper making process, the Nonionic Polyacrylamide can keep the system clean which guarantees the normal running and operation of the paper making machines. All of the above mentioned features are the best effects from the introduction of the Nonionic Polyacrylamide in the paper making industry.

The Application Principles of the Nonionic Polyacrylamide Used as the Retention Aid in Paper Making

1. The Nonionic Polyacrylamide is of solid powder shape, therefore, it is required to be dissolved before the practical use. The dissolving Nonionic Polyacrylamide solution has much better effect in practical application

2. It is required to use the clean water to dissolve the Nonionic Polyacrylamide, pure water supply is better. DO NOT use the waste water or unclean water. The reason is that the normal water supply is suitable to make up polymer solution, while, the water of strong acid, alkali condition or high salinity is not suitable to make up such polymer solution.

3. A normal water temperature is required. It will be very slow to dissolve the Nonionic Polyacrylamide if the water temperature is lower than 5 degree. The higher of the water temperature, the faster of the dissolving time of the Nonionic Polyacrylamide. However, if the water temperature is higher than 40 degree, the higher temperature can accelerate the degradation of the Nonionic Polyacrylamide, which will influence the application effect a lot.

4. The concentration of the Nonionic Polyacrylamide solution. For the paper making industry, the best concentration of the Nonionic Polyacrylamide solution is around 0.3%, that is to say, it is suitable to add around 3 grams of the Nonionic Polyacrylamide into one metric ton of the waste water. 

5. The practical and actual concentration of the Nonionic Polyacrylamide solution is required to be adjustable according to practical turbidity concentration of the waste water which is planed to be treated, the actual value is not fixed and could be tailored accordingly.

6. The Nonionic Polyacrylamide solution should be made up instantly in the suitable volume according to the practical needs. Too much Nonionic Polyacrylamide solution will cause the unnecessary waste of the solution and the invalidity due to long time storage of the Nonionic Polyacrylamide solution.

7. DO NOT use steel container or case for the Nonionic Polyacrylamide solution. The direct contact of the steel to the Nonionic Polyacrylamide solution may result in the invalidity of the Nonionic Polyacrylamide solution.
