Main application of cationic flocculant (FO4190 4290)
1, as flocculating agent, mainly used in industrial solid-liquid separation process, including settlement, clarification, concentration and sludge dewatering technology, application of the main industries are: urban sewage treatment, paper industry, food processing, petrochemical industry, metallurgical industry, processing industry, dyeing industry and sugar industry and all kinds of industrial wastewater treatment. Used in urban sewage and meat, poultry, food processing wastewater treatment process of sludge precipitation and sludge dewatering by its organic colloid electrical group of sludge negative charge neutralization and excellent polymer bridging coagulation function, prompting colloid particles gathered into large pieces of floc, separated from the slurry. The effect is obvious and the dosage is small.
2, in the paper industry can be used as paper dry strength agent, retention agent, filter agent, can greatly improve the quality of paper, cost saving, improve the production capacity of paper mill. Can directly and inorganic salt ions, fibers and other organic polymers electrostatic bridge effect to enhance the physical strength of the paper, reduce the loss of fiber or filler, speed up water filtration, enhance, help to stay, help to filter, can also be used for white water treatment, at the same time, in the process of deinking can play a significant flocculation effect.
3, fiber mud (asbestos-cement products) can make the forming of asbestos-cement products drainage is improved, so that the strength of asbestos slab is improved; In the insulation board, the combination of additive and fiber can be improved.
4, in mining, coal preparation industry can be used as mine wastewater, coal washing wastewater clarification agent.
5, can be used for dyeing wastewater, leather wastewater, oily wastewater treatment, turbidity removal, decolorization, in order to meet the discharge standard.
6. In the purification of phosphoric acid, it is helpful to the separation of gypsum in the wet phosphoric acid process.
7. Flocculant for water treatment in waterworks with river water sources.
8 flocculant polyacrylamide dissolution method and storage conditions
Polyacrylamide is a water-soluble polymer. In general, granular polyacrylamide can be stored in a dry and cool place for more than two years. After the solution is prepared, its storage time is very limited. Generally speaking, when the solution concentration is 0.1%, the non-anionic polymer solution does not exceed one week; Cationic polymer solution does not exceed one day. The stability of the solution is related to the concentration, the thicker the solution (such as 3%-5%), the longer the storage time. However, 3%-5% of the solution can not be directly treated with sewage, and should be diluted before use. Cationic solutions are stable at PH below 5, but rapidly fail due to hydrolysis at PH above 6. It is more sensitive to iron and calcium and magnesium ions than anionic polymers.
The following factors should be considered in the selection of concentration:
A. It is recommended that the mixture be slightly stronger (e.g. 0.3%) due to the small pot and large daily dosage.
B. When the molecular weight of the polymer is very high, it is recommended to mix it with a little thinner (such as 0.1%).
Calculation of time in different seasons:
1. In summer when the water temperature is high, negative and cationic polymers need to be stirred for about 1 hour, non-ionic polymers need to be stirred for about 2 hours;
2. When the water temperature is low in winter, the negative and cationic polymers need to be stirred for about 1.5 hours, and the non-ionic polymers need to be stirred for about 3 hours;
3. The higher the preparation concentration, the faster the polymer dissolution rate. Uneven or inadequate dissolution will affect the effect of use.
Iron ion is the catalyst for the chemical degradation of all polyacrylamide, so when preparing, transferring and storing polyacrylamide solution, iron ion should be avoided as far as possible. The equipment in contact with the solution is preferably made of unembroidered steel, plastic, fiberglass or carbon steel with a painted surface
