Application of cationic polyacrylamide (Flopam FL2099 FL2599) in water treatment

 

Cationic polyacrylamide is linear polymer compound, because it has a variety of active groups, and many substances affinity, adsorption hydrogen bond. Mainly flocculation negatively charged colloid, except the turbidity, decoloring, adsorption, adhesion, and other functions, suitable for dyeing, papermaking, food, building, metallurgy, mineral processing, coal, oil field, aquatic products processing and fermentation industries such as waste water treatment of organic colloid content is higher, especially suitable for urban sewage, urban sewage sludge, sludge and other industrial sludge dewatering treatment.

use

 

1, as flocculating agent, mainly used in industrial solid-liquid separation process, including settlement, clarification, concentration and sludge dewatering technology, the application of the main industries are: urban sewage treatment, paper industry, food processing, petrochemical industry, metallurgical industry, processing industry, dyeing industry, sugar industry, and various 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 aid, can greatly improve the quality of finished 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 formed 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, water treatment flocculant for water plant of river water source. Less dosage, good effect, low cost. Especially with inorganic flocculant collocation use effect is better. It will be a highly efficient flocculant for waterworks along the Yangtze river, Yellow River and river basins.

 

Usage and precautions

 

1. When dissolving, the product should be evenly and slowly added into the dissolver with stirring and heating facilities, and large lumps and long and violent mechanical shearing should be avoided.

 

2, through the small test, the product is prepared into 0.1%--0.3% (solid content) concentration of aqueous solution, with no salt neutral water is appropriate.

 

3. Determine the best dosage of the product.

 

4, the configuration and storage of aqueous solution should be carried out in enamel, galvanized or plastic buckets, not in contact with iron products.

 

5, this product has hygroscopic, should be sealed in a cool and dry place, the temperature should be below 35℃.

 

6, solid products should avoid scattered on the ground, in order to prevent the product moisture after slippery.
