Crystal Powder Polymer Cationic Polyacrylamide Flocculation For Wastewater Treatment

Basic Specification:

Summery of Polyacrylamide In Different Formula

Advantage of Our Polyacrylamide(PAM)

• Economical to use - lower dosage levels.

• Easily soluble in water; dissolves rapidly.

• Non corrosive of suggested dosage, economical and effective at low levels.

• Can eliminate the use of alum & further ferric salts when used as primary coagulants.

• Reduction in sludge of dewatering process system.

Introduction Of Polyacrylamide(PAM) And Onionic PAM

Introduction:Polyacrylamide is abbreviated as PAM, and is divided into anion (HPAM) cation (CPAM). Non-ionic (NPAM) is a linear polymer, and it is one of the most widely used varieties of water-soluble polymer compounds.

Application in water treatment:The application of PAM in water treatment industry mainly includes raw water treatment, sewage treatment and industrial water treatment. In raw water treatment, PAM is used in combination with activated carbon, which can be used for coagulation and clarification of suspended particles in living water. In wastewater treatment, PAM can be used for sludge dewatering; in industrial water treatment, it is mainly used as a formulation medicament. In raw water treatment, organic flocculant PAM is used instead of inorganic flocculant. Even if the sedimentation tank is not modified, the water purification capacity can be increased by more than 20%. Large and medium-sized cities use PAM as a supplement when water supply is tight or water quality is poor. In wastewater treatment, the use of PAM can increase the rate of reuse of the water reuse cycle.

Application and Dosage

1. This product is used for the treatment of urban domestic sewage and industrial organic wastewater. It is positive in the acidic or salty medium, and it is very effective for flocculation, sedimentation and clarification of the false floating particles with negative charge.

2. Used for sludge dewatering. According to the nature of the sludge, the corresponding grade of this product can be selected to effectively carry out gravity sludge dewatering before the sludge enters the dewatering machine. When the product is dehydrated, it can produce large flocs, non-stick filter cloth, no scattering during pressure filtration, less dosage, high dehydration efficiency, and the moisture content of the mud cake can reach below 80%.

3. Water treatment flocculant for waterworks with surface water as water source. Low dosage, good effect and low cost. Especially in combination with inorganic flocculants, the effect is better.

The dosage range of varies from 0.2 - 3.0 ppm depending upon the type of effluent and application. It is always advised to do a jar test for evaluating the functioning and approximate dosage.

Jar Test

Put sample of effluent in a beaker and add it as designated, agitate for 1 minute at 100-120 rpm and then slowly agitate at 60rpm. Determine the floc properly at this time and note the sedimentation and clarity of top solution.

Precautions

1. The operator should wear protective equipment. After skin contact, wash it with water;

2, the use of the site, if there is a small amount of leakage, can be washed with a large amount of water; such as a large number of leaks, first sweep and then rinse with a large amount of water, emergency can be sprinkled with a large amount of yellow sand to prevent slipping injuries;

3. This series of products should be sealed thanks to the cool and dry place to prevent moisture;

4. The storage period is one year.

Instruction of Use

1. It should be formulated into 0.1-0.3% aqueous solution when using, and it is suitable to use neutral water without salty impurities;

2. Spread the dry powder of the product into the stirred water evenly to ensure that it is well dispersed and swollen in the water (do not add water after adding the powder), so as not to form a "fish eye" or block the dosing pipe, and the operation failure occurs. . The stirring speed is controlled at 100-300 rpm;

3. The solution of this series of products should be ready to use, and should not be placed for more than one day after preparation. When preparing, transferring and storing the product, the equipment in contact with the solution is made of stainless steel, plastic, glass or fiberglass;

4. When this series of products is combined with inorganic coagulant, inorganic coagulant should be added first, when there is obvious scented flower (usually about 30-60 seconds), then add this series of products, can not reverse the order Can not be joined at the same time;

5. The dissolved flocculant is applied by a low-shear conveying such as a screw pump or a diaphragm pump.
