1

Oil field

Oil field profile controlling and water- plugging agent, matched with lignocellulose

and a certain amount of chemical adhesive added. It can be used as oil field profile

controlling and water-plugging agent.

2

Well Drilling

Mud Additives

In oil field, as a kind of mud additives.

To increase the viscosity of water and improve the effectiveness of the water flooding

process.

3

Metallurgical

Mineral Dressing

In floatation and smelting of Zinc, manganese and copper mines, its leachate

and slag can be added into PAM to improve the separation efficiency.

1

Economical to use - lower dosage levels.

2

Easily soluble in water; dissolves rapidly.

3

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

4

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

5

Reduction in sludge of dewatering process system.

6

Faster sedimentation, better flocculation.

7

Non-pollution (no aluminum, chlorine, heavy metal ions etc.).

8

10 years manufacturing experience, with more than 20 technical engineers

1

Flocculation Mechanism:

Adsorbing suspension particles, polymer chains entangle and cross-link each other to form bridging, and make flocculation structure enlarge and thicken, and has the functions of surface adsorption and electric neutralization.

2

Reinforcing Mechanism:

PAM molecule chain and dispersed phase form bridging bond, ion bond and covalent bond to increase combination strength.

1

Dissolving

concentration:

Polyacrylamdie (polyelectrolyte/flocculant) should be standardly be dissolved to 0.1-0.5% concentration.

2

Dissolving

time:

The time required to dissolve the flocculant varies according to the type of flocculant, water quality, temperature and agitation. However, most flocculants generally require around 1 hour of agitation to completely dissolve the powder. Incomplete mixture of flocculant or lumping may inhibit the performance of the flocculant.

3

Agitation

speed:

The ideal revolution of the agitator is between 200-400rpm. A high speed agitator operating without reducing the revolution of a motor is not advised, since it may cut the molecules of the flocculant. An ideal agitator motor should be of 1HP for a 1-2m3 mixing tank.

4

Application

and Dosage:

The dosage range of varies from 1 - 3.0 ppm depending upon the type of effluent and application. Advised to do jar tests for evaluating the functioning and approximate dosage.

5

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 flocs properly at this time and note the sedimentation and clarity of top solution.
