Description:
Application Fields:
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. |
Competitive Advantage:
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 |
Functional Principle
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. |
Application Methods:
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. |
