Description:???
# # Yixing Bluwat Anionic Polyacrylamide A-6516 grade (APAM) is a water soluble polymer formed from acrylamide (a compound with the molecular formula C3H5NO) subunits.
# ?Anionic Polyacrylamide?has a big range of high molecular weight from 5-25?million, with an anionic charge density ranging from 10-60%.
# It is most often used to increase the viscosity of water (creating a thicker solution) or to encourage flocculation of particles present in water.
# Due to the polar groups on the molecular chain containing a certain amount, it can through the adsorption of solid particles suspended in water, bridging between particles or through the charge and make the particle formation of large flocs condensation. So, it can accelerate the settlement of particles in suspension, have obvious to speed up the solution to clarify, promote filtering and other effects.
# Mainly used for various industrial wastewater flocculation sedimentation, sedimentation and clarification treatment, such as iron and steel plant wastewater, electroplating wastewater, wastewater metallurgy, coal washing wastewater treatment, sludge dewatering. Can also be used to clarify and drinking water purification treatment, and sugar & juice mills.
# Soluble in water, safe, non-toxic, hydrolytic stability, is not sensitive to the change of pH value, anti-chlorine. Harmless, no-flammable and non-explosive, it can be stored at room temperature, it cannot be placed in the sun. It is slightly acidic, when skin contact, wash immediately with plenty of water.

Blufloc A-6516 Grade?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. |

Blufloc A-6516 Grade?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. |
