Blufloc A-3515?Anionic Polyacrylamide Medium Molecular Weight?Polymer , CAS No. 9003-05-8

A-3515?Grade

?

Blufloc A-3515 Description:???
# # Anionic Polyacrylamide A-3515 grade?(APAM) can be used widely for Water treatment, oil drilling, Soil Stabilization and Cement making.
# It 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 05-25?million, with an anionic charge density ranging from 10-60%.
# Our A-3515 grade has medium molecular weight, and medium charge degree.
# It is most often used to increase the viscosity of water (creating a thicker solution) or to encourage flocculation of particles present in water.
# 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.

Application and Dosage:

The dosage range of varies from 0.2 - 3.0 ppm depending upon the type of effluent and application. Advised to do jar tests 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.?

Procedure and precautions upon dispersion and dissolving flocculants:
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.?

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.?

Dissolving concentration:?Flocculants should be standardly be dissolved to 0.1-0.5% concentration. It is also effective to start dissolving at a slightly higher concentration, and then dilute the flocculant mixture immediately before use.?

Handling measures and precautions:
Proper human safety products such as Splash goggles, lab coat, vapor respirator, gloves and boots should be worn while handling and applying chemicals. Splashes on skin should be washed off with water immediately. In case of splashing into the eyes, flush it with fresh water and obtain medical attention. Should not be injected. Please refer MSDS for more details.?
