Flocculant CAS Number 9003-05-8 Sludge Treatment Chemicals Non-ionic polyacrylamide (NPAM)

Description:

1. Non-ionic polyacrylamide (NPAM) is a water-soluble polymer formed from acrylamide (a compound with the molecular formula C3H5NO) subunits special for steelworks wastewater treatment with high performance.
2. Soluble in water, safe, non-toxic, hydrolytic stable, is not sensitive to the change of pH value and is anti-chlorine. Harmless, non-flammable, and non-explosive, it can be stored at room temperature, and it cannot be placed in the sun. It is slightly acidic, when skin contact, wash it immediately with plenty of water.

1

Dissolving

concentration:

Polyacrylamide (polyelectrolyte/flocculant) should be standardly 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. An incomplete mixture of flocculants 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 1HP for a 1-2m3 mixing tank.

4

Application

and Dosage:

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

Package and Storage:

• Packed in Kraft or PE bags with inner plastic bags, with each bag containing 25kgs, or 750kgs net big bag.
• Stored in the original packaging in a cool and dry place, away from sources of heat, flame, and direct sunlight.
