Equivalent Praestol 2500 Nonionic Polyacrylamide For Potassium Chloride Producing

Description:

1. Soluble in water, safe, non-toxic, hydrolytic stable, is not sensitive to the change of pH value, 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 immediately with plenty of water.

2. 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, and have obvious to speed up the solution to clarify, promote filtering, and other effects.

Dissolving 
concentration:

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

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 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.

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.

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 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.
