juice mills

For sugar and juice flocculation, sedimentation, clarification and floatation

11

Soil humectants

It can preserve water and solidify sand for soil and can play a role of humectant on slope grass planting, tree planting, and sand solidification and dust prevention of soil.

12

Textile

Textile Sizing, as a kind of composition for chemical grout, starch textiles

Highly improve the adhesive property, penetrability and desizing performance, enable the textile to have electrostatic prevention performance, reduces the desizing rate, and reduces the starch mixing spots, cloth machine breaking efficiency, and falling objects.

10 years manufacturing experience, with more than 20 technical engineers

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.

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 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 60rpm. Determine the flocs properly at this time and note the sedimentation and clarity of top solution.
