Application of QUANSEN PAM in food wastewater

Selection of PAM for food wastewater plant

The waste water of food factory contains a lot of organic matter, and the cationic polyacrylamide flocculant is usually used to treat this kind of waste water.If secondary biochemical treatment is performed on site, anion PAM is used. Cationic flocculants are used in sludge dewatering.

The polyacrylamide flocculant PAM selected by food factory needs to consider the molecular weight and ionic degree of polyacrylamide PAM, and then the better model is determined through tests. When using PAM flocculant to treat wastewater in food factory, factors such as origin of sludge, size of flocculant, ionic degree of polyacrylamide PAM and strength of flocculant should be considered. To understand the source, property, composition and solid content of waste water in food plant, we can determine the ion flocculant PAM preliminarily.

According to the requirements of on-site treatment process, it is better to judge whether the flocculation is large or small, because too small flocculation will affect the drainage speed, and too large will make flocculation bind more water and reduce the degree of mud biscuit.Flocculant polyacrylamide with different molecular weight can adjust the size of flocculant.Then, according to the filter press used in the dewatering of sludge in the food plant, PAM, a flocculant with different ionic degrees, is selected in the laboratory for type selection test, and the models with relatively tight and stable flocculation are selected.

In conclusion, the treatment of waste water of food factory needs to pass strict beaker test, and select better model to get better solid-liquid separation effect and better sludge dewatering effect.For the treatment of the waste water of the food factory, suzhou haono has accumulated a lot of experience in the selection and use of polyacrylamide flocculant. According to the specific use requirements of the food factory, flocculant products can be selected with different on-site techniques and equipment. Choose more suitable and cost-effective polyacrylamide flocculant products for the food factory, and find a more suitable solution for the sewage plant.

Advantage of QUANSEN PAM

Flocculant polyacrylamide should be used in the process of sludge dewatering after food wasterwater treatment. As a sludge dewatering agent, medium and high cationic polyacrylamide is recommended.

Solid polyacrylamide generally consumes 3-8 kg per ton of absolute dry mud.The specific dry mud dosage should be determined according to the beaker experiment, on-machine medium experiment or periodic operation test. The mud quality of each factory is different, and the consumption of different sludge, agents, equipment and management level varies greatly.

The treatment agent of cationic polyacrylamide for QUANSEN factory is very effective. QUANSEN PAM Molecular weight is no other factory can match.

method and attention

1. Determine the best model and the best dosage of the product through small tests.

2. The product shall be prepared into an aqueous solution with a concentration of 0.1-0.2% (referring to the solid content), which shall be prepared with water with a PH value of 7 or less, and neutral water without salt is preferred.

3. The dissolved water, will this product evenly into the mixing water, proper heating (< 60 ℃) can accelerate into solution.

4. This product has hygroscopicity and should be sealed in a cool and dry place, the temperature is lower than 35 ℃.

5. Solid products should not be scattered on the ground, so as to avoid slipping after absorbing moisture.

6. When dissolving, the product should be added into the dissolver evenly and slowly, and the solidification should be avoided and mechanical shear that has been over for a long time should be avoided.

It is recommended that the mixer be 60 to 200 RPM, otherwise the polymer will hydrolyze and affect the use effect.

7. PAM aqueous solution should be used and prepared now. When the solution is placed for a long time, its performance will gradually decline depending on the water quality.

8. After adding the aqueous solution of the polyacrylamide to the suspension, the flocculant will be destroyed if stirred violently for a long time.


storage

The original product shall be kept sealed.Storage environments should be a cool, dry and ventilated, at room temperature for 10 ~ 40 ℃.Special precautions should be taken to prevent product absorption.

In accordance with the specified storage conditions, the original packaging products can be stable for at least 12 months.


packing

25kg composite paper bag /750kg pallet OR customer demand.
