JH Nonionic Polyacrylamide Industrial Organic Wastewater Treatment

         Nonionic polyacrylamide

 

This product is composed of non-ionic monomer and the proportion of acrylamide in different copolymerization and become, is a kind of water-soluble polymer. Can carry on the adsorption of colloid or suspended particles in water, electricity and the Netherlands, such as Bridges, parcels, condensed into a thick floccules, improve and accelerate the solid - liquid separation process, including settlement, clarification, concentration and sewage, etc.

3. Using range

1, this product is used in the processing of urban sewage and industrial organic wastewater, in acid or salt medium into electropositive, in vain with negatively charged particles sewage flocculation precipitation, extremely effective for clarification.
2, used in sludge dewatering: according to the nature of the sludge can choose corresponding grades of this product, can effectively before enter the sludge dewatering machine for gravity sludge dewatering.
When using the product dehydration can produce big floccules, non-stick filter cloth, at the time of pressure filtration diaspora, less dosage, high dewatering efficiency, mud cake moisture content can be up to 80%.
3, used for surface water as water source of water plant of flocculant in water treatment. Less dosage, good effect and low cost. Especially with inorganic flocculant compound with use effect is better.
4, urban sewage and sludge dewatering, generally using cationic molecular weight 8 million - 12 million, 30 to 60 degree of ion products. Plus the amount of 1 ‰ to 3 ‰
5, papermaking wastewater, sludge dewatering, generally using cationic molecular weight 10 million - 12 million, 20 to 40 degree of ion.
6, in the role of pharmaceutical wastewater, sludge dewatering, generally using cationic molecular weight 1200-15 million, 50 to 60 degree of ion products.
More than 7, role in air flotation, use 10-20 ion products.
8, food factory wastewater, organic wastewater treatment, high ion degree required.
9, slaughter wastewater treatment, waste water after fermentation, use 40 more ions, desliming 12 million molecular weight of the product.
10 and other areas, such as chemical waste water, part of fluorite ore pulp, acidic coal washing wastewater, leather wastewater, waste water, such as coal chemical enterprises are using cationic polyacrylamide.

 

4.  Method of use

1, when using general should match into 0.1-0.3% aqueous solution, to use neutral excluding salt sundry water advisable;
This product is 2, dry powder slowly stir evenly into the water, in order to make sure its good dispersion in water, swelling, avoid by all means is to add water after dry powder), not form a "fish eye" or dosing pipe blockage, operating the fault. Stirring speed control in 100-300 RPM;
3, match with a solution of the series of products shall, after preparation place not more than a day, in the preparation, transfer, storage products, contact with the solution of equipment made of stainless steel, plastic, glass or glass fiber reinforced plastic;
4, the series of products when used with inorganic flocculant compound, should first join the inorganic coagulants, with apparent when alum flowers (general interval of time for 30 to 60 seconds), then add the series of products, can't reverse the order; Do not join together at the same time;
5, dissolving good flocculant application of screw pump, diaphragm pump such as low shear transfer.

 

5.  Matters needing attention

1, the operators should wear protective equipment, after contact with the skin, washed with water;
2, use the site, if you have a small amount of leakage, can use a lot of water is rinsed clean; Such as a large number of leaks, first shovel and Saul again with plenty of water is rinsed clean, emergency can be sprinkled on a large number of yellow sand, first to prevent slip and fall injury;
3, the series of products should be sealed thanks to a cool, dry place, in order to prevent be affected with damp be affected with damp;
4, storage life is one year.
