Series Product Development of Cation Flocculant of Starch Graft Acrylamide

 

Technology Subject

     SERIES PRODUCT DEVELOPMENT OF CATION FLOCCULANT OF STARCH GRAFT ACRYLAMIDE

Technology SN

      96005

Technology Details

     The flocculant is a kind of material that greatly reindorces the solid-liquid separation. In the foreign countries they began the research in the 1960s and used the organic and inorganic high polymer flocculant.The starch graft ion flocculant is a kind of new high polymer material with the basic material of the starch, polymerize the acrylamide graft then produce the series products after a course of changes.QAGSAN has all the characters of cation starch, polyacry lamide and cation polyacry lamide, so it can be the substitute of all the above products and has the sterilizaion function.

Technology Principle

     

Application Scope

     The products of the small-scale experiment are widely used in the industrial wastewater, domestic wastewater in paper making, textile, porcelain, oil field, printing and dyeing industries. After the treatment for Liaohe River, COD and BOD in the discharge water meet the discharge standard of the state. The middle experimental product is now carrying out the practical research after the medium experiment.

Technology Index

     Graft polymerization:
     Monomer transfer rate>98%
     Graft rate>140%
     Graft efficiency>95%
     Hydroxymethylation: transfer rate>70%

Economic Feasibility & Market Forecast

     The new high polymer flocculant is used with the inorganic flocculant together. COD and BOD of the treated water can not only meet the national discharge standard but prevent the water quality from being further deteriorated. The treated water utilizing the flocculant can be recirculated and has the function of the corrosion delayer. When treating the industry wastewater, about 2-10 ppm of flocculant is needed according to the water quality and cost of per ton wastewater is about 0.06-0.4 Yuan and 2-3ppm is needed when treating the domestic wastewater, the cost is 0.06-0.1 Yuan. Plus other inorganic dose,the total cost for treating each ton of wastewater is 0.2-0.8 Yuan. If set up a set of flocculant manufacture equipment whose yearly productive is 500 tons, the equipment investment is about 400 thousand Yuan, Starch graft acrylamide polymer Cost of raw material¡Ã1500; Water, power and gas: 200; Management fee:200 Depreciation charge for the equipment:100; Total:16500; Sales price:25000-30000; Solution for the achievement transfer:
     (1) On the basis of the existing small-scale experiment, it can organize the industrial production and allocate with the relevant wastewater treatment equipment and engineering.
     (2) The achievement can technically transfer once for all or absorb shares.
