Canada Non-Ionic Temperature-Resistant And Salt-Resistant Polyacrylamide for Dyeing Wastewater Treatment

In the neutral detergent process, non-ionic detergents of the ethylene oxide condensate class are added to water at a pH of 6.5 to 7. 5 and a temperature of 135° to 160° F. (40). The process is carried out in a series of four open bowls called "scouring train".

In this study, suitability of xylano-pectinolytic enzymes in pulping of wheat straw has been explored. The suitable biopulping conditions were optimized, with xylanase dose of 400 and pectinase dose of 120 IU/g wheat straw, 1:10 (g/ml) material to liquid ratio, 55 °C temperature, 3 h treatment time, 0.75% Tween 80 and pH 8.5.

Jan 31, 2011 · Besides dyes, dyeing wastewater also contains chemical auxiliaries like salts, heavy metals, dispersing agents, smoothing agents, surfactants (i.e. to minimise aggregation of dyes) etc. which makes dyeing wastewater more complex to treat and raises the need for more than a single treatment step , .

Residual acrylamide monomer occurs in polyacrylamide coagulants used in the treatment of drinking-water. In general, the maximum authorized dose of polymer is 1 mg/l. At a monomer content of 0.05%, this corresponds to a maximum theoretical concentration of 0.5 μg/l of the monomer in water. Practical concentrations may be lower by a factor of 2 ...

Their glass transition temperature is well above room temperature (> 400 K). The only commercially important polyacrylamide is poly(2-propenamide) which is simply called polyacrylamide or PAM [-CH2CH(CONH2)-]. It is a non-ionic, watersoluble, and biocompatible polymer that can be tailored to meet a broad range of applications.
