Research and application of flocculant in production of WPA

For higher sedimentation rate of impurities,lower solid fraction in the concentrated wet process phosphoric acid and heavier productive load,the experiment in lab and industrial facilities for the effects of flocculant on the sedimentation rate of impurities in concentrated phosphoric acid are studied.The results show that the positive effect of flocculant on sedimentation is confirmed and the adequate dosage is determined.
