Optimization and improvement to improve quality of WPA
In response to the problems of deep acid colour caused by changes in the quality of raw material phosphate rock,potassium and sodium ion enrichment caused by the increase of purified WPA production capacity,and high production costs,the production of WPA is optimized.By adding flocculants to the filtration system,modifying the mixing facilities of the aging tank,increasing the acid supply level,using the clarification tank and aging tank in series,and adding facilities for removing sludge and sodium fluorosilicate and potassium fluorosilicate,good results have been achieved.
