Research on zeolite modification and its removal of ammonia-nitrogen in source water

High concentration of ammonia-nitrogen in source water is extremely harmful to human health.How to remove ammonia-nitrogen efficiently and at low-cost in tap water has been a tough problem for numerous water plants.In this study,experiments were conducted using source water to investigate the effect of zeolite size,contact time and temperature upon the ammonia-nitrogen removal by zeolite modification with acid,salt and high temperature and the ammonia-nitrogen removal test.The results show that ...
