| Abstract: | Limeferrous sulphateinoculating crystal process for treating waste water containing heavy metal ions is discussed in which the first stage neutralization tank was operated at pH*$8 and Fe/As 15, the second stage oxidation tank at pH 93 and Fe/As 10 and the second stage neutralization tank at pH 11 and with 20%30% of reflux ratio of inoculating crystal The content of heavy metal ions, As, F and suspended solid and pH of treated waste water are all up to national standard |
