ABSTRACT
A study was conducted for the removal and recovery of chromium from tannery wastewater, using NaOH, MgO, Ca[OH[2]] and Al[2][SO[4]]. 18H[2]O as precipitating agents and comparing their effect on pH, total dissolved solids [TDS], total suspended solids [TSS], sludge volume and chromium removal. MgO and Ca[OH][2] produced least amount of sludge and dewatering of sludge was also easy as compared to Al[2] [SO[4]][3]. 18H[2]O and NaOH. The chromium removal of MgO and Ca[OH[2] was 95% and 96%, respectively
