[waters]

Working on proposal for sewage treatment for
a chemical factory,characteristics as follow,

Monitored parameters,average value(discharge requirements):
Flow rate: 100m3/d
PH: 4.3 (6-9)
COD5 :17650mg/l (<100mg/l)
Other oganic compounds like bezene,dimethyl bezene,chloro
bezene,methyl bezene resin, range 30-250 mg/l.

Cl-: 26800mg/l (<350mg/l)
BOD5: 4900mg/l (<30mg/l)
oil and grease: 1370mg/l (<10mg/l)
TSS:3600mg/l (<70mg/l)

Like to know if somebody can help to provide some Economic way to remove Cl-.

Thank you!

at that flow rate invetigate membrane separation, e.g., reverse osmosis, ultrafiltration.
