Table A2.4: Treatment efficacies for industrial contaminants and miscellaneous organic compounds of health significance

Return to the point in the document where this table is located.

Table symbols: * limited removal; ** more than 50% removal; *** more than 80% removal.

Where a < value is noted in the table, this is the minimum concentration (mg/L) that can be achieved by the process, even if the combination of initial concentration and percentage removal indicate that a lower concentration can be achieved.
