Influence, of lime concentration on boron removal from ,wastewater, (T = 90° C). The difference observed between lime concentrations of 45 and 50 g L −1 was a surprising result. The reason may be that the calculated value of 45 g L −1 , which corresponds conventionally to an excess of 5%, is not exact, given that the precipitated form of calcium borate is not clearly identified.
