Chemical and spectroscopic analysis of olive mill waste water during a biological treatment [PDF]

open access: yes, 2007
The treatment of olive mill waste water was studied on the laboratory scale. Physico–chemical analyses showed the final products had a mean pH of 5.4 without neutralisation and 5.7 when lime was added to the process.
