Phosphate and nitrogen removal by iron produced in electrocoagulation reactor. Inan, H. & Alaydin, E. DESALINATION AND WATER TREATMENT, 52(7-9):1396-1403, 2014. abstract bibtex In this study, concentrated iron solution generated by
electrocoagulation (EC) process was used for the removal of nutrients
from human urine (yellow water). Yellow water was prepared synthetically
with major components: nitrogen and phosphorus. As a result of the pH
adjustment, nitrogen and phosphorus, which are present in urine, react
with electrochemically generated iron solution and then accumulate in
the sludge by precipitation. All experiments were done under different
pH values for the evaluation of this novel EC nutrient removal process.
The effect of the EC treatment on the removal of nutrients was followed
by total nitrogen and phosphate measurements and Fourier transform
infrared spectroscopy (FTIR). The effects of treatment parameters (pH,
iron/phosphate, iron/nitrogen, and iron/nutrient ratios) on the
performance of the EC treatment were also examined for the evaluation of
applicability of this novel EC method for the treatment of yellow
waters. The results show that the pH increase improved phosphate removal
efficiencies at definite molar nutrient ratios. The phosphate removal
efficiency was approximately 98% at pH 8 for 1:1 of iron/nutrient molar
ratio and on the other hand, nitrogen removal was only 21% at pH 8 for
4:1 of iron/urea molar ratio. Total organic carbon (TOC) removal
efficiency was reached to 26% of the process. FTIR adsorption spectra
were discussed for the sludge obtained.
