BIOLOGICAL REMOVAL OF NITRATE IN THE WATER SUPPLY USING THE COCONUT ENDOCARP AS CARBON SOURCE
Groundwater quality has been deteriorated as a result of the intensification of human activities over the years. Groundwater contamination by nitrate is one of the effects of this degradation, a socio-environmental problem that affects many regions of the world. Developing techniques for nitrate removal in water is intended to eliminate or reduce the concentration of this compound, and those that involve biological processes have produced economic and environmental advantages. This study proposes a technology for biological removal of nitrate in water supply for humans consumption, using the endocarp’s coconut as a carbon source and bacteria support. The experiments were performed in pilot scale anoxic chambers, testing different areas of the substrate surface. Results showed high rates of nitrate removal during the monitoring period, noting the occurrence of denitrification after the beginning of system operation. The best performance was achieved in the treatment system containing increased substrate surface area, indicating that the decrease in the endocarp size contributed to increased bacterial activity, improving the ability to remove nitrate.Keywords: denitrification, nitrate removal, water treatment.
