Autotrophic Nitrogen Removal from Low Concentrated Effluents

Javier Adrián Sánchez Guillén is originally form Panamaand got his Chemical Engineering degree from the Universidad Autónoma de Puebla, Mexico. Afterwards, he started working at the National Bureau of Drinking Water supply and Waste Water treatment of Panama. To expand his knowledge in the water sector he came to the Netherlands to obtain his Master in Sanitary Engineering at UNESCO-IHE. Hewas awarded a Fulbright fellowship Hubert Humphrey program in Water Quality-Watershed Management which he covered at Cornell University, USA, as well as a scholarship from the Japan International Cooperation Agency (JICA) and the International Lake Environment Committee Foundation (ILEC) to study Environmental Education Focused on Fresh Water Environment which he covered at Shiga University in Japan. After completing his master's degree, Javier worked at the Technological University in Panama, where he was appointed as a Lecturer in the subjects of drinking water treatment and wastewater treatment in the Master of Science program. He returned tothe Netherlandsfor aPh.D. on the topic of autotrophic nitrogen removal from low concentrated effluents. The main objective of this research was to study system configurations and operational features for post-treatment of anaerobic effluents in the mainstream.Javier plans to continue with his research in Anammox-based technology with the purpose of contributing with the development of bioprocess for nitrogen pollution control. After about 22 years of experience in water treatment, he is currently working at the National Bureau of Drinking Water supply and Waste Water treatment of Panama.

1 Pollution control of dissolved inorganic nitrogen in urban zones through sewage treatment. 2 Short-term effects of organic carbon source, chemical oxygen demand/N ratio and temperature on autotrophic nitrogen removal. 3 Long-term performance of the Anammox process under low nitrogen sludge loading rate and moderate to low temperature. 4 Anammox process in a closed sponge-bed trickling filter. 5 Autotrophic nitrogen removal over nitrite in a sponge-bed trickling filter under natural air convection. 6 Evaluation and Outlook.
