Nitrate removal from Cetina surface water by using bacteria attached to Lewatit M600
The applicability of the bacteria attached to the exhausted exchange resin - Lewatit M600 (NSI) for fast and efficient nitrate removal from the surface Cetina water (SCW) was investigated. The investigated system enables simultaneous bonding of nitrate and degradation of bonded nitrate ions. The nitrate adsorption on NSI was described with the Freundlich isotherm. The nitrate (50-200 mg NO3¯-N/L) was completely removed from the SCW during 4-7 hrs at pH = 7.2 and 25 °C under anoxic conditions. Activation energy, EA and Arrenius factor, Ar for nitrate reduction were 11.40 kJ/mol and 1790.05 mg NO3¯-N/Lh, respectively. The required MetOH:N ratio was 2.5:1 although the denitrification process was faster in the presence of increased MetOH:N ratios.
