Detection of Ammonia-oxidizing Bacteria (AOB) in the Biofilm and Suspended Growth Biomass of Fully — and Partially-packed Biological Aerated Filters

Fatihah Suja’ Universiti Kebangsaan Malaysia Malaysia 1. Introduction Nitrification is a two step process namely ammoniacal oxidation and nitrite oxidation. Oxidation of ammonium to nitrite is carried out by autotrophic bacterium mainly Nitrosomonas (e. g. N. europaea, N. oligocarbogenes) and Nitrosospira while conversion of nitrite to nitrate is performed by Nitrobacter (e. g. N. agilis, N. winogradski) and Nitrospira. However, […]

Interpolation

Interpolation is necessary to produce digital models from Lidar point cloud. The simple idea of the interpolation is referred to the nearest neighbor interpolation method to estimate the elevation (Maune, 2007). It searches for the set of nearest points, thus the new elevation value is selected as the same value of the nearest point instead of taking the average of […]
