Time series analysis of ground water table fluctuations due to temperature and rainfall change in Shiraz plain

This research aims at forecasting ground water fluctuations due to temperature and rainfall effects using time series and cross-correlation analysis. Box Jenkins’s time series model was analyzed and the best one for Shiraz plain proved to be multiplicative seasonal. This model was used to forecast the future ground water fluctuations as affected by long term temperature and rainfall data. Results showed that...

Removal of nitrogen from ammonium-rich synthetic wastewater in an upflow column type anammox reactor

The aim of this study is to illustrate the efficiency of nitrogen removal from synthetic wastewater using a fixed-bed anaerobic ammonium oxidation (anammox) reactor. A continuous fed flow reactor was inoculated with upflow anammox and fed with synthetic wastewater. The reactor was operated for 75 days without pH control. The maximum ammonium and nitrite removal efficiencies achieved were 95 and 97.5%, respectively. The...

Interference of organic waste pollution from municipality cattle market/slaughter on adjacent stream/ground water quality

Chemical contaminants from animal droppings and other organic wastes, nonpoint source (NPS) runoff and abattoir waste water at the municipality cattle market/slaughter lot, Uyo, Nigeria, which increased detritus litter or are leached to ground water, were investigated on the facility borehole and adjacent stream water. Statistical analysis of samples’ physico-chemical composition using SPSS ver 17 package,...
