In this study, water treatment sludge was investigated through batch modes for the treatment of saline water to meet livestock drinking consents. The water quality was assessed using water quality index (WQI).The kinetic data was best described by the Pseudo – Second – Order model and the equilibrium isotherm by the Freundlich model. The maximum re...

The adsorption of copper, iron and nickel ions from an aqueous solution using Makoro granite clay brick waste through batch and fixed – bed column modes was investigated. The adsorbent was characterised using X-Ray Fluorescence, X-Ray Diffraction (XRD), Thermogravimetric Analysis, and Scanning Electron Microscopy (SEM). XRD results revealed crystal...

The pollution of surface and groundwater by heavy metals from industrial effluents is of great concern to the environment. In this study, the adsorptive removal of iron, nickel, and copper from the aqueous solution was investigated through batch and fixed-bed column mode using Cement Brick Waste (CBW) as an adsorbent with particle size in the range...

In this study, we present the performance of acid washed copper smelter slag for the adsorption of phosphates and sulphates from wastewater. The aim of the study was to investigate the removal of phosphates and sulphates from wastewater using acid washed copper smelter slag at batch scale by exploring influences of different variables. The leachate...

Effluents from industries frequently contain a variety of chromium ions such as hexavalent chromium and trivalent chromium which can adversely pose threats to terrestrial and aquatic life. Hexavalent chromium is more toxic than trivalent chromium thus need to be removed from effluents. Adsorption is a water and wastewater treatment technology which...

Shortage of water for agriculture has resulted in the need to explore the use of wastewater for irrigation, however this can pose a health problem to the people emanating from the produced food as a result of the accumulation of pollutants. The purpose of this research was to investigate the accumulation of some heavy metals and bacteriological ind...
