dc.description.abstractLubigi fecal sludge and waste water treatment plant currently operates using non-conventional technology for treatment with drying of fecal sludge by evaporation and percolation. Although the plant has the capacity to manage human excreta from both the onsite and offsite sanitation facilities, there is high solid loading due to the incoming large volumes of waste what exceed the design capacity of the plant and a problem of longer drying periods than intended. There is need for optimum utilisation of the sludge drying beds and the treatment plant all together. This study aimed at assessing the use of water treatment sludge granules coated with poly aluminium chloride from water treatment sludge to enhance dewatering of fecal sludge. The raw fecal sludge samples were analysed for parameters of pH, electrical conductivity, moisture content and total solids. Water treatment sludge was also characterised using the X-ray fluorescence technique so as to determine whether the content of aluminium oxide present is suitable for the preparation of poly aluminium chloride. Water treatment sludge granules coated with poly aluminium chloride showed potential in dewatering of fecal sludge with the lowest moisture content of 25.3% and maximum total solids of 74.7% achieved with the 4g/l dosage.
