Abstract
Waste water recycling is one of the ways of conserving water resources. This work focused on the construction of a slow sand filtration medium constituting gravel layers, sharp sand layer and activated charcoal, with an objective of evaluating the performance of activated charcoal in a slow sand filtration medium where waste water samples were allowed to filter through the medium. Some water quality test such as the Colour, Conductivity, Odour, Taste, Temperature, Turbidity and all the chemical parameters such as Calcium, Fluoride, Hardness, Iron, Magnesium, Nitrate, pH, Residual Chlorine, Sulphate, Total Dissolved Solid and Chlorides were carried out on the recycled water to determine their qualities. The results were compared with the World Health Organization (WHO) and Nigerian Standard for Drinking Water Quality (NSDWQ) guideline limits. The results show that activated charcoal with slow sand filter, can be used at industries and manufacturing processes but not for drinking purposes. So, our target is to recycle waste water with the intention to provide better and healthy water at very low cost, which can be affordable to anyone. It is therefore recommended for households to adopt it as a homemade water purifier as low maintenance treatment process is required. The recycled water can be used for multi purposes.
