Abstract

Public health is presently being threatened as a result of the inhabitant’s exposure and exposed waste handlers to untreated sludge in Bwari, Abuja arising from pit toilets and septic tanks. Universal, unhygienic conditions are answerable to above three million deaths yearly, with low sanitation level as main cause in developing countries and slurry from under developed nations contain high parasite concentration with small heavy metal content, therefore analysis and field survey required in achieving a viable sludge management in developing nations are investigated. Laboratory analysis of septic sludge samples without additive reveals lime (calcium oxide) addition and wood ash active in bringing down the Ascaris count to zero value. Wood ash yielded better results with roughly half of the latter’s amount added to accomplish Og-1 value of the last Ascaris count, whereas lime addition generates an alkaline environment that is not profitable to microorganism survival besides diminishes odors. In addition for Human sewage without additive, carbon values are higher for all the three zones followed by potassium while phosphorus is the least. High Ascaris ova count without additive, null after lime additive and ash additive were added. Household using water closet (WC) is higher for north-south and west-east (literate zone) while household with pit toilet greater in the central zone (illiterate region). Based on this study lime and additive are capable of bringing Ascaris count to null besides dismiss odor which in turn lessen health problems and related risks.
