Abstract

The problem of water Scarcity, water pollution and cost of accessing water for domestic needs have become growing concerns to the ever increasing global population. Waterwaterremediation has long been accepted as a viable option to mitigate water scarcity.

This research examines the potentials of an environmentally friendly technique of using local but modified tropical plant materials in remediation of greywater for re-use.

Column adsorption experiment was conducted using synthesized and characterized Biochar and Activated Carbon made from Shea tree (Vitellariaparadoxa), African Mahogany tree (KhayaSenegalenses) and the Fig tree (FicusSycomous) as filter media in constructed filter columns made from polyvinyl chloride pipes.

Greywater Samples from Ahmadu Bello University Zaria‘s student hostel were passed through these filters at a hydraulic loading rate of 0.033m³/m²/day for a period of 21 days.

Introduction

With the continuous annual increase in the world population (lowest increase being 1.1%) there is need to manage our natural resources.

Water, which is one of these basic resources for human survival and socioeconomic development, needs to be managed efficiently.

The United Nations has estimated that the use of water has increased six fold in the 20^th century and that by the year 2025, about 1.8 billion people will have absolute water scarcity conditions

(with an annual water supply of less than 500m³ per capita) and also that two third (2/3) of the world population will live under water stress (with an annual water supply of less than 1700m³ per capita) (U.N-Water Report, 2006).
