Bio-solids From Wastewater Treatment Plant in Uganda do not Meet Minimum Standards for Land Application

Published

on

Land application of bio-solids is the cheapest and most convenient method of disposalof bio-solids worldwide, but it is unclear if the bio-solids in Uganda are safe for land application. The objective of this study was to establish the impact of ageing on quality and safety of bio-solids from Bugolobi Wastewater Treatment Plant (BWTP) in Uganda’s capital city, Kampala, for land application. Nine out of 14 beds in each of the four blocks (Block 1: fresh bio-solids; Block 2: settling bio-solids; Block 3: maturing bio-solids and Block 4: mature bio-solids) were randomly sampled for quality and for bio-safety. For quality, bio-solids were analysed for electrical conductivity (EC), N, P and K concentrations, and their respective stocks; organic matter (OM) content and bio-solid  organic  carbon  (BOC)  stocks.  For  bio-safety,  bio-solids  were  screened  for Escherichia  coli  and  Salmonella.  

Ageing of bio-solids had a significant impact on EC; OM and E. coli. The EC was highest in the mature bio-solids and lowest in fresh bio-solids. Similarly, microbial counts were highest for E. coli in the mature sludge and lowest in the fresh bio-solids. Out of the 36 bio-solid samples, one tested positive for salmonella. The bio-solids are neither safe for use as agricultural input, nor for general release into the environment.
