Abstract
The study on odour annoyance of wastewater
from Garri, Akpu and Starch process methods was carried out in Makurdi using a
laboratory scale SFWS-v and evaluating the performance by removal efficiency of
odour. Structured questionnaire on seven rated odour annoyance level was used
to evaluate the levels of odour annoyance by rourty respondent within the
vicinity of cassava processing plants. Descriptive statistics of mean, StDev,
correlation and multivariate statistic was used to attest the degree of
variation and similarities that exist between tested process methods, there was
100% response by the respondent comprising 37,5% male and 62.5% female. The
odour annoyance was skewed toward increasing rating of annoyance for
non-treated wastewater and skewed toward decreasing rating for treated
wastewater, the treatment facilities have reduced the percentage response to annoying
(25%) and quite annoying (35) of non- treated water to below 5% of treated
wastewater for the three cassava processes. In consequence, response to not
annoyed and very little annoyed was increased from below 5% for non-treated
water to 20% for not annoyed and 45% for very little annoyed on the average for
treated water.
