The
study aimed to analyze the physicochemical parameters and
microbiological assessment of effluent from WWTP on vegetable in
Sebkha. The results of physicochemical analysis presented in
this work showed that wastewater temperatures were 28.7°C. The
pH varies between 7.4 and 7.9. The salinity of the effluent was
observed by measuring the electrical conductivity and chlorides
with respective maximum values of 3290 µS/cm and 1262.1 mg/L.
The microbiological results show that the microbial load of
fecal coliforms and fecal streptococci is very important. The
levels of fecal coliforms and fecal streptococci ranged between
1.5 x104 ufc/100 mL to 2.7x104 ufc/100 mL and 1.8x104 ufc/100 mL
to 3x104 ufc/100 mL respectively. The presence of very high
indicator organisms of fecal contamination is undoubtedly a
threat to market gardeners, children of farmers, retailers and
consumers. The application of Principal Component Analysis
indicates that two groups of wastewater: a group of waste water
from largely industrial effluents characterized by high
alkalinity and high salinity and another from domestic effluents
consists of very high levels of fecal loads and ammonium
phosphates.
