ABSTRACT
The indiscriminate release of effluents without any type of treatment,
or previous treatment without adequate disinfection, can cause several
inconveniences for the water body and society, including water-borne diseases.
In the present study, the physicochemical and biological aspects of three WWTPs (Wastewater Treatment
Plants) operated with UASB
(Upflow Anaerobic Sludge Blanket) technology in Juazeiro do Norte were analyzed
in order to verify the state of Ceará State legislation, compliance with
standards for the release of domestic effluents into bodies’ receptors. In the
research, it verified that the stations did not meet the effluent
release standards for TSS (Total Suspended
Solids) and removal of Escherichia coli in several analyzed months. It also verified that the UASB
stations need a post-treatment in order to assist in the process of removal of
organic matter and pathogens.
KEYWORDS
