Abstract:
The treatment of wastewater and monitoring of its toxicity is essential before discharging it to
the environment. This study focuses on assessing the toxicity of wastewater following
treatment using the electrochemical peroxidation process (ECP). Three categories of low-cost
toxicity assays were used based on plant cells, microorganisms and invertebrates, all of which
do not require ethical approval or a special licence. In addition, a novel cost-effective device
was developed for assessing wastewater toxicity at low concentrations.
In Chapter 2, the problem of high turbidity of the ECP-treated samples is addressed, by
accelerating particulate settling of the existent compounds. This was achieved by storing the
ECP treated samples at low temperatures. This is an essential step for enhancing the clarity of
the processed samples in order to improve the performance of the toxicity assays. Cont/d.
