Due to population growth, there is an increase in the tendency of water resource degradation. One of the biggest polluters is the practice of dumping industrial and domestic effluents without any treatment on the watercourse. The utilization of effluents is an alternative to minimize the inadequate waste dump, thus avoiding the overload on the treatment system as well as cutting down costs and expenses. This work’s objective is to evaluate the application of reverse osmosis in a food industrial effluent, in physicochemical and toxicological terms. A reverse osmosis technical application was conducted and then the effluent was examined, before and afterward, in terms of pH, Turbidity, Colouring, Conductivity, Dissolved Oxygen, Total Organic Carbon, and Total Nitrogen as well as a toxicological evaluation (Allium cepa). According to the obtained result, it can be identified that the technique of reverse osmosis showed treatment efficiency when applied to the effluent containing coloring and soy isoflavones, with regards to the physicals and chemical evaluation. In terms of toxicological evaluation, with respect to the radicular development, the treated effluent (permeate) showed a radicular growth, once the raw effluent did not develop any root.

This study assessed the heavy metal compositions and chromosome aberrations induced by cassava industrial effluent using Allium cepa meristem assay. Effluent collected at the point of discharge from the cassava processing factory located at Lokoja, Kogi State Nigeria was analyzed for quantity of Cadmium (Cd), Chromium (Cr), Copper (Cu), Manganese (Mn), Iron (Fe), Nickel Ni, Cobalt (Co) and Lead (Pb) using Atomic Absorption Spectrophotometer method. Onion (Allium cepa) roots were allowed to grow in beakers containing different concentrations of cassava industrial effluent (i.e. 25%, 50%, 75% and 100%) and the control for 24 hours. Harvesting of the tips for chromosome observations was carried out between 8:00 to 9:00am West Africa Time. Data pooled under X400 magnification of the light microscope for mitotic phases and chromosome aberrations were analyzed using Analysis of Variance (ANOVA) while means with significant difference across concentrations were separated using Duncan Multiple Range Test (DMRT). The results revealed that only Cadmium (Cd) and Lead (Pb) concentrations in the effluent were higher than the minimum values recommended by World Health Organization. The effluent also produce binucleate cells, variant chromosomes, C-mitosis, vacuolated cells, tripolar anaphase and anaphase bridge which suggests the mutagenic and cytotoxic activities of the industrial effluent. The decrease in the Mitotic Indices (MI) of effluent-treated root cells compared to the control indicates mito-depressive ability of the effluent at every concentration. Regular monitoring of industries for compliance to treatment of effluent before releasing them into the environment is recommended.
