Some physico-chemical and bacteriological parameters were analyzed for in the water samples of four different ponds located in Awka town both prior and after the rain to ascertain the impact of flood in these ponds and to establish whether the pollution was significant. Four samples were collected from each pond both before the rain and after making it a total of thirty-two samples. Twenty-seven parameters were analyzed for in each of the samples. The result revealed that twelve parameters exceed...
The applicability of electrocoagulation process for the treatment of battery industry wastewater ... more The applicability of electrocoagulation process for the treatment of battery industry wastewater and synthetic wastewater containing copper, lead, nickel and zinc was investigated in this work. The electrocoagulation experiments were carried out in an electrochemical reactor using a bipolar aluminum electrodes arranged in parallel. Experiments were carried out at voltage of 9, 12 and 15 volts, pH of 3, 7 and 10, initial ion concentration of 50, 150, 250 mg/l and contact time of 5, 10, 20, 30, 40 and 60 minutes. Effects of operating parameters such as contact time, pH, voltage, initial metal concentration were studied. For the single treatment of the synthetic wastewater, the optimum pH was 3 for copper, 10 for zinc and 7 for lead and nickel. The efficiency of removal increased with the increase in voltage, time and initial metal ion concentration. The process was successfully applied in the treatment of an industrial effluent from a local battery producing company where the concentr...

The extent of environmental and safety consciousness in Nigeria industries was reviewed in this paper. In Nigeria, industrialization and mechanization are increasing while occupational health problems are becoming prominent. On the same note, industrial development also brings, in its wake; problems of environmental pollution that often need abatement. Occupational Safety has been reported to be poor and still at infancy in Nigeria where most industries do not treat their wastes at all before discharging their effluents into the environment. The way forward for enhancing the safety and environmental consciousness were suggested. Awareness creation and enforcement are the two major steps to take to achieve a holistic safety and environmental compliance of industries.

The chemical composition such as insoluble carbohydrate, protein, fibre and residual starch content of the waste was determined. The substrate was then hydrolysed (acidic and enzymatic), saccharified and fermented using α-amylase/HCl, amyloglucosidase and Saccharomyces cerevisiae respectively. The results showed that combination of enzymatic and acid hydrolysis recovered much of the starch and cellulose than when either of them was used. Dilute HCl was more helpful in converting the cellulosic materials to reducing sugars. A total of 32.4% alcohol (2.7 g ethanol/15 g cellulosic waste) was obtained which indicates that cassava wastes actually could be transformed to chemicals for use as fuels, biochemicals, synthetic intermediates etc.
