Conditioning of aluminium-based water treatment sludge with Fenton's reagent: effectiveness and optimising study to improve dewaterability 总被引:6,自引:0,他引:6
Alternative conditioning of aluminium-based drinking water treatment sludge using Fenton reagent (Fe2+/H2O2) was examined in this study. Focuses were placed on effectiveness and factors to affect such novel application of Fenton process. Experiments have demonstrated that considerable improvement of alum sludge dewaterability evaluated by capillary suction time (CST) can be obtained at the relative low concentrations of Fenton reagent. A Box-Behnken experimental design based on the response surface methodology was applied to evaluate the optimum of the influencing variables, i.e. iron concentration, hydrogen peroxide concentration and pH. The optimal values for Fe2+, H2O2, and pH are 21 mg g(-1)DS(-1)(dry solids), 105 mg g(-1)DS(-1) and 6, respectively, at which the CST reduction efficiency of 48+/-3% can be achieved, this agreed with that predicted by an established polynomial model in this study. 相似文献

Transnational corporations (TNCs) invest enormous resources in their corporate social responsibility (CSR) programmes in the Niger Delta region of Nigeria. However, the effectiveness and mode of execution of these CSR activities have been subjects of continuing debate. This research was therefore carried out to elicit the perspectives of members of four local communities about the impact of the CSR interventions in the areas of health improvement and participation by members of the communities in the Niger Delta. Semi-structured questionnaires were self-completed by 182 members of the local communities in the Niger Delta; the respondents gave detailed feedback about community feelings for TNCs and their CSR efforts. The findings showed that the people generally have negative views towards the CSR practices of the TNCs. The result of a two-paired t-test showed this to be true for both men and women (P =?.888, CI 95). While 69.8% of the respondents felt that the TNCs did not bring any development to their community, 87.9% had high fear of getting a disease due to the community they live in; interestingly, 90.1% wanted to be involved in decisions concerning their communities. This research therefore proposes the increased use of health impact assessment as an approach to integrate health considerations and community participation into the evaluation and implementation of development programmes in the Niger Delta. Such an approach has the potential to make CSR initiatives more effective, transparent, and minimise the tensions between communities and TNCs. 相似文献
