<b>Whole Effluent Toxicity (WET) Test in Industrial Effluent Management: </b><b>Toxicity Reduction Evaluations in Chemical Industry </b>

C.o.d Reduction of Reactive Dyeing Effluent from Cotton Textile Industry

The present study focuses on the improvement in the effluent treatment for the effluent generated from a cotton textile industry employing three reactive dyeing methods viz., Exhaust method, Pad-Dry-Cure method, and Pad-Batch method. Stabilisation pond, aeration tank, and aerobic biological treatment (using E-Coli type bacteria) are simulated in the laboratory in a series operation. Results rev...

Industrial Effluent Treatment by Novel Biological Reactor

1.1 Textile industry Textile industry is the largest industrial employer in the country, contributing to 6% GDP (Gross domestic product), 16% of export and about 18% of industrial production. The textile industry plays an important role in Indian economy. It contributes to 9% of excise collection, 30% of export revenue and 18% of employment in industrial sector. Since global trade in textile an...

Effluent-free papermaking: industrial experiences and latest developments in the German paper industry.

Thanks to multiple recirculation of process water, the German paper industry has succeeded in decreasing the specific fresh water demand from an average of 50 m3/t thirty years ago to 13 m3/t today. Although the increasing closure of white water loops creates many problems, it is bound to be part of the German paper industry's ongoing development. For a few years, in the production of packaging...

Bioequivalence Approach for Whole Effluent Toxicity Testing

Increased use of whole effluent toxicity (WET) tests in the regulatory arena has brought increased concern over the statistical analysis of WET test data and the determination of toxicity. One concern is the issue of statistical power. A number of WET tests may pass the current hypothesis test approach because they lack statistical power to detect relevant toxic effects because of large within-...
