Removal of COD and color from hydrolyzed textile azo dye by combined ozonation and biological treatment
TL;DR: The toxicological results of the tests with Daphnia Magna showed that there is an increase in toxicity after ozonization and a decrease after submitting the ozonized synthetic wastewater to biological treatment with a biofilm.
Journal ArticleDOI
Toxicity of textile dyes and their degradation by the enzyme horseradish peroxidase (HRP).
TL;DR: The tests for toxicity towards Daphnia magna showed that there was a reduction in toxicity after the enzymatic treatment, however, the toxicity of the textile effluent showed no change towards Artemia salina after the enzyme treatment.
Journal ArticleDOI
Study of lead (II) adsorption onto activated carbon originating from cow bone
TL;DR: In this paper, the adsorption of lead (Pb 2+ ) onto activated carbon (AC) originating from cow bone, chemically modified with HNO 3, was investigated.
Journal ArticleDOI
Responding to customer enquiries in make-to-order companies : Problems and solutions
TL;DR: In this article, a model based on a chi-squared analysis of data on past enquiries is proposed to divide the market into sectors of similar orders, and a strike rate matrix for each sector giving the probability if winning orders in that sector as a function of the price and lead time quoted.
