Treatment of textile wastewaters using combinations of biological and physico-chemical methods

Popular Abstract in Swedish En vän till mig berättade hur hon hade köpt en färgglad t-shirt vid en resa till Indien. Första gången hon hade den på sig började det att ösregna och ett par minuter senare fanns det snopet nog mer färg i de kringliggande vattenpölarna än i tyget. Lyckligtvis har de flesta färger idag bättre kvalitet än så. De färger som används inom textilindustrin är utvecklade för aConsiderable amounts of water and chemicals are used in the textile industry, and the presence of dyes in the wastewater is a problem of environmental concern. Synthetic dyes are designed to resist light, water and chemicals to improve the quality of the textiles; however, these properties also contribute to their persistence in the environment. The existence of wastewater treatment plants in conn

Visualization of Ergonomic Guidelines – Development and Evaluation of Prototypes

This study attempts to discover how ergonomic guidelines should be visualized in order to make it easier and more interesting to find and interpret the guidelines throughout the construction process. A prototype, visualizing ergonomic guidelines on the intranet, has been developed and evaluated at a company that produces cars for the global market. The results show that the visualization of ergono

Characteristics of Particle Emissions at Paint Manufacturing

The handling of pigments and powders in paint manufacturing cause emissions of airborne particles. A great variety of substances occur. Previous studies (Bohgard et al., 1994) of simulations of pouring of pigments, which occur in small scale weighing procedures, showed typically bimodal size distribution including a sub-micron and a super-micron mode.The objective of the study was to get detailed

Posture and Comfort Analysis of Car Drivers

In the EC project, ANNIE (Application of Neural Networks to Integrated Ergonomics) the aim is to develop a human simulation and ergonomic evaluation tool based on a neural network. Recorded movement patterns from subjects, performing tasks in real environments, will train the network. The net will control a mannequin, to perform human-like movements. The human model will be placed in different vir
