A Study of the Industrial Waste Incorporating in Glass

Abstract

The paper presents a study of the industrial waste incorporating in glass in order to obtain decorative colored glasses. The influence of iron and chromium oxides from waste amount is discussed. The samples properties such as density, thermal expansion coefficient and viscosity are investigated. Including different oxides of heavy metals (obtained from sludge that contains chromium and iron) into the vitreous system leads to the obtaining of several decorative glasses. Their colour varies widely, to the added quantity and the atmosphere of the work place.

Impact of Heavy Oil Sewage Components on the Performance of Coagulated Particles

“…Meanwhile, the adherence between particles and sewage liquid is depends on the change of components (ions, oil) and pH in sewage. Therefore, the study of the impact of different components and pH on the wettability of particles surface during coagulation process is of great significance to reveal the mechanism of coagulation and air flotation process [3][4][5]. Based on the wettability of the particles surface analysis during coagulation process, the influence of the main cation (Ca 2+ , Mg 2+ , Fe 2+ , Fe 3+ ), pH and oil content in heavy oil sewage on the surface wettability of the coagulation particles were studied in this paper, and mechanism was discussed.…”
