This book highlights peer reviewed articles from the 1st International Conference on Renewable Energy and Energy Conversion, ICREEC 2019, held at Oran in Algeria. It presents recent advances, brings together researchers and professionals in the area and presents a platform to exchange ideas and establish opportunities for a sustainable future. Topics covered in this proceedings, but not limited to, are photovoltaic systems, bioenergy, laser and plasma technology, fluid and flow for energy, software for energy and impact of energy on the environment.

One technology for environmental control and waste remediation which has great potential is contaminant removal and separation with supercritical fluids (SCFs) or supercritical fluid extraction. In order to take advantage of this technology, both a fundamental understanding of phase equilibria and applicable engineering design data are required. This report documents an extensive study into both aspects culminating in the design and economic evaluation of an SCF regeneration process for granular activated carbon. Results include: solubility of model compounds, cosolvent effects on solubility, vapor pressure measurements, spectroscopic measurements, and models for SCF phase equilibria. Charts, tables and graphs.

This monograph provides comprehensive coverage of technologies which integrate adsorption and biological processes in water and wastewater treatment. The authors provide both an introduction to the topic as well as a detailed discussion of theoretical and practical considerations. After a review of the basics involved in the chemistry, biology and technology of integrated adsorption and biological removal, they discuss the setup of pilot- and full-scale treatment facilities, covering powdered as well as granular activated carbon. They elucidate the factors that influence the successful operation of integrated systems. Their discussion on integrated systems expands from the effects of environmental to the removal of various pollutants, to regeneration of activated carbon, and to the analysis of such systems in mathematical terms. The authors conclude with a look at future needs for research and develoment. A truly valuable resource for environmental engineers, environmental and water chemists, as well as professionals working in water and wastewater treatment.
