Background & Aims of the Study: One of the most important pollutants in drinking water, air and soils is heavy metals. It is very harmful for humans and other live organisms. The purpose of this study was the usage of a co-composting process for removal of heavy metals from municipal solid waste and sewage sludge. Materials and Methods: This experimental study was a condu...
Due to the growing population of Earth, problem providing food comes fore. Therefore, search for new, economically available sources trace elements crop production is relevant. One these potential blast-furnace sludge: highly dispersed metallurgical waste, industrial processing which difficult due its high zinc content. We studied effect sludge on rapeseed plants in laboratory, greenhouse, and ...
Abstract Pyrolysis is a pathway for hydrogen reproduction from sewage sludge. The critical problem in the indirect pyrolysis process lower heat transfer performance furnace. circulation of media controls pyrolizer (e.g., carriers (HCs) form alumina balls), which essential determining and ultimately yield. temperature HCs amount yield are low because required vessel not satisfied. This study inv...
A mathematical heat transfer model for the prediction of transient heating of the slab in a direct-fired walking beam type reheating furnace has been developed by considering the nongray thermal radiation with given furnace environments. The furnace is modeled as radiating nongray medium with carbon dioxide and water with five-zoned gas temperature and the furnace wall is considered as a consta...
