Heavy Metal Determination in the Bottom Solid Waste Ash Produced from Sabah and Shuaiba Hospital Incinerators in Kuwait

Abstract

Abstract:In Kuwait, there is growing concern over the disposal of wastes produced by hospitals since hospital wastes contain hazardous and infected wastes. All hospitals in Kuwait have adopted incineration as an alternative method to dispose of their wastes. Due to inefficient combustion of hospital incinerators, the Kuwaiti government decided to shut down all hospital incinerators, while the Sabah Incinerator (SAHI) and Shuaiba Incinerator (SUHI) were kept running. This study was initiated to focus on the determination of heavy metals in the bottom ashes produced by the SAHI and SUHI incinerators. Bottom ash was collected over a period of one year and heavy metals were determined. They were shown variation in their concentrations due to the initial waste composition and the operational procedures of the hospital incinerators.

Use of Irradiated Flocculants for Wastewater Treatment

“…The greatest effect at deleting petroleum products from a surface of waste water due to specially organized adsorption is observed for highly anionic flocculant M 345 at its modification under MWR and using basalt fiber as a sorbent. Besides, formed covers can be deleted from the waste water by various ways, such as filtering [13], scrapers [14], basalt fiber and other materials widely used in treatment [15].…”
