Hazardous Organic Pollutants in Colored Wastewaters is available to download free in pdf / epub format.
The manufacturing and the application of organic dyes involve the production and the handling of many organic compounds hazardous to human health. Many of these substances are considered toxic, even carcinogenic. Over the past couple of decades, manufacturers and users of dyes have faced increasingly stringent legal regulations promulgated to safeguard human health and the environment. So, there is a clear need to treat dye wastewater prior to discharge into the primary effluent. The limitation of traditional wastewater treatment technologies (biological and physical), such as low rate, disability to degrade many of recalcitrant organic dyes and the production of secondary waste which demands further treatment, can be overcome by the utilization of advanced oxidation processes (AOPs). These wastewater treatment methods are considered as low- or even non-waste generation technologies. Generally, AOPs can be broadly classified concerning the way of OH radicals generation into chemical, photochemical, photo catalytic, mechanical and electrical technologies.
