دانلود کتاب Fundamentals and Control of Nitrification in Chloraminated Drinking Water Distribution Systems - Manual of Water Supply Practices, M56

Nitrification is a microbiological process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate. Nitrification can be problematic in potable water systems that use chloramines for residual (secondary) disinfection. This manual summarizes existing knowledge and provides updated information on the current practices of water suppliers and issues related to nitrification; provides water utilities with the latest information on nitrification in water distribution systems; provides information to help utilities maintain a chloramine residual in tap water; and helps utilities effectively mitigate nitrification episodes that may occur in their systems.
