Environmental Technical Verification Report for Ammonia Recovery Process


Book Description

Prepared by the Environmental Technology Evaluation Center (EvTEC), a CERF Service Center. This report describes the nature and scope of an environmental evaluation of ThermoEnergy Corporation's Ammonia Recovery Process (ARP) System, a method for recycling ammonia in wastewater. The data in this report were collected over a three-month pilot study.ØTests found that the ARP system is capable of removing 75?99% of the ammonia in the waste stream in a domestic wastewater treatment plant. The ARP System uses a series of absorption, evaporation, and crystallization steps to convert ammonia in wastewater into a commercial fertilizer, ammonium sulfate. The evaluation results clearly indicate that the ARP process is capable of achieving significant ammonia reduction under a range of environmental conditions




Smart Civil Structures


Book Description

A smart civil structure integrates smart materials, sensors, actuators, signal processors, communication networks, power sources, diagonal strategies, control strategies, repair strategies, and life-cycle management strategies. It should function optimally and safely in its environment and maintain structural integrity during strong winds, severe earthquakes, and other extreme events. This book extends from the fundamentals to the state-of-the-art. It covers the elements of smart civil structures, their integration, and their functions. The elements consist of smart materials, sensors, control devices, signal processors, and communication networks. Integration refers to multi-scale modelling and model updating, multi-type sensor placement, control theory, and collective placement of control devices and sensors. And the functions include structural health monitoring, structural vibration control, structural self-repairing, and structural energy harvesting, with emphasis on their synthesis to form truly smart civil structures. It suits civil engineering students, professionals, and researchers with its blend of principles and practice.
