Advanced nitrogen removal using pilot-scale SBR with intelligent control system built on three layer

YANG Qing, WANG Shuying, YANG Anming, GUO Jianhua, BO Fengyang

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 1, Pages 33-38 doi: 10.1007/s11783-007-0006-4

Abstract: Since eutrophication has become increasingly severe in China, nitrogen and phosphorous have been the concern of wastewater treatment, especially nitrogen removal. The stabilization of the intelligent control system and nitrogen removal efficiency were investigated in a pilot-scale aerobic-anoxic sequencing batch reactor (SBR) with a treatment capacity of 60 m/d. Characteristic points on the profiles of dissolved oxygen (DO), pH, and oxidation reduction potential (ORP) could exactly reflect the process of nitrification and denitrification. Using the intelligent control system not only could save energy, but also could achieve advanced nitrogen removal. Applying the control strategy water quality of the effluent could stably meet the national first discharge standard during experiment of 10 months. Even at low temperature ( = 13vH), chemical oxygen demand (COD) and total nitrogen (TN) in the effluent were under 50 and 5 mg/L, respectively.

Situational Awareness in Construction and Facility Management

Burcu Akinci

Frontiers of Engineering Management 2014, Volume 1, Issue 3, Pages 283-289 doi: 10.15302/J-FEM-2014037

Abstract: Engineers and managers involved in construction and facility/infrastructure operations need situational awareness about the as-is conditions when making daily decisions and developing short- and long-term plans. Yet, currently situational awareness of engineers is often challenged due to missing data and the available data not being in a format that is easily accessible and actionable. Advances in reality capture technologies, such as 3-dimensional (3D) imaging, in-situ sensing, equipment on-board instrumentation and electronic tagging, streamline the capturing of the as-is conditions on job sites. The data collected from these technologies, integrated with building information models depicting the as-planned conditions, can help in creating and storing the history of as-is conditions of a facility to support a variety of decisions that engineers and managers need to make. While the opportunities associated with integrating building information models and data capture technologies are compelling, several challenges need to be addressed through research for effective usage of these technologies. Such challenges include assessing the accuracy of the data collected at the field, developing and evaluating data processing and data fusion approaches, formalizing integrated representation of building information models and sensor and other relevant data, and investigating and developing approaches for analyzing and visualizing such integrated information models. This paper provides examples of recent research studies done at the Civil and Environmental Engineering Department at Carnegie Mellon University that demonstrate opportunities associated with integrating building information models and sensor information for facility operations.
