물환경연구재단(WERF)이 에너지 연구를 향상시키기 위한 세 개의 새로운 연구과제를 시작했다고 발표했다. 첫 번째 프로젝트는 ‘워터와츠(WaterWatts): 폐수 전력계측 데이터에 대한 현대적인 시각’이라는 제목으로, Brown and Caldwell이 진행을 맡고 있다. 시설들은 점점 더 에너지 효율성을 추구하는 상황으로, 이를 위해서는 공정에 필요한 전력에 대한 이해가 중요하다.

 

 

 

The Water Environment Research Foundation (WERF) has announced that it is launching three new studies that seek to advance energy research.

 

The first project, "WaterWatts: A Modern Look at Wastewater Power-Metering Data (ENER15C15)," was awarded to Brown and Caldwell. As utilities strive to become more energy efficient, it is important to understand the electric power required by processes, particularly those involving aeration.

 

Most studies to date have not used disaggregated power data to calculate energy intensity, instead relying on whole plant (black-box) estimates or modeled results. The main objective of this study is to evaluate disaggregated power-metering data from over 40 water resource recovery facilities.

 

The second project, "Energy Recovery from Thermal Oxidation of Water Solids - State of the Science Review (ENER13T14)," will also be conducted by Black and Veatch. This research will examine the energy potential from the thermal oxidation of biosolids and other residuals by documenting the effectiveness of energy or heat recovery from up-to-date thermal oxidation units with combined heat and power.

 

The research team will determine the potential for renewable energy recovery from thermal oxidation of wastewater residuals at water resource recovery facilities practicing incineration nationwide and compare the triple bottom line value of energy recovered from biosolids by thermal oxidation to the same units of energy obtained from coal.

 

The third project, "Controlled Laboratory Investigation of Siloxane Adsorption Media and Variables Impacting Performance (LIFT7T14)," will evaluate the performance of four types of solid sorbents commonly used to remove siloxanes from digester gas. The results of this research performed by Virginia Tech will provide information that can be used to more reliably and cost effectively design, install and operate energy recovery processes at water resource recovery facilities that use biogas as a renewable energy resource.
