Low-temperature effects on the removal of soluble manganese in MnOx(s)-coated media systems
The purpose of this study was to investigate the role of low-temperature conditions in potentially impacting soluble Mn2+ removal in MnOx(s)-coated media systems. The study involved an extensive examination of water quality and process data for a 10-year period (2005–2014) from the Harwood's Mill Water Treatment Plant in Newport News, VA. Additionally, laboratory-scale shallow depth column ...

Prediction of dissolved oxygen in reservoirs using adaptive network-based fuzzy inference system
Predicting water quality is the key factor in the water quality management of reservoirs. Since a large number of factors affect the water quality, traditional data processing methods are no longer good enough for solving the problem. The dissolved oxygen (DO) level is a measure of the health of the aquatic system and its prediction is very important. DO dynamics are highly nonlinear and ...

Efficiency and reliability of membrane processes in a water reclamation plant
Performance of a water reclamation plant using ultrafiltration (UF) and reverse osmosis (RO) treating 280,000 m3/d of wastewater was evaluated over 1 year. Statistical analyses were performed on flow rate, temperature, pH, total suspended solids (TSS), total dissolved solids (TDS), biochemical oxygen demand (BOD5) and total coliforms. Variations in flow rates coincided with those in ...

Data center process water clean up - Case Study
The Problem : Super Computer Data Processing CPU Performance Loss Today’s Big Data reality depends on real world cooling efficiency. Even a super thin biofilm and/or deposits of any kind, cause real world cooling computer efficiency issues which cost real world dollars. AMSA, Inc. has set the standard for the last 23 years for the “smart”, or designed molecule approach for ...

Evaporator concentrates brine pond for about 1 cent per gallon
The Facility Eagle-Picher Industries has an 8-acre hazardous waste surface impoundment pond at its Electro-Optics Division plant in Quapaw, Oklahoma. The Problem By the time Eagle-Picher contacted Aqua-Chem ICD, the impoundment pond had been in use for more than 20 years and contained more than 5 million gallons. Environmental regulation required the plant to install a double liner in the ...

Characterizing water quality monitoring visualization with Hadoop and Google Maps
In water quality monitoring, the complexity and abstraction of water environment data make it difficult for staff to monitor the data efficiently and intuitively. Visualization of water quality data is an important part of the monitoring and analysis of water quality. Because water quality data have geographic features, their visualization can be realized using maps, which not only provide ...

ME40 Autonomous survey in bathymetric application - Case Study
Time: April, 2015 Location: Jiangxinzhou, Zhenjiang, Jiangsu Company: Shanghai Waterway Engineering Design and Consulting Co.,Ltd. Project Background: The survey project needs to measure the depth of Jiangxinzhou shallow water area in Yangtze River. The survey shallow area is 50m to the bank and 4km long, in which are full of crushed stones underwater. It is impossible for working ship to ...

Striving for a ‘One Utility, One Platform’ Approach at Halifax Water - Case Study
Streamlining data management, bringing down departmental silos and implementing 21st century water management at Nova Scotia's largest utility. “One of the difficulties with diving into the digital world is that you end up having an app for this, and then an app for that. The fact that Klir had so many different modules that can talk and communicate with each other was really appealing to ...

The use of shallow high resolution seismic reflection data to determine drilling locations at the Apache powder superfund site.
INTRODUCTION Groundwater contamination at the Apache Powder Superfund Site in Cochise County, Arizona includes dissolved nitrate-N and perchlorate. Past studies have determined that these contaminants migrate laterally from a perched zone underlying Apache Nitrogen Products, Inc. operating areas into the shallow aquifer of the San Pedro River alluvium (shallow aquifer). The base of both the ...
