Water depth effects on initial dilution of horizontally discharged cold water from an elevated outfall
In this study, the effect of bottom depth interaction on initial dilution differences of cold water discharge was experimentally investigated. 5°C cooled and dye tracer added cold water were horizontally discharged from a submerged circular nozzle from an elevated position into a stagnant and homogeneous receiving water in an experimental tank. Minimum initial dilutions were measured in cold ...

Water-flow accounts as part of material and energy-flow accounts in Germany
This paper [1] describes the concepts, data sources and methods of the water-flow accounts of the Federal Statistical Office as a part of the German material and energy-flow accounts [2]. The water flow accounting system represents in physical units the water flows, caused by economic activities, from nature to the economic system (raw materials), within the economic system, and from the economic ...

Quantifying the effects of channel change on the discharge diversion of Jingjiang Three Outlets after the operation of the Three Gorges Dam
The Jingjiang Three Outlets (JTO) are the water-sediment connecting channels between the Yangtze River and the Dongting Lake. The discharge diversion of the JTO plays a dominant role in the flood control of the middle–lower Yangtze River, Dongting Lake evolution, and ecological environment. After the operation of the Three Gorges Dam (TGD), the river channels downstream experienced dramatic ...

BP Schiehallion - produced water degasser
Client: BP Schiehallion - UK In July 2004 BP was required to take its produced water degasser on the Schiehallion FPSO offline for essential upgrade work. Without a replacement technology BP potentially faced a production shutdown during repairs. CETCO offered its CrudeSep® technology to BP as a temporary degasser vessel. In addition to oil and solids removal the CrudeSep® also acts as an ...

Characteristics of atomic oxygen produced by a pulsed streamer corona discharge
Various active species can be formed by a pulsed discharge in water, and these active species may play an important role in killing bacteria and degrading organic compounds. In recent years, interest in the formation of OH, O3 and H2O2 has grown enormously. The O is also a very powerful oxidant, but little research has been done on the oxygen radical. In this paper, production of atomic oxygen by ...

Hysteresis effects of suspended sediment transport in relation to geomorphic conditions and dominant sediment sources in medium and large rivers of the Russian Arctic
Preliminary analysis of long-term hydrological data shows that sediment dynamics of Russian Arctic rivers is largely affected by hysteresis effects in relation of water discharge to suspended sediment concentration (SSC). The role of large-scale geomorphic and geocryological conditions in sediment transport is still relatively understudied. This research aims to assess the links between ...

Numerical evaluation of flow regime changes induced by the Three Gorges Dam in the Middle Yangtze
The full operation of the Three Gorges Dam (TGD) has altered the downstream natural flow regime. Flow regime changes have resulted in profound influences on the utility of water resources and hence a large area with a riparian ecosystem including China's two largest freshwater lakes in the Middle Yangtze. Because of complicated flow regimes in this large-scale river–lake system, the TGD's ...

A satellite perspective on jökulhlaups in Greenland
Methods by remote sensing techniques were developed to locate potential jökulhlaup lakes and to assess the volume of water discharged. To locate potential jökulhlaup lakes, a time sequence of LandSat satellite imagery covering the area was investigated with spectral mapping techniques. The investigations showed how LandSat images can be used to map surface water, glacial ice, and ...

Water Purification Challenges: ZLD, EDI, COP systems
Applied Water Solutions was contacted by a client who planned to move their manufacturing facility to an area where there is strict limitations on water discharge. Working close with the client we created a process flow diagram (PFD) using multiple water purification technologies that provided pure water generation, water recycling capabilities and offsite disposal of solids. From the PFD we then ...

Case Study - Zero Liquid Discharge (ZLD) Application
Applied Water Solutions was contacted by a client who planned to move their manufacturing facility to an area where there is strict limitations on water discharge. Working close with the client we created a process flow diagram (PFD) using multiple water purification technologies that provided pure water generation, water recycling capabilities and offsite disposal of solids. From the PFD we then ...

Braided rivers: structure, types and hydrological effects
Braided rivers have been intensively analyzed mostly by geomorphologists. In the present study the approach to recognize braided channel types and effects with the special emphasis on flow partitioning has been applied. It is assumed that each braided channel represents the reach which is initiated with dividing of the single channel and completed below the confluence of the total multiplicity ...

Assessing the impacts of climate change on water resources in the Srepok watershed, Central Highland of Vietnam
The Srepok watershed in the Central Highland of Vietnam plays an important role in the economic development of the region. Any harmful effects of climate change on natural resources may cause difficulties for social and economic development in this area. The present study aims to predict and evaluate changes of water resources in the Srepok watershed under the impact of climate change ...

Cooling water temperature decreases at pharmaceutical facility case study
A large pharmaceutical manufacturer in Puerto Rico was experiencing severe scaling problems in its cooling tower/chiller systems resulting in decreased performance and efficiency. RYDLYME approach 1,320 gallons of RYDLYME circulated through the system for 24 hours followed by thorough water flush. RYDLYME results After the 24-hour cleaning cycle, the cooling water discharge exhibited a ...

A four-step guide to accurately calculating surface water discharge
Today, a wide range of government agencies, municipalities, utility companies, and private companies need to monitor water flow in rivers, streams, and canals for a variety of reasons ranging from predicting water availability and flood events to allocating water resources and planning for future development. At a high-level, these organizations are concerned with the water flow and discharge of ...

Talisman - produced water treatment to <30 ppm
Client: Talisman Buchan Alpha - UK Following successful trial work, CETCO supplied a single 48” CrudeSep® vessel skid to treat produced water for discharge overboard. Talisman then purchased a second 48” CrudeSep vessel skid to further reduce its overboard oil in water discharges in line with regulations. CETCO’s CrudeSep system treated approximately 12,000 bbls/d of produced water on the ...

Possible ways to improve sediment deposition in the Nemunas delta
The deposition of sediment in the inundated floodplains of rivers, particularly in their deltas, improves the water quality of the rivers themselves and of their receivers. It would be very useful if ways to increase the amount of sediment deposition could be identified. An investigation into a number of possibilities was carried out in the delta of the River Nemunas. Various factors can ...
