  • Modelling study of liquid crystals orientation in the presence of corrosion potential

    The anchoring and orientation of liquid crystal (LC) molecules are influenced by several parameters. This paper presents theoretical work that aims to explain how surface changes and potential due to corrosion, affect the LC orientation and anchoring. This work is done with a view of enabling the design and development of a LC based corrosion ...

  • Higher corrosion resistance of old cast iron pipes installed for early stage of water supply network in Yokohama City

    The old gray cast iron for water supply pipes in Yokohama City which was made in the UK in 1887 is highly corrosion resistant. The corrosion behavior of the old gray cast iron in soils was studied. For comparison, a gray cast iron used for modern pipes, a spheroidal graphite cast iron, and a carbon steel were tested. The corrosion potentials and corrosion rates were measured. The corrosion ...

  • Challenges in addressing variability of lead in domestic plumbing

    Current data indicates that lead exposure is of concern even at low concentrations. Corrosion is an important problem in drinking water because it can affect public health due to leaching of lead or other metals into the drinking water. For this reason, a corrosion control program is an important measure to help mitigate exposure to lead in drinking water. The biggest challenge that remains in ...

  • Containment for Ground Water, Surface Water, And Leachate

    Containment measures are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards ...

  • Development of Pd-coated ceramic electrodes in hybrid sulphur cycle

    The Hybrid Sulphur (HyS) cycle has attracted much attention as a mass production process for hydrogen. It consists of an electrolysis step and a thermal decomposition one. In order to achieve high efficiency for hydrogen production and operational cost reduction, some developments in electrode materials with high corrosion resistance, high electrical conductivity and low anodic potential is a key ...

  • Evaluation of Compliance Strategies to Meet Stringent Effluent Copper Limits

    The objective of this evaluation was to determine the optimal means for the City of Puyallup, Washington to comply with stringent wastewater treatment plant effluent copper limits through bench and pilot testing of possible approaches. A source evaluation determined that corrosion of domestic and commercial plumbing was the primary source of copper in wastewater entering Puyallup’s Water ...

  • Evaluation of groundwater quality and assessment of scaling potential and corrosiveness of water supply networks, Iran

    The aim of this study was to determine the corrosion and scaling potential of water supply sources in a province in eastern Iran. In this cross-sectional study, 879 samples were taken to evaluate the water quality characteristics during 12 months (2013–2014). Five indices, Langelier, Ryznar, Puckorius, Larson–Skold, and Aggressiveness, were programmed in Microsoft Excel. The results ...

  • Model Testing Optimizes and Verifies Design of a 200-MGD Trench Wet Well for the Sugar Creek WWTP

    Charlotte-Mecklenburg Utilities (CMUD) and CDM are currently involved in the design of several treatment plant upgrades at the Sugar Creek wastewater treatment plant (WWTP) in Charlotte, North Carolina. Implementation of this project, which includes a 200-million-gallonper- day (mgd) screenings and influent pump station with dual self-cleaning trench-type wet wells, will provide CMUD with the ...

  • Kressview springs condominium, Cambridge, Ont., Canada - Case Study

    Unstable soils, steep embankments, limited right-of-way and site access and other adverse site conditions can make design and construction decisions difficult and the outcome costly. The developer of the Kressview Springs condominium project in Cambridge, Ontario, Canada was faced with a series of these unique construction challenges during construction in the Winter of 1989. Situated on the side ...
