  • ALBANISA Oil Spill Equipment Setup - Case Study

    As a part of the Bolivarian Alliance for the People of Our America (acronym in Spanish: ALBA), Nicaragua has received funds to build a new oil hub in the Caribbean. The hub will be available for oil companies in order to store their products before reaching its final destination. By doing that the profit will be increased as the costs for transportion is reduced. The updated environmental ...

  • MSW Management: Safely Countering the Rise of Landfill Odors

    One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints. In fact, compared to other industrial applications such as wastewater treatment and asphalt ...

  • Importance of Inspecting Reservoirs

    Inspecting Reservoirs – what is the importance of them, why they are inspected, and how ROVs help pave the way for low-cost, regular maintenance. What is a Reservoir? Deriving from the French word réservoir meaning “storehouse,” a reservoir is exactly that – a storage place for water. More often than not, these bodies of water are ...

  • Flow Rate Measurement in Full Pipes Using the Transit Time Method

    Particularly in large diameters the relevance of water volume measurement is growing. The challenge with cooling water or fresh water processes is to generate accurate flow recordings or to document and to control individual consumptions and withdrawal quantities. Flow detection, however, particularly in large diameters is highly demanding. In such cases the transit time measurement thanks to its ...

  • Compliance Trends in 2017: what to expect, how to prepare

    Looking back on 2016, it was without doubt a year of political upheaval and increased scrutiny on the environmental, social and human rights implications of government regulations, corporate practices and consumer habits. In 2017, these changes will fuel additional compliance considerations for corporate supply chains around the world. While the future is anything but certain, our regulatory ...

  • Biosolids ban struck down

    In 1994, Los Angeles County Sanitation Districts (LACSD) bought a 4,700-acre farm (called Green Acres Farm) in southwest Kern County for the purpose of land applying biosolids from its 11 wastewater treatment plants. LACSD land applied 800 wet tons/day at this site for several years. In 2006, Kern County voters passed Measure E on the ballot with 83 percent approval. This measure banned ...

  • 10 Reasons why you should continuously monitor low temperature and liquid chemical sterilants for worker safety

    1. Sterilant chemicals are highly toxic Low temperature and liquid chemical sterilants are designed to kill all microorganisms including resistant spores and if they were not toxic, they would not be effective in sufficiently high concentration to destroy all microbial life including the chemically resistant sporicidal forms of certain ...

  • Conductivity Theory and Measurement

    Electrical conductivity is a measure of the ability of a solution to cany* a current. Current flow in liquids differs from mat in metal conductors in that electrons cannot flow freely, but must be carried by ions. Ions are formed when a solid such as salt is dissolved in a liquid to form electrical components having opposite electrical charges. For example, sodium chloride separates to form Na" ...

  • A comprehensive review of conduction-controlled rewetting: theoretical models and analyses

    This review deals with conduction-controlled rewetting analysis for water-cooled nuclear reactors following a hypothetical Loss-of-Coolant Accident (LOCA). The first part of the survey deals with analytical solutions for various rewetting models. This contains the solution for one- and two-dimensional models, rewetting models with and without precursory cooling, rewetting models for two- and ...

  • Conducting core-sheath polyurethane-PEDOT nanofibres for conducting polymer actuator

    Conducting core-sheath nanofibres were prepared by the vapour-phase polymerisation of poly(3,4-ethylenedioxy thiophene) (PEDOT) on electrospun polyurethane (PU) nanofibres both with and without incorporating graphene nanoplatelets (GNPs) as the core part. The morphology, mechanical properties, electrical conductivity, and electroactive actuation of the core-sheath nanofibres were investigated. ...

  • Quality Assurance Guidance for Conducting Brownfields Site Assessments

    Executive Summary Many sites across the nation once used for industrial and commercial purposes are now abandoned or under-used. Some of these sites — often referred to as “Brownfields”— are contaminated; others are perceived or suspected to be contaminated. In 1993, the Environmental Protection Agency (EPA) created the Brownfields Economic Redevelopment Initiative to empower States, Tribes, ...

  • CProb: a computational tool for conducting conditional probability analysis

    Conditional probability is the probability of observing one event given that another event has occurred. In an environmental context, conditional probability helps to assess the association between an environmental contaminant (i.e., the stressor) and the ecological condition of a resource (i.e., the response). These analyses, when combined with controlled experiments and other methodologies, ...

  • Pure water pH measurement in low conductivity samples

    Normally, pH measurements are made in water with 1,000 to 10,000 uS/cm conductivity. The conductivity conies from dissolved solids, typically, salts plus net acid or base which explains the exhibited pH. These dissolved substances are in the solution in ion form, which makes such solutions conducting. With 1,000 uS/cm conductivity of mobile ions pH electrodes have a good circuit and give fast, ...

  • Conductivity Measurement in high purity water samples below 10 microsiems/cm

    High Purity Water Resistivity/ Conductivity Measurement Ultra-Pure Water without any chemical impurities will still have a conductivity because of the presence of H* and OH" ions due to the self-ionization of water. Ultra-pure water has a conductivity of 0.055 HSiemens'cm or a resistivity of 18.18 mQ-cm at 25 °C. In order to know the conductivity or resistivity of ultra-pure water it is ...

  • Effect of urban waste compost application on soil near-saturated hydraulic conductivity

    Received for publication February 22, 2008. Compost application tends to increase soil fertility and is likely to modify soil hydrodynamic properties by acting on soil structural porosity. Two composts, a municipal solid waste compost (MSW) and a co-compost of green wastes and sewage sludge (SGW), have been applied every other year for 6 yr to cultivated plots located on a silt loam soil in the ...

  • A voyage on the seven c`s - phase II common cause correction of a condenser`s conduct & condensate chemistry
