  • Testing VOC Evaporation Losses from Floating Roof Tank Turnovers

    Air emissions from floating roof tanks have been well characterized and documented by the U.S. Environmental Protection Agency (EPA). The estimation methods have been revised and updated throughout the years. However, an unusual aspect of air emissions from tanks with a floating roof during a tank turnover has not been addressed. Petroleum storage tank floating roofs are landed on tank legs and ...

  • Novel method for sludge blanket measurements

    The most widely used methods for sludge blanket measurements are based on acoustic or optic principles. In operation, both methods are expensive and often maintenance-intensive. Therefore a novel, reliable and simple method for sludge blanket measurement is proposed. It is based on the differential pressure measurement in the sludge zone compared with the differential pressure in the clear water ...

  • Wastewater sterilization (purification): completely new method “vortex layer machine”

    The purification and safe disposal (neutralization) of industrial waste water effluents represent a very important ecological problem. The principal problem or requirement involves reducing the concentration of harmful impurities to concentration levels below their maximum allowable concentration limits. In fulfilling this requirement the amount of fresh water consumption needed to maintain the ...

  • Crude oil tank profiling case study

    A little while ago we were approached by Cyprus Petroleum Refining Ltd, the largest Cypriot refining company to undertake the sludge profiling of eight crude oil tanks. The company sent two of its most experienced team members to carry out the work. Over a two week period in the middle of summer the team landed the floating roofs of the eight tanks and commenced the sludge profiling using a tried ...

  • Innovations in Bench Testing of Waste waters

    Wastewater management in developing countries throughout the world is in a state of crisis. It is estimated that 2.6 billion people worldwide live without adequate sanitation. Resources are scarce, previous management systems have failed, and traditional techniques and solutions are not immediate enough, too expensive, or simply inefficient. Discussion with regards to OI Analytics Instrumentation ...

    GUEST BLOG: 48-hour tank lining corrosion repair, thanks to SPI’s fast curing Polyshield HT-100F UB In this post, we focus on a tank lining corrosion repair that’s recently been completed by our 2015 Global Distributor of the Year, SPI Performance Coatings Ltd, of Wiltshire UK. This particular project involved a ...

  • Case study - Performance testing PAHs in soil

    These case studies highlight Sitelab’s accuracy from customers who have used the UVF-3100D for testing Target PAHs. This test correlates well to U.S. EPA Method 8270 or similar GC methods, which includes a list of 16 or more compounds. The analyzer is fitted with special optical filters sensitive to this same group of hydrocarbons. Examples of UVF-3100D testing Polycyclic Aromatic ...

  • Pilot-Scale Biofilter Test for Treating Zimpro Odors

    The thermal sludge conditioning process of U.S. Filter/Zimpro Corporation, Rothschild, Wisconsin (Zimpro process) is primarily used to improve dewatering characteristics of the waste sludge. The process entails a partial breakdown through oxidation and hydrolysis of complex, high molecular weight organic compounds, such as, proteins, fibers, carbohydrates, and fats. The partial breakdown of ...

  • Case study - EDRO in soil at petroleum tank farm site

    Environmental engineers needed quick and accurate screening analysis on a tank farm contaminated with a subsurface plume of fuel oil. Sitelab's EDRO test was performed to delineate the vertical extent of contamination. A drill rig was used to collect samples from the surface down to twenty feet at different locations throughout the property. They needed to quantify the size of the NAPL plume in ...

  • Enhancement of settling tank capacity using a new type of tube settler

    The effectiveness of a newly developed lamellar settler was confirmed by onsite experiments. The device had inclined parallel plates arranged in a vertical direction in a settling tank. This vertical arrangement method enables many more plates to be set compared to the conventional horizontal arrangement. As an original and distinctive innovation, both the right and left edges of the plates were ...

  • Development of an American Society of Testing and Materials (ASTM) Stationary Skimmer Test Protocol - Phase 2 Development

    Abastract The development of a simple and inexpensive standard test protocol to determine a realistic nameplate capacity for oil skimmers is underway within the American Society of Testing and Materials (ASTM); however, there are differing opinions on how these tests should be conducted. A significant point of contention has been whether to test skimmers using oil only or using an oil layer ...

  • Double Duty Scrubber for TDI Fumes A case-history description of a relatively uncomplicated but effective method for handling large runaway emissions of TDI and solvent vapors.

    NKI (B. V. Nederlandse Kleurstofindustrie, a subsidiary of Morton-Thiokol, Inc. U.S .A.), and one of the major industrial firms in the Netherlands, had a problem with extremely toxic TDI (toluene di-isocyanate) emissions from one of their processes . On a batch basis in different reactors, the largest being 6.5 m cubed(1717 U.S . gallons), a solution polymerization of TDI with polyols in a ...

  • Evaluating the effects of septic tank on shallow wells in Iba housing estate, Ojo LGA, Lagos

    Water samples from 30 shallow wells were measured for depth, depth to water table, and distance to septic tank. In situ parameters including electrical conductivity, pH, total dissolved solids, and temperature were measured using portable meters. Chemical parameters including salinity, chloride, calcium, alkalinity and total hardness were determined using titrimetry method. Sulphate and nitrate ...

  • The extension of EPANET source code to simulate unsteady flow in water distribution networks with variable head tanks

    This paper describes the modifications applied to EPANET, a public-domain water distribution system modelling software package, that does not correctly compute the hydraulics of a water distribution network (WDN) with variable tank heads in (slow) unsteady flow conditions. Firstly the methodology adopted to extend the Global Gradient Algorithm (GGA) implemented in the original EPANET source ...

  • Toxicity of crude oil chemically dispersed in a wave tank to embryos of Atlantic herring (Clupea harengus)

    Tests of crude oil toxicity to fish are often chronic, exposing embryos from fertilization to hatch to oil solutions prepared using standard mixing procedures. However, during oil spills, fish are not often exposed for long periods and the dynamic nature of the ocean is not easily replicated in the lab. Our objective was to determine if brief exposures of Atlantic herring (Clupea harengus) ...

  • Filterability assessment in membrane bioreactors using an in-situ filtration test cell

    A new method for the assessment of the filterability in membrane bioreactors was tested for five months in four MBR units in Berlin. The new method BFM (Berlin Filtration Method) for filterability assessment uses a small membrane filtration test cell which can be submerged directly in the biological tanks to determine the filterability of the activated sludge in-situ. The test cell contains an ...
