  • Managing Ponds for BOD Reduction and Odor Control

    A large number of food processors utilize ponds to treat their wastewater. Most of the time these ponds are aerobic in which they use oxygen to degrade the wastewater biological oxygen demand (BOD). Fruit and vegetables contain a high amount of simple sugars and other organic compounds that when exposed to water are released into the water stream. These organic compounds require oxygen to degrade ...

  • On-site infiltration of road runoff using pervious pavements with subjacent infiltration trenches as source control strategy

    The focus in this work was on subsoil infiltration of stormwater from parking lots. With regard to operation, reduced infiltration performance due to clogging and pollutants in seepage, which may contribute to contaminate groundwater, are of interest. The experimental investigation covered a pervious pavement with a subjacent infiltration trench draining an impervious area of 2 ha. In order to ...

  • Influence and control of coal facies on physical properties of the coal reservoirs in Western Guizhou and Eastern Yunnan, China

    Western Guizhou and Eastern Yunnan have abundant coal resources, and they are considered as the most prospective areas for coalbed methane (CBM) development in Southern China. To explore the potential of CBM production in these areas, this paper identifies the plane distribution of coal facies, and analyses its control on the physical properties of coal reservoirs. Four types of coal facies ...

  • Natural Gas Compressor

    Reciprocating engines come in all sizes, from a tiny, 10cc piston engine that powers a model airplane, to the massive Wartsila RTA 96-C, with each of its 14 cylinders displacing 1,820,000 cc. While our borescopes won’t be much help on the model airplane engine, if you work on any medium or large size reciprocating engine, the chances are good that we have a video borescope that can make ...

  • SVFlux and SVSlope in UTSA Senior Project - Bell County Earthen Dam

    General This article presents a recent project performed by undergraduate students at The University of Texas at San Antonio. Their project is the culmination their degrees in a capstone class. The objective of the class was to present an opportunity to apply design skills to execution of an open-ended integrated civil engineering design project, including field and laboratory ...


  • Mass balance of Cadmium in two contrasting oak forest ecosystems

    The mass balance of cadmium in forest ecosystems was parameterized. Soil pH is the main variable controlling retention of Cd in the soil and, hence, determines whether Cd is leached from the system or not. However the extent to which root uptake and biomass accumulation of Cd, or the return of Cd to the soil as internal cycling, influences forest Cd balances is unknown. Also unknown is whether ...

  • Supergro is the ideal solution for developer’s erosions problems

    BACKGROUND Lakeside of Oakdale is a residential development located in northeastern Oklahoma City. This development centers around a 23-acre recreational lake with ample opportunities for soil erosion. The developer wanted to make sure that the slopes in the development and especially around the lake's perimeter were stabilized and vegetated as the lake filled with water and construction of ...

  • Case study - Polyphosphates for in situ uranium immobilization

    INFORMATION Carus Corporation has a long history of developing and providing a variety of permanganate products for chemical oxidation applications. Carus is also a leading provider of phosphate products for sequestration and corrosion control. Phosphates are widely used as water treatment chemicals (dry or liquid solutions) to correct problems resulting from inorganic groundwater ...

  • High sensitivity CO2 monitor for CO2 geological sequestration efficiency monitoring

    Canadian prosperity is currently linked to revenue generated from processes that produce large volumes of greenhouse gasses as a by-product. Under evidence that the human fingerprint on our planet is in direct correlation to global climate change, the monitoring and control of greenhouse gas emissions has become a subject of recent focus among many sciences. Recently, legislation has been imposed ...

  • Full Scale Treatment of Slaughter House and Meat Packing Waste at Jennie-O Turkey Store, Barron, Wisconsin

    ABSTRACTJennie-O Turkey Store owns and operates a 0.057 m3/sec (1.3 MGD) treatment plant for treating wastewater from the slaughter of 26,000 turkeys per day. In 2000, Jennie-O Turkey Store was required by the Wisconsin Department of Natural Resources (WDNR) to remove phosphorous below 1 mg/l. The existing lagoon system with seepage cell was not removing phosphorous cost effectively and odors ...

  • Lake Lenexa Stormwater Management Project

    Using cutting-edge technologies to significantly upgrade wastewater treatment in coastal areas, B&V Water helped Southern Water keep pace with the requirements of new UK and EU legislation. B&V Water took an innovative approach to turn stormwater management into a recreational park in Lenexa, Kansas, and offer communities globally a successful integrated stormwater strategy. As ...

  • In-Situ thermal treatment of MGP waste and creosote

    Abstract: Remediation of coal tar at former Manufactured Gas Plant (MGP) sites, and creosote associated with wood preservative sites is challenging due to the viscous nature of the dense non-aqueous phase liquid (DNAPL) and the modest solubility and vapor pressure of the contaminants of concern (COCs). DNAPL seepage into surface water bodies, as well as groundwater plumes formed by the most ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...


  • Use of Mathematical Models to Evaluate Management Options for Reducing PCB Bioaccumulation by Fish in Two Streams at the Neal`s Landfill Site, Bloomington, IN

    ABSTRACTNeal’s Landfill received PCB-containing wastes that originated from a Westinghouse Plant in Bloomington, IN. PCBs have been transported to the groundwater beneath the site and into two nearby streams: Conard’s Branch and Richland Creek, and consequently, PCBs have impacted the water, sediments, and fish of these streams. Remedial actions conducted at the site have included removal of ...

  • Excavation, Retrieval, and Off-Site Disposal

    Introduction: Contaminated material is removed and transported to permitted off-site treatment and/or disposal facilities. Some pretreatment of the contaminated media usually is required in order to meet land disposal restrictions. Confined disposal facilities (CDFs) are engineered structure enclosed by dikes and designed to retain dredged materials. A CDF may have a large cell for ...
