  • Arsenic Removal

    The Arsenic Removal ProcessArsenic, a naturally occurring element, is found throughout the environment; for most people, food is the major source of exposure. Acute (short-term) high-level inhalation exposure to arsenic dust or fumes has resulted in gastrointestinal effects (nausea, diarrhea, abdominal pain); central and peripheral nervous system disorders have occurred in workers acutely ...


  • Removal of cyanide from liquid wastes by modified clinoptilolite

    This paper describes the preparation and evaluation of various cationic forms of clinoptilolite for removal of cyanide from aqueous solutions. The cobalt form of the zeolite showed the highest uptake of 1.95 meq of cyanide per gram of zeolite, whereas the uptake of natural forms is 0.070 meq g-1. The kinetics of cyanide desorption into solutions with different ionic strength were studied. ...

  • Dynamic restructuring of waste removal in decentral plants

    The mechanical and biological treatment of residual waste meets the requirements for the production of defined material flows out of nonspecific waste. The specific material flows can reach the quality demands of the industry by wet screening, when beforehand the result of composting is a far-reaching biological stabilisation of the residual waste. Three fractions can be separated: recyclable and ...

  • Removal of hexavalent chromium from aqueous solution by lignocellulosic solid wastes

    The batch removal of Cr(VI) from aqueous solution using lignocellulosic solid wastes such as sawdust and pine leaves under different experimental conditions was investigated in this study. The influence of pH, temperature, contact time, initial concentration of Cr(VI) and particle size on the chromium removal was investigated. Adsorption of Cr(VI) is highly pH-dependent and the results indicate ...

  • Using ‘TransMembraneChemiSorption’ (TMCS) for Ammonia Removal from Industrial Waste Waters

    Dissolved gases like NH3, H2S or NOx in waste water lead to contamination in the sewage system and high treatment costs for municipal waste water treatment plants. This translates into high penalty fees that are paid by the company discharging these contaminates into the sewage stream. In many cases a membranebased water treatment system can be justified because of a favorable pay back time. ...

  • Go for the Cheap but Secure Lab Waste Removal and Recycling Plan!

    In the last couple of decades, the number of laboratories that are part of universities, hospitals and other facilities is growing and this is definitely good news. Thanks to these labs we can improve our quality of life. However, during the process of research and use of these labs, specialists who work there create lab waste. This waste can be potentially dangerous and this is the reason why ...

  • CERCLA remedial and removal actions at historic waste disposal areas.

    Apache Nitrogen Products, Inc. (ANP) has operated a nitrogen-based fertilizer and explosives manufacturing facility in rural Cochise County since 1921. Using a feedstock of anhydrous ammonia, current manufacturing processes produce nitric acid, solid and liquid ammonium nitrate, and various ammonium nitrate-based fertilizer products for regional mining and agricultural markets. Historically, ...

  • Removal of viruses and indicators by anaerobic membrane bioreactor treating animal waste

    Appropriate treatment of agricultural waste is necessary for the protection of public health in rural areas because land-applied animal manure may transmit zoonotic disease. In this study, we evaluated the potential of using a pilot anaerobic membrane bioreactor (AnMBR) to treat agricultural waste. The AnMBR system, following a conventional complete mix anaerobic digester (CMAD), achieved high ...

  • Jar Testing for Metals Removal

    Using the chart below, find the metal(s) of concern. Determine the best pH range for maximum insolubility for the metal(s). If there is a combination of metals, then concentrate on the metal with the highest concentration and adjust the pH to this point. Determining the Optimum pH for combined metals: Typically facilities have 2, 3 or more different metals in their waste stream. To determine the ...

  • Adsorptive removal of As(III) from aqueous solution by waste litchi pericarps

    The present study investigated the removal of arsenite anions (AsO33−, referred to as As(III)) from aqueous solutions by waste litchi pericarps (LPs). Influential factors such as the adsorbent dose, contact time, solution pH, and initial As(III) concentration were investigated. The optimum conditions for As(III) adsorption by the LPs occurred at a contact time of 60 min, adsorbent dose ...

  • Removal of Radioactive Effluent Waste from Uranium Enrichments Plants

    In an effort to reduce greenhouse emissions many nations and multi-national corporations are once again focusing on the development of safe radioactive sources for energy generation. After a hiatus of some 20 years commercial nuclear power plants are being developed globally to satisfy increasing global energy demands. Whether for generation of electrical power or in the production of fission ...

  • Preparation of cationic waste paper and its application in poisonous dye removal

    Cationic paper was prepared by reaction of paper with 2,3-epoxypropyltrimethylammonium chloride in aqueous suspension, and tested as low-cost adsorbent for wastewater treatment. The experimental results revealed that anionic dyes (Acid Orange 7, Acid Red 18, and Acid Blue 92) were adsorbed on the cationic paper nicely. The maximum amount of dye Acid Orange 7 adsorbed on cationic paper was 337.2 ...

  • Use of various agricultural wastes for the removal of heavy metal ions

    There is a need to develop innovative and alternative technologies that can remove toxic heavy metal pollutants from wastewater. In this study, two agricultural residues, cotton stalks and apricot seeds, were used to adsorb copper and lead in solutions. Sorption capacities of agricultural wastes were significantly affected by solution pH, adsorbent mass and adsorbent particle size. The adsorption ...

  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • CH#835 - Grease Removal

    The problem of degrading 6,000+ ft of grease daily has an easier solution than thought at the 27 MGD a Massachusetts Waste Water Treatment Plant. 'At one time, the plant had more grease in its scum pits than it could handle,' said an  engineer . 'Worse yet, there was nowhere to put it. Local landfills stopped accepting greasy solids.' Now the plants grease problem has been virtually solved. ...
