  • Scrubber Removes Grease and Particulates from Air Exhaust

    Operating Issue A food-industry leader in Alabama operates several pork-sausage cookers that exhaust over 4,000 ACFM of moisture and pork grease. The operator installed Electrostatic Precipitators (ESPs) to treat the exhaust but these systems performed poorly and generated high maintenance and operating costs. Additionally, these systems were antiquated and required significant capital ...

  • Why is Energy-from-Waste slow to catch on in the U.S.?

    Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more ...

  • How to choose the best Industrial Water Filtration System for mining applications

    Over the course of the past few decades concern for the environment has brought about a large number of new regulations concerning the use of water in mining operations. These include how it is accessed, and how it is treated, using industrial water filtration to ensure all ...

  • How industrial water filtration can improve efficiency and save you money

    Over the course of the past couple of decades, industrial water filtration has become one of the most important considerations for the average manufacturing facility in North America. These concerns have only increased as water supplies have dwindled and wastewater contamination standards have become more stringent. All of this has led to the need to choose the right industrial water filters and ...

  • The Importance of Dewatering

    With spring comes two things: the onset of construction season for most of our country and rain- lots and lots of rain. The unpredictability of storms and the amount of rainfall is all a guessing game.  Jobsites flood, work stalls and projects get delayed. Rain makes it hard to keep dry and on-schedule. What’s the solution? Dewatering is a technique used to control ...

  • How Do You Choose the Best Reverse Osmosis and Nanofiltration Membrane System for an Industrial Facility?

    As global demands for clean water increase, more and more industrial facilities are looking toward membrane filtration solutions, such as reverse osmosis (RO) and nanofiltration (NF), to help manage intake, process, and waste water treatment. Using membrane filtration can help your facility reuse wastewater and virtually eliminate discharge fees, and depending on the industry or required use, it ...

  • Oil Recycling - Case Study

    The problem: Waste oil recycling contributes very much to climate protection through (CO2) energy saving. Compared to the production of base oil the re-refining of waste oil uses 34 % less resources. In the sixties the German government was subsidising the re-refining of waste oil. Because of that the use of waste oil as a fuel was neglected. The used oil re-refining is the ...

  • Keeping APCr out of Landfill

    The CIWM have recently featured an article by our very own Dr David Deegan in the latest edition of their magazine. The article explains why Tetronics International were unhappy to be informed recently that Defra ministers had taken the decision not to remove the ...

  • Confirming Natural Attenuation Processes at a Coastal Site - Case Study

    Past waste disposal practices at a California coastal site resulted in a groundwater plume containing CVOCs (mainly chlorinated ethenes [CEs] and 1,1-dichloroethane) migrating offshore towards a marine harbor. CVOCs are present in the sediment porewater adjacent to the shoreline, but concentrations decreased significantly between 2000 and 2015, and NA in the marine sediments was suspected. To ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • A solution to fracturing water supply and disposal issues

    “Water, water, everywhere, Nor any drop to drink.” –The Rime of the Ancient Mariner, Samuel Taylor Coleridge Many topics of conversation among oil and gas industry professionals are predictable – oil price trends, the “great shift change” imperiling the available workforce, and production quotas and caps from OPEC. Yet one pressing topic among those developing ...

  • Ethylene Removal: Reduce Wasting Food

    ETHYLENE REMOVAL: Reduction of fruit and vegetable waste throughout the distribution chain  Approximately one-third of the worldwide production of foods for human consumption is lost or squandered, equivalent to some 1,300 million tonnes each year.    This means that enormous ...

  • Mercury Removal

    The Adventus Mercury Removal AdvantageResponsible environmental experts in the academic, business and regulatory communities are increasingly more worried about the high levels of mercury contamination affecting many parts of the world. The international community is focusing their attention on this growing problem and EHC-M will clearly help, as it is perfectly suited for treating environments ...


  • 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 ...


  • 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 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. ...

  • Waste agricultural fibres highly effective removing water pollution in developing countries

    Discharging different kinds of wastewater and polluted waters such as domestic, industrial and agricultural wastewaters into environment, especially to surface water, can cause heavy pollution of this body sources. With regard to increasing effluent discharge standards to the environment, high considerations should be made when selecting proper treatment processes. Any of chemical, biological and ...

  • Application of silica gel factory waste for methyl orange dye removal

    The silica gel waste (SGW), after its collection from a local factory (at Kolkata, India), was modified with cationic surfactant and was utilised as an adsorbing media for the removal of methyl orange dye from aquatic environment. In batch mode, the effect of different dissolved salts, solution pH, and surfactant surface coverage on SGW were studied. Presence of electrolyte and solution pH was ...

  • Biological nitrate removal using waste-derived extracts as sole carbon source

    Waste-derived multicomponent extracts were investigated as carbon source for biological nitrate removal. Aerobic and anaerobic sludge from a municipal wastewater treatment plant and leachate from an anaerobic digester treating food waste were studied. Alkaline-heat treatment was used for sludge solubilisation. More than 90% carbon was recovered at pH 10–11. The extracts contain very high ...

  • Removal of arsenic from an aqueous solution by pretreated waste tea fungal biomass

    Arsenic exists in natural waters both in inorganic and organic forms. The inorganic form of arsenic is more toxic compared to its organic form. Inorganic arsenic is the predominant form in contaminated groundwater. Arsenic exists in two,oxidation states: arsenite, As (III) and arsenate, As (V) (Pokhrel and Viraraghavan, 2006). It is introduced in the aqueous system through geochemical reactions ...
