  • Odour Control at Pesticide Facilities: Eliminating volatile compounds

    Chemical formulation plants are susceptible to emissions of unpleasant and malodorous volatile compounds, a fact which makes the implementation of efficient odour control measures essential. North-western Spain is home to one of the country's oldest industrial sites for the manufacture of phytosanitary products, with some facilities located relatively close to populated areas. Recently, the ...

  • Ion Exchange Systems.

    When properly applied, ion exchange for concentrated ion recovery is by far the best available technology. Where effluent streams can be filtered and ions requiring different regenerants can be segregated, ion exchange is usually the most cost effective and least capital intensive solution. We provide 4 levels of integration to cover most applications and capital budgets. The variations in the ...


  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • Regenerative Thermal Oxidizers…What You Should Know.

    Within industry today, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new.  In response to Congressional guidelines passed in the 1970’s, a number of companies with VOC emissions have been operating air pollution control systems of one type or another for 25 years or more.  These guidelines have been revised and added to as the years ...

  • What makes an effective odor control cover system design?

    Background A common side effect of wastewater treatment processes is the unpleasant odor that can linger near the plant, annoying neighbors, who then complain. Often, the wastewater treatment plant was built many years ago in an isolated part of town.  Over the years, the town’s population grew until subdivisions were developed next to the treatment plant.   ...

  • 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 ...

  • What is Wastewater?

    What is wastewater? Wastewater, the waste discharge that first comes to mind in any discussion of stream pollution, is the discharge of domestic wastewater, which contains a large amount of organic waste. Industry also contribute substantial amounts of organic waste, some of which comes from vegetable and fruit packing; dairy processing; meat packing; tanning; processing of poultry, ...

  • Odor Control Advances at Composting Facility

    The Rockland County (New York) Cocomposting Facility began operations in February, 1999, processing biosolids from the five publicly owned treatment works (POTWs) in the county. The Rockland County Solid Waste Management Authority (RCSWMA) owns the facility, but contracted with Waste Management of New York to design, build and operate (DBO) the 110 wet tons/day agitated bin composting facility ...

  • Crossflow Membrane Filtration High-Purity Water Systems

    INTRODUCTION As the electronics industry continues to provide us with such products as high resolution television, notebook size portable computers and cars with automatic navigation systems, it becomes necessary to produce semiconductors with finer device geometries to allow for efficient placement of more circuits per a given area. This requires increased control of a semiconductor's material ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...
