This burnt lime is particularly suitable ...

  • Case study - Petroleum remediation systems

    Overview A major oil company was looking for a way to stay ahead of EPA regulations for soil vapor extraction of BTEX and the subsequent treatment of these gases. They were looking for one company that could offer competitive pricing, local support service, and the application expertise to provide 50 remediation units throughout the ...

  • Case study - Cheese manufacturer gets aeration upgrade

    Largest Cheese Manufacturer in the UK Gets Aeration Upgrade Dairy Crest Davidstow Creamery in Camelford is the largest cheddar cheese manufacturer in the UK. The process of collecting and processing milk is a 24/7 operation, generating effluent round the clock and needing to be treated and disposed of continuously. Effluent from the cheese-making process contains high fat content and ...

  • Case study - Built for generations

    When building a wastewater treatment facility in 1984 officials in a Wisconsin village decided on an oxidation ditch design and chose Aire-O2®Aspirator aerators based on their flexibility and energy efficiency. Today, several of those aerators are still in use and the treatment facility operates at even more ...

  • A perfect pair: SBR designs & advanced aeration technology

    Conventional sequencing batch reactors (SBRs) that utilize diffused-air networks have existed in the U.S. for about three decades now. The reliability of controls and instrumentation has significantly improved in the last 10 to 15 years, and as a result, SBR plant designs are becoming more widely accepted. The attractiveness of their compact layout and ease of operation has also helped increase ...

  • Case study - Aeration ditch upgrade exceeds expectations

    Triton Process Aerators Meets Future Nitrogen Permit Regulations When the a Pennsylvania Sewer Authority was researching methods to improve the dissolved oxygen levels in its wastewater treatment plant’s oxidation ditches in 2001, they decided to totally replace its aging brush rotor system. They replaced the rotors with the  ...

  • Efficient aeration system boosts energy savings

    A new efficient aeration system saves the Ontario, Ore., wastewater treatment facility $47,000 annually in energy costs. Besides giving this community a financial boost, the new system netted additional equipment cost savings by cutting aeration horsepower by more than half at the plant. The environmentally conscious city, located in the Oregon/Idaho border area, is meeting all of its effluent ...

  • Minimizing Operating Costs in VOC Abatement Equipment

    Untitled Document As governmental regulations of environmental emissions become more restrictive, the average concentration of Volatile Organic Compounds (VOC's) has decreased as more ...

  • Case study - SBR keeps noise, energy & capital costs low

    Pennsylvania is home to one of the first Argos® SBR plants to utilize a surface mounted process aerator/mixer, which is a significant improvement over the traditional diffused air network designs. The new layout offers substantial capital investment savings as well as significant reductions in ...

  • Case study - DO control maximizes oxidation ditch treatment efficiency

    Process control is key to maximizing wastewater treatment efficiency while minimizing operating costs. Implementing the right process control system in conjunction with the right equipment can save money on electrical costs and equipment maintenance. The wastewater plant for the city of Dawson, MN, uses a  ...

  • Aire-O2 Triton Solves Bulking Problem

    The Dubai Investments Park (DIP) wastewater treatment plant (WWTP) is located about 20 miles south of the Burj Khalifa – the world’s tallest building. The oxidation ditch activated sludge plant recently found itself strained by filamentous sludge bulking likely caused by high organic loads, high summer temperatures and inevitable low dissolved ...

  • Triton solves bulk of the problem case study

    The Dubai Investments Park (DIP) wastewater treatment plant (WWTP) is located about 20 miles south of the Burj Khalifa – the world’s tallest building. The oxidation ditch activated sludge plant recently found itself strained by filamentous sludge bulking likely caused by high organic loads, high summer temperatures and inevitable low dissolved oxygen. The problem was easily ...

  • Case study - Oxidation ditch expansion comes with host of benefits

    This wastewater treatment plant located in Texas was originally designed in 2000 but within several years, the city needed to double the treatment capacities of the facility. The wastewater treatment plant was designed with a plant capacity of 1.5 MGD utilizing a single ditch with the extended aeration activated sludge process for secondary treatment to facilitate removal of ...

  • Air Pollution Control in the Printing and Web Coating Industries

    For many U.S. companies in the printing and web coating business, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new.  In these industries, depending upon their location, companies have been installing APCS since the early 1970's.  However, for some companies the clock is still ticking regarding their compliance with local, state and federal ...
