  • Calculation of energy recovery and greenhouse gas emission reduction from palm oil mill effluent treatment by an anaerobic granular-sludge process

    Conventional aerobic and low-rate anaerobic processes such as pond and open-tank systems have been widely used in wastewater treatment. In order to improve treatment efficacy and to avoid greenhouse gas emissions, conventional treatment can be upgraded to a high performance anaerobic granular-sludge system. The anaerobic granular-sludge systems are designed to capture the biogas produced, ...

  • Sensitivity of urban dispersion calculations to urban meteorology (COST 715)

    Generally, the worst air pollution occurs in cities. This paper describes the COST 715 programme, which is a European activity supporting scientific exchange and networks on 'meteorology applied to urban air pollution problems'. For urban pollution assessments one needs the input of pollution near the ground, 'averaged' over an area containing a mixture of houses, gardens, streets, etc. The ...

  • Dispersion modeling— New downwash calculations change the playing field

    For many people, the terms “stack height” and “dispersion model” do not ring a bell. Others grapple with these terms as they can be challenging factors in the process of obtaining an air construction permit. Have you ever constructed a stack at a specific height due to EPA guidelines and regulations surrounding Good Engineering Practice (GEP) as it relates to air ...

  • Tackling remediation emissions

    Organisations commissioning regeneration projects now have the option to substantially reduce the carbon emissions associated with any remediation project, while offsetting the remaining carbon impact of these works, says Joe Teer, operations director of QDS. QDS introduced a carbon neutral remediation (CNR) service earlier this year triggered at this particular time by the fact ...


  • A constant eye on emissions

    Due to increasingly rigorous requirements for regulatory and permit compliance, organisations are seeking more from all compliance support systems. The ability to expand systems to encompass new, or migrate existing, regulatory calculations used to monitor environmental performance is vital. Planning strategically for a scalable and sustainable system has been shown to reduce overall compliance ...
