Treatment and Disposal of Air Pollution Control Residue
What is APCr? Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic operation of incinerators, modern ERF technology is now typically only applied to residual waste, i.e. municipal waste following...
Ballast water treatment on Alaskan coastline - Case Study
An Alaskan oil terminal had to deal with contaminated ballast water that needed to be collected and treated before discharge. They had a biological treatment process on site, but it was difficult to operate in the temperature and contaminant loading extremes the site experiences and they struggled to get it to work consistently. The plant is also required to treat spring snowmelt and rain that falls within the site boundaries, creating extremes of liquid temperatures and contaminant concentrations. QED ran...
Using Air Strippers for Off-gas Treatment - Case Study
Two pharmaceutical plants in Puerto Rico used large sequencing batch reactor (SBR) systems to treat their wastewater. The primary treatment was an aerobic bio breakdown of the waste. The were forced to change their treament process because of change in treatment regulations. The new regulations required them to treat off-gas that was coming from the SBRs. They were faced with installing a very large catalytic thermal oxidizer (CATOX) to treat the off-gas. They came up with the idea that if they could pretreat the...

Case study - Sludge digestion/thickening optimizes treatment
Overview: Big Park Domestic Wastewater Improvements District in Arizona had constructed a new 500,000 gallonsper day biological wastewater treatment system in 1997. As time passed, the aging plant was unable tokeep up with increasing demands. Challenge: In 2012, the District started working with Sunrise Engineering to find a solution that would work in theirexisting plant. Sunrise Engineering partnered with Aeration Industries International to upgrade theequalization basin, as well as the sludge digester/thicken...
