UV Light Treatment for HVAC Systems
Ultraviolet (UV) light can be applied to support numerous applications in a broad range of industries. In commercial paint spray booths and label manufacturing plants, UV lamps are used to streamline paint jobs and the printing of logos. Outside of such practices, the light source may also be utilized to eradicate harmful, disease-causing bacteria. Systems that rely on the light’s ability to disinfect the surrounding environment (surface and air) are mostly found in food processing plants and medical...
Waste Water Batch Treatment System
Industrial Wastewater Treatment Batch Treatment Systems (BTS) are intended for lower daily volumes of wastewater typically less than 10,000 gallons per day and designed to “batch” treat wastewater from start to finish at one time. In a batch treatment system, a volume of wastewater is gathered, treated by chemical / physical / biological means, and discharged. Storage Tanks accumulate waste often segregated as acid, alkaline, cyanide and hexavalent chrome-bearing which is transferred to a single...
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...
