Wastewater treatment plants ‘produce’ a cleaned water stream and a dewatered sewage sludge product. To dispose of the sludge, many wastewater treatment facilities employ a sewage sludge incinerator (SSI). The types of SSIs used at wastewater treatment facilities include fluidized bed incinerators and multiple hearth furnaces. USEPA regulates air pollutant emissions from SSIs at wastewater […]
With electric vehicles steadily gaining in popularity, the EV battery industry is growing to meet the demand for vehicles. As most electric cars currently use lithium-ion batteries, the need to control process emissions has become extremely important. The lithium-ion battery production process commonly includes a coating process with subsequent dryers that can emit certain volatile […]
APC will be exhibiting at the ISRI2022 Convention and Exposition, March 21-24, 2022, in Las Vegas. This exposition, which hosts the largest concentration of recycling industry equipment and service providers in the world, is returning in person for the first time in two years. The event will feature over 250 vendors covering every facet of […]
Increasing concern for sustainability and the environment has led to growing focus on the recycling of our planet’s resources. In some cases, the recycling process itself can create new pollution problems, which require effective solutions. As a leading comprehensive solution provider to the scrap metal recycling industry, WENDT Corp. recognized the need for an air […]
APC Technologies (APC) installed multiple Ultra High-Efficiency Filter (UHF®) systems at a large asphalt terminal located in Western Canada. The air pollution control systems were installed to achieve two objectives: Greatly reduce hydrogen sulfide (H2S) concentrations in the breathing zones of operators, which were at unsafe levels; and Provide oil mist control, particulate control, and […]
Flexible packaging extruder and other process lines commonly emit very fine, white smoke from die and extruder exhaust points, with emissions from vacuum pumps at times as well. Such extruder smoke emissions can build up to potentially unhealthy levels inside the plant if not exhausted outside the plant. If the extruder smoke is simply exhausted […]
Commercial cannabis growing, harvesting, drying and extraction operations all release odors and volatile organic compounds (VOCs) that can be regulated by local authorities and/or considered a nuisance by employees and/or neighbors. At times, Owners need to take action and install cannabis a VOC control or odor control system. An earlier blog (see Cannabis Odor Control […]
Commercial cannabis growing, harvesting, drying and extraction operations all release odors that can be considered nuisance odors by employees and/or neighbors, at times requiring the Owner to take action and install cannabis odor control equipment. This blog addresses odors from the first three of these processes (cannabis growing, harvesting, and drying). A subsequent blog will […]
Companies that operate shredders to recycle metals from autos and other scrap are increasingly coming under pressure from regulators to install air pollution control systems, and very frequently, this includes installing particulate matter control devices. The common target of regulators is the emission of fine dust particulate and ‘blue smoke,’ (i.e., oil droplets that evaporate […]
Many wastewater treatment facilities employ a sewage sludge incinerator (SSI) to burn and thereby dispose of dewatered sewage sludge. The types of SSIs used at wastewater treatment facilities include fluidized bed incinerators and multiple hearth furnaces. These incinerators produce a wide variety of air contaminants. The Environmental Protection Agency (EPA) stipulates emission limits for SSIs […]
