Recirculating PAC provides DOC removal for water treatment
Recirculating powdered activated carbon (PAC) removes organic and emerging contaminants cost-effectively for indirect potable reuse applications, thereby avoiding the challenges of large-scale reverse osmosis such as brine disposal for inland regions.
Overcoming Hydrogen Sulfide in North Carolina Collection Systems
Wastewater treatment plant personnel can face public scrutiny over odor emissions from treatment plants and wastewater collection system networks. Hydrogen sulfide (H2S) is the most common cause for odor complaints and is dangerous to life and health, and therefore utilities attempt to mitigate H2S production with solutions such as chemical addition or carbon filters. In addition to odor, H2S converts to sulfuric acid (H2SO4) in collection systems, and can cause millions of dollars of infrastructure damage due to corrosion.
