Removal Of PFCs With Activated Carbon
In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

Ten years ago, KLa Systems was presented with the challenge of finding a more wear-resistant material for our jet aeration nozzles and decided to upgrade to Kynar PVDF, which is extremely chemical and wear resistant.
Phosphorus and nitrogen, while necessary elements for life, when concentrated in the effluent of a wastewater treatment plant, are harmful to the environment, especially aquatic plants and animals. When concentrated amounts of these elements enter bodies of water, it causes algae blooms, which reduces dissolved oxygen in the water and can be damaging to animal populations. It can be a very serious problem for natural areas downstream of industrial or municipal discharge.
Meeting the demand for clean water has never been more challenging. Communities around the world are facing a growing water stress – an insufficient supply, in terms of water quality or water quantity – and often both. Many are turning to potable reuse and drinking water remediation to meet these demands. The TrojanUVFlex®AOP can be part of the solution. This UV advanced oxidation system destroys a range of chemical contaminants while simultaneously providing final treatment, helping municipalities relying on lower quality water sources to continue producing high-quality potable drinking water.
Steel Mini Frac Tank rentals are perfect for smaller sites where space is limited.
