Due to the proliferation of chemicals in the environment, special facilities must be set up to clean and treat water. Unfortunately, PFAS have been identified in a great many number of environments.
在船 & 海岸环境 we are working on providing the best PFAS removal services around by blending our years of experience in pollution abatement systems with the latest techniques for remediation and removal.
PFAS是每氟烷基和多氟烷基物质, 一组人造化学物质，包括PFOA, 卵圆孔未闭, 还有很多其他化学物质. These chemicals are found in a substantial number of everyday items, 从食品包装到消防泡沫. After extensive research and analysis, both PFOA and 卵圆孔未闭 have been found in the environment. In water sources, rivers, lakes, as well as in the wildlife and humans worldwide.
The chemical compounds in PFAS do not break down easily. They can take several decades to decay, and this is causing many problems. To protect the health and safety of all US citizens as well as the surrounding environment, the EPA (The Environmental Protection Agency) has indicated that safe levels of PFOA and 卵圆孔未闭 in drinking water must not exceed 70 parts per trillion. 这意味着有很多工作要做.
At the present time, three basic technologies exist to remove PFAS from the water supply.
This is the most common method for treating affected water suppliers. 在合适的条件下, it can provide the steady and adequate removal of PFAS in the water, bringing them down to the desired level under the EPA regulation. Using this sort of carbons-based technology for PFAS, generally results in a much quicker turnaround than it would be for other types of contaminants. Activated carbon can also be recycled as it is seen as non-hazardous waste. Meaning that although the initial cost may be high, you can easily dispose of waste.
If a particular water supply needs more stringent treatment requirements, then synthetic resins are being used over and over the carbon treatment process. 通过使用组合方法, carbon the primary cleaning sources followed by treatment with resins as a polishing bed, you are getting a higher quality water cleaning solution of PFAS Remediation. This has the effect of extending the life of carbon usage and limits the amount utilized overall. Resin, however, is seen as hazardous and therefore requires a more delicate disposal process.
This is a relatively new technology that means that a synthetic reason can be regenerated while still on-site. This PFAS engineering technology can make the resin more economical in the long run. But long-term use of such technology has not been attempted yet as it is still in its infancy., which means the cost-benefit is merely hypothetical. 另外, 目前, it is quite expensive to use the regeneration technology as it requires installation. As time goes on, the efficacy of such a technology will be analyzed and the result determined.
