As environmental regulations become more stringent and global water demand increases, new technologies are being developed to meet these new requirements. Veolia's CoaFil meets the very strict requirements of the oil and gas industry for discharge, water reuse or reinjection applications.
It allows for higher oil and solids feeds while achieving very low discharge levels (less than 1 part per million (ppm)). The oleophobic media repels oil for an easier backwash and reduces the risk of ‘mud-balling’ for a better, consistent outlet quality.
As a single technology, CoaFil eliminates the need for conventional secondary and tertiary treatment steps such as the Induced Gas Flotation, nutshell filters and media/sand filters. This not only reduces cost but also simplifies the entire treatment process.
With four models available, CoaFil is fully designed and standardised to the standards of the oil and gas industry. It is available as a vertical vessel with internal and media supply for single or series units based on feed and discharge requirements. The media of existing filters can also be replaced by CoaFil’s media and pilot testing is available for feasibility and performance.
