AI Technical Summary
Existing technologies are insufficient for efficiently removing various PFAS and other recalcitrant organic compounds from water, and traditional GAC systems suffer from problems such as short penetration time, high cost, and large footprint.
The system, which combines submicron powdered activated carbon (SPAC) with a ceramic membrane filter, achieves efficient adsorption and separation of pollutants by using multiple adsorbents, including SPAC, IX resin and coagulant, in a single reactor, combined with cross-flow filtration using a high-speed cross-flow ceramic membrane filter.
It improves the removal rate of pollutants such as PFAS, extends the system's penetration time, reduces the amount and cost of waste material processing, simplifies the processing flow, and reduces the required floor space.
