The water process via the DAF is cloudy instead of being clear. Why is that?
The cloudiness come from the micro bubbles encapsulating the oil droplets. They rise to the surface later to be skimmed of by a device. After the device does its job you will SEE clear water. How clean it will be is another issue. This pre 1950 technology is slowly being phased out for modern microbial cleaning technology. Chlorine is no longer being used, the water quality is that of natural springs, no erosion of waste treatment facility. The naturally processed water will be potable once again. Reduces water pulled from reservoirs and underground water tables. The home units are coming online. In 20 years the waste treatment facilities will be a museum artifact.
