During the design of the device, the required output parameters, energy efficiency, the minimum required area for the device and the minimum costs for staff were taken into account.

The technology of the delivered device is based on the DAF flotation described in point 1.1.1. The difference compared to the previously described technology is mechanical pretreatment. The entire mechanical pre-treatment plant combines a pool that is divided into four sedimentation tanks, in the first there is a sedimentation of solid particles, and the second has the function of a pump shaft. Water from the pre-pumping shaft is pumped onto a fine rotary drum sieve by means of which coarse suspended particles larger than 1 mm are separated (Figure 8). The waste thus separated is collected in a communal bin. The mechanically purified water goes gravitationally to the third chamber. The third and fourth chambers serve as an equalization pool.
