one embodiment of a daf system 10 fig1 and 2 induces micro bubbles into a specially modified dirty water micro bubble generator pump 20 receiving air from an air source 119 the micro bubble generator pump 20 forces compressed air into the pressure part of the pump 20 and forces fluid through piping 17 receiving from the water body 65 the formed micro bubbles mix with the water and proceed to a saturation tube 120 which comprises a wider section of the piping 17 the saturation tube 120 provides the bubbles with residence time to distribute into the water the saturation tube 120 is followed by a cracking valve 100 which restricts flow and causes pressure to build in the saturation tube 120 to assist in bubble mixing the micro bubble solution then joins with the main flow 18 the main flow 18 proceeds through a serpentine pipe along which are two injection ports in this particular embodiment 10 through a first injection port 103 is inserted a coagulant from tank 104 through a second injection port 106 downstream of the first injection port 103 is inserted a flocculant from tank 105 in an alternate embodiment the flocculant can be inserted directly into the inflow basin 29 it is believed that coagulant causes biomass such as algae to form flocs since the surface charge is altered these flocs form among the micro bubbles the flocculant then attaches the flocs together around the bubbles this embodiment of a daf filter system 10 has an inflow compartment or basin 29 into which the micro bubble.
