Immersed aerator OSSI-MIX

for wastewater treatment

The OSSI-MIX (OM) system is a new development in the sludge aeration machines sector. The constructive architecture of the machine is one of the main innovations of the new OM system and is Patent protected. The System is based on the use of a special hydraulic system with a 3-channel centrifugal impeller, which works in a special 12-outlet diffuser. The outlet of the pump is thus spread among the 12 nozzles that deliver the sludge to be aerated into 12 individual mixing chambers. In these chambers the sludge is contacted with the air supplied by a compressor, the air-sludge contact occurs in an high turbulence annular conduit. The OM system delivers twelve jets of aerated mixture, thus producing high levels of dissolved oxygen and a vigorous mixing of the sludge. The OM system achieves better performances with respect to other aeration systems, as a consequence of its integrated operations. The OM system has been designed for a long operational life which translates in low operating costs. All parts subject to wear can be replaced easily from the edge of the tank with the use of simple tools. The impeller has an exclusive fine tuning regulation system. In summary the OM system is constitutes therefore an excellent and unrivalled technical-economical combination for the aeration of sludge, reaching unparalleled results in terms of energy efficiency and maintenance costs.
