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.

The Ossi-jet system offers an excellent alternative for aeration and mixing of any civil or industrial liquid. In order to satisfy any type of requirement, it is possible to couple various pumps to various ejectors. Ossi-jet is particularly recommended for biological waste-water treatment plants, chemical waste treatment plants and fish farming.
The different type of impellers and ejectors offered by the Ossi-jet system optimise the following processes:
-Ozonisation / mixing;
AJ - Submerged Aerators
AJ submerged aerators are an extremely flexible and versatile airing system for the treatment of waste-water and in every case air/water mixing is required . Elevated oxygen transfer values, low noise levels, increased reliability, low cost and rapidity of installation are just some of the advantages that our AJ submerged aerators offer.
These aerators are frequently used in waste water treatment plants, especially during homogenisation and equalisation, pre-airing stages, biological oxidation, oxidation-nitrfication, sludge stabilisation and post-airing stages. AJ radial submerged aerators can be utilised for the flotation of greases, oils and solids, at the relevant stages of flotation. This clearly means that they can be utilised during neutralization stages or in airing with high levels of oxigen. Re-circulation of the mixed air and water in the tank is carried out by two different movements: the principal or primary movement (Mp) and the induced one.
