The final water filtration that comes from the purification plants offers many advantages and compensates for the lack of possible process. High values of Suspended Solids (SS) always involve negative changes even of other parameters.

The biorulli biological oxidation system makes use of one or more rotating contact cylinders for the reduction of the organic matter waste water contains. Each contact cylinder is composed of a shaft, onto which polypropylene discs are fitted; discs are variable in number according to the model. The shaft is rotated very slowly (1 ÷ 5 rpm, depending on the model and the effluent properties) by means of a motor-gearbox set.

It is the smallest single-piece unit series. It involves a set of rotating discs complete with tank and cover, both manufactured from fibreglass-reinforced polyester. It is an economical version, easy to install.

This is the most widely used single-piece unit series. The tank can be made, at choice, in treated and painted carbon steel or in AISI 304 stainless steel. The cover, in both cases, is manufactured in fibreglass-reinforced polyester. It is noteworthy for the ease of installation (limited civil engineering works, factory-assembled unit).

This is the latest entry to the single-piece unit series. The tank is made from treated and painted carbon steel, the cover in fibreglass-reinforced polyester. It associates the advantages of a single-piece unit (simplicity of installation, limited civil engineering works) with the possibility of application in installations already of a considerable size. The transport of these single-piece units is of the special category, but still at acceptable costs (it does not need a police escort).

When for economic reasons or for special geographical situations we must abandon the creation of a centralized system, the use of small plants for wastewater treatment for civil use is required.

The flow of water and sludge coming from the previous phases of treatment (whether biological or physical-chemical) is introduced into the intermediate zone of the tank, just below the lamellar pack. A uniform distribution of the effluent over the lamellar pack is effected by means of a diffuser.

mitadaf is an innovative dissolved air flotation system. Its exceptional solid/liquid separation and/or sludge thickening efficiency is the result of the combined systemof uniform hydrodynamics and filtration with a bed of micro air-bubbles: an equipment of new concept developed by MITA.

Dissolved air reactors. mitasat high efficiency air saturators allow complete dissolving of the injected air, without excess air relief valves. The standard model is completely manufactured in AISI 316. Executions in special steels and alternative materials are available on request. Typical applications (using mitadaf floatation units): paper-works, food industry, dairies and cheese factories, wineries, textile industry, industrial laundries, chemical plants, refineries. They are moreover employed in civil and industrial biological treatment plants both for primary and secondary clarification and for sludge thickening.
