For the biological purification of effluents from small to medium-sized civil settlements, an ideal process cycle consists of screening, primary decantation with sludge digestion chamber (Imhoff tank), biological purification and separation of excess sludge. In compact biocombi plantswith filtration, proposed by MITA Biorulli, the biological treatment takes place through a partially immersed roller (biodisc) on which the biomass is formed. In place of the final sedimentation tank, a cloth filter is used, consisting of a horizontal drum in perforated sheet metal covered with a special filter cloth and equipped with an adequate system for removing the separated sludge. The most evident advantages of the system are the minimum energy consumption, the maintenance limited to a few simple interventions, the small size, the constant efficiency even in the face of variable loads and, last but not least, the absence of noise and unpleasant fumes. The biological purification phase takes place with a biodisc made with parallel polypropylene discs mounted on a central axis, the diameter of which varies, according to the size of the plant, from 2.00 m to 2.40 m. The discs are immersed for 40% of their surface in the water to be purified and represent an ideal support for the growth of bacterial flora, the main architect of biological purification. The cloth filter replaces the secondary sedimentation basin. The biologically purified water can reach the drain only by passing through the filter cloth; the surface of this canvas gradually becomes covered with a layer of mud that causes an increase in pressure drops. A level sensor then activates a pump which, by means of a suction unit placed in contact with the cloth, draws, from the inside of the drum, the water necessary for cleaning the cloth itself. The removed sludge is sent back to the primary settling tank, if any, or to another destination (sludge treatment). In addition to compliance with legal requirements, this purification system also responds effectively to important practical needs. Maintenance is considerably reduced compared to traditional systems and can be performed by unskilled personnel. The compact biocombi systems BC series are particularly suitable for small municipalities or hamlets, tourist villages, hotels.
