Compact plants

SERECO has always considered very important to install compact plants for both biological and physical-chemical treatment. In the catalogue there are three different types of compact plants: DBF, VERDE and CF (each one with the relevant options).
The type DBF is a biological plant, very compact, with integral aerobic sludge digestion. It is typically installed for the biological treatment of sewages, with a very high quantity of organic pollutants that can be promptly biodegraded; in fact it is preferred for the treatment of wastewater coming from slaughterhouses, milk transformation industries, food industries in general and the like. The inlet sewage characteristics require a biological treatment to be carefully studied from time to time; this will allow to minimize the overall dimensions and limit the quantity of produced sludge, thanks to the aerobic digestion.
The VERDE type is a biological plant with total oxidation. Its typical installation is for the treatment of civil sewage of small communities which do not have the possibility of connection to the city sewer. In fact it is very used for the treatment of civil wastewater of hotels, holiday villages, communities and the like. For this type of applications, the compact VERDE type plant offers another advantage: it can make use of the treated water to irrigation purposes for the gardens pertaining to the building. The big quantity of water necessary every day for the garden keeping is often sufficiently supplied by the treated water. Moreover the high treatment efficiency of these plants totally excludes the possibility of any bad smell diffusion.
The CF type plant is instead a compact plant for the chemical-physical treatment. Its use is recommended whenever the installation of a biological plant is disadvantageous. This is the case of wastewater containing toxic pollutants which may inactivate the biological mass or when the flows are very irregular and do not allow an adequate time of growth and acclimatization of the bacterial mass. It is in fact very used for the treatment of the wastewater from car washing, laundries, chemical industries and the like. It is also very used for the treatment of the first rain water from yards, for which the gathering and subsequent treatment is required by law. An appreciated merit of the chemical-physical treatments is in fact the property of working in normal condition just after its putting into operation, unlike the biological treatments that require a long start-up time. Just for this reason, the chemical-physical treatment is the only system that can be assumed suitable for the early stormwater treatment. Finally, the CFF type has, as supplement, a sand and/or activated carbon filtration bed for a further decrease of the organic load and suspended solids.
