The temperature is one of the main parameters governing the biological reactions in a trickling filter. The present model proposes a set of equations applicable for the determination of a temperature profile, and therefore of an average temperature, inside the trickling filter, when the flowrate and the temperature at entry of the liquid, the ambient air conditions (temperature and humidity) and the thermal exchange coefficients of the tower are known. Moreover, the airflow induced by natural draft is also computed when the head loss coefficients in the media and at entry are known. Beside this formulation, the first results of modal fitting on pilot plants are discussed. With few further developments, the method could be useful for the optimization of the operating temperature in a trickling filter which guarantees a sufficient airflow rate in the tower. [less ▲]

Many phenomena, especially physical ones are by nature continuous. Others, although discrete, can be transformed in statistical surfaces by means of potential functions. The construct generated in this way from land cover maps allow the quantitative, qualitative and geographic study of the phenomenon. It is advantageous to consider these statistical surfaces as geographical models. This is particularly true of urban potential surface. The potential fields are new generalised bands and can be utilised for realisation of color composite images called “colorama”. Further the potential fields allow to form a synthetic image which can by submitted to an automatic classification. The result is a chloropleth map of ecological landscape units. [less ▲]
