Filtration process is one of the basic and essential processes in technological systems for treatment of municipal, community and industrial wastewater treatment. Filtration process is a subject of numerous published research and theoretical elaborations. This publication concerns theoretical analysis with basic character, and is a verification of theoretical analysis and physical equations describing process of filtration aided with empirical formulas.
The concept of place has been present in human geography for almost half a century. The human geographers looked for the answer about genesis of place category in different sociological or psychological aspects with the basis of space dimension. In last two decades a few of them referred that idea to communication processes. Inspired by the views expressed by the latter group of scientists, we are asking: how is creating a place? We put forward thesis that a special type of place making is social communication that works continuously on the principle of the palimpsest of overlapping meanings through messages arising in several dimensions. Our assumption is that every place is creating (overwriting) a social subject – an individual or a group, that will build communication in three dimensions: within a space/place (W), about a space/place (A), and/or between people and a space/place (B).
