Comparative Economic and Technological Analysis of the Various Sewage Sludge Treatment Technologies

The treatment of communal sewage results in large quantities of sewage sludge, a by-product that has imposed a considerable load on the environment in the recent decades. As a result, the elaboration of environmental-friendly procedures has become a priority worldwide. The main trend of technological development was the environmental-friendly disposal of...

Comparative Analyses of Various Redworm/Brandling Worm (Eisenia fetida) Stocks

The environmentally sustainable technology we want to develop is a biotechnological process focusing on the industrial use of the abilities of redworm/brandling worm (Eisenia fetida). This species, takes part in further exploration of decomposing organic substances as a biological agent, producing thereby a by-product (vermicompost) that plants can use very well. The genetic variability...

Multivariate Impact Assessment of Environmental Factors during Decomposing Sewage Sludge

Biotechnological processes fall into the category of environment-sensitive technologies. In view of the fact that we work with organic substances and living agents special attention should be paid to weather risks, the most important of which are drought and snow blanket and large quantities of stormwater falling during relatively short time. In addition...
