3. Constructing a Pipe-Bound City : A History of Water Supply, Sewerage, and Excreta Removal in Norrköping and Linköping, Sweden, 1860-1910
Abstract : In the mid- to late 19th century, modern pipe-bound water and sewer systems proliferated in European cities, a development that has sometimes been regarded as a necessary result of a sanitary awakening and the progress of science and technology. By analyzing the introduction and subsequent expansion of water, sewerage, and excreta collection on the local level, in the Swedish cities Norrköping and Linköping, this oversimplified picture is questioned.

4. Controlling and monitoring of deammonification process in moving bed biofilm reactor
Abstract : It is considered that partial nitrification combined with anammox, named deammonification, is more environmental friendly compared with conventional nitrification/denitrification due to decrease energy requirement, low emission of CO2 and N2O. Dissolved oxygen (DO) is a significant parameter influencing the nitrogen removal rate and activity of different microorganisms. READ MORE

5. Towards sustainability of environmental protection : recovery of nutrients from wastewater filtration and the washing of arsenic contaminated soils
Abstract : Conventional methods for wastewater treatment and remediation of the sites withcontaminated soils focus on protection of human health, receiving waters and theenvironment. Towards this end, these methods concentrate on the reduction or removal of polluting substances, and therefore, are not well suited for creating resources through the recovery of nutrients, energy and decontaminated soils.
