Aerosol in indoor microenviroment of homes
Pařík, Radim ; Braniš, Martin (advisor) ; Hovorka, Jan (referee)
This literature review is composed of resources from Web of Science. The study deals with problematics of the indoor air pollution of homes. It is focused on the aerosol, especially PM2,5 particles, which present the biggest danger for human health. This work points out the analysis of indoor and outdoor emission sources, distribution of particles, levels of pollution in the different geografical, social and cultural regions and health effects of these particles. Key words: aerosol, homes, indoor environment, air quality, fine particles

Optimization of drinking water treatment with double-stage separation of suspension
Pařík, Radim ; Pivokonský, Martin (advisor) ; Vašatová, Petra (referee)
This diploma thesis is aimed at the evaluation of the efficiency of surface water treatment technology in water treatment plant U svaté Trojice (Kutná Hora, Vrchlice reservoir). The plant performs destabilisation of impurities by coagulant aluminium sulphate (Al2(SO4)3 . 18 H2O) followed by aggregation induced by mixing with perforated baffles. Suspension is removed by double-stage separation process by means of sedimentation and filtration. When increased concentrations of manganese occur in raw water, manganese is removed by means of oxidation by potassium permanganate. Firstly, the quality of raw water was analysed. Then, the reaction conditions for the effective destabilisation (pH, dose of coagulant) were set using the jar tests. Moreover, sedimentation analysis was used to evaluate the properties of formed suspension and the length of filter cycles was assessed. Measurements were conducted between September 2012 and February 2013. Average value of raw water pH was 7.3, alkalinity was 1.64 mmol/l. DOC concentrations during September and October 2012 were equal to 6.7 mg/l and during November 2012 - February 2013 were 7.6 mg/l. Very low concentrations of aluminium (< 0.02 mg/l) were ascertained throughout the whole period investigated. Results of the jar tests showed that the optimum pH for...
