COMPRESSED AIR QUALITY INCREASE FOR ROLLING STOCK PNEUMATIC SYSTEMS BASED ON ENERGY EFFICIENCY

The energy efficiency increase problem for railway rolling stock pneumatic systems compressed air preparation is directly connected with its purification and drying technology choice. In the presented materials in the article, the authors find a solution to the problem based on realization analysis of different factors that affect compressed air quality, purification and drying technology choice, as well as based on energy efficiency analysis. To realize the energy-saving events at railway

Resource-Saving Technologies of Treatment of Polluted Washing Water for Transport Companies

Dedicated to the development of resource-saving polluted washing water treating technologies for transport companies. The article suggests methods of water purification with regard to scientifically grounded requirements to the quality of the water used and the required degree of purification and The article also considers the method of selecting efficient methods of sewage water treating, when a selective removal of individual polluting ingredients should be done. For this purpose we have

INVESTIGATION OF FUNCTIONAL DIVERSITY AND ACTIVATED SLUDGE CONDITION USING BIOLOG® SYSTEM

microbial communities, collected from WWTP “Klimzowiec” in Chorzów with the excess sludge subjected to the purification process, and then long-term adaptation in laboratory conditions. Changes in the functional diversity of activated sludge during the adaptation in the lab-scale were verified. It was found that the acclimatization process plays a crucial role in sludge adaptation to the laboratory environment. In addition, it has been shown that subjecting the excess sludge to

unreacted calcium compounds in the product discharged out of the system. In order to control the optimum temperature from the point of view of exhaust gas purification processes water is injected into the reactor. Another element of the FGT system layout is a bag filter divided into several compartments. Depending of the filter’s design it is possible to separate one or more of the bag filter compartments that enables the boiler to work at full load and at the same time allows carrying out work, e.g

THE REUSE OF WASHINGS FROM POOL FILTRATION PLANTS AFTER THE USE OF SIMPLE PURIFICATION PROCESSES

+ 20 minutes of slow mixing at 20 RPM + 30 minutes of sedimentation) [26]. The preliminary studies have also shown the possibility of using a coagulant used in the pool water purification process [10, 14]. For this reason it was decided to use two types of coagulants: dialuminium pentahydroxychloride solution for washings from pools P2, P3, P4, P5 and aluminum sulphate solution for other pools. 3. CHARACTERISTICS OF RESEARCH OBJECTS The research was carried out for 20 pool water treatment

APPLICATION OF POTASSIUM FERRATE(VI) FOR OXIDATION OF SELECTED POLLUTANTS IN AQUATIC ENVIRONMENT – SHORT REVIEW

important module for the purification of this type of wastewater should be their oxidation, mostly based on the ozonation or chlorination process. Unfortunately, both these processes have major disadvantages: ozonation is a cost-intensive process, whereas chlorination causes secondary pollution of wastewater with chlorine compounds [6]. In order to reduce the costs of wastewater treatment and to obtain at least a partial distribution of pollutants, K2FeO4 was used for this purpose. Under laboratory

In certain cases, the oligotrophs were a predominant population, pointing to efficient purification processes in oil refinery wastewaters (Petrovic et al. 1986; Kolarević et al. 2011). However, there is a lack of study on oligotrophic nitrifiers or denitrifiers microbiome in the sewage treatment ecosystem (STE). The STE is composed of three purification crafts, including grille filtration, constructed rapid infiltration (CRI), and an artificial wetland in turn

. The biomass was dissolved with physiological saline and centrifuged. The pellet was used for gDNA isolation. The supernatant was filtered (0.22 μm membrane filter, Sartorius, France) and used for eDNA isolation. Extracellular DNA isolation was conducted partially by the method described by Wilson (2001), while gDNA isolation was done with a gDNA purification kit (Fermentas K0512, Thermo Fisher Scientific Inc., USA). Thus, gDNA and eDNA were partially purified. Ultimately, gDNA and eDNA values were
