Cullet As Filter Medium For Swimming Pool Water Treatment
PublicationKontrola jakości wody w basenach kąpielowych może być prowadzona poprzez oczyszczanie wody z uwzględnieniem filtracji i dodawaniemśrodków dezynfekcyjnych. Zanieczyszczenia wody nie zawsze mogą byćskutecznie usuwane przy stosowaniu konwencjonalnych metod uzdatnianiawody. W doświadczeniu zbadano osady powstałe na złożu piaskowym,stwierdzono nieefektywną pracę filtrów piaskowych. Porównano dwazłoża filtracyjne: piasek kwarcowy i...

Densimetric and ultrasonic characterization of urea and its derivatives in water
PublicationW oparciu o pomiary gęstości dla serii roztworów jak i rozpuszczalnika wykonanych w temperaturach 15, 20, 25, 30 i 35oC wyznaczono pozorne molowe objętości mocznika, N-metylomocznika, N,N'-dimetylomocznika, N,N,N',N'-tetrametylomocznika, N-etylomocznika, N,N'-dietylomocznika jak i N-butylomocznika w wodzie. Dodatkowe pomiary szybkości dźwięku przeprowadzone w temperaturze 25oC pozwoliły obliczyć ściśliwości adiabatyczne, pozorne...

Review of the determination of modern used pesticides in water samples
PublicationThe increasingly widespread application of pesticides causes that larger amounts of them are entering the environment. Their presence in sources of drinking water, essential to life, is a particular danger. For these reasons it is important to monitor and analyse pesticide residues in the environment. The analysis of environmental samples for the presence of pesticides is very difficult. Firstly, the processes involved in sample...

Enhancement of the Brayton cycle efficiency by water or steam utilization
PublicationIn the paper, thermodynamic analysis of two modifications of a Brayton cycle into enhancement cycles with water/steam injection are discussed. The first one deals with a STIG modified system with both interstage compressed air cooling and air heating (heat regeneration) before combustion chamber. The second one, mainly devoted to higher steam/air ratio, is connected with separate steam production in a HRSG. The analysis has been...

The Effect of Water and Frost on Fatigue Life of Asphalt Concrete
PublicationThis paper presents testing of fatigue life of asphalt concrete that has been subjected to action of water and frost. Simulation of water and frost action was based on the original AASHTO T283 method and its modification. The original method was modified in such a way that instead of a single freeze-thaw cycle, 50 and 150 cycles were applied. Fatigue life was measured in the indirect tensile fatigue test in the Nottingham asphalt...

Water sorption and blistering of GFRP laminates with varying structures
PublicationThe microstructures, water absorption as well as blistering was studied for bi- and tri- axial glass fibre vinyl ester and polyester -matrix laminates coated with gel coat layer and uncoated. The effect of manufacturing technique on water sorption characteristics was considered. It was found that water sorption characteristics of GFRP depend on manufacturing methods. The least water intake was found for specimens having perfect...

Sampling Procedures in Studies of Cloud Water Composition: A Review
PublicationThe authors set out and classify the principles of operation of known types of cloud water collectors, and critically review their advantages and drawbacks. Analysis of the literature has yielded information on the parameters of various type of collectors—sampling time, the type of cloud from which the water sample was taken, droplet diameter collected with 50% efficiency (cut off), sample analytes/ parameters determined, types...

The influence of the local pipeline leak on water hammer properties
PublicationPrzedstawiono wyniki eksperymentalnej i numerycznej analizy zjawiska uderzenia hydraulicznego. Pomiary przeprowadzono dla przewodu MDPE o długości 36 m, w którym zamodelowano lokalną nieszczelność. W tym celu, w pewnej odległości od zaworu umieszczonego na końcu przewodu zainstalowano kształtki imitujące lokalny wyciek. Przeprowadzono analizę otrzymanych charakterystyk ciśnienia i wyznaczono parametry: okres oscylacji, amplitudę...

Balance errors in numerical solutions of shallow water equations
PublicationThe analysis of the conservative properties of the shallow water equations is presented in the paper. The work focuses on the consistency of numerical solution of these equations with the conservation laws of mass and momentum. The investigations involve two different conservative forms which are solved by an implicit box scheme. The theoretical analysis supported by numerical experiments is carried out for rectangular channel...

Investigation of properties of swimming pool water treatment sediments
PublicationDwa rodzaje osadów pochodzących z instalacji basenowych zostały scharakteryzowane i otrzymane wyniki przedyskutowane, w szczególności flokuły, które zatrzymały się na filtrze piaskowo-żwirowym i następnie zostały usunięte w płukaniu zwrotnym oraz osady z dna niecki basenowej zebrane tzw. odkurzaczem wodnym. Lepsze zrozumienie struktury i właściwości osadów powinno usprawnić usuwanie cyst Cryptosporidium z basenów i w efekcie podnieść...
