In the article the problems of cleaning of sewages are considered on cleansing buildings of the motor-car washings. The constructions of the known flowsheets of cleaning of sewages of autowashings are analysed. The on principle new flowsheet of cleaning of sewages of autowashings is offered, which leans against financial viability with the maximal diminishing of capital costs and maximal carrying...
In the paper an Equivalent Water Thickness (EWT) determination as a way of observing gravity variations is described. Since raw data acquired directly from Gravity Recovery and Climate Experiment – GRACE satellites is unsuitable for analysis due to stripes occurrence, a filtering algorithm must be used. In this paper, authors are testing two isotropic (Gauss, CNES/GRGS) filters and two anisotropic...
The article presents the experience related with the manufacture of utility castings poured in bentonitebonded sands on a pilot stand. The technological guidelines were presented for the ductile iron castings weighing 40 kg and 10 kg. For individual castings, the mould technology has been developed, cross-sections of the gating and feeding systems were calculated, and pilot pattern equipment was designed...
Badania wykonano w mechaniczno-biologicznej oczyszczalni ścieków, typu SBR (Sekwencyjny Biologiczny Reaktor) o przepustowości 365 m³·d⁻¹. W badanym obiekcie zastosowano trzeci stopień oczyszczania - chemiczne strącanie fosforu polegające na dodawaniu do ścieków preparatu PIX (41% roztworu siarczanu żelazowego). Wpływ ilości dodawanego siarczanu żelazowego (PIX), na jakość oczyszczania ścieków okazał...
