  The behaviour of concrete, whether fresh or har dened, depends basically on the beha viour of its components and the r elationship between them, ther efore, obtaining a concr ete with cer tain pr operties depends fundamentally on the concr ete mix design. Concr ete mix design gener ally includes two main steps: 1-Selection of the main components suitable for the concr...

  The paper presents the results of a study of parameters used for determining the amount of organic pollutants in wastewater flowing into a collective wastewater treatment plant with a population equivalent of about 120 000 PE. The plant constituted part of a sewage system. Assays were performed for biochemical oxygen demand (BOD5), chemical oxygen demand (CODCr), permanganete index (CODMn) and total organic carbon (TOC). In addition,...

• Recent developnents in wastewater treatment in constructed wetlands in Poland

  Publikacja

  - Rok 2005

  Nowadays more than 100 constructed wetlands are in operation in Poland. Most of them are one stage wetland systems with horizontal subsurface flow. Such constructed wetlands ensure efficient removal of organic matter (BOD5, CODCr) and suspended solids but efficiency of nitrogen compounds removal in many cases is insufficient.In the period from 1995 to 2003 measurements of removal of contaminations in 11 individual pilot household...

  Acoustic seafloor measurements with multibeam echosounders (MBESs) are currently often used for submarine habitat mapping, but the MBESs are usually not acoustically calibrated for backscattering strength (BBS) and cannot be used to infer absolute seafloor angular dependence. We present a study outlining the calibration and showing absolute backscattering strength values measured at a frequency of 150 kHz at around 10–20 m water...
