  The degradation of pentoxifylline (PTX) using H2O2, UV, H2O2/UV, Fenton and photo- Fenton processes has been examined in aqueous solution. The influence of various amount of oxidation agent on H2O2, H2O2/UV, Fenton and photo-Fenton reactions were investigated. Initial PTX concentration in Fenton and photo-Fenton was considerated. The addition of inorganic ions (Cl-, NO3-, SO42- and CO32-) on the degradation efficiency of PTX were...

  Publikacja

  • M. Gajewska

  - Environment Protection Engineering - Rok 2015

  Influence of composition of raw wastewater on the efficiency of organic matter and nitrogen removal in multistage treatment wetlands has been examined. Commonly used indicators, like COD/BOD5 and BOD5/TN ratio, determining wastewater susceptibility to biodegradation in conventional treatment technologies were assessed. It was confirmed that multistage treatment wetland may be used for treatment of wastewater with high loads of...

  - Environment Protection Engineering - Rok 2015

  During the last 30 years the increase of interest in low-cost decentralized and small wastewater treatment plants (WWTP) is observed in Europe. For this purpose sand filters, stabilization ponds, mini reactors with activated sludge, trickling filters and treatment wetlands are used. Among the listed facilities treatment wetlands (TWs) offer effective and reliable treatment efficiency, being at the same time low-cost and simple...

• IDENTIFICATION OF ODOR OF VOLATILE ORGANIC COMPOUNDS USING CLASSICAL SENSORY ANALYSIS AND ELECTRONIC NOSE TECHNIQUE

  Publikacja

  • J. Gębicki
  • T. Dymerski
  • S. Rutkowski

  - Environment Protection Engineering - Rok 2014

  The paper compares two methods of analysis of odour of volatile organic compounds: classical sensory analysis and electronic nose technique. Eight volunteers participated in the classical sensory analysis investigations, which lasted two weeks. An instrumental odour analysis involved a prototype of 6-sensor electronic nose designed by the authors. The research performed with this device provided higher reproducibility and reliability...

• Preparation, composition and properties of fish silage produced with post-coagulation sludge

  Publikacja

  • R. Tomczak-Wandzel
  • K. Mędrzycka

  - Environment Protection Engineering - Rok 2013

  Post-coagulation sludge was added to fish fydrolyzates (silage). Silage was prepared using whole sprats. Technology of the process has been modified and sulphuric acid was replaced with phosphoric acid. The objective was to evaleuate the quality of produced silage during storage, particulary the changes of peroxide value and amount of free acids in silage fat.

  - Environment Protection Engineering - Rok 2011

  In recent years, an increase in interest in hybrid constructed wetland systems (HCWs) has beenobserved. These systems are composed of two or more filters with different modes of sewage flow.Based on over eight years of monitoring, carried out at five local HCWs located in the PomeraniaRegion of Northern Poland, the effective removal of organic matter (from 74.9 to 95.5% COD) in theloading range 1.5-17.0 g COD·m-2·d-1 was confirmed....

  - Environment Protection Engineering - Rok 2011

  Factors influencing COD and removal and transformation of N fractions have been investigatedin the conditions of horizontal (SSHF) and vertical (SSVF) flow reed beds. Multistage treatment wetlandin Wiklino ensured a stable and very effective removal of all the analysed pollutants. Based onthe resultsof investigation, it could be assumed that the working conditions of SSHF beds play an importantrole in the transformation of particulate...

  - Environment Protection Engineering - Rok 2009

  Zbadano aktywność powierzchniową i właściwości zwilżające surfaktantu niejonowego - Rokanolu NL6, biosurfaktantu - JBR 425 i ich mieszanin. Na podstawie tych badań określono zdolność tych surfaktantów do usuwania oleju syntetycznego (PAO 6) z piasku. Roztwory surfaktantów zostały użyte do przemywania złoża piaskowego w kolumnie oraz odmywania piasku metodą dynamiczną. Testy kolumnowe z roztworami Rokanolu NL6 i JBR 425 dały niskie...
