The Use of Organic Coagulants in the Primary Precipitation Process at Wastewater Treatment Plants
PublikacjaMeasurements for determining the effect of chemically enhanced primary treatment (CEPT) on the efficiency of pollutant removal from wastewater were carried out using conventional inorganic coagulants PIX113 with polymer A110 (Kemipol, Police, Poland) and unconventional cationic organic coagulants Cofloc (Attana, Coalville, UK) C29510 (Kemipol, Police, Poland) and Sedifloc 575 (3F Chimica, Sandrigo, Italy). The average removal efficiency...

The role of microbial coagulants on the physicochemical, proteolysis, microstructure and sensory properties of low-fat Edam cheese manufactured from ultrafiltered buffalo milk
PublikacjaThis work investigates the influence of using microbial coagulants, including Rhizomucor miehei (MCR) protease and Cryphonectria parasitica (MCC) protease, on the quality characteristics of low-fat Edam cheese made from ultrafiltered buffalo milk (LFUE). Concurrently, a benchmark with calf rennet (CR) has been also performed. Throughout a 90-day ripening period, the cheeses were assessed for their physicochemical features, proteolysis,...

Speciation of Iron in the Aquatic Environment
PublikacjaIron is one of the basic metals occurring in the aquatic environment and it is considered a macroelement with regard to live organisms. This metal has a broad range of applications that, together with factors conditioning its chemical transitions, results in the occurrence of many iron species in water. Depending on water and land development type, as well as the use of water for household and industrial purposes, iron may be found...

Iron and manganese removal effects using zeolites
PublikacjaUsunięcie związków manganu i żelaza z wód podziemnych jest szczególnie ważne ze względów septycznych. Związki te powodują nieprzyjemny smak wody, w warunkach aerobowych tworzą osady. Związki te wytrącają sie w sieci wodociągowej.Celem badań była analiza przydatności naturalnego i modyfikowanego zeolitu jako materiału adsorpcyjnego do usuwania żelaza i manganu. Wprowadzenie modyfikowanego zeolitu umożliwiło uzyskanie dużej poprawy...

Lack of magnetoacoustic emission in iron with 6.5% silicon
PublikacjaZjawisko emisji magnetoakustycznej (EMA) na ogół tłumaczy się dwoma przyczynami: ruchem nie 180-cio stopniowych granic domenowych (1) lub kreacją i anihilacją domen magnetycznych. Artykuł prezentuje silne dowody na poparcie faktu, że to właśnie ruch granic nie 180-cio stopniowych odpowiada za powstawanie efektu EMA. Wynika to z wyników pomiarów dających zerowe natężenie efektu EMA przeprowadzonych dla szerokiego zakresu naprężeń...

Cast iron in the 19th-century building equipment
PublikacjaCast iron is a material, characteristics of which enable to receive extremely artistic elements. It maintains good strength properties at the same time. That combination of these seemingly contrary traits makes it a commodity that was widely used in the 19th century industry and architecture. These usages were not only as decorative elements, technical and structural ones. The production of new household utilities started, which...

Advances in mass spectrometry for iron speciation in plants
PublikacjaIron is an important nutrient essential for plants and critical for human health. The state-of-the art of methods for iron speciation in cereal grains and plant fluids is critically reviewed. Particular attention is given to the latest developments in the coupling of HPLC with the parallel ICP MS and electrospray ionization (ESI) MS/MS detection, usually QTOF MS or Q-Orbitrap MS, for the identification and quantification of iron...

Iron complexes with terminal and nonbridging phosphanido ligands
PublikacjaThis review discusses known iron complexes with terminal-bonded and nonbridging phosphanido ligands R2Pand their analogs, such as phosphanylphosphanido, borylphosphanido and oligophosphanido groups, that have been reported since 1960s. Particular attention is focused on the synthesis and structural features of these complexes, which have a direct impact on their philicity and further reactivity. Moreover, their application in catalysis...

Cavitation Erosion of Nodular Cast Iron - Microstructural Effects
PublikacjaThe paper deals with susceptibility of nodular cast iron with ferritic-pearlitic matrix on cavitation erosion. Cavitation tests were carried out with the use of a cavitation erosion vibratory apparatus employing a vibration exciter operated at frequency of 20 kHz. The study allowed to determine the sequence of subsequent stages in which microstructure of cast iron in superficial regions is subject to degradation. The first features...

Application of ferric chloride for arsenic removal in the integrated process: coagulation/microfiltration
PublikacjaThe study presents results of using iron coagulation integrated with microfiltration to remove arsenic from water. Tested samples of natural groundwater contained approximately 32 μg/L of arsenic, 0.13 mg/L of iron and 0.085 mg/L of manganese. As a coagulant the aqueous solution of ferric chloride was dosed in portions from 1.0 to 10.5 mg/L. In the research microfiltration membranes with 400 kDa MWCO were used. Tests indicated...
