Application of Selected Sorbent Materials in Removal of Bromates from Water

21.5.2018 | Ing. Ivana Marko, doc. Ing. Danka Barloková, PhD., prof. Ing. Ján Ilavský, PhD., Slovenská technická univerzita v Bratislave, Stavebná fakulta, Katedra zdravotného a environmentálneho inžinierstva
Bromates (BrO3) are classified as hazard substances that can cause carcinogenic diseases. They belong among the elements that are not commonly found in analysis of the drinking water. Bromates appear as by-product from water disinfection by ozone in the water, that contain the higher concentration of bromine ions (BrO). There are several physical and chemical processes that can be used to reduce the concentration of bromates. Adsorption is one of the most frequently used methods for removal of the hazard substances from the water. It allows the application of various type of sorbent materials for instance: active coal, zeolite, GEH, and the other materials with base of iron hydroxide.
The main aim of this work was to ensure the removal of bromates from the water source Dvorníky (Slovak Republic), with selected sorbent materials: granulate active coal, zeolite, GEH, Bayoxide E33, Read – As, Klinopur – Mn, and activated alumina. The results of the laboratory tests are present in the experimental part.

Environmental benefits of using recycled wood to produce agglomerated materials (Part 3)

21.5.2018 | doc. Ing. Milan Gaff, Ph.D., Ing. Kamil Trgala, Ph.D., Ing. Tereza Adamová, Česká zemědělská univerzita v Praze (ČZU), Fakulta lesnická a dřevařská, katedra dřevěných výrobků a konstrukcí
Wood and the materials on its basis fulfil the requirements of an ever-evolving and accelerating society. In addition to naturally grown wood, wood-based materials are frequently used as a basic material for production of furniture and for building constructions as well. Looking at changes in waste management, a significant shift from the waste to the circular economy can be observed. The valuable raw materials are kept in the production cycle instead of landfilling or burning. Wood and wooden products can be efficiently separated in waste management, reused and recycled. The so-called wood waste – old furniture, wooden pallets, window and door frames, demolition wood, used lumber, bark and other wood residues can be reused in particleboard production. Particle board manufacturers in the Czech Republic have adopted progressive waste management and currently use 60% of recycled wood into particle boards. A completed life cycle analysis (LCA) of OSB demonstrates that replacing of 50% of natural fibres with recycled wood has significant environmental benefits. The objective is to push furthermore on effective legislation to promote waste material utilization and thus lead to a more sophisticated waste wood collecting.
