Assessment of natural-fiber ceiling materials for room acoustics: comsol multiphysics simulation
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)Low-frequency indoor noise is difficult to control in small rooms because standing waves create strong spatial non-uniformity and resonance-driven peaks in sound pressure level (SPL). This study assessed sustainable ... -
Biofilm-driven H₂S biotransformation in a high-surfacearea biofilter packed With KOH-modified biochar and FECO₃-modified CLC waste inoculated with Pseudomonas spp..
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)This study provides an in-depth mechanistic assessment of H₂S biodegradation in a thermally and hydraulically controlled vertical biofilter (1.0 m height, 0.14 m width) packed with KOH-activated sewage-sludge biochar ... -
Effect of perforation hole shape and angle on sound absorption in perforated plastic panels
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)This study investigates the influence of hole shape on the sound absorption performance of perforated plastic panels. Circular, square, diamond, and teardrop curve shapes were selected for this study. A series of ... -
Effectiveness of water treatment processes in removing precursors of chlorinated organic substances from mixtures of groundwater and surface water
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)Due to the correlation of UV254 and UV272 absorbance with the formation of oxidation and disinfection by-products, it is a very important indicator in assessing the effectiveness of water treatment processes. The aim ... -
Investigation of the removal of cations from aqueous solutions using sapropel
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)Sapropel is a sediment found at the bottom of lakes, consisting of both organic and inorganic materials. Water contains various cations, such as ammonium, calcium, and magnesium, which are generally harmless to human health; ... -
A novel thermal criterion for bubble destruction in hydrodynamic cavitation: numerical modeling and experimental validation
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)This research investigates the conditions precipitating the surface instability of spherical bubbles and develops a novel thermal criterion for their terminal collapse during hydrodynamic cavitation. A new mathematical ... -
Preliminary study of acoustic and physical properties of foamed paper mill sludge panels
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)This preliminary study investigates the acoustic and related physical properties of panels manufactured from modified paper mill sludge (PMS) using a foaming technique. PMS is a by-product of the pulp and paper ... -
Research of digestion of cattle manure and chicken dung mixture with iron-based additives
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)This study evaluated the anaerobic co-digestion of cattle manure and chicken dung (70/30% ratio on a DS basis) supplemented with iron-based additives (SBGx, SBGx Plus, and BC. Atox Scon) under continuous mesophilic conditions. ... -
Spatiotemporal variation of soil heavy metal contamination in urban intersection areas and the vicinity of a former military missile base in Raseiniai district, Lithuania
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)The accumulation of heavy metals (HMs) in urban and protected area soils results from multiple anthropogenic emission sources, including vehicular traffic and historical land use. This study aimed at evaluating the levels ... -
Variation of biogenic nutrients in lake water under different levels of anthropogenic impact
(13th International Conference “Environmental Engineering” (ICEE-2026), 2026)This article analyzes the water quality of three lakes under different anthropogenic influences. It examines seasonal changes in biogenic substance concentrations and pH, as well as the impact of environmental use on ...
