THE USE OF HIGH MOISTURE SEWAGE SLUDGE IN THE CHP UNIT INTEGRATED WITH BIOMASS DRYING AND GASIFICATION

The paper presents the evaluation of the possibility of the use of a biomass with high moisture content in a cogeneration plant with gas piston engine. The dried sewage sludge-derived syngas is used as a fuel. Sewage sludge are characterized by about 70 wt% of moisture content after the dewatering process. The drying process which is applied as the next step requires great amount of energy. For this reason the thermal integration of the drying process with a piston engine which produce a

Structural Changes of Bacillus subtilis Biomass on Biosorption of Iron (II) from Aqueous Solutions: Isotherm and Kinetic Studies

were done using microbial biomass (algae, bacteria, and fungi) as biosorbent for remediation of metal ions from polluted water resources. The biosorption process relies on nature and biosorbent type, and metal species to be biosorbed (El-Naggar et al. 2018). The process of biosorption is associated with many advantages as a low operating cost, biosorbent reuse, the minimized disposal of chemical or biological sludge, detoxification of very dilute effluents with high efficiency, specific metal

USE OF CASING SOIL FROM SPENT MUSHROOM COMPOST FOR ENERGY RECOVERY PURPOSES IN POLAND

Use of spent mushroom substrate (SMC) for energy production appears as a response to the problem with the utilization of this waste throughout the whole year. In the Polish national energy supply system, which is based mainly on hard coal and lignite, use of biomass may contribute to limiting CO2 emissions. The work presents a comparative analysis of the unit emission of CO2, CO, SO2, NOx and particle matter referred to the unit of energy produced from the referenced hard coal, spent mushroom

RESEARCH ON THE CULTIVATION OF NITRIFYING BACTERIA AND POSSIBILITY OF THE BIOMASS STORAGE

The efficiency of nitrification has a great influence on the effect of removing nitrogen from wastewater. Problems with the process are associated with reducing the age of activated sludge, lower temperatures of wastewater in aeration chambers, rapid changes in the amount and composition of wastewater containing toxic substances or inhibiting the oxidation of ammonia nitrogen. The research concerned the possibility of cultivation and storage of the nitrifying bacteria biomass, which could be

Microbial Biomass and Enzymatic Activity of the Surface Microlayer and Subsurface Water in Two Dystrophic Lakes

Nutrient and organic matter concentration, microbial biomass and activities were studied at the surface microlayers (SML) and subsurface waters (SSW) in two small forest lakes of different water colour. The SML in polyhumic lake is more enriched with dissolved inorganic nitro­gen (0.141 mg l–1) than that of oligohumic lake (0.124 mg l–1), the former also contains higher levels of total nitrogen (2.66 mg l–1).

THE POSSIBILITY OF USING OF HYPHOLOMA FASCICULARE MYCELIUM IN DECOLORIZATION OF ANTHRAQUINONE DYE RBBR

The aim of this study was to determine the usefulness of two fungal strains of Hypholoma fasciculare (L1 and L3) for effective decolorization of anthraquinone dye RBBR (remazol Brilliant Blue R). The main part of the work was concentrated on assessment of the influence of immobilization of biomass on the efficiency of RBBR removal. Zoo- and phytotoxicity of after process solutions were evaluated. Differences in the dye removal effectiveness between strains were observed. Decoloration of dye was

Phospholipid fatty acid (PLFA) analysis is considered to reflect the actual condition of the microbial communities because this analytical method is based on the extraction and quantification of phospholipids from all microorganisms in the sample; this method has been applied to Daqu (Jiang et al. 2018). The total concentration of PLFA can be used as an indicator of viable microbial biomass, hence it can help us to understand the

EVALUATION OF DIFFERENT SENSING APPROACHES CONCERNING TO NONDESTRUCTIVE ESTIMATION OF LEAF AREA INDEX (LAI) FOR WINTER WHEAT

Different approaches of non-destructive estimation of the LAI in winter wheat were compared. Plant height had weak relation with the LAI, while estimated biomass showed high logarithmic relationship (R2=0.839). NDRE and REIP were logarithmically well related to the LAI (R2=0.726 and 0.779 respectively). Saturation effect of NDRE and REIP was less than NDVI. Some RGB-based indices also showed good potential to estimate the LAI. Among the indices, Gm, GMB, RMB, and NRMB were better related to the

Effect of Lyophilization on Survivability and Growth Kinetic of Trichoderma Strains Preserved on Various Agriculture By-Products

Growth kinetics of four Trichoderma strains was tested on lignocellulosic by-products in solid state fermentation (SSF). The strains were also analyzed for their survival rate and growth after lyophilization on these carriers. All applied monocomponent and bicomponent media were substrates for the production and preservation of Trichoderma biomass. However, the maximum number of colony forming units (CFU/g dm) was acquired on bicomponent media based on dried grass and beet pulp or grass with

USE OF BIOLOGICAL METHODS FOR REMOVAL OF H2S FROM BIOGAS IN WASTEWATER TREATMENT PLANTS – A REVIEW

Biogas is produced during anaerobic digestion of organic substances by a consortium of microorganisms. Biogas consists mainly of methane (CH4 ) and carbon dioxide (CO2). Other gases such as dinitrogen (N2), water vapour (H2 O), ammonia (NH3), hydrogen sulfide (H2S) and other sulfur compounds could also be found therein. Biogas produced by waste biomass has been recognized as one of the most important alternative energy sources in the recent years. In order to be used as a source of energy to

This strain also produced arabitol from glucose, giving much lower yields, but did not produce it from xylose. The new strain can be successfully used for arabitol production from abundantly available sugars found in plant biomass.
