Anaerobic digestion is widely used as an important source of renewable energy. With the increasing number and capacity biogas plants also, adequate treatment technologies for whole digestate – residue from anaerobic are gaining attention. In this study state art processing analysed, currently schemes various technological processes involved evaluated. The combines data experiences existing large-scale facilities in Austria, Germany, Switzerland Italy, well know-how technology providers...
This was a detailed investigation of the seasonal occurrence, dynamics, removal and resistance human-associated genetic Bacteroidetes faecal markers (GeBaM) compared with ISO-based standard indicator bacteria (SFIB), human-specific viral one phage in raw treated wastewater municipal domestic origin. Characteristics selected activated sludge treatment plants (WWTPs) from Austria Germany were studied detail (WWTPs, n = 13, connected populations 3 to 49000 individuals), supported by...
Impact of strip gas composition on side stream ammonia stripping, a technology aiming at the reduction high levels in anaerobic reactors, was investigated. Evaluation effect oxygen contact during air stripping showed distinct, though lower than perceived, inhibition microflora. To circumvent, feasibility and possible constraints biogas flue as alternatives were studied. Experiments, with bicarbonate model solution digestate, conducted. It demonstrated that performance is negatively...
The present study investigated the removal of ammonia from anaerobic digester effluent using membrane contactors. For mass transfer, hollow fiber contactors offer a multitude advantages compared to stripping technologies. In conventional applications contactors, rich solution circulates through fibers. this kind application, very high content suspended solids in effluents requires an additional step order guarantee undisturbed operation conditions. new approach, fibers were simply submerged...
Lactic acid is an important biorefinery platform chemical. The use of thermophilic amylolytic microorganisms to produce lactic by fermentation constitutes efficient strategy reduce operating costs, including raw materials and sterilization costs.A process for the production Geobacillus stearothermophilus directly from potato starch was characterized optimized. DSM 494 selected out 12 strains screened activity ability form as major product anaerobic metabolism. In total more than 30 batches...
Recently, a new type of wastewater treatment system became the focus scientific research: mesh filter activated sludge system. It is modification membrane bioreactor (MBR), in which filtration process serves for separation. The main difference that used instead membrane. effluent not same excellent quality as with bioreactors due to much lager pore sizes mesh. Nevertheless, it still resembles currently standard system, process. shows high future potential an alternative where small footprint...
The effluent of a 500 kW biogas plant is treated with solid separation, micro filtration and reverse osmosis to achieve nutrient recovery an quality which should meet disposal into public water bodies. After the osmosis, ammonium concentration still high (NH4-N = 467 mg/l), amongst other cations (K+=85 mg/l; Na+=67 Mg2 + =0.74 Ca2 =1.79 mg/l). aim this study was remove by ion exchange. Acidic gel cation exchange resins clinoptilolite were tested in column experiments evaluate their capacity,...
Abstract Process-based crop growth models have become indispensable tools for investigating the effects of genetic, management, and environmental factors on productivity. One source uncertainty in model predictions is parameterization, i.e. estimating values input parameters, which carried out very differently by modellers. simple (SSM-iCrop) one detailed (APSIM) maize ( Zea mays L.) were partially or fully parameterized using observed data from a 2-year field experiment conducted 2016 2017...
A large-scale scaffold processing method with injection molding has been successfully developed. Water was used as afoaming agent for the new technique. NaCl a porogen to achieve an open-cell structure. Organic solvents, which are common foaming agents polyurethane, where not used. Toxic remains in polymer were therefore prevented. Pore size and porosity adjustable through process parameters. parameter study showed that increase pressure, plasticize speed, cylinder, mold temperature raised...
In treating textile wastewater, the application of membrane bioreactor (MBR) technology showed high efficiency in COD and BOD5 removal. However, insufficient colour removal was achieved for possible reuse. The aim work presented this paper to test performance chemical advanced oxidation on elimination downstream an MBR. To improve quality effluent three different treatments were tested at lab-scale: ozonation, chlorination hydrogen peroxide oxidation. Colour, controlled order assess...
