Mature Landfill Leachate as a Medium for Hydrodynamic Cavitation of Brewery Spent Grain
نویسندگان
چکیده
In this study, we evaluate the usefulness of mature landfill leachate (MLL) as a carrier allowing hydrodynamic cavitation (HD) brewery spent grain (BSG). The HD experiments were conducted using an orifice plate with conical concentric hole 3/10 mm (inlet/outlet diameter) constriction in device. initial pressure was 7 bar and number recirculation passes through zone reached 30. results showed that complex organic matter degraded solubilized when cavitating MLL BSG mixture. biochemical oxygen demand (BOD5) increased by 45% BOD5/total chemical (COD) ratio 69%, whereas COD, total solids, nutrient concentration dropped noticeably. However, Fourier transform infrared photoacoustic spectroscopy (FTIR-PAS) revealed generation possibly toxic byproducts such aromatic compounds. This seems to indicate could not be regarded suitable for cavitation.

Enhancing Methane Oxidation in Landfill Cover Using Brewery Spent Grain as Biocover
Landfill gas (LFG) is a potent greenhouse gas (GHG) generated by anaerobic degradation of decomposable municipal solid wastes (MSW). LFG contains (50-60%) of methane (CH4) and (40–50%) carbon dioxide (CO2). If a landfill is neither aerated nor equipped with gas capture systems, the LFG emissions, mainly CH4, in the cover soil is best reduced by using a biocover. Biocovers normally act as a biof...
متن کاملOzonation as polishing treatment of mature landfill leachate.
Mature landfill leachate is typically resistant to biological processes. In order to enhance the biodegradability of a pre-treated mature landfill leachate, ozonation treatments in a lab-scale column were assayed under different ozone concentrations, contact time, initial pH, and hydrogen peroxide concentrations. Degradation of the landfill leachate by ozone was favoured at higher pH values and...

Fenton treatment (Fe(2+)/H(2)O(2)) and different ozone-based Advanced Oxidation Processes (AOPs) (O(3), O(3)/OH(-) and O(3)/H(2)O(2)) were evaluated as pre-treatment of a mature landfill leachate, in order to improve the biodegradability of its recalcitrant organic matter for subsequent biological treatment. With a two-fold diluted leachate, at optimised experimental conditions (initial pH 3, H...

The research was on the sludge start-up of SH-A process for mature landfill leachate treatment, SH-A is the combined SHARON (Single Reactor High Activity Ammonia Removal Over Nitrite) ANAMMOX(Anaerobic Ammonium Oxidation). The seed sludge was from Yangeryu Landfill of Anshan, Liaoning province of China. The landfill leachate was used to cultivate the sludge. The results showed that the start-up...
متن کاملTreatment of mature landfill leachate by chemical precipitation and Fenton advanced oxidation process
Background: Mature landfill leachate is a complicated mixture which is resistant to biological treatment processes. The treatment of mature landfill leachate by struvite precipitation and Fenton oxidation was the main objective of the current research. Methods: Struvite with the phosphate/ammonia/magnesium molar ratio of 1/1/1.05 was considered during all experiments. Five initial pHs of 3, 4,...
