Several parameters such as pH, contact time, agitation speed, temperature, initial dye concentration, and adsorbent dosage were considered and their impact on dye adsorption efficiency was evaluated. The removal percentages of ENB dye due to adsorption on banana peel and sugarcane bagasse were 72% and 70%, respectively. Simultaneous dosing of both biosorbents resulted in 68% dye removal. The Langmuir isotherm model was found to fit the adsorption of ENB dye on banana peel and sugarcane bagasse powders. The corresponding maximum adsorption capacities were equal to 24.09, 32.46, and 27.54 mg/g for banana peel powder, sugarcane bagasse powder, and the mixture of adsorbents, respectively.","PeriodicalId":11709,"journal":{"name":"Environment Protection Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70006002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Emphasis is on applications of seawater scrubbing of ship’s power plant exhaust gas containing SO2. The formulated model is used to predict the influence of various parameters on both pH of tailwater and seawater desulfurization capability, e.g., the partial pressure of SO2, the partial pressure of CO2, tailwater temperature, pH and alkalinity of seawater. Experiment results indicated that the seawater desulfurization capacity increases with both increasing partial pressure of SO2, pH and alkalinity and decreasing partial pressure of CO2 and temperature. The study shows the desulfurization capacity of seawater with 3.5% salinity is approximately twice that of freshwater. Different scenarios in which the required absorbent supply rate for a given SO2 removal efficiency are studied. It is observed a 97% removal efficiency, corresponding to meeting the SOx limits in the SOx emission control areas (SECA) while operating on a heavy fuel oil containing sulfur 3.5 wt. %, requires a minimum water supply rate of 0.0407–0.0683 m3/kWh, depending mainly on the water composition in terms of alkalinity and salinity. Such data are important in assessing the operation cost of the water scrubbing system.","PeriodicalId":11709,"journal":{"name":"Environment Protection Engineering","volume":"46 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70005728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This phenomenon causes both reversible and irreversible flow resistances that can be minimized with comple-mentary techniques such as sonication and/or stirring. The application of ultrasonic energy can increase the flux by breaking the concentration polarization and cake layer on the membrane surface without affecting the intrinsic permeability of the membrane. Our work focused on cellulase and β -glucosidase enzyme recovery through sonicated/stirred ultrafiltration from the real fermentation broth, at which the fermentation liquid was produced from tobacco plants. Membrane filtrations were carried out in a la-boratory-grade batch ultrafiltration cell, extended with stirrer and ultrasound processor. The effects of stirring speed and ultrasound treatment were investigated on the membrane’s permeate flux efficiency and on the quality of recycled enzymes. Resistance values were calculated by the resistance-in-series model, as well as by Hermia’s analysis, to reveal deeper, process-related information. Our results re-vealed that enzymes could be efficiently separated from real fermentation broth. Furthermore, the enzyme activity test showed that neither stirred nor sonicated processes were detrimental to the enzyme activity.","PeriodicalId":11709,"journal":{"name":"Environment Protection Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70005744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The estimation of SVI and MLSS has been proposed using image analysis based modeling which is time-efficient and valid for multiple plants operating in different states. The methodology includes the sequence of image acquisition using bright-field microscopy, a robust segmentation of flocs, partitioning of flocs based on different ranges of their equivalent diameters, extraction of morphological features, and modeling of SVI and MLSS using the features. It is proposed that bright-field microscopy at lower magnification to capture the flocs is sufficient to model SVI and MLSS. A robust approach for image segmentation is adopted by integrating state-of-the-art image segmentation algorithms. It is hypothesized that flocs in different ranges of equivalent diameter respond differently to the variation in the operating state. Hence, flocs and their respective image analysis features are categorized based on the range of equivalent diameter. Finally, stepwise regression is used for feature selection and model identification to explore the feasibility of generalization of models to multiple plants in different states regarding SVI and MLSS.","PeriodicalId":11709,"journal":{"name":"Environment Protection Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70005872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
