This study proposes a multi-objective optimisation methodology to investigate sustainable network designs for solid waste management system. A case of Pathum Thani province, Thailand, is used to illustrate the application of the methodology. The social impact, defined as the number of people affected by the unpleasant sanitary conditions of nearby solid waste management facilities, is estimated by using GIS tools. The sustainability performances are normalised to a satisfaction scale, allowing decision makers to select network design solutions based on their sustainability target preferences. The results suggest that the facility location can significantly alter the sustainability performances, and it is shown that the locations of waste management facilities can be arranged to simultaneously improve all of the aspects of sustainability.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2017-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42411580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs struvite precipitation to control ammonia accumulation, and focuses on the efficacy of ammonia removal under neutral reaction conditions (pH = 7). The impacts of phosphate and magnesium additives, pH, temperature and the N:Mg:P molar ratio are quantified. Magnesium chloride (MgCl2 • 6H2O) and monopotassium phosphate (KH2PO4) are shown to be the most efficient combination of additives for total ammoniacal nitrogen (TAN) reduction of poultry manure leachate under neutral reaction conditions (pH = 7), demonstrating a TAN reduction of 90.3%. Modification of molar ratios (NH4:Mg:PO4) evidenced no significant benefit with regard to TAN reduction. However, increasing the fraction of supplementary magnesium resulted in a statistically significant (p < 0.05) decrease in phosphate concentration within the leachate. This study demonstrates the advantages of struvite precipitation, as a method of ammonia control, to improve anaerobic digestion and hence management of poultry manure. Although an effective means of TAN control, struvite precipitation from poultry manure is an ineffective means of obtaining pure struvite due to the formation of co-precipitates.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2017-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45573428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study utilises photosynthetic acclimation rates and morphological measurements to gauge cadmium toxicity in radish plants raised on nutrient solutions containing 0, 5, 10 and 20 µM CdCl2. Growth rates displayed a dose-dependent decline with cadmium exposure. Photosynthetic acclimation was significantly reduced compared to controls in all cadmium treatments. Inductively coupled plasma mass spectrometry was used to determine cadmium accumulation. In both the roots and shoots of the plant, cadmium levels were significantly higher than the controls in 10 and 20 µM treatments. Significantly more cadmium was distributed into the roots compared to shoots. A moderate tolerance for and reasonable accumulation of cadmium makes the radish a candidate for phytoremediation in marginally contaminated environments. Furthermore, the sensitivity of photosynthetic acclimation rates to cadmium exposure serves as a potential bioindicator of cadmium contamination.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2017-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47501816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to WHO, the MCL for As and Pb is 0.01 mg/L. From the results obtained, about 75% of biota samples analysed contained As and Pb in concentrations above MCL. The subject of health concern is the increasing concentration of As in Modinagar and Meerut residential area. The effluents from industries, pesticides used in agriculture land and improper waste management are the reasons responsible for heavy metal toxicity in this belt.

The dried and acid-alkali treated bulbs of water hyacinth (WHB) having high porosity and O2-filled functional groups were utilised to treat Pb(II) from industrial wastewater. Characterisation of WHB with FESEM, XRD and FTIR exhibited the presence of several carboxyls, hydroxyl, ketonic, aldehydes and other O2-filled functional groups showing WHB adsorption with highest monolayer capacity of (Qm) 38.614 mg/g. WHB adsorption directed towards the pseudo-second order kinetics and Langmuir isotherm mechanism. The study also emphasised effective regeneration of WHB using HNO3, NaOH and vacuum dry. The bio-sorption mechanism was observed to be endothermic spontaneous reaction process, with ΔG decreased from -0.71 to -8.53 with increasing temperature. With optimised and controlled process conditions, only 5.0 g L−1 of WHB bio-sorbent could significantly treat about 85.3% of 100 mg L−1 of Pb(II) within 120 minutes at pH 7.0 and 30°C. Also a comparative optimisation study of ANN and RSM were used to predict the WHB bio-sorption bioprocess. Therefore, WHB have efficient potential to be commercially applicable as an environmental-friendly and economical bio-sorbent for treatment of Pb(II) from solutions and effluent from paint industry.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2017-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46343098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Actinobacteria, the most important groups of microbes, are responsible for degradation and transformation of organic and metal substrates and also possess significant bioremediation potential. It can degrade high doses of pesticides, chemical complexes, and heavy metals.
