    Råstorps avloppsnät: Förslag till ombyggnad av avloppssystemet i Råstorp2012Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Rapporten handlar om ett vakuumsystem i Råstorp som är i behov av att bytas ut inom de närmaste åren.Med hjälp av personalen på Va-verket i Markaryd har jag fått en bild av hur det fungerar idag. Det finns en del problem med service och reservdelar, men framförallt så går det inte att lita på att systemet fungerar.Jag har mätt ut befintliga höjder, både markhöjd och vattengång vid de brunnar som finns. Av detta har jag sedan, bland annat, gjort beräkningar på självfallssystem. Därefter har jag kommit fram till att ett kombinerat system, självfallsledningar och tryckavloppssystem skulle kunna var en lösning.

    Degradation of a textile azo dye using biological treatment followed by photo-Fenton oxidation: evaluation of toxicity and microbial community structure2015Inngår i: Chemical Engineering Journal, ISSN 1385-8947, E-ISSN 1873-3212, Vol. 270, 290-299 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Many commercial dye preparations are cocktails of active dyes and various by-products that are recalcitrant to biological degradation and end up in significant amounts in the effluent after the dyeing process. Conventional wastewater treatment processes are not able to degrade such compounds and detoxify the effluent, thus alternative treatments should be developed.

    In our work we suggest to use photo-Fenton oxidation as post-treatment after an anaerobic biofilm process, in a way to minimize the reagents needed. This process was used for treatment of synthetic textile wastewater containing the commercial azo dyestuff Remazol Red, starch and sodium chloride. The treated textile effluent had COD lower than 18 mg/l even when using initial Fenton reagents concentration as low as 1 mM ferrous ions and 10 mM hydrogen peroxide. The acute toxicity was higher in the biologically treated than in the untreated effluent. Photo-Fenton oxidation successfully reduced the toxicity and the final effluent was non-toxic to Artemia salina and Microtox, with the exception of the effluent containing high concentration of sodium chloride, which was moderately toxic to Microtox. For the first time the presence of algae was detected in a reactor treating textile wastewater using denaturing gradient gel electrophoresis (DGGE); bacteria and fungi were also abundant.

    The results of this study suggest that using advanced oxidation after biological treatment is an effective way to degrade the organic compounds and remove toxicity from textile effluents.

    Evaluation of filter material for treatment of different types of wastewater2011Inngår i: Journal of Environmental Protection, ISSN 2152-2197, E-ISSN 2152-2219, Vol. 2, nr 7, 888-894 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper presents an evaluation of the suitability of a mixed absorbent based on peat and carbon-containing ash for treatment of wastewaters, such as wastewater from professional car washes, landfill leachate and stormwater. This mixture is very attractive, since it is a low-cost material which has a capability to simultaneously remove inorganic as well as organic pollutants. Since any filter material eventually needs to be replaced either due to saturation of pollutants or reduced infiltration capacity, it is important that the residual can be handled at low cost and that the environment will be not impaired. The tested mixture, used in filter beds, showed low leaching values and high simultaneous removal efficiency of metals as Cu, Cd and Pb, non-polar organic compounds such as PCBs. Polar organic compounds as phenols were also efficiently removed by microbial and/or chemical degradation in the studied treatment plants with the filter bed acted as a biofilter. Filter material used for three years in a full-scale plant for leachate treatment and four years in treatment plants for wastewater from car washes, had sufficiently high energy content indicating that energy recovery is a good alternative for handling after its usage. Results show that the presented filter material is excellent for both small scale applications (e.g. treatment systems for car wash wastewater with capacity between 250 - 3000 m3 per year) as well as large-scale applications (e.g. filter systems for landfill leachates with capacity above 30,000 m3 per year).

    Treatment of wood leachate with high polyphenols content by peat and carbon-containing fly ash filters2015Inngår i: Desalination and Water Treatment, ISSN 1944-3994, E-ISSN 1944-3986, Vol. 53, nr 8, 2041-2048 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In the present study, two combinations of filter materials in filter/columns were examined for removal of total organic carbon (TOC) and polyphenols (PP) found in storm water runoff from wood storage areas in a wooden floor industry. One filter/column was packed with peat mixed with carbon-containing fly ash, while another filter/column contained only peat (without ash). The mixture of peat and ash has shown faster and higher removal capacity for TOC and faster removal with the same final removal capacity for PP (in grams of pollutant per kg of sorbent) at the saturation point. The superiority observed for the peat and ash filter is presumably due to the unique characteristics of peat and ash, which enhanced the treatment efficiency when used together in a mixture. Based on the observed results, filters formed by peat and carbon-containing ashes proved to be a potentially low-cost option for the treatment of storm water generated at storage areas of wood materials such as logs, sawdust and wood chips.

    Investigation of Hard Biodegradable Pharmaceuticals Pollutants Treatment of Hospital Wastewaters2014Inngår i: Book of abstracts, 2014, 173- s.Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    According to the results of the research performed in the different modern research laboratories the remnants of drugs and their derivatives are found in surface waters in France, USA, UK, Germany, Denmark and Sweden. These substances also can be found in sewage sludge, river and ocean sediments and in the municipal landfills filtrates. Some species have been found even in drinking water and ice, grou nd and ocean waters. Many studies confirmed the data of the annual drug releasing into the environment, which counts several hundred of kilograms. Thus, the investigations of negative impact of pharmaceutical substances and their derivatives on aquatic organisms have been performed  during more  than 20 years and showed an extremely negative presence of any drugs in the waters. Now, they are still  considering  as  emerging organic contaminants in the different type of waters. The main sources of water pollution by pharmaceuticals and their derivatives are wastewater from hospitals, clinics, pharmaceutical industries and domestic sewage as well. However, the main percentage of pharmaceuticals dumped into wastewaters is coming from the hospitals. This is typical for large cities, where is situated a great n um ber of hospitals and health care institutions. In the opinion of one study hospital wastewaters have been found in a 15 times higher potential ecotoxicity than the general urban have. The negative effect of pharmaceuticals influence into environment can be decrease due to application of different kinds of additional wastewater treatment as Advanced Oxidation Processes (AOPs). The main approaches of hospitals wastewater treatment in Ukraine and Sweden by implementation of AOPs method were considered in this study. The main data of this research will be presented.
