Vattenverket Görväln i Järfälla planerar ett nytt vattenverk i framtiden, lokaliserat intill nuvarande vattenverk. Idag är den kemiska barriären, granulerat aktivt kol, ur funktion och utvärderas i det här projektet för att effektivisera processen. Den här studien fokuserar på att optimera den kemiska barriären genom att jämföra två sorter av granulerat aktivt kol (GAC). Jämförelsen sker genom analysering av löst organiskt kol (DOC), totalt organiskt kol (TOC), samt absorbans och fluorescens. Vattnet som använts i studien kommer direkt från det sandfiltrerade vattnet i Görvälnverkets reningspr

Gac (Momordica Cochinchinensis Spreng or Muricia Cochinchinensis Spreng) is an indigenous fruit of Vietnam, commonly used as a colourant in traditional dishes. Recent studies showed that this fruit had a high carotenoid content, especially lycopene and β-carotene. These carotenoids are currently in high demand as they are natural antioxidants to prevent and treat cancers. Over the last ten years some new products from Gac fruit have been found on the market but the cultivation and consumption of the fruit is still limited. Gac is harvested seasonally and the post harvest processing has not bee

Fenton-dependent recovery of carbon initially saturated with one of several chlorinated aliphatic contaminants was studied in batch and continuous-flow reactors. A specialty carbon, URV-MOD 1 (Calgon) was employed to minimize non-productive H2O2 demand - that which does not yield hydroxyl or superoxide radicals.Enhancement of PCE degradation kinetics by ferric iron addition is limited by iron solubility, even at relatively low pH. Quinone addition increased the pseudo-first-order rate constant for PCE loss temporarily. Only copper addition sustainably enhanced the specific rate of PCE loss.

The treatment of potable water in Vars, ON is accomplished by filtering the colored, iron-laden groundwater through granular activated carbon (GAC) filters. When first installed, these filters unexpectedly experienced chromatographic displacements of iron into the produced water which resulted in orange-brown water at consumers’ taps. The treatment plant was later modified by adding potassium permanganate oxidation and a greensand filter prior to the GAC adsorption columns. Consequently, iron was almost completely removed and no longer caused operational problems. The main objective of this di

Per- and polyfluoroalkyl substances (PFASs) are a group of artificial chemicals which have been used in a wide area of applications such as surface protection agents in cloths and different industrial applications. It has been found that PFASs are potentially toxic and are frequently found in the environment due to their persistent and mobile properties. Effluents from wastewater treatment plants (WWTPs) have been identified as an important point source of PFASs. Bark, by-product from the paper and wood industry, is a low-cost adsorbent and has the potential to be used as a filter material for

Une nouvelle classe de capteurs de gaz innovants basée sur des transistors à haute mobilité électronique (HEMT) AlGaN/GaN a été développée pour les applications géologiques. Elle est conçue dans le but d'étudier le transfert de masse des gaz (H2, CO2, CH4, O2, H2S, SO2 et He) entre le sous-sol et l'atmosphère sur de grandes étendues géographiques. Pour cela, elle intègre les caractéristiques clé suivantes : la miniaturisation, la robustesse, l'insensibilité aux environnements difficiles associées à un coût contenu.

Lorsque le galeriste new-yorkais John Gibson, figure en pointe de la scène américaine des années 1960-1970, organisa les expositions Story I (1973) et Narrative II (1974), il avait perçu ce qui serait « le prochain truc » en vogue après l'Ecologic art et le Body art : la narrativité. Si le Narrative art est tombé dans l'oubli, cette perception qui reposait sur un noyau dur d'artistes américains et européens (Le Gac, Bay, Baldessari, Wegman, Askevold, Hutchinson, Beckley, Welch. . . ) préoccupés par des problématiques narratives aux moyens de la photographie et du texte fut confirmée par une pé

The J-laying technique for the construction of offshore pipelines requires a fast welding process that can produce sound welds in the horizontal-vertical position. The suitability of narrow gap gas metal arc welding (NG-GMA W) process for this application was previously demonstrated. The present programme studied the influence of process parameters on the fusion characteristics of NG-GMA welding in a range of different shielding gas compositions and welding positions. Statistical techniques were employed for both designing the experimental programme and to process the data generated. A partial

Suspended fly-ash particles in industrial emission gasses have a major degrading effect on the whole environment. Electrostatic precipitation is one of the oldest and most effective gas-cleaning processes used today. Electrostatic precipitators use electrostatic forces to clean the flue gas of ash particles. Stricter emission control laws force industries (like SASOL) to improve their electrostatic precipitators. This study consists of a comprehensive literature survey and the development of a numerical fluid flow model. The proper flow of the gas through an electrostatic precipitator is one o

With the help of nitridation of porous GaP (001) in nitrogen plasma thin films of cubic-GaN were obtained. The conclusion was made that the quality of the GaN films is dependent on the degree of porosity of the GaP substrate. XPS spectra were used to investigate the chemical composition of porous GaP substrates, obtained by electrochemical etching. From XPS measurement we determined that the annealing in atomic nitrogen leads to the formation of GaN films. X-ray diffraction measurements show that cubic GaN on porous GaP substrate has no tensile strain When you are citing the document, use

Gac (Momordica Cochinchinensis Spreng or Muricia Cochinchinensis Spreng) is an indigenous fruit of Vietnam, commonly used as a colourant in traditional dishes. Recent studies showed that this fruit had a high carotenoid content, especially lycopene and β-carotene. These carotenoids are currently in high demand as they are natural antioxidants to prevent and treat cancers. Over the last ten years some new products from Gac fruit have been found on the market but the cultivation and consumption of the fruit is still limited. Gac is harvested seasonally and the post harvest processing has not bee
