Utvärdering av kapaciteten hos en två-stegs UASB-reaktor för behandling av hushållsavloppsvatten
… reactors are usually operated at 37°C. It is possible to attain a high COD-reduction at lower temperatures, assumed a longer contact time between biomass and waste water. In an Upflow Anaerobic Sludge Blanket (UASB) - reactor the microorganisms form granules with excellent …
… monoxide have been detected in the water from the scrubber. This proves that a reduction of these harmful emissions takes place. Unfortunately no evaluation could be made concerning how good the reduction really was. The cost of the prototype facility was 60 000 SEK, a possible …
… as encoding to a Boolean domain and performing the optimisations. The variable reduction heuristic is based on finding sub-circuits that are suitable for reduction and a state space search is performed on those groups. An evaluation of the results shows that in some cases the …
En undersökning av reningseffekt med avseende på järn och mangan
… were tested. The manganese was very easy to oxidize andno difference in the reduction of manganese content in the water between the different filterswas observed. The iron was on the other hand very difficult to oxidize and no reduction of theiron content was obtained even …
… flow of urea to the lances that is studied in this work. Some literature about reduction of nitrogen oxides is studied, especially reduction using urea injection. There are a lot of factors that affect how good the reduction becomes. The most important factors are the amount of …
påverkande faktorer och metodik för statistisk modellering
… a multiple regression analysis was performed. This analysis examined how the reduction of lead, copper, zinc and cadmium depends on the following factors: the specific pond area, the variance of the residence time distribution, the hydraulic efficiency and the concentration of …
Med inriktning mot hållfasthet och dämpning av ljud
… with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it …
… was also when the lake was lowered. This occurred in tages. The first reduction took place in the 1790s and it continued with several reduction experiments during the early 1800s decades, which unfortunately failed. The large reduction was implemented during 1866-69 and by that …
en jämförande pilotstudie
… 30 tumors treated with Aldara? 27 tumors (90%) has so far responded with size reduction or total regression. The 3 tumors that didn´t respond to treatment were all fibroblastic sarcoids localized to the distal limbs on one horse. Of the 15 tumors treated with Xxterra? 14 tumors …
En konsekvensstudie av ett slopande av aktiekapitalkravet
… appointed a commission of inquiry with the task to submit a proposal of reduction in the requirement of a minimum legal capital for private limited liability companies. The commission of inquiry’s main proposal involved a reduction to SEK 50,000 compared to the prevailing SEK …
- samt hur fasad och fönster dimensioneras med uppmätta värden
… The level 85-89 dB(A) also shows a small variation. Calculations of the sound reduction index (R'w) for facade elements were also carried out for all the schools. The resulting sound reduction index for the whole facade was 34-41 dB. After assuming a 200 mm thick concrete facade …
… in other management proposals. On average, poor data quality resulted in a reduction of net present value of 1 891 SEK / ha, while the management proposals set out in the forest plan generated a reduction of 637 SEK / ha, but then only for the first ten years. The difference in …
… fertilizer demand over the fields are factorsthat among others affect the reduction in leaching, and were therefore accounted for in thecalculations. The results showed that the reduction in leaching by using site-specific Nfertilization,with an average optimum rate of 100 kg …
… monohydrochloride withlysine. Ingredients that indicated moderate bitterness reduction were aspartic acid andglutamic acid, both giving sour solutions but the latter being regarded as unpalatable.Ingredients indicated to reduce bitterness a little were carbonic acid …
: SKILLNADER VID STYRKETEST I BÄNKPRESS OCH LIGGANDE BÄNKRODD MED SKIVSTÄNGER AV OLIKA DIAMETEROMFÅNG
… sizes. Results: The results from the present investigation indicates a 21,1 % reduction of 80 % of 1 RM weight performance in repetitions executed in the bench press with the thicker diameter of the bar and a 66,2 % reduction in repetitions executed with a 80 % of 1 RM weight in …
