Kiselalgsanalys eller Kvävefosforanalys? Av: Anders Andersson 2017 Övergödning är ett växande problem som anses vara den främsta orsaken till försämring av vattenkvaliteten i vattendrag. För att studera vattenkvaliteten finns olika metoder, kiselalgernas egenskap som påväxtalger innebär att de inte kan flytta på sig. De antingen måste anpassa sig eller försvinna när förändringar sker i vattnet. IdEutrophication is one of the most threatening issues to water quality in natural water. It can cause problems of the ecosystem, with for example, lowering the biodiversity of the community. The main reason for eutrophication in natural waters is the leakage of nutrients from nearby crop-fields. Too much of nutrients reaches the water and negatively interferes with the water community. To study the

En bättre process för mindre miljöpåverkan ​ Människors miljöpåverkan har genom historien varit stor, men de senaste åren har miljömedvetenhet bland allmänheten och företagen ökat. Processer för att rena utsläpp har blivit allt viktigare och har en given plats i dagens fabriker. I denna artikel har en sådan process utvärderats och förbättrats. För människor, djur och natur är vatten livsviktigt,Stora Enso Nymölla Mill is an integrated pulp and paper mill located in south Sweden near the Baltic Sea. The mill uses ultrafiltration (UF) to remove compounds with a high chemical oxygen demand (COD) from the bleach plant effluent. UF is a separation technology using membranes. There is no phase change during the separation, which makes UF less energy demanding than other separation processes. U

Kollektivtrafiken är ett viktigt verktyg för att minska växthusgasutsläppen inom transportsektorn och uppnåendet av ett hållbart transportsystem. Utöver detta kan kollektivtrafiken även bidra till den regionala utvecklingen, samt att öka stadens attraktivitet och människornas livskvalitet i staden. Av kollektivtrafikslagen är det främst spårvägen som väckt stort intresse under de senaste åren. DetThe aim of the study is to show how the aspect of climate change, relative to the three dimensions of sustainable development, is addressed in municipal plans for light rail.
