Algae

Laboratory experiments were carried out to investigate electrocoagulation as electrodisinfection of artificial wastewater contaminated by no pathogenic Escherichia coli species in batch culture and two surface waters using three different electrodes. Aluminium electrodes were found most efficient in

Slow sand filtration is a biological means of surface water clarification that involves both biological and physical mechanisms. During this process, as time progresses, microbiological growth occurs, mainly consisting of micro-algae and bacteria which form a fixed microbial ecosystem (biofilm) on t

For long-term space missions, the algae Arthrospira platensis (previously Spirulina platensis) can be used as a food component. A. platensis can be cultured in a Zarrouk medium (further called “medium”) which contains several salts. As a result, the cultured cells have to be washed to make them edib
