Which microalgae is used for wastewater treatment?
A number of studies have reported successful cultivation of several species of microalgae such as Chlorella, Scenedesmus, Phormidium, Botryococcus, Chlamydomonas, and Arthrospira for wastewater treatment and the efficacy of this method is promising (Olguì, 2003; Chinnasamy et al., 2010; Kong et al., 2010; Stephens et …
Why algae is used in wastewater treatment?
Algae benefit wastewater treatment by producing oxygen that allows aerobic bacteria to breakdown organic contaminants in the water and taking up excess nitrogen and phosphorus in the process. It is also a sustainable and affordable alternative to current wastewater treatment practices.
Which algae can be grown on wastewater?
Algae biomass production potential from wastewater resources This study was conducted to assess the potential of cultivating algae using wastewater as a nutrient medium. The consortium of algal species, including Scenedesmus sp. and Chlorella sp. grew favorably on anaerobic sludge centrate from the HFC AWTP.
Can microalgae remove pharmaceutical contaminants from water?
Those tolerant microalgae species have been used to treat municipal wastewater, anaerobic digestion effluent, textile dye wastewater, agro-industrial wastewater, metal-containing wastewater, industrial effluent, sugar mill effluent, and various pharmaceutical contaminants in various algal bioreactors and high rate …
Why does algae cause water pollution?
Elevated nutrient levels and algal blooms can also cause problems in drinking water in communities nearby and upstream from dead zones. Harmful algal blooms release toxins that contaminate drinking water, causing illnesses for animals and humans.
How does algae affect water quality?
Why is microalgae important to life?
Microalgae, capable of performing photosynthesis, are important for life on earth; they produce approximately half of the atmospheric oxygen and use simultaneously the greenhouse gas carbon dioxide to grow photoautotrophically.
What is the difference between algae and microalgae?
The main difference between algae and microalgae is that algae are simple, autotrophic organisms, consisting of a huge diversity among them whereas microalgae are the microscopic type of algae.
What is the effect of algae in water?
Algal blooms can reduce the ability of fish and other aquatic life to find food and can cause entire populations to leave an area or even die. Harmful algal blooms cause thick, green muck that impacts clear water, recreation, businesses and property values.
Why is algae an indicator of pollution?
Algae are valuable indicators of ecosystem conditions because they respond quickly both in species composition and densities to a wide range of water conditions due to changes in water chemistry.
