Watercycle
State the 6 stages of the water cycle
Evaporation, transpiration, condensation, sublimation, precipitation, runoff, infiltration
Where does plastic pollution occur?
In oceans, rivers, lakes and water bodies.
What are some impacts of the plastic pollution?
Environmental, Social and Economic impacts.
What percent of microplastics can be eliminated using banana pulps through biofilters?
Banana pulp filters can eliminate up to 98.5% of microplastics in the wastewater
Biofilters are devices that purify contaminated water by using what?
Microorganisms and natural materials
What happens to the water which comes down as rain?
The rain water flows down to lake, rivers, pond, and ocean. Some is taken by the soil and it goes down the ground.
How metric tons of plastic waste enters water bodies in a year?
8 to 12 million
What are the chemicals that can be found in plastic pollution?
Plasticizers, UV absorbers, flame retardants.
Biofilters efficiently removes pollutants from water by using what biological organisms?
Bacteria, plants, and algae
How effective is biofilters effective at eliminating contaminants?
Biofilters are a suitable choice for purifying wastewater since they are effective at eliminating 95-99% of contaminants
How does plastic pollution affects the water cycle?
Plastic pollution disrupts heat, evaporation, weather, and ecosystems, unbalancing the water cycle.
How does plastic find its way into waterbodies and ocean?
How does plastic pollution impact marine animals?
Ingestion, Entanglement, Ecosystems Disruption
What are the good factors about biofilters?
It's affordable, less chemicals, function well at room temperature, and can be used for variety of wastewater treatment.
What happens when the wastewater goes through the biofilters?
These contaminants then get broken down through the microbes into less dangerous compounds like water or carbon dioxide.
