After being sterilized, water is then let back out into the ocean, or commons. In the lab, the clean water was put down the sink.

Bleach is poured into the left over water to clean and sterilize it, further making it safe for discharge, which is comparable in real life cleaning systems, chlorine or uv light is used to kill any left over bacteria.

Organisms are placed in the water, and eat what they need to, causing the left over particles to turn into solid clumps and sink, and are then removed as secondary sludge and used as fertilizer

# data[].attributes.body
Much like real life water is left to sit and the left over particles sink to the bottom and removed as secondary sludge, and put in a sludge tank or dried out. The water is then moved on to disinfection areas

# data[].attributes.body
Bacteria and other fine living organisms are placed in the water to eat up the particles the human eye can not see that can be harmful to other organisms. Carbon, nitrogen, and phosphorus are removed.

The mixture of sand and fine particles were added, mixed, settled, and then poured into the secondary settling tank

# data[].attributes.body
The wastewater is slowly moved along, allowing the oils and lighter objects to rise to the top and the heavier solids to move to the bottom and then scraped off using automatic scrapers

# data[].attributes.body
During primary settling, the wastewater sat in order to let the lighter particles (oil and tea leaves) float to the top, later to be removed by an absorbent scooper. At the bottom, the settling is called sludge and is removed later and put in the sludge tank.

Following the screening process, water slows down and is spun in order for the stones and objects like that to be removed and not damages the systems. Post-removal, the stones are buried in a land fill

# data[].attributes.body
We spun the wastewater to see what would be left at the bottom and as we spun we observed the objects that sank to the bottom (sludge). We then proceeded to take the mixture and pour it into the beaker labeled “primary settling”

# data[].attributes.body
Wastewater passes through metal bars to remove large objects that should not have been flushed such as bags, papers and rags to avoid damaging the cleaning objects in the process of working towards discharging. The large objects are removed and placed in a landfill.

# data[].attributes.body
We placed a piece of plastic mesh on top of the beaker labeled “grit chamber) and used the mesh to catch the large soldis (rocks)

# data[].attributes.body
In real life, wastewater is collected and cleaned to dispose of dangerous chemicals that threaten animals (humans included), and to protect the systems that make actually make the water dischargabale

# data[].attributes.body
In the lab, the wastewater we made consisted of water (water compound), tea and crushed leaves (fine human solids), cut up tea bags (large objects), small stones (grit), cooking oil ( oils), and sugar (dissolved nutrients).
