Primary treatment involves filtering out as much of the solid waste as possible through a Nitrogenaerateddenitrificationfiltrationorganicphosphatesscreensedimentswater.
The water is then let then sit in a number of ponds or pools where the Nitrogenaerateddenitrificationfiltrationorganicphosphatesscreensedimentswater in the water can settle to the bottom.
About half of the solid waste, bacteria and Nitrogenaerateddenitrificationfiltrationorganicphosphatesscreensedimentswater material can be removed in this way.
In the secondary stage of treatment, use is made of Nitrogenaerateddenitrificationfiltrationorganicphosphatesscreensedimentswater tanks where bacteria can consume much of the remaining organic matter and nutrients in the water.
By now, about 90 percent of the waste in the Nitrogenaerateddenitrificationfiltrationorganicphosphatesscreensedimentswater has been removed.
Tertiary treatment removes nitrates and Nitrogenaerateddenitrificationfiltrationorganicphosphatesscreensedimentswater.
Aluminium sulfate is added which causes the phosphates to precipitate out, and they are then removed by Nitrogenaerateddenitrificationfiltrationorganicphosphatesscreensedimentswater.
Nitrogen is removed by Nitrogenaerateddenitrificationfiltrationorganicphosphatesscreensedimentswater, the reduction of nitrate to nitrogen gas.
Nitrogenaerateddenitrificationfiltrationorganicphosphatesscreensedimentswater gas is released to the atmosphere and thus removed from the water.
