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