Excerpts from the Paper

The beginning:
Resources and Waste Management
1.
2. a) pop cans:
Pop cans are mostly made of aluminium. Aluminium is a non-renewable resource and pop cans that find their way into a landfill take up space and waste a potentially recyclable material. The cans take up a lot of space simply because of their size and shape. Pop cans also present a potential danger in landfill, since aluminium can be dissolved in acid water, and the
leachete
in landfill is usually acid. In this way, the aluminium can be carried into underground water or into rivers and lakes, where fish and other aquatic organisms can ingest it (
Guterman
, 1998). People can also be potentially exposed to water high in aluminium levels. There is some evidence linking aluminium water pollution...

.....processes, mainly gravitational settling and skimming. The water is then pumped into the secondary treatment where
microorganisms
are used in aeration tanks to degrade organic material. As the water enters the aeration tank, ferrous chloride is added to remove phosphorus, which settles at the bottom. The water then flows to the secondary clarifiers where activated sludge settles at the bottom. Sodium hypochlorite is added at the beginning of the outfall for disinfection. Sodium bisulphate is added towards the end of the outfall for de-chlorination. The total daily capacity of the plant is 448,000 cubic metres of wastewater (Region of Peel).
