HEAVY METALS REMOVAL IN ANIMAL WASTEWATER USING .
The term 'heavy metal' has become wellestablished in the literature of environmental pollution. In constructed wetlands, plants act as a 'polishing system' in removal of heavy metals from contaminated water (Matagi et al., 1998). Examples of heavy metals include zinc (Zn), cadmium (Cd), copper (Cu) and lead (Pb).

Five reasons why aluminum piping makes sense for ...
· Copper piping is another solution for compressed air systems and is attractive because it doesn't corrode as much as steel pipe. While it can corrode, it doesn't have pipe scaling like steel pipe. This means that a copper system will have fewer air flow problems and air cleanliness problems than steel pipe, but it can still experience flow restriction over time.
