Waste water treatment is the process of removing
existing contaminants to make water becomes fit for disposal or
reuse. The waste water generally contains 99.9% water and
0.1% of solid impurities; thus, it has a large potential as a
source of water for different purposes such as fish ponds,
comfort rooms, cleaning source, among others. Treated water
can be used back into the natural environment without adverse
ecological impact. In the Philippines, the most commonly used
treatment methods for beverage companies are pond/lagoon
system and activated sludge system.
