Swine waste generated from pig-domesticating
industry is considered a primary source for fresh water
pollution. Although many treatment systems have been
investigated, the effluents are still high in of inorganic
compounds, which cause deterioration of water resources.
These compounds are also important nutrient sources for
aquatic plants and specially algae (Finlayson et al., 1987;
Tiow-Suan & Anthony, 1988; Sevrin-Reyssac, 1998). Algae
use solar energy, while absorbing nutrients from wastewater
to fix carbon substances to produce plant biomass that
would constitute a valuable source of compounds for
animal feeding supplement and that can be at the same time,
as a decaying organic pollutant that decreases water
pollution.
