Design parameters of high rate algal ponds using filamentous algae matrix for treating rural stream water.

Focuses on high rate algal ponds (HRAP) with a filamentous algae matrix (FAM) as the predominant species, which were operated to evaluate the characteristics of FAM and the basic design parameters for treating polluted rural stream water. How the porous and gelatinous FAM was formed like a sponge, which functions to prevent excessive loss of the algae in the effluent and can easily be retrieved from the ponds.
