Abstract |
Growing popularity of waste stabilization ponds has created new interest in the pond mechanism and factors affecting it. Mode of action and impact of these factors influence design and resulting pond accomplishment. Of importance are photosynthetic oxygenation; interrelation of light penetration, algal density, and depth; the effect of temperature upon B.O.D. rate, D.O. saturation level, and photosynthesis; and the manner in which seasonal forces are superimposed upon daily fluctuation in pond characteristics. The relative influences of ice cover and loading pattern and the responses that follow are pointed out. (Author) |
