 Wastewater ponds
(sewage stabilization and retention ponds) are essential
for the processing of nutrient-rich effluent wastes of
civilization and agricultural stock. The complex series
of interaction of microorganisms and the exposure to
sunlight and atmospheric gas exchange all play an
important part in the successful degradation of these
wastes. The bound nutrients initially present and the
subsequent release of additional nutrients through
organic decay can cause severe overpopulation and/or
fluctuations in aquatic species present.
Aquatic
plants can be a friend or foe in sewage stabilization
and retention ponds. Balanced populations serve a
function in nutrient removal and oxygenation. However,
severe algal blooms, common to these effluent waters,
can create serious water quality problems. Violations of
discharge standards that can be directly attributed to
excess algal growth often occur. These can include
exceeding limits for suspended solids, BOD, and pH
within discharge water. Rooted and floating plants
within lagoons can impair clarification, settling and
water flow, plus reduce holding capacity. Aquatic plant
management is required to keep these systems operating
legally and efficiently. | |
