Abstract
Oxidation ponds and aerated lagoon is a popular treatment method
for sewage due to the ease of operation and maintenance. In
Malaysia the design of these systems are based mainly on loading
rates or retention time. No attempt have been made to design
based on the kinetics or reactor type. Though the performance of
the oxidation pond is expected to satisfy the Malaysian discharge
standard A and B, studies carried out does not support this
assumption. Actual monitoring data on several sewage treatments
show an efficiency ranging from 32 to 89% for oxidation ponds and
70 to 91% for an aerated lagoon. Data also reveal that
shortcircuiting occurs in the pond thus reducing its efficiency.
